Twitch Interactive, Inc. has launched a new proceeding at the Patent Trial and Appeal Board, filing inter partes review petition IPR2026-00397 on June 29, 2026. For patent litigators and in-house IP teams, the case is worth watching both for what it may reveal about Twitch’s broader patent risk strategy and for how the Board approaches the prior art and validity issues raised in the petition.

At this early stage, the PTAB docket reflects the filing of the petition, but practitioners will want to monitor the record closely for the patent owner’s preliminary response, the Board’s institution decision, and any related district court litigation that may shape the parties’ positions.

A new inter partes review has been filed at the Patent Trial and Appeal Board against ResMed Corp., opening another front in the increasingly important fight over respiratory and sleep-therapy technology. The petition, docketed as IPR2026-00341 and filed June 12, 2026, places at issue the validity of a ResMed patent before the PTAB, where petitioners can seek cancellation of issued patent claims based on prior art patents and printed publications.

At this early stage, the publicly available docket information identifies the proceeding as Resmed Corp., but does not yet provide the full set of petition details typically most relevant to practitioners, including the patent number, the petitioner’s identity, and the specific prior-art combinations asserted.

Meta Platforms, Inc. has launched a new inter partes review at the Patent Trial and Appeal Board, filing IPR2026-00347 on May 13, 2026. At this stage, the PTAB docket reflects the petition filing, but practitioners should note that early-filed IPRs like this one often become important indicators of broader litigation and licensing strategy, especially when a major technology company is the petitioner.

The proceeding is styled Meta Platforms, Inc., identifying Meta as the challenging party.

A new inter partes review, IPR2026-00343, was filed at the Patent Trial and Appeal Board on April 24, 2026, naming Skechers U.S.A., Inc. in the proceeding.

Samsung Electronics Co., Ltd. has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening IPR2026-00337 on April 15, 2026. The proceeding places another potentially significant patent dispute on the PTAB’s docket and gives patent practitioners an early look at what may become an important validity fight involving Samsung as petitioner.

At this stage, the publicly available case caption identifies Samsung Electronics Co., Ltd. as the petitioner, but practitioners should watch the docket closely for the patent owner’s formal identification, the challenged patent number, and the specific claims at issue as those details become more fully reflected in the record.

In IPR2025-01188, the Patent Trial and Appeal Board terminated the proceeding after the parties settled following institution. The decision applies the familiar framework of 35 U.S.C. § 317 and 37 C.F.R. § 42.74, which govern settlement and termination of inter partes review, but it is still a useful reminder of how the Board handles cases once trial is already underway.

The core ruling is straightforward: when the parties jointly request termination after institution and the Board has not yet decided the merits, the PTAB generally will terminate the review as to those parties.

A newly filed opposition in IPR2025-00677 puts a familiar but strategically important PTAB issue front and center: whether a patent owner’s proposed substitute claims can survive scrutiny when offered through a contingent motion to amend. In its April 7, 2026 filing, the petitioner asks the Patent Trial and Appeal Board to deny the patent owner’s amendment request, arguing that the revised claims still do not satisfy the governing patentability and procedural standards.

A contingent motion to amend is exactly what it sounds like: the patent owner proposes substitute claims only if the Board finds the original claims unpatentable.

In a short but useful procedural order, the Patent Trial and Appeal Board granted the patent owner’s unopposed motion to withdraw existing lead counsel and substitute new lead counsel in PGR2025-00086. The order applies 37 C.F.R. § 42.10, the PTAB rule governing counsel recognition and changes in representation, and reflects the Board’s routine but important emphasis on continuity of representation.

Although the ruling does not break new doctrinal ground, it is a practical reminder that PTAB counsel changes are not automatic.

Toyota Motor Corporation has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening proceeding IPR2026-00333 on April 7, 2026. The filing places at issue the validity of a patent that, while not identified in the docket caption itself, is now the subject of a formal PTAB challenge by one of the world’s largest automotive companies. For patent owners and accused infringers alike, that alone makes this proceeding worth watching closely.

At this stage, the key public-facing details are the petitioner, the forum, and the timing.
