Full Claim Scope Must Be Enabled To Avoid Invalidity
Client Alert | 1 min read | 02.05.08
In Sitrick v. Dreamworks, LLC, (No. 07-1174, February 1, 2008), a Federal Circuit panel affirms a district court’s judgment of invalidity for lack of enablement. The claims at issue are directed to integrating user generated audio or visual content into a pre-existing video game or movie by “selectively substitut[ing] user image data for predefined character image data so as to provide an audiovisual presentation that includes the [user provided] image integrated therein.” The accused product allows users to combine their own voice with pre-existing video images stored on a DVD.
Citing to Auto. Techs. Int’l, Inc. v. BMW of N. Am., Inc., 501 F.3d 1274 (Fed. Cir. 2007), the panel reasons that, because the asserted claims are broad enough to cover both movies and video games, the patent disclosure must enable both embodiments. According to the panel opinion, a “patentee who chooses broad claim language must make sure the broad claims are fully enabled.” The asserted claims are not deemed to be enabled in the context of movies because, unlike video games, movies do not rely on discrete address and control signals. In support of its conclusion, the Federal Circuit panel also notes the undisputed evidence showing that it is difficult, if not impossible, to isolate any one voice from the rest of the sounds in movie soundtracks.

California Considering A Massive Expansion of Its Antitrust Laws
Legislative efforts to significantly expand California’s antitrust laws are working their way through the state legislature. The most comprehensive overhaul is Assembly Bill 1776 — the Competition and Opportunity in Markets for a Prosperous, Equitable and Transparent Economy (COMPETE) Act, introduced by Assembly Majority Leader Cecilia Aguiar-Curry, on March 23, 2026. AB 1776 is modeled closely after draft legislation recommended by the California Law Revision Commission (CLRC) in December. AB 1776 would not only significantly expand potential liability for single-firm conduct and monopolization but would also explicitly decouple California antitrust analysis from certain federal standards. Companies doing business in California should pay close attention to AB 1776 because of its potentially dramatic impact, including increased exposure to antitrust litigation and increased compliance costs.
