13                             INTRODUCTION                                
14        This case is about defendant Meta Platform, Inc.’s alleged use of proprietary computer 
15   code to obtain certain healthcare-related information of Facebook users.  According to plaintiffs, 
16   the Meta Pixel allows Meta to intercept personally identifiable medical information and the 
17   content of patient communications for Facebook users, which Meta then monetizes for its own 
18   financial gain.  Plaintiffs have brought several federal and state law claims to vindicate the harms 
19   that they have allegedly experienced.  They ask me to enjoin Meta from intercepting and 
20   disseminating their patient information.                              
21        Our nation recognizes the importance of privacy in general and health information in 
22   particular: the safekeeping of this sensitive information is enshrined under state and federal law.  
23   The allegations against Meta are troubling: plaintiffs raise potentially strong claims on the merits 
24   and their alleged injury would be irreparable if proven.  To secure a mandatory injunction, 
25   however, plaintiffs need to show “that the law and facts clearly favor [their] position, not simply 
26   that [they are] likely to succeed.”  Garcia v. Google, Inc., 
786 F.3d 733, 740
 (9th Cir. 2015) 
27   (emphasis in original).  Meta’s core defense is that it has systems in place to address the receipt of 
1   for them to take further action.  Without further factual development, it is unclear where the truth 
2   lies, and plaintiffs do not meet the high standard required for a mandatory injunction.  At this early 
3   stage of the case, I DENY the motion for a preliminary injunction.    
4                         FACTUAL BACKGROUND                              
5        Plaintiffs are four Facebook users who are proceeding anonymously due to the sensitive 
6   nature of this litigation.  First Amended Complaint (“FAC”) [Dkt. 22] ¶¶ 32–35.  They allege that 
7   Meta1 improperly acquires their confidential health information in violation of state and federal 
8   law and in contravention of Meta’s own policies regarding use and collection of Facebook users’ 
9   data.  
Id.
 ¶¶ 1–2, 12.  Each of plaintiffs’ healthcare providers—MedStar Health System, Rush 
10   University System for Health, and UK Healthcare—allegedly installed the Meta Pixel on their 
11   patient portals.2  See 
id.
 ¶¶ 3–9.  Plaintiffs claim that when they logged into their patient portal on 
12   their medical provider’s website, the Pixel transmitted certain information to Meta.  
Id.
 ¶¶ 4–9; see 
13   also e.g., id. ¶¶ 86, 122, 146 (describing types of data transmitted by the Pixel).  They contend that 
14   this information, which is contemporaneously redirected to Meta, revealed their status as patients 
15   and was monetized by Meta for use in targeted advertising.  Id. ¶¶ 2, 17–18, 71.   
16          The issues raised in plaintiffs’ motion for a preliminary injunction involve Meta’s alleged 
17   receipt of certain health information through the Meta Pixel; the scope and meaning of certain 
18   terms in Meta’s policies; the strength of plaintiffs’ legal claims; and Meta’s systems to prevent 
19   receipt of this information.  I describe the relevant facts below.     
20        A.   The Meta Pixel’s Technology                                 
21        The Meta Pixel is a free and publicly available piece of code that Meta allows third-party 
22   website developers to install on their websites.  See Declaration of Tobias Wooldridge 
23                                                                         
24                                                                         
25                                                                         
    1 Meta was previously known as Facebook, Inc.  In late 2021, the company changed its name to Meta 
    Platforms, Inc. but the social media platform itself is still known as Facebook.  Opp. at 3 n.2. 

26                                                                         
    2 Some of the medical providers, which are not defendants to the lawsuit, may have since removed the 
27   Pixel: Meta asserts that as of November 23, 2022, the Pixel is not integrated into the patient portals for 
    either Rush University System for Health or UK HealthCare.  See Supplemental Declaration of Tobias 
1   (“Wooldridge Decl.”) [Dkt. 77-4] ¶ 3.3  The Pixel is customizable: website developers choose 
2   which types of user action to measure, and program the Pixel accordingly.  Id. ¶¶ 3–4.  Website 
3   developers in a range of industries use the Pixel.  Id. ¶ 3.  In a nutshell, the Meta Pixel allows 
4   website developers to learn: (1) if and when website users take certain actions on a website, and 
5   (2) generalized information about website users, which can be used for targeting advertising.  Id.  
6   ¶¶ 3–4.                                                               
7        To understand how the Meta Pixel typically works, imagine the following scenario.  A 
8   shoe company wishes to gather certain information on customers and potential customers who 
9   visit its website.  The shoe company first agrees to Meta’s Business Tools Terms (discussed 
10   below), which govern the use of data from the Pixel.  Wooldridge Decl. ¶ 6.  The shoe company 
11   then customizes the Meta Pixel to track, say, every time a site visitor clicks on the “sale” button on 
12   its website, which is called an “Event.”  Id. ¶ 4.  Every time a user accesses the website and clicks 
13   on the “sale” button (i.e., an “Event” occurs), it triggers the Meta Pixel, which then sends certain 
14   data to Meta.  Id.  Meta will attempt to match the customer data that it receives to Meta users—
15   Meta cannot match non-Meta users.  Id.  The shoe company may then choose to create “Custom 
16   Audiences” (i.e., all of the customers and potential customers who clicked on the “sale” button) 
17   who will receive targeted ads on Facebook, Instagram, and publishers within Meta’s Audience 
18   Network.  Id.  Meta may also provide the shoe company with de-identified, aggregated 
19   information so the shoe company understands the impact of its ads by measuring what happens 
20   when people see them.  Id.  Meta does not reveal the identity of the matched Meta users to the 
21   shoe company.  Id.                                                    
22        Now, imagine that same process occurring but instead of a shoe company, substitute 
23   MedStar Health System, plaintiff John Doe’s medical provider.  Plaintiffs’ expert, Richard Smith, 
24   who submitted a lengthy declaration in conjunction with the preliminary injunction motion, 
25   asserted that MedStar Health System has the Meta Pixel on various pages of its website, 
26   www.MedStarHealth.org.  See Declaration of Richard M. Smith (“Smith Decl.”) [Dkt. 49] ¶ 19; 
27                                                                         
1   FAC ¶¶ 3–5; see also Supplemental Declaration of Tobias Wooldridge (“Supp. Wooldridge 
2   Decl.”) [Dkt. 143-3] ¶ 4 (explaining that the Pixel is integrated into the MedStar page that allows 
3   users to navigate to the login page).  Plaintiffs allege that when John Doe or any other patient of 
4   MedStar presses the login button to enter their MedStar patient portal using their username or 
5   email address and password, the Meta Pixel source code causes Doe’s and all other patients’ 
6   computing devices to re-direct the contents of their respective patient portal login communications 
7   to Meta and then to MedStar, rather than just to MedStar.  See Smith Decl. ¶¶ 27–28.  Meta 
8   allegedly redirects the patient portal login information to itself via a “SubscribedButtonClick” 
9   transmission that includes, among other things:                       
10            •  The patient’s identity in the form of cookies, IP address, and User-Agent 
11              identifiers;                                               
12            •  Content of the button (“Log in”);                         
13            •  Contents of the page from which the patient clicked to log in to the patient 
14              portal; and                                                
15            •  Content of the page the patient will land as a result of clicking “Log in” to the 
16              patient portal.                                            
17   Id. ¶¶ 31–33.  As a patient browses through the MedStar website, the Meta Pixel allegedly 
18   continues to transmit information to Meta, including information about doctors, medical 
19   conditions, and appointments associated with a patient’s session.  Motion for Preliminary 
20   Injunction (“Mot.”) [Dkt. 46] at 4; Smith Decl. ¶¶ 97, 130–31.4       
21        Plaintiffs assert that Meta monetizes the information that it receives through the Meta Pixel 
22   by using it to generate highly-profitable targeted advertising on- and off–Facebook.  Notice of 
23   Motion (“Not. of Mot.”) at 1; FAC ¶ 17.  They claim that Meta can target ad campaigns to patients 
24   based on patients’ browsing behavior on their medical providers’ website.  FAC ¶¶ 18–19; see 
25                                                                         

