A new post-grant review, PGR2026-00072, has been filed at the Patent Trial and Appeal Board involving Anagen LLC. The petition was filed on September 1, 2026, opening what could become an important proceeding for patent owners, challengers, and counsel tracking how recently issued patents are tested at the PTAB.

At this stage, the docket information publicly identifies the matter by the title Anagen LLC, but practitioners should note that early PTAB dockets do not always immediately reveal the full contours of the dispute from the caption alone.

Meta Platforms, Inc. has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening IPR2026-00347 on May 13, 2026. At this early stage, the PTAB docket reflects the filing of the petition, but practitioners should expect the key details—most importantly the specific patent being challenged, the patent owner’s identity, and the precise prior-art combinations—to come into sharper focus as the docket develops.

Even from the initial filing, this is a proceeding worth watching.
