This guide sets the marking and notice regimes for every major category of U.S. intellectual property side by side so that a business owner, a litigator, and a judge can each follow the same analysis. It walks through patent marking under 35 U.S.C. § 287 (constructive notice, the "substantially all" rule, actual notice, virtual marking, licensee compliance, and design patents), the false-marking prohibition of § 292 after Forest Group v. Bon Tool and the America Invents Act, federal trademark and trade dress registration notice under 15 U.S.C. § 1111, the effect-free but strategically valuable TM and SM symbols, and copyright notice under 17 U.S.C. §§ 401–402 after the Berne Convention. It explains how each regime governs a rights holder's access to damages and profits, what happens when a product carries several rights at once, and how the three logics differ. The article then fuses everything into a single coordinated compliance program and a fully worked hypothetical, with primary and secondary authority cited throughout.