26                                                                         
    4 According to Meta, the Pixel is not integrated into the MedStar login page itself.  See Supp. Wooldridge 
27   Decl. ¶ 4.  Meta acknowledges, though, that as of November 2022 the Meta Pixel was integrated into the 
    https://www.medstarhealth.org/mymedstar-patient-portal page, and that website users may click the “log 
1   also Wooldridge Decl. ¶ 4 (explaining that website developers can target ads on Facebook, 
2   Instagram, and other sites based on data transmitted by the Pixel).  Meta may, for instance, target 
3   ads to a person who has (1) used the patient portal and (2) viewed a page about a specific 
4   condition, such as cancer.  FAC ¶ 19.  These allegations appear to be borne out by plaintiffs’ 
5   expert’s experiences: after Smith visited five hospital websites which employ the Meta Pixel, he 
6   allegedly received many new health-related advertisements.  Smith Decl. ¶ 187; see also ¶ 188 
7   (providing over a dozen examples of health-related advertisements).  In particular, Smith noticed 
8   that within two hours of searching for information on ulcerative colitis on one of the hospitals’ 
9   websites, he was shown an advertisement related to ulcerative colitis in his Facebook video feed.  
10   Id. ¶¶ 189–90.                                                        
11        According to plaintiffs, they have identified more than 660 entities covered under the 
12   Health Insurance Portability and Accountability Act (“HIPAA”), from which Meta is receiving 
13   information.  Mot. at 2; FAC ¶ 15.                                    
14        B.   Meta’s Data Policies                                        
15        Meta has several policies governing how it collects and uses data, including through the 
16   Pixel.  When individuals sign up for a Facebook account, they agree to Meta’s Terms of Service, 
17   Data Policy, and Cookies Policy.  FAC ¶ 49.  These policies are contractually binding on both 
18   Meta and its users.  Id.  Because these policies bear on the important question of whether plaintiffs 
19   knew and consented to Meta’s use of the Meta Pixel to receive health-related information, I 
20   describe each policy below.                                           
21             1.   Terms of Service                                       
22        The Terms of Service govern the “use of Facebook, Messenger, and the other products, 
23   features, apps, services, technologies, and software” that Meta offers.  See Declaration of Abigail 
24   Barrera (“Barrera Decl.”) Ex. A (Terms of Service) [Dkt. 76-3] at 1.  Meta informs users that it 
25   “use[s] data about the connections you make, the choices and settings you select, and what you 
26   share and do on and off our Products – to personalize your experience.”  Id. at 2.  The Terms of 
27   Service explain that Meta shows users “personalized ads, offers, and other sponsored or 
1   many businesses and organizations that use Facebook and other Meta Products.”  Id.  To provide 
2   these services, Meta’s terms explain, Meta “collect[s] and use[s] your personal data.”  Id. at 4.  
3   The Terms of Service include several links to the Data Policy.  Id. at 1, 3, 4. 
4             2.   Data Policy                                            
5        The Data Policy5 “describes the information” that Meta “process[es] to support Facebook, 
6   Instagram, Messenger and other products and features offered by Meta.”  Barrera Decl., Ex. B 
7   (Data Policy) [Dkt. 76-4] at 1.  Among other things, the Data Policy tells users that: 
8                                                                         
              Advertisers, app developers, and publishers can send us information 
9                                                                         
              through Meta Business Tools they use, including our social plug-ins 
10             (such as the Like button), Facebook Login, our APIs and SDKs, or 
              the Meta pixel.  These partners provide information about your 
11             activities off of our Products—including information about your 
              device, websites you visit, purchases you make, the ads you see, and 
12             how you use their services—whether or not you have an account or 
              are logged into our Products.  For example, a game developer could 
13                                                                         
              use our API to tell us what games you play, or a business could tell 
14             us  about  a  purchase  you  made  in  its  store.    We  also  receive 
              information about your online and offline actions and purchases 
15             from third-party data providers who have the rights to provide 
              us with your information.

              Partners receive your data when you visit or use their services or 
17                                                                         
              through third parties they work with.  We require each of these 
18             partners to have lawful rights to collect, use and share your data 
              before providing any data to us.

    Id. at 4–5 (emphasis added).  The Data Policy also notifies users that Meta uses this information 
20

2   allow Meta to do so.  Id. at 9.                                       
3             3.   Cookies Policy                                         
4        Cookies are “small pieces of text used to store information on web browsers.”  Barrera 
5   Decl., Ex. C (Cookies Policy) [Dkt. 76-5] at 1.  They “store and receive identifiers and other 
6   information on computers, phones and other devices,” and they can serve a number of different 
7   functions, such as “personalizing content, tailoring and measuring ads, and providing a safer 
8   experience.”  Id. at 1.                                               
9        Meta’s Cookies Policy explains that Meta “use[s] cookies if you have a Facebook account, 
10   use the Meta Products, including our website and apps, or visit other websites and apps that use 
11   the Meta Products (including the Like button).”  Id.  Meta notes that cookies allow it to 
12   “understand the information that we receive about you, including information about your use of 
13   other websites and apps, whether or not you are registered or logged in,” and that it “use[s] 
14   cookies to help us show ads and to make recommendations for businesses and other organisations 
15   to people who may be interested in the products, services or causes they promote.”  Id. at 1–2.  
16   Cookies allow Meta “to provide insights about the people who use the Meta Products, as well as 
17   the people who interact with the ads, websites and apps of our advertisers and the businesses that 
18   use the Meta Products.”  Id. at 3.  The policy also describes the cookie used to enable the Meta 
19   Pixel (“_fbp”) and explains that Meta’s “business partners may also choose to share information 
20   with Meta from cookies set in their own websites’ domains, whether or not you have a Facebook 
21   account or are logged in.”  Id. at 4; see also id. at 4–5 (“Meta uses cookies and receives 
22   information when you visit [websites and apps that use the Meta Products], including device 
23   information and information about your activity, without any further action from you.  This occurs 
24   whether or not you have a Facebook account or are logged in.”).       
25             4.   Business Tools Terms and the Pixel Creation Process    
26        Meta also has policies which govern third-party website developers’ use of the Meta Pixel.  
27   Before a website developer can integrate the Pixel on a website, the developer must agree to 
1        The Business Tools Terms require developers to “represent and warrant that you (and any 
2   data provider that you may use) have all of the necessary rights and permissions and a lawful basis 
3   (in compliance with all applicable laws, regulations and industry guidelines) for the disclosure and 
4   use of Business Tool Data.”  Barrera Decl., Ex. D (Business Tools Terms) [Dkt. 76-6] at 1.  
5   Developers must also “represent and warrant that [they] have provided robust and sufficiently 
6   prominent notice to users regarding the Business Tool Data collection, sharing and usage,” 
7   including a “clear and prominent notice on each web page where [Meta] pixels are used that links 
8   to a clear explanation [of] . . . how users can opt-out of the collection and use of information for ad 
9   targeting [].”  Id. at 3.  As a condition of using the Pixel, developers specifically agree that they 
10   will “not share Business Tool Data . . . that [they] know or reasonably should know . . . includes 
11   health, financial information or other categories of sensitive information (including any 
12   information defined as sensitive under applicable laws, regulations and applicable industry 
13   guidelines).”  Id. at 2 (emphasis added); see also Barrera Decl., Ex. E (Commercial Terms) [Dkt. 
14   76-7] at 2 (similar provision in Commercial Terms).                   
15        During the Meta Pixel ID creation process, Meta reminds developers not to send sensitive 
16   user data to Meta.  Wooldridge Decl. ¶ 7.  Meta has published several articles that explain and 
17   give examples of the kinds of information (including health information) that developers should 
18   not send to Meta, provide steps that developers can take to avoid sending such information, and 
19   describe how to address instances in which sensitive information may have been sent.  Id.    
20        C.   User Control and Meta’s Filtering Mechanism                 
21        Finally, outside of the policies discussed above, there are two technological tools that bear 
22   on the matter at hand.                                                
23        First, Meta gives users the ability to control the use of information about their off-
24   Facebook activity (such as activity on third-party websites) for advertising purposes.  Wooldridge 
25   Decl. ¶ 11.  The Off-Facebook Activity tool allows users to view a summary of information that 
26   Meta has received about their activity from third parties through the Business Tools, including the 
27   Pixel.  Id.  Users can “disconnect” the off-Facebook activity that has been associated with their 
1   storage of any future connections for all third-party websites (or on a website-by-website basis).  
2   Id.  The “Data About Your Activity From Partners” tool also allows users to opt out of receiving 
3   personalized advertisements based on their activities on other websites and apps.  Id. ¶ 12; see also 
4   Barrera Decl., Exs. F, G, H, I (collecting screenshots and articles regarding these tools).  
5   Importantly, Meta does not assert that these tools allow users to prevent their information from 
6   being sent to Meta in the first place.  See Reply at 3 (“[N]owhere in Meta’s Opposition does it 
7   represent that patients can prevent Facebook from receiving [their data].”). 
8        Second, Meta uses a filtering mechanism6 which attempts to screen out potentially 
9   sensitive health data that Meta receives.  Wooldridge Decl. ¶ 8.  It developed the filter to detect 
10   data—including health data—sent through the Pixel that Meta categorizes as potentially sensitive.  
11   According to Meta, the filter prevents any such data that it detects from being ingested into its ads 
12   ranking and optimization systems.  Id.  When it filters out data, it notifies the developer that Meta 
13   detected and blocked data that may not comply with Meta’s policies.  Id. ¶ 9.  These notifications 
14   provide details about the affected data, including the URL where the events occurred, the location 
15   of the potentially violating information, steps that the developer can take to address the issue, and 
16   an email address to contact with questions.  Id.                      
17                        PROCEDURAL BACKGROUND                            
18        This case is one of seven consolidated putative class actions involving the Meta Pixel that 
19   are currently before me.  Plaintiffs in the present case filed suit in June 2022.  Dkt. 1.  On July 15, 
20   2022, plaintiffs filed the FAC, which is currently the operative pleading.  See FAC.  They bring 
21   eight claims: (1) breach of contract, id. ¶¶ 108–23; (2) breach of the implied warranty of good 
22   faith and fair dealing; id. ¶¶ 124–30; (3) intrusion upon seclusion and constitutional invasion of 
23   privacy; id. ¶¶ 131–38; (4) violation of the Electronic Communications Privacy Act (“ECPA”); id. 
24   ¶¶ 139–55; (5) violation of the California Invasion of Privacy Act (“CIPA”); id. ¶¶ 156–65; (6) 
25   negligent misrepresentation; id. ¶¶ 166–73; (7) violation of California’s Unfair Competition Law; 
26                                                                         
27                                                                         
    6 The details of this filtering mechanism have been filed under seal.  See, e.g., Wooldridge Decl. ¶ 8; Supp. 
    Wooldridge Decl. ¶¶ 13–14, 19–20, 24–25.  As discussed in the concurrently filed order granting the 
1   id. ¶¶ 174–87; and (8) trespass, id. ¶¶ 188–99.                       
2        On August 25, 2022, plaintiffs filed the instant motion for a preliminary injunction, which 
3   rests on plaintiffs’ claims under the ECPA, CIPA, and California tort law.  See Mot. at 1.  As part 
4   of their motion, they seek an order that: (1) “[p]rohibits Meta from intercepting patient 
5   information and communications from HIPAA-covered entities through its use of the Meta Pixel” 
6   and (2) “[p]rohibits Meta from disseminating and/or using patient information and 
7   communications that it has intercepted from HIPAA-covered entities through its use of the Meta 
8   Pixel.”  Not. of Mot. at 1.  In conjunction with the opening motion, they submitted declarations by 
9   plaintiff John Doe and their expert Richard Smith, a legal consultant who specializes in the 
10   analysis of software systems.  Dkts. 47, 49.  Plaintiffs also submitted copies of five decisions from 
11   state courts that have found that similar claims may lie against medical providers based on their 
12   use of the Pixel.  See Declaration of Jason Barnes (“Barnes Decl.”) [Dkt. 48] ¶¶ 5–10.7    
13        In opposition, Meta included a declaration by Tobias Wooldridge, a senior software 
14   engineer at Meta, which addressed technical aspects of the Pixel and described Meta’s filtration 
15   system, among other things.  See Wooldridge Decl. ¶¶ 4, 8–9.  With their reply, plaintiffs included 
16   a declaration by Christopher Wilson, a computer sciences professor who holds positions at 
17   Northeastern University and Harvard University, who opined that Meta could, with slight 
18   modifications, use its existing filtering system and other tools to comply with an injunction of the 
19   sort that plaintiffs seek.  See Declaration of Christopher Wilson (“Wilson Decl.”) [Dkt. 98] ¶¶ 1, 
20   6–8, 10–20.  Meta objected that the Wilson Declaration was new evidence improperly submitted 
21   on reply.  See Meta’s Objections [Dkt. 111] at 1.  At the hearing, I allowed Meta the opportunity 
22   to submit a supplemental declaration that addressed the issues raised in the Wilson Decl.  See 
23   November 14, 2022 Order [Dkt. 133] at 1.  Meta then filed the Supp. Wooldridge Decl., and 
24                                                                         

