The parties and the patent

The proceeding is Twitch Interactive, Inc. v. CP Studios LLC, IPR2026-00514. Twitch Interactive, Inc. is the petitioner. The petition names Twitch Interactive, Inc., Amazon.com Services LLC and Amazon.com, Inc. as the real parties in interest, and CP Studios LLC as the patent owner. U.S. Patent 9,889,373 is titled Multilayer Framework and Architecture with Variable Video Gaming Capabilities.

What the claims cover

Claim 1 covers a computer-implemented method for implementing a multilayer architecture for video gaming. A server hosts a video gaming environment, gives a plurality of user devices access to it, and designates each user a status level, each level providing a different capability: a first player status level with full access and play, a second with restricted access and play, and a third with reactive access and play. Under the reactive access, a keyword response that a third-level user comments on a social network post of a first-level or second-level user affects elements of gameplay. Claim 8 is a parallel system claim, and the remaining twelve claims depend from claims 1 and 8.

The Delaware cases

CP Studios sued Twitch in the District of Delaware on December 19, 2025, in CP Studios, LLC v. Twitch Interactive, Inc., No. 1:25-cv-01542, asserting the '373 patent together with U.S. Patents 9,604,132, 10,632,388 and 11,731,054. The complaint accuses Twitch's live streaming platform, including Twitch.tv, the Twitch Mobile App and Twitch Studio, through interactive features that it says allow viewers to affect gameplay. It alleges, on information and belief, that Twitch directly infringes claim 1 of the '373 patent, and it seeks damages, a finding of willful infringement and treble damages. On May 18, 2026, CP Studios filed a second Delaware case against Twitch, No. 1:26-cv-00571, and that docket's report to the USPTO lists the same four patents. Judge Maryellen Noreika is assigned to both cases.

The grounds

The petition raises four obviousness grounds under 35 U.S.C. 103, and each ground challenges claims 1 to 14: (1) Barclay '019, U.S. Patent 8,671,019, renders claims 1 to 14 obvious; (2) Barclay '019 and Barclay '363, U.S. Patent Application Publication 2012/0184363, render claims 1 to 14 obvious; (3) FarmVille, the 2011 book FarmVille For Dummies, and Tweet Land, an archived 2011 web article about the Tweet Land Kickstarter game project, render claims 1 to 14 obvious; and (4) FarmVille, Tweet Land, and a Zynga patent, U.S. Patent 8,790,182, render claims 1 to 14 obvious. The petition relies on a technical expert's declaration.
