How later courts describe this case

  • holding that Federal Circuit law governs the relevance of discovery requests in patent cases when substantive patent law is implicated
  • concluding that “[i]n assessing the burden of complying with a subpoena, a court may consider as one factor that the deponent is not a party.”
  • stating that the determination of relevance under Federal Rule of Civil Procedure 26(b)(1), which “implicates the substantive law of patent validity and infringement,” is governed by Federal Circuit law
  • “That evidence is ‘secondary’ in time does not mean that it is secondary in importance.”
  • “[A] determination of relevance implicates the substantive law of patent validity and infringement. Hence, we look to Federal Circuit law.”
  • ‘The normal and expected reluctance of business firms to disclose sales information ... is in itself an insufficient basis on which to deny discovery of that information under appropriate protection from divulgement to competitors.”
  • "If tile district court on reconsideration remains of tire view that an order to quash is appropriate, it must provide an articulation of reasons why disclosure of the sales information sought under a suitable protective order would be unreasonable and oppressive.”