25                                                                         
    7 These claims include: (1) a claim under the Maryland Wiretap Act, (2) a claim under the Massachusetts 
26   Wiretap Act; (3) claims under the California Invasion of Privacy Act; (4) intrusion upon seclusion; (5) 
    publication of private facts; and (6) Biddle claims.  Barnes Decl. ¶¶ 5–10.  (Biddle claims refer to the Ohio 
27   Supreme Court decision, Biddle v. Warren Gen. Hosp., 
86 Ohio St. 3d 395
 (1999), which established a 
    common law tort under Ohio law for the unauthorized, unprivileged disclosure to a third party of nonpublic 
1   plaintiffs subsequently submitted supplemental authority consisting of new guidance issued by the 
2   Office for Civil Rights at the U.S. Department of Health and Human Services on December 1, 
3   2022, regarding the obligations of HIPAA on certain entities when using online tracking 
4   technologies, including the Meta Pixel.  See Supp. Wooldridge Decl.; Plaintiffs’ Notice of 
5   Supplemental Authority [Dkt. 148] at 2.                               
6        After full briefing and argument, my ruling follows.

21                               DISCUSSION                                
22        My decision to deny the pending motion is based on Meta’s evidence that it is doing all it 
23   can to minimize the problems raised by plaintiffs, and the need for discovery to clarify both the 
24   scope of the problems and potential solutions for them.  But as the discussion below suggests, it 
25   appears that plaintiffs have plausible claims that may well succeed on the merits if that hurdle is 
26   overcome, and that the injury alleged is irreparable.                 
27        Before I address Meta’s substantive challenges to the motion, I will dispense with a 
1   filed at some point in the future, moots plaintiffs’ motion.  See Opposition (“Opp.”) [Dkt. 77-3] at 
2   10–11.  It cites authority standing for the unremarkable principle that “[i]t is well-established” in 
3   the Ninth Circuit “that an amended complaint supersedes the original, the latter being treated 
4   thereafter as non-existent.”  Ramirez v. Cnty. of San Bernardino, 
806 F.3d 1002, 1008
 (9th Cir. 
5   2015) (internal citation and quotation marks omitted).  It also cites my order establishing that the 
6   consolidated complaint shall be the operative complaint in the consolidated action.  Opp. at 10 
7   (citing October 12, 2022 Order) [Dkt. 73] at 3.                       
8        Meta is missing the point.  Yes, at some point a consolidated complaint will be filed and at 
9   that point, the FAC will no longer be the operative pleading.  That has not happened yet.  None of 
10   Meta’s cases support its novel theory that a motion for a preliminary injunction based on a 
11   currently operative complaint is mooted by a currently non-existent consolidated complaint.  I 
12   note, too, that all of the plaintiffs from the consolidated and soon-to-be consolidated cases agreed 
13   that the preliminary injunction briefing and hearing should proceed despite the cases being 
14   consolidated.  See Dkts. 65, 94, 95.  I need to address plaintiffs’ motion on the merits.  Having 
15   determined that the motion is not moot, I turn to the four Winter factors.   
16   I.     LIKELIHOOD OF SUCCESS ON THE MERITS                            
17        Because plaintiffs’ purported consent is an overarching issue that could preclude relief for 
18   all of the claims at issue, I begin with this topic.                  
19        A.   Plaintiffs Did Not Consent to Meta’s Acquisition of Their Health Information. 
20        The key question at the heart of this motion is whether a reasonable user would have 
21   understood from Meta’s policies that Meta collects the health information at issue here.  Plaintiffs 
22   contend that the information at issue constitutes “protected health information” within the 
23   meaning of HIPAA, and as a result, HIPAA’s heightened standard for consent applies.  Mot. at 14.  
24   I agree that the information at issue here appears to show patient status and thus constitutes 
25   protected health information under HIPAA.  But I do not reach the question of whether HIPAA’s 
26   heightened standard for consent applies because, as set forth below, I do not believe that a 
27   reasonable user would have understood that Meta may intercept their health information.   
              1.   The Meta Pixel Captures Information Showing Patient Status.   
1                                                                         
         Plaintiffs contend that the Pixel sends information revealing patient status because it 
2                                                                         
    intercepts data relating to patient portal logins and logouts alongside identifiers for each patient.  
3                                                                         
    Mot. at 6.  I agree.                                                  
4                                                                         
         Plaintiffs have put forward evidence that the Pixel transmits “the patient status of 
5

