Lanham Act Rule of Law: Under AMF Inc. v. Sleekcraft Boats, 599 F.2d 341 (9th Cir. 1979) and Rogers v. Grimaldi, 875 F.2d 994 (2d Cir. 1989), expressive titles receive First Amendment protection preventing Lanham Act liability unless the title has no artistic relevance to the underlying work whatsoever, or explicitly misleads consumers regarding the source or content of the work.

Jurisprudential Framework: Entertainment Titles & Trademark Doctrines

How federal courts balance commercial trademark rights against creative expression under Article III and the First Amendment.

Reverse Confusion Mechanics

In reverse confusion (e.g., Dreamwerks Production Group v. SKG Studio), a junior user with massive market power saturates the market with a similar mark. Consumers mistakenly believe the senior, smaller mark holder is actually an unauthorized copycat or subsidiary of the giant defendant.

Senior Mark Strength: Assessed in commercial niche, but junior marketing blitz proves saturation.
Injury: Loss of independent identity, goodwill, and freedom to expand products.

The Rogers v. Grimaldi Test

Federal courts apply the heightened Rogers test to creative works (movies, books, albums, series titles) before applying traditional 8-factor likelihood-of-confusion tests:

Prong 1 (Artistic Relevance): The threshold is low ("above zero"). If the title bears any relationship to the characters or theme, it passes.
Prong 2 (Explicit Misleadingness): Requires affirmative misrepresentation of source (e.g., "Authorized by Demon Hunter"). Merely using similar words is insufficient.

Jack Daniel's (2023) Limits

In Jack Daniel's Properties, Inc. v. VIP Products LLC (599 U.S. 140), the Supreme Court clarified that the Rogers test does not apply when the accused infringer uses a mark as a designation of source for its own goods (e.g., brand tags on chew toys or retail shirts).

Expressive title use on a Netflix series = Rogers applies.
Standalone trademark use on general merchandise = Traditional Sleekcraft factor scrutiny.
