Aaron J. Moss

Chair, Litigation Department
Fax 310-201-2314


Aaron Moss represents owners and users of creative content, and has been recognized by virtually every major legal and entertainment business publication as one of the preeminent intellectual property litigators in his field.

Aaron is chair of Greenberg Glusker's Litigation Department, co-chair of the Coronavirus Task Force, and a member of its Intellectual Property Department. 

He has been named to The Hollywood Reporter’s “Top 100 Power Lawyers” list, Variety’s “Legal Impact Report,” the Daily Journal’s "Top Intellectual Property Lawyers," and was named among the city’s top IP attorneys in the Los Angeles Business Journal’s list of “40 Angelenos to Know in Intellectual Property Law.”

Aaron litigates high-profile copyright and trademark actions for both plaintiffs and defendants, including studios, independent distributors, production companies, video game publishers, toy companies, apparel manufacturers, technology firms and individuals. He has particularly extensive experience handling matters involving the ownership, licensing and termination of rights in fictional characters, including such globally-recognized properties as Godzilla, Spider-Man, Lassie, Frosty the Snowman, and Casper the Friendly Ghost.

Aaron also provides advice and counsel in connection with intellectual property acquisitions and transfers, conducts complex chain of title analyses, and engages in pre-publication clearance reviews for authors, publishers, filmmakers, and video game companies – often enabling them to avoid costly lawsuits.

In addition to his copyright and trademark practices, Aaron has litigated high-stakes profit participation cases, prosecuted and defended idea submission claims, and has represented award-winning actors and performers in right of publicity actions involving the unauthorized use of their names, voices and likenesses. He also handles defamation, invasion of privacy and other media-related disputes, as well as cybersquatting, false advertising, unfair competition and breach of contract actions across a wide range of industries.