         With the MedStar Health page as an example, I conclude that the Pixel transmits 
19                                                                         
    information showing patient status.  That is, the act of clicking the “Log in” button, when coupled 
20                                                                         
    with the MedStar Health patient portal URL and the other information transmitted by the Pixel, 
21                                                                         
    sufficiently identifies the website user as a patient.   Next, I consider whether patient status 
22                                                                         
    constitutes protected health information under HIPAA.                 
23                                                                         
              2.   Patient Status Is Protected Health Information.        
24                                                                         
         HIPAA defines “protected health information” as “individually identifiable” information 
25                                                                         
    that is “created or received by a health care provider” (or similar entities) that “[r]elates to the past, 
26                                                                         
    present, or future physical or mental health or condition of an individual” or the “provision of 
27                                                                         
    health care to an individual.”  
45 C.F.R. § 160.103
.  At least one court has previously found that 
1   information which shows patient-status constitutes protected health information.  See Arvidson v. 
2   Buchar, No. ST-16-cv-410, 
2018 WL 10613032
, at *10 (V.I. Super. Ct. June 6, 2018) (ruling that 
3   patient names and a patient list were PHI which were therefore subject to special disclosure 
4   requirements under HIPAA).  And the Department of Health and Human Services has issued 
5   guidance—including as recently as this past month—instructing that information which connects 
6   an individual with a healthcare provider “is indicative that the individual has received or will 
7   receive health care services,” and thus “relates to the individual’s past, present, or future health or 
8   health care or payment for care.”  See Use of Online Tracking Technologies by HIPAA Covered 
9   Entities and Business Associates, U.S. Health & Human Services (content current as of Dec. 1, 
10   2022), https://www.hhs.gov/hipaa/for-professionals/privacy/guidance/hipaa-online-

78 Fed. Reg. 5642
 (Jan. 25, 2013) (observing that it would be a 
12   HIPAA violation for a covered entity to disclose a list of patient names, addresses, and hospital 
13   identification numbers because “the protected health information is obviously identifiable”).   
14        Meta does not challenge plaintiffs’ assertion that patient status is protected information 
15   under HIPAA, but instead relies on Smith v. Facebook, 
262 F. Supp. 3d 943
 (N.D. Cal. 2017).  But 
16   Smith does not forestall my conclusion that patient status is protected health information.  It dealt 
17   with the question of whether Facebook users had consented to Facebook collecting information 
18   about them via their browsing through certain health-related websites (such as 
19   http://www.cancer.net) that had an embedded Facebook “Like” button.  Smith, 
262 F. Supp. 3d at 20
   948.  Smith concluded that there was no protected health information because the information 
21   transmitted to Facebook when a user visited the http://www.cancer.net page was the same kind of 
22   information transmitted to Facebook any time a user visited any page on the internet that 
23   contained a Facebook button.

.  In other words, the URLs did not “relate[] specifically to 
24   Plaintiffs’ health.”

              or  automated  crawler  that  sends  GET  requests  to  these  URLs. 
4             Nothing about the URLs, or the content of the pages located at those 
              URLs, relates “to the past, present, or future physical or mental 
5

45 C.F.R. § 6
             160.103 (emphasis  added).   As  such,  the  stricter  authorization 
              requirements of HIPAA (as well as 
Cal. Civ. Code § 1798.91
) do 
7             not apply.

         This case is different than Smith.  Unlike the “general health information that is accessible 
10

    Smith, then, the Pixel captures information that connects a particular user to a particular healthcare 
13

    HIPAA.   Smith involved users browsing through websites providing healthcare information to the 
15                                                                         
    public at large, not users navigating to patient portals on healthcare providers’ websites.  The act 
16

    browsing contemplated in Smith.  As a result, Smith does not bear on the question of whether the

    information at issue here constitutes patient health information.

              3.   Meta Has Not Established Consent to the Conduct at Issue.

24

    that Meta’s “business partners may also choose to share information with Meta”).  Meta’s policies 
26

    users’ interactions with their medical providers’ websites.  Its generalized notice is not sufficient 
1   to establish consent.                                                 
2        Consent “can be explicit or implied, but any consent must be actual.”  In re Google, Inc., 
3   
2013 WL 5423918
, at *12 (N.D. Cal. Sept. 26, 2013) (citation omitted).  “In order for consent to 
4   be actual, the disclosures must ‘explicitly notify’ users of the practice at issue.”  Calhoun v. 
5   Google LLC, 
526 F. Supp. 3d 605
, 620 (N.D. Cal. 2021) (internal quotation omitted); see also 
6   Campbell v. Facebook, Inc., 
77 F. Supp. 3d 836
, 847–48 (N.D. Cal. 2014) (explaining that, for a 
7   finding of consent, the disclosures must have given users notice of the “specific practice” at issue).  
8   As the Restatement explains, “[i]n order to be effective, the consent must be to the particular 
9   conduct of the actor, or to substantially the same conduct.”  Restatement (Second) of Torts § 892A 
10   (1979).  In other words, “consent to a fight with fists is not consent to an act of a very different 
11   character, such as biting off a finger, stabbing with a knife, or using brass knuckles.”  Id.  The test 
12   is whether a reasonable user who viewed Meta’s disclosures would have understood that Meta was 
13   collecting the information at issue.  See Perkins v. LinkedIn Corp., 
53 F. Supp. 3d 1190
, 1212 
14   (N.D. Cal. 2014).  Meta has the burden to show consent.  Calhoun, 526 F. Supp. 3d at 620.   
15        First, I am skeptical that a reasonable user who viewed Meta’s policies would have 
16   understood that Meta was collecting protected health information.9  The nature of the data 
17   collection that plaintiffs agreed to is akin to the general internet browsing at issue in Smith; the 
18   collection of protected health information from a medical provider is a different matter entirely.   
19        Second, even if a reasonable Facebook user would have understood that Meta’s data 
20   collection included health information from their medical provider, that must still be squared with 
21   its representation that it “requires” any third-party to have “lawful rights to collect, use and share 
22   your data before providing any data to us.”  Data Policy at 5.  For purposes of the likely 
23   forthcoming motion to dismiss, I note that Meta’s policies “must have only one plausible 
24   interpretation for a finding of consent.”  Calhoun, 526 F. Supp. 3d at 620 (citation omitted); see 
25                                                                         

26                                                                         
    9 This is especially true because other Meta policies (such as the Business Tool Terms) expressly provide 
27   that website developers will not share data that they “know or reasonably should know . . . includes health, 
    financial or other categories of sensitive information (including any information defined as sensitive under 
1   also In re Facebook, Inc., Consumer Priv. User Profile Litig., 
402 F. Supp. 3d 767
, 794 (N.D. Cal. 
2   2019) (internal citation omitted) (hereinafter “Facebook Consumer Priv. Litig.”) (denying 
3   Facebook’s motion to dismiss based on plaintiffs’ purported consent where there were multiple 
4   plausible interpretations of the term “allowed”).  In Meta’s view, the Data Policy provision is 
5   satisfied because any third party that wishes to use the Pixel must “represent and warrant” to Meta 
6   that the third party has “all of the necessary rights and permissions and a lawful basis (in 
7   compliance with all applicable laws, regulations, and industry guidelines) for the disclosure and 
8   use” of the data.  Opp. at 19 (citing Business Tool Terms at 1).   But “require” is susceptible to 
9   multiple meanings.  It could mean, for instance, that all developers using the Meta Pixel have told 
10   Meta that they may lawfully share this information with them.  This is, of course, Meta’s preferred 
11   interpretation.  But it could also mean that—in the context of the health information at issue 
12   here—Meta required a HIPAA-compliant authorization before receiving such information.  In 
13   light of the multiple plausible interpretations of “require,” it is unlikely that Meta will be able to 
14   establish that plaintiffs consented to the data collection at issue here.  
15        In sum, it does not appear to me that consent will bar plaintiffs’ claims.  I go on to consider 
16   the strength of plaintiffs’ claims under the Wiretap Act, CIPA, and California law.         
17        B.   Wiretap Act Claim                                           
18        There are two questions that I must answer to determine whether plaintiffs are likely to 
19   prevail on their Wiretap Act claim.  First, I must examine whether plaintiffs have shown that each 
20   of the five elements are met.  Second, I must consider whether any of the Wiretap Act’s 
21   exceptions could exempt Meta from liability.  I address each question below. 
22                  1.  Elements of a Wiretap Act Claim                    
23        “The Wiretap Act prohibits the unauthorized ‘interception’ of an ‘electronic 
24   communication.’”  In re Facebook, Inc. Internet Tracking Litig., 
956 F.3d 589
, 606–07 (9th Cir. 
25   2020), cert. denied sub nom. Facebook, Inc. v. Davis, 
141 S. Ct. 1684
 (2021) (quoting 
18 U.S.C. § 26
   2511(1)(a)–(e)).  Plaintiffs must show that Meta (1) intentionally (2) intercepted (3) the contents 
27   of (4) plaintiffs’ electronic communications (5) using a device.  See In re Pharmatrak, Inc., 329 
1 F.3d 9, 18
 (1st Cir. 2003) (listing elements for a Wiretap Act claim).  Meta challenges only the 
2   “contents” element.                                                   
3                  a.   Meta’s “Intentional” “Interception”               
4        “Intercept” is defined under the Wiretap Act as “the aural or other acquisition of the 
5   contents of any wire, electronic, or oral communication through the use of any electronic, 
6   mechanical, or other device.” 
18 U.S.C. § 2510
(4).  Although the statute does not define 
7   “acquisition,” the Ninth Circuit has construed the term according to its ordinary meaning as the 
8   “act of acquiring, or coming into possession of [.]”  United States v. Smith, 
155 F.3d 1051
, 1055 
9   n.7 (9th Cir. 1998). “Such acquisition occurs when the contents of a wire communication are 
10   captured or redirected in any way.”  Noel v. Hall, 
568 F.3d 743, 749
 (9th Cir. 2009) (internal 
11   citation and quotation marks omitted).                                
12        According to plaintiffs, the Pixel is “designed for the very purpose of intercepting 
13   communications on third-party websites by surreptitiously and contemporaneously redirecting 
14   these communications to Meta.”  Mot. at 11 (citing Smith Decl. ¶¶ 7–14).  Plaintiffs have put 
15   forward evidence that Meta receives information through the Pixel.  See, e.g., Smith Decl. ¶¶ 4–5, 
16   32–33.  Meta does not dispute that the intentional or interception elements are met.  See Opp. at 
17   20–21.  Plaintiffs appear likely to succeed on these two elements of their claim.      
18                  b.   “Contents” of “Electronic Communications” on “Devices” 
19        Of the remaining three elements, only “contents” is in dispute.  Meta says that the names 
20   of buttons clicked on websites and their associated URLs are not “content” within the meaning of 
21   the statute.  I disagree.  As set forth below, because the “Log in” button and full-string URLs 
22   concern the “substantive, purport, or meaning of a communication,” these transmissions likely 
23   constitute “contents.”                                                
24        The statute broadly defines “content” to include “any information concerning the 
25   substance, purport, or meaning of [a] communication.”  
18 U.S.C. § 2510
(8).  “Contents” refers to 
26   the “intended message conveyed by the communication”—it does not include record information 
27   regarding the characteristics of the message that is generated in the course of the communication. 
1   provided as part of a sign-up process constitutes “content” because this information is the subject 
2   of the communication.  
Id. at 1107
 (“Because the users had communicated with the website by 
3   entering their personal medical information into a form provided by the website, the First Circuit 
4   correctly concluded that the defendant was disclosing the contents of a communication.”).  And 
5   while a URL that includes “basic identification and address information” is not “content,” a URL 
6   disclosing a “search term or similar communication made by the user” “could constitute a 
7   communication” under the statute.  
Id.
 at 1108–09.                    
8        In my view, the log-in buttons and the kinds of descriptive URLs identified in the Smith 
9   Decl. are “contents” within the meaning of the statute.  Unlike in Zynga, the URLs at issue here 
10   would not merely reveal the name of a Facebook user or group—as Smith explained, the 
11   transmitted URLs include both the “path” and the “query string.”10  Smith Decl. ¶¶ 50–51; see 
12   also 
id. ¶ 189
 (showing hardfordhospital.org/services/digestive-health/conditions-we-
13   treat/colorectal-small-bowel-disorders/ulcerative-colitis URL).  These items are content because 
14   they concern the substance of a communication.  See Zynga, 750 F.3d at 1107; In re Google Inc. 
15   Cookie Placement Consumer Priv. Litig., 
806 F.3d 125, 137
 (3d Cir. 2015) (“If an address, phone 
16   number, or URL is . . . part of the substantive information conveyed to the recipient, then by 
17   definition it is ‘content.’”); see also In re Google RTB Consumer Priv. Litig., No. 21-cv-2155-

5        Importantly, the Wiretap Act exempts liability in certain circumstances.  The statute 
6   provides that:                                                        
7                                                                         
              It shall not be unlawful under this chapter for a person not acting 
8                                                                         
              under  color  of  law  to intercept a  wire,  oral,  or electronic 
9             communication where such person is a party to the communication 
              or where one of the parties to the communication has given prior 
10             consent  to  such  interception  unless  such  communication  is 
              intercepted for the purpose of committing any criminal or tortious 
11             act in violation of the Constitution or laws of the United States or of 
              any State.

18 U.S.C. § 2511
(2)(d).  In other words, the Wiretap Act allows interception where the

    interception is made by a “party” to the communication or where a “party” has consented to the 
15                                                                         
    interception.

  This exception does not apply, however, where the interceptor acts “for the 
16

         Putting the question of plaintiffs’ consent to the side, the healthcare providers who 
18

    Because the Wiretap Act is a one-party consent statute, see Rodriguez v. Google LLC, No. 20-cv-

         The Ninth Circuit has explained that the crime-tort exception to the Wiretap Act’s consent 
25                                                                         
    defense focuses on whether “the purpose for the interception—its intended use—was criminal or 
26                                                                         
    tortious.”  Sussman v. Am. Broad. Companies, Inc., 
186 F.3d 1200, 1202
 (9th Cir. 1999) 
27

Id.
  Under this 
2   exception, plaintiffs must allege that either the “primary motivation or a determining factor in [the 
3   defendant’s] actions has been to injure plaintiffs tortiously.”  Brown v. Google LLC, 
525 F. Supp. 4
   3d 1049, 1067 (N.D. Cal. 2021) (quotation omitted).                   
5        To ultimately succeed on this claim, plaintiffs must show that the purpose for Meta’s 
6   interception was to injure plaintiffs tortiously.  Meta contends that the crime-tort exception does 
7   not apply because its purpose was merely advertising, which is neither a crime nor a tort.  Opp. at 
8   20.  Multiple courts in this district have found that the crime-tort exception to the Wiretap Act is 
9   inapplicable where the defendant’s primary motivation was to make money, not to injure plaintiffs 
10   tortiously.  See Rodriguez, 
2021 WL 2026726
, at *6 n.8 (finding crime-tort exception inapplicable 
11   where Google’s alleged interceptions occurred with the consent of app developers and were 
12   financially motivated); In re Google Inc. Gmail Litig., No. 13-md-02430-LHK, 
2014 WL 13
   1102660, at *18 n.13 (N.D. Cal. Mar. 18, 2014) (“[T]he tort or crime exception cannot apply 
14   where the interceptor’s ‘purpose has plainly not been to perpetuate torts on millions of Internet 
15   users, but to make money.’”) (internal citation omitted).             
16        Plaintiffs respond that the use of patient data for advertising in the absence of express 
17   written consent is criminal and tortious.  Reply at 11; see also FAC ¶ 154 (alleging that Meta had 
18   a tortious purpose in acquiring the content of patient communications related to patient portals).  
19   Plaintiffs cite several state court decisions establishing that tort claims may lie against health care 
20   providers over their use of the Pixel.  Reply at 11.  And as discussed in Part I.D. infra, plaintiffs’ 
21   tort claims against Meta appear viable.  There is a not-insignificant chance, then, that plaintiffs 
22   may be able to show that the crime-tort exception applies.  Cf. Brown, 525 F. Supp. 3d at 1067 
23   (finding that the crime-tort exception may apply where plaintiffs had “adequately alleged that 
24   Google’s association of their data with preexisting user profiles violated state law, including 
25   CDAFA, intrusion upon seclusion, and invasion of privacy”).           
26        That said, in light of the authority in this district finding that liability does not lie where a 
27   defendant’s primary motivator was to make money, I am not convinced that plaintiffs have met 
1   Of course, this claim will present differently in a motion to dismiss context.  The parties will have 
2   the opportunity to refine their arguments regarding Meta’s purpose in intercepting the information 
3   at issue here later in the litigation.

5        The California Invasion of Privacy Act (“CIPA”) mirrors the federal Wiretap Act, but with 
6   a few important exceptions.  “The purpose of the act was to protect the right of privacy by, among 
7   other things, requiring that all parties consent to a recording of their conversation.”  Flanagan v. 
8   Flanagan,

 (2002).                                
9        Plaintiffs allege that Meta violated two provisions of CIPA: section 631(a) (the 
10   wiretapping provision), and section 632(a) (the recording provision).  Mot. at 15–16.  The 
11   wiretapping provision of CIPA provides:                               
12

5             1.   Elements of CIPA Claim (Wiretapping Provision)         
6        “The analysis for a violation of CIPA is the same as that under the federal Wiretap Act.”  
7   Brodsky v. Apple Inc., 
445 F. Supp. 3d 110
, 127 (N.D. Cal. 2020) (quoting Cline, 
329 F. Supp. 3d 8 at 1051
).  I have already concluded that plaintiffs will likely establish the elements of a claim 
9   under the federal Wiretap Act.  See Section I.B.1 supra.  Meta mounts a single challenge to a 
10   single element here, arguing that plaintiffs cannot show that the intercepted information is 
11   “content” based on its arguments under the federal Wiretap Act.  See Opp. at 21.  For the reasons 
12   given above, this challenge fails.                                    
13             2.   Elements of CIPA Claim (Recording Provision)           
14        As noted above, section 632(a) applies only to eavesdropping or recording of a 
15   confidential communication.  See 
Cal. Penal Code § 632
(a).  Meta argues that the communications 
16   at issue here were not confidential because they were transmitted via the Internet.  Opp. at 21–22.  
17   I disagree.                                                           
18        A communication is confidential under section 632(a) if one of the parties “has an 
19   objectively reasonable expectation that the conversation is not being overheard or 
20   recorded.”  Flanagan, 
27 Cal. 4th at 777
.  “And in California, courts have developed a 
21   presumption that Internet communications do not reasonably give rise to that expectation.”  
22   Revitch v. New Moosejaw, LLC, No. 18-cv-06827-VC, 
2019 WL 5485330
, at *3 (N.D. Cal. Oct. 
23   23, 2019) (citing and collecting authorities); see also Rodriguez, 
2021 WL 2026726
, at *7 
24   (explaining that plaintiffs “must plead unique, definite circumstances” to rebut California’s 
25   presumption against online confidentiality).  The question is whether plaintiffs have shown that 
26   there is something unique about these particular internet communications which justify departing 
27   from the presumption.  For the reasons expressed below, I conclude that they have done so. 
1        Communications made in the context of a patient–medical provider relationship are readily 
2   distinguishable from online communications in general for at least two reasons.  First, patient-
3   status and medical-related communications between patients and their medical providers are 
4   protected by federal law.  See, e.g., 42 U.S.C. § 1320d-6 (providing criminal and civil penalties for 
5   disclosing protected health information without authorization); 
45 C.F.R. § 164.508
 (requiring a 
6   “valid authorization” for use or disclosure of protected health information); Section I.A.2 supra 
7   (finding that patient status is protected health information under HIPAA).  Second, unlike 
8   communications made while inquiring about items of clothing on a retail website, Revitch, 2019 
9 WL 5485330
, at *3, health-related communications with a medical provider are almost uniquely 
10   personal.  “One can think of few subject areas more personal and more likely to implicate privacy 
11   interests than that of one’s health or genetic make-up.”  Norman-Bloodsaw v. Lawrence Berkeley 
12   Lab’y, 
135 F.3d 1260
, 1269 (9th Cir. 1998); see also Doe v. City of New York, 
15 F.3d 264
, 267 
13   (2d Cir. 1994) (“Extension of the right to confidentiality to personal medical information 
14   recognizes there are few matters that are quite so personal as the status of one’s health”); cf. 
15   Facebook Consumer Priv. Litig., 402 F. Supp. 3d at 783 (“So, for example, if you are diagnosed 
16   with a medical condition, you can expect to conceal it completely only if you keep it between you 
17   and your doctor.  But it does not follow that if you send an email to selected colleagues and 
18   friends explaining why you’ll be out of commission for a while, you’ve relinquished any privacy 
19   interest in your medical condition, such that the email provider could disseminate your diagnosis 
20   to anyone who might be interested in your health status.”).  For these reasons, it seems to me that 
21   plaintiffs will likely be able to show that they had an objectively reasonable expectation that their 
22   communications with their medical providers were confidential.        
23        Accordingly, plaintiffs will likely be able to show that the communications at issue here 
24   were confidential under the CIPA.                                     
25        D.   Invasion of Privacy and Intrusion upon Seclusion Claims     
26        To prevail on these claims, plaintiffs must show that they had an objectively reasonable 
27   expectation of privacy in their medical communications and Meta’s conduct was highly offensive.   
1   Consumer Priv. Litig., 
2022 WL 2165489
, at *7 (same).                 
2        Courts are generally hesitant to decide claims of this nature at the pleading stage.  See 
3   Facebook Consumer Priv. Litig., 402 F. Supp. 3d at 797 (“Under California law, courts must be 
4   reluctant to reach a conclusion at the pleading stage about how offensive or serious the privacy 
5   intrusion is.”); Williams v. Facebook, Inc., 
384 F. Supp. 3d 1043, 1054
 (N.D. Cal. 2018) 
6   (observing that whether conduct rises to the level of highly offensive “is indeed a factual question 
7   best left for a jury”) (internal quotation marks and citation omitted); Opperman v. Path, Inc., 205 
8 F. Supp. 3d 1064, 1080
 (N.D. Cal. 2016) (“A judge should be cautious before substituting his or 
9   her judgment for that of the community.”).  At this early stage, plaintiffs’ claims appear fairly 
10   strong.   I address each element in turn.

12        I have already found that—in the context of the CIPA claim—plaintiffs will likely be able 
13   to show that they had an objectively reasonable expectation that their communications with their 
14   medical providers were confidential based on the laws and regulations protecting the 
15   confidentiality of medical information.  See Section I.C.2 supra.  Case law also supports plaintiffs’ 
16   position that individuals maintain a reasonable expectation of privacy in detailed URLs.  See In re 
17   Facebook, Inc. Internet Tracking Litig., 956 F.3d at 605–06 (finding plaintiffs adequately pleaded 
18   a reasonable expectation of privacy in “full-string detailed URLs” which contain “the name of a 
19   website, folder and sub-folders on the web-server, and the name of the precise file requested”). 
20         Meta argues that plaintiffs lacked a reasonable expectation of privacy because its policies 
21   convey that it may collect and use their personal data, including data about their browsing 
22   behavior on some third-party websites, even while users are not logged into Facebook.  But I have 
23   already found that the policies at issue did not adequately disclose that Meta collects the kind of 
24   sensitive health information at issue in this case, especially in light of the policy provision 
25   providing that Meta will “require” partners to obtain “lawful rights” to share user data before Meta 
26   will acquire it and Meta’s directives to its partners to not send any health information.  See Data 
27                                                                         
1   Policy at 5; Business Tool Terms at 2.  As a result, Meta’s policies tend to support, rather than 
2   diminish, the likelihood that a user has an objectively reasonable expectation of privacy in this 
3   specific information.  Cf. In re Facebook, Inc. Internet Tracking Litig., 
956 F.3d at 603
 (finding an 
4   objectively reasonable expectation of privacy existed where plaintiffs plausibly alleged that 
5   Facebook did not disclose that the information at issue would be collected).  
6             2.   Highly Offensive Intrusion                             
7        The next question is whether plaintiffs have shown that Meta’s intrusion was “highly 
8   offensive.”  A jury will have to weigh the injury alleged, which is potentially highly offensive, 
9   against Meta’s defense that it has developed comprehensive systems (discussed in Section III, 
10   below) to guard against the intrusion in the most effective manner practicable.  Plaintiffs have 
11   offered support for the position that Meta’s conduct is highly offensive.    
12        In determining the “offensiveness” of an invasion of a privacy interest, courts may 
13   consider: “the degree of the intrusion, the context, conduct and circumstances surrounding the 
14   intrusion as well as the intruder’s motives and objectives, the setting into which he intrudes, and 
15   the expectations of those whose privacy is invaded.”  Hill v. Nat’l Collegiate Athletic Assn., 
7 Cal. 16
   4th 1, 26 (1994) (internal citation and quotation marks omitted).  “If voluntary consent is present, 
17   a defendant’s conduct will rarely be deemed ‘highly offensive to a reasonable person’ so as to 
18   justify tort liability.”  
Id.
 (citation omitted).                     
19        There is support for plaintiffs’ position that Meta has behaved egregiously.  By enacting 
20   criminal and civil statutes forbidding the disclosure of protected health information without proper 
21   authorization, Congress has made policy decisions regarding the importance of safekeeping this 
22   information.  See, e.g., 42 U.S.C. § 1320d-6 (providing criminal and civil penalties for disclosing 
23   protected health information without authorization); 
45 C.F.R. § 164.508
 (requiring a “valid 
24   authorization” for use or disclosure of protected health information).  Courts have also found that 
25   taking personal contact information without consent could be deemed highly offensive.  See 
26   Opperman v. Path, 
87 F. Supp. 3d 1018
, 1060–61 (N.D. Cal. 2014) (finding that a jury must 
27   decide whether the “surreptitious theft of personal contact information” is highly offensive).  
1   Ninth Circuit has found to be relevant in the “highly offensive” inquiry.  See In re Facebook, Inc. 
2   Internet Tracking Litig., 
956 F.3d at 606
 (finding that highly offensive element was sufficiently 
3   pleaded where Facebook collected full-string detailed URLs and where “Plaintiffs have alleged 
4   that internal Facebook communications reveal that the company’s own officials recognized these 
5   practices as a problematic privacy issue.”).  These arguments have merit.  
6        It is true that “[c]ourts in this district have consistently refused to characterize the 
7   disclosure of common, basic digital information to third parties as serious or egregious violations 
8   of social norms.”  In re Google, Inc. Privacy Pol’y Litig., 
58 F. Supp. 3d 968, 985
 (N.D. Cal. 
9   2014).  But that is not the kind of information at issue here.  Meta does not point to a single case 
10   where a court found that the collection of the kinds of information at issue here did not constitute a 
11   highly offensive invasion of privacy.13                               
12        A preliminary injunction is an extraordinary remedy that requires the movant to carry the 
13   burden of persuasion by a “clear showing.”  Mazurek v Armstrong, 
520 U.S. 968, 972
 (1997).    It 
14   is by no means clear at this stage of the case whether plaintiffs will prevail in this litigation.  
15   Whether it is likely is a close call, and it will depend on the strength of Meta’s defense, which I 
16   discuss below in sections III and IV.                                 
17   II.  IRREPARABLE HARM                                                 
18        Plaintiffs contend that they are irreparably harmed by Meta’s ongoing interference with 
19   their right to confidential medical care and communications.14  Mot. at 19.  I agree that the harm 
20   itself is irreparable.                                                
21                                                                         

22   13 Meta’s reliance on Hammerling v. Google is misplaced.  In Hammerling, plaintiffs alleged that Google 
    violated California privacy laws by collecting personal information via various apps.  See No. 21-cv-
23   09004-CRB, 
2022 WL 2812188
, at *1 (N.D. Cal. July 18, 2022).  But the data at issue in Hammerling 
    involved “usage and engagement” data—i.e., the average number of days that users were active on 
24   particular apps and a user’s total time spent on non-Google apps.  
Id. at *1
.  Hammerling explicitly noted 
    that “the plaintiffs d[id] not allege that Google can read the specific information (i.e., content) that a user 
25                                                                         
    inputs.”  
Id. at *14
.  Because the kind of data collected in Hammerling is not analogous to the data at issue 
    here, Hammerling’s conclusion that the data disclosure was not highly offensive does not bear on the 
26                                                                         
    present matter.                                                       
27                                                                         
    14 Although Meta has implemented measures to prevent its receipt of health information, Meta 
1        The legal standard for injunctive relief requires that a plaintiff “demonstrate that 
2   irreparable injury is likely in the absence of an injunction.”  Winter, 
555 U.S. at 22
 (emphasis 
3   removed).  “Irreparable harm is traditionally defined as harm for which there is no adequate legal 
4   remedy, such as an award of damages.”  Arizona Dream Act Coal. v. Brewer, 
757 F.3d 1053
, 1068 
5   (9th Cir. 2014) (citation omitted).  “Because intangible injuries generally lack an adequate legal 
6   remedy, ‘intangible injuries [may] qualify as irreparable harm.’”  
Id.
 (quoting Rent-A-Ctr., Inc. v. 
7   Canyon Television & Appliance Rental, Inc., 
944 F.2d 597
, 603 (9th Cir. 1991)). 
8        The invasion of privacy triggered by the Pixel’s allegedly ongoing disclosure of plaintiffs’ 
9   medical information is precisely the kind of intangible injury that cannot be remedied by damages.  
10   See, e.g., Meyer v. Portfolio Recovery Assocs., LLC, 
707 F.3d 1036, 1045
 (9th Cir. 2012) (finding 
11   that violation of privacy shows irreparable harm); Brooks v. Thomson Reuters Corp., No. 21-cv-
12   01418-EMC, 
2021 WL 3621837
, at *11 (N.D. Cal. Aug. 16, 2021) (holding that injunctive relief 
13   may be available “because the injury here is an invasion of privacy that can never be fully 
14   remedied through damages” and loss of privacy is “irreparable”); Maxcrest Ltd. v. United States, 
15   No. 15-mc-80270-JST, 
2016 WL 6599463
, at *4 (N.D. Cal. Nov. 7, 2016) (“[A]ny harm to 
16   Maxcrest’s privacy interests would be irreparable because there is nothing a court can do to 
17   withdraw all knowledge or information that IRS agents may have acquired by examination of the 
18   requested information once that information has already been divulged.”) (cleaned up).  Plaintiffs’ 
19   actions underscore the seriousness of the alleged loss of privacy.  For example, plaintiff John Doe 
20   has elected to stop accessing his medical provider’s online portal, except where medically 
21   necessary or where his attorneys have counseled him to do so, in order to prevent his health data 
22   from being sent to Meta.  Declaration of John Doe (“Doe Decl.”) [Dkt. 47] ¶ 7.   
23         Meta does not challenge the severity of the harm that plaintiffs have articulated.  Instead, 
24   Meta argues that there is no irreparable harm because: (1) plaintiffs purportedly delayed in seeking 
25   injunctive relief, and (2) Meta is purportedly not causally connected to the irreparable harm.  Opp. 
26   at 11.  Those arguments are meritless.                                
27        A.  Plaintiffs Did Not Delay Before Seeking a Preliminary Injunction.  
1   injunction, which—according to Meta—undermines their claim of irreparable harm.15  Opp. at 11.  
2   A “long delay before seeking a preliminary injunction implies a lack of urgency and irreparable 
3   harm.”  Oakland Trib., Inc. v. Chron. Pub. Co., 
762 F.2d 1374
, 1377 (9th Cir. 1985) (citation 
4   omitted); see also Garcia, 
786 F.3d at 746
 (waiting “months to seek an injunction . . . undercut[s] 
5   Garcia’s claim of irreparable harm”).  But “delay is only one factor among the many that we 
6   consider in evaluating whether a plaintiff is likely to suffer irreparable harm absent interim relief.”  
7   Cuviello v. City of Vallejo, 
944 F.3d 816, 833
 (9th Cir. 2019).       
8        The two month period at issue here is readily distinguishable from the situations where 
9   courts have found that a delay in seeking an injunction weighs against irreparable harm.  In 
10   Oakland Tribune, for instance, the Ninth Circuit affirmed the denial of a preliminary injunction 
11   where “the exclusivity provisions which plaintiff seeks to enjoin have been in effect for a number 
12   of years.”  762 F.2d at 1377.  And in Garcia, the plaintiff moved for a preliminary injunction 
13   approximately four months after the film (which formed the basis for her copyright claim) was 
14   posted on the internet.  786 F.3d at 737–38.  In addition to the cases cited by Meta, other Ninth 
15   Circuit decisions suggest that waiting two months before seeking an injunction does not lessen a 
16   claim of irreparable harm.  See Arc of California v. Douglas, 
757 F.3d 975, 990
 (9th Cir. 2014) 
17   (challenging a law which “was passed only months before the initiation of this lawsuit” weighed 
18   against finding delay); cf. Cuviello, 
944 F.3d at 822, 834
 (finding that plaintiff delayed by seeking 
19   preliminary injunction almost two years after learning of restraint on speech but that plaintiff had 
20   still shown irreparable harm); Lydo Enterprises, Inc. v. City of Las Vegas, 
745 F.2d 1211
, 1213–14  
21   (9th Cir. 1984) (finding that a five year delay before “taking any action” weighed against finding 
22   of irreparable harm).                                                 
23        The issues in this case are factually, technologically, and legally complex.  The two month 
24   period between the complaint and the motion for a preliminary injunction does not undermine 
25   plaintiffs’ showing of irreparable injury.                            
26                                                                         
27                                                                         
         B.   Plaintiffs Allege Irreparable Harm Causally Connected to Meta’s Conduct.  
1                                                                         
         Meta also contends that there is no irreparable harm because “plaintiffs have not shown 
2                                                                         
    that their alleged harm is caused by the defendant.”  Opp. at 12.  It claims that it is not responsible 
3                                                                         
    because (1) plaintiffs can purportedly avoid injury by disconnecting their off-Facebook activity, 
4                                                                         
    and (2) third party website developers, not Meta, are to blame.  
Id.
  Neither argument defeats

    activity from their accounts, which they can do—according to Meta’s senior software engineer—

    Decl. ¶ 11 (explaining that Meta users can control or disconnect their off-Facebook activity).  Its 
10                                                                         
    misunderstanding of plaintiffs’ claim is laid bare with this statement from its opposition brief: 
11                                                                         
    “Meta gives users the ability to control the use of information about their off-Facebook activity 
12                                                                         
    (such as activity on third-party websites) for advertising purposes.”  Opp. at 6 (emphasis added).   
13                                                                         
         Plaintiffs do not merely object to receiving targeted advertising based on their health 
14                                                                         
    information.  The heart of plaintiffs’ complaint—and the core injury asserted therein—is that Meta 
15                                                                         
    is accessing their health information in violation of state and federal law.  During the hearing, 
16                                                                         
    Meta conceded that it does not enable Facebook users to prevent Meta from accessing their 
17                                                                         
    information.  See PI Hrg. Tr. at 7:23–8:23.  Because Meta does not enable plaintiffs to “opt out” of 
18                                                                         
    using the Pixel, Meta’s argument and authorities regarding “self-inflicted” harm are irrelevant.     
19                                                                         
         Meta’s other argument hinges on the premise that Meta cannot stop website developers 
20                                                                         
    from sending it health information.  Opp. at 12–13.  But Meta conceded that it “has the ability to 
21                                                                         
    block all data coming in from a specific website or specific Pixel ID,” which Meta has done in 
22                                                                         
    certain circumstances.  See Supp. Wooldridge Decl. ¶ 51 (emphasis in original).  Putting aside the 
23                                                                         
    appropriateness of such a measure, which is discussed in the balance of the equities section below, 
24                                                                         
    the fact stands that Meta is capable of turning the Pixel off for certain websites.  Plaintiffs have 
25                                                                         
    alleged that Meta is causally connected to their injury.  That website developers may also be liable 
26                                                                         
    does not mean, of course, that Meta is exempt from liability.  And Meta’s efforts to prevent receipt 
27                                                                         
    of health information do not diminish the irreparable invasion of privacy that plaintiffs have 
1   experienced.

.  For the reasons set forth below, I find that 
7   plaintiffs have not done so.                                          
8        As noted above, plaintiffs describe a weighty injury.  Privacy is “a most fundamental 
9   human right” that is “older than the Bill of Rights[.]”  See Kewanee Oil Co. v. Bicron Corp., 416 
10 U.S. 470
, 487 (1974); Griswold v. Connecticut, 
381 U.S. 479, 486
 (1965).  And while privacy is 
11   important, it is also fragile: with a mere click of the mouse, one’s personal information may be 
12   disseminated to the world.  There is no way to undo a loss of privacy.   
13        Without minimizing the gravity of plaintiffs’ injury, though, two points merit caution.  
14   First, Meta contends that plaintiffs’ recommendations for how Meta could modify its existing 
15   filtration systems to comply with an injunction are either already implemented or are infeasible in 
16   light of Meta’s existing systems.  See Supp. Wooldridge Decl. ¶¶ 16, 23–26, 31, 33–39.  The 
17   Supp. Wooldridge Decl. describes the resources16 that Meta has already invested in its filtration 
18   systems and contextualizes the technological issues implicated by an injunction of the sort that 
19   plaintiffs seek.  Id. ¶ 46.  Wooldridge explained that Meta designed its existing filtering 
20   mechanism to detect and filter out potentially sensitive data transmitted via the Pixel in light of the 
21   vast quantity of data that floods Meta every day.  Id. ¶ 8.  According to Meta, Meta’s existing 
22   filtration systems are “the most effective and feasible methods” for Meta to detect and prevent the 
23   receipt of potentially sensitive information at scale.  Id. ¶ 47.  At this point, I have no reason not to 
24   credit Meta’s assertions regarding the design of the filtration systems or the feasibility of Wilson’s 
25                                                                         

26                                                                         
    16 There are currently 15 Meta employees (including four dedicated engineers) working on improving the 
27   integrity systems used to detect and filter out potentially sensitive health data sent via the Meta Pixel, and 
    80 employees who are involved in other aspects of Meta’s filtration systems.  Supp. Wooldridge Decl. 
1   recommendations.                                                      
2        Second, at this early stage of litigation, many of the facts are unknown or still developing.  
3   It is not clear to me, for instance, how many hospital systems currently use the Pixel on their 
4   patient portals.17  Nor do I know how successfully Meta’s filtration systems flag and block the 
5   health information at issue in this case.  Plaintiffs claim that the filtration systems are 
6   “ineffective,” see Reply at 6 n.4, but without the benefit of discovery, plaintiffs must rely on 
7   anecdotal evidence from their expert.  See Smith Decl. ¶¶ 187–90.  And while Wilson described 
8   steps that Meta purportedly already has available to comply with an injunction based on the filings 
9   from this case so far, Meta’s senior software engineer contends that these steps are infeasible in 
10   light of how Meta’s systems actually function.  See Supp. Wooldridge Decl. ¶¶ 16, 23–26, 31, 33–
11   39.  All this is to say: plaintiffs have described what is potentially a serious problem.  But at this 
12   point, the precise contours of this problem—the number of HIPAA-entities currently sending 
13   patient information to Meta, the amount of data that seeps through the filtration systems, and the 
14   feasibility of other technological solutions—remain unknown.          
15        Discovery will eliminate some of these unknowns.  Once plaintiffs learn more about 
16   Meta’s filtration systems and develop an understanding of the kinds of data that are or are not 
17   blocked, plaintiffs will be on stronger footing regarding both the feasibility and necessity of 
18   technological changes.  Should plaintiffs learn that Meta’s filtration system is indeed ineffective or 
19   that Meta can readily refine its systems to block the patient information at issue here, the balance 
20   of equities may at that point tilt in favor of an injunction.  In the meantime, I expect Meta to 
21   continue to refine its filtration systems to address the issues raised by this case.18   
22        The record is not sufficiently developed at this stage to make a judgment regarding the 
23                                                                         

24                                                                         
    17 Plaintiffs allege that they “have identified at least 664 hospital systems or medical provider web 
25   properties where Facebook has received patient data via the Facebook Pixel.”  FAC ¶ 15.  But the extent to 
    which these entities currently use the Pixel is unclear.  Smith observed that after plaintiffs had filed suit, the 
26   Pixel was removed “from a number of” hospital websites.  Smith Decl. ¶¶ 192–97.  And Meta contends that 
    the three hospital systems used by plaintiffs do not currently feature the Pixel on the patient portal 
27   webpage.  See Supp. Wooldridge Decl. ¶¶ 3–6.                          
1   equities in this case.  I suspect it will be clearer after discovery. 
2   IV.   PUBLIC INTEREST                                                 
3        The balance of equities focuses on the parties, but “the public interest inquiry primarily 
4   addresses impact on non-parties rather than parties,” and takes into consideration “the public 
5   consequences in employing the extraordinary remedy of injunction.”  hiQ Labs, Inc. v. LinkedIn 
6   Corp., 
31 F.4th 1180, 1202
 (9th Cir. 2022) (quoting Bernhardt v. Los Angeles Cnty., 
339 F.3d 7 920
, 931–32 (9th Cir. 2003)).  For the reasons set forth in the preceding section, I find that the 
8   public interest factor does not—at this point—favor an injunction.    
9        To be sure, the public has an interest in privacy in general and health information in 
10   particular.  But I must also consider the “public consequences” of imposing injunctive relief under 
11   these circumstances.  See hiQ Labs., 
31 F.4th at 1202
.  Although key information remains 
12   unknown, plaintiffs ask me to impose a mandatory injunction against a company that has already 
13   gone to some lengths to address these issues.  Putting the efficacy of Meta’s filtering system to the 
14   side, the fact remains that Meta has designed and implemented the systems which it believes are 
15   the “most effective and feasible methods” to address the receipt of sensitive information.  Supp. 
16   Wooldridge Decl. ¶ 47.  Against this backdrop, I am not convinced that the public interest would 
17   support imposing an injunction against companies in Meta’s position.  
18        In light of the systems in place that Meta has created to block receipt of this sensitive 
19   information and the factual uncertainties described above, it is too early to find that the public 
20   interest supports a mandatory injunction.  Of course, my perspective may evolve as the factual 
21   record develops in the case.                                          
22                              CONCLUSION                                 
23        My analysis of the Winter factors shows that neither the equities nor the public interest 
24   currently supports an injunction.   Although plaintiffs have potentially strong arguments on both 
25   the merits and irreparable injury, they cannot meet the high standard required for a mandatory 
26
