A new post-grant review, PGR2027-00004, was filed at the Patent Trial and Appeal Board on October 10, 2026, naming Shenzhen Torras Technology Co., Ltd. in the proceeding. For patent litigators, portfolio managers, and in-house IP counsel, this is the kind of early-stage PTAB matter worth watching closely—particularly because post-grant review can put a broad range of patentability issues in play well beyond the prior-art combinations typically seen in inter partes review.

At this stage, the docket identifies the proceeding by title but does not, from the case caption alone, reveal the full patent number, the petitioner’s identity, or the specific claims challenged.

Luxottica of America Inc. has filed a new inter partes review, IPR2026-00512, at the Patent Trial and Appeal Board on September 29, 2026. At this early stage, the filing itself is the key development: it signals that Luxottica is turning to the PTAB to challenge the validity of an asserted patent rather than limiting the fight to district court litigation or licensing negotiations.

Based on the docket caption, Luxottica of America Inc. is the petitioner.

Salesforce, Inc. has launched a new inter partes review at the Patent Trial and Appeal Board, filing IPR2026-00477 on September 24, 2026. Although the public docket caption identifies the petitioner as Salesforce, the filing is notable for what it may reveal about the company’s broader patent defense strategy and the kinds of prior-art arguments now being tested at the PTAB.

At this stage, the basic procedural posture is clear: Salesforce is asking the Board to review the validity of an issued U.S. patent through the IPR process, which allows petitioners to challenge patent claims on anticipation and obviousness grounds based on patents and printed publications.

Netskope, Inc. has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening PTAB docket IPR2026-00474 on September 15, 2026. For patent litigators and in-house IP teams, this is the kind of proceeding worth monitoring early: even at the filing stage, an IPR can signal a broader enforcement dispute, a defensive campaign against a competitor’s portfolio, or a strategic effort to reshape parallel district court litigation.

At this stage, the publicly available docket information identifies Netskope, Inc. as the petitioner, but the full petition and accompanying papers will be critical to pin down the complete picture — including the specific patent being challenged, the patent owner, and the precise prior-art grounds asserted.

Amazon.com Services LLC has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening IPR2026-00471 on September 11, 2026.

Amazon.com Services LLC has filed a new inter partes review petition at the Patent Trial and Appeal Board, opening IPR2026-00471 on September 11, 2026. At this early stage, the PTAB docket indicates that Amazon is the petitioner, but practitioners will want to monitor the record closely for the identity of the patent owner, the specific patent number being challenged, and the prior-art combinations asserted in the petition as those details become available on the docket.

An IPR filing alone can be strategically significant.

At this stage, the public docket identifies the petitioner as Apple Inc., but practitioners will want to watch closely for the petition and accompanying exhibits to clarify the specific patent being challenged, the real party-in-interest disclosures, and the precise prior-art combinations Apple is advancing.

Even from the opening docket information, this proceeding is worth tracking.

Meta Platforms, Inc. has launched a new inter partes review proceeding at the Patent Trial and Appeal Board, filing IPR2026-00459 on August 26, 2026. The petition adds to the steady stream of technology-company PTAB activity that in-house IP teams and patent litigators monitor closely for signals on validity strategy, parallel district court risk, and the Board’s treatment of software-focused claims.

At this stage, the docket reflects Meta as the petitioner, but practitioners should note that early PTAB filings often require close review to identify the full scope of the challenge: the specific patent owner, the patent number at issue, the challenged claims, and whether the petition is tied to co-pending litigation or broader portfolio pressure.

Apple Inc. has launched a new challenge at the Patent Trial and Appeal Board, filing inter partes review petition IPR2026-00438 on August 17, 2026. At this early stage, the docket signals the opening of another high-stakes PTAB contest involving one of the most active technology companies in the patent arena. For practitioners tracking repeat PTAB filers, portfolio pressure campaigns, or parallel district court strategy, this is a proceeding worth watching.

The petitioner is Apple Inc.. Based on the currently available case information, Apple is seeking PTAB review of an issued patent, with the patent owner and the specific patent number expected to become clearer as the petition and related filings are further reflected on the docket.

Luxottica of America Inc. has filed a new inter partes review proceeding at the Patent Trial and Appeal Board, opening another matter for practitioners tracking how major consumer-brand companies use PTAB challenges as part of broader patent defense strategy. The petition, docketed as IPR2026-00412 and filed on August 7, 2026, is now pending before the Board.

At this early stage, the PTAB docket entry identifies Luxottica of America Inc. in the case caption, but the publicly available case summary does not yet provide the full set of details practitioners will want to monitor closely, including the challenged patent number, the named patent owner, and the specific prior-art grounds asserted in the petition.

A new inter partes review, IPR2026-00408, was filed at the Patent Trial and Appeal Board on July 28, 2026, under the caption Zhuhai CosMX Battery Co., Ltd. For patent practitioners tracking battery-sector disputes and PTAB filing trends, this is a proceeding worth watching as the record develops.

At this early stage, the publicly available docket information identifies the petitioner as Zhuhai CosMX Battery Co., Ltd., but the initial case caption alone does not yet provide the full picture of the challenged patent, the patent owner, or the specific prior-art combinations being asserted.

Zoom Communications, Inc. has launched a new challenge at the Patent Trial and Appeal Board, filing inter partes review petition IPR2026-00424 on July 24, 2026. For patent litigators and in-house IP teams, the case is worth watching both for what it may reveal about Zoom’s defensive patent strategy and for how the Board addresses the prior-art arguments once the petition and supporting papers are fully joined on the docket.

At this stage, the publicly available case caption identifies Zoom Communications, Inc. as the petitioner, but practitioners should review the underlying filings to confirm the patent owner, the specific U.S. patent number being challenged, and the claims at issue. Those details typically frame the entire dispute: whether the challenged patent covers core communications, conferencing, networking, or collaboration functionality, and whether the petition is aimed at neutralizing litigation exposure, licensing pressure, or competitive risk.

As with any IPR, the key battleground will be the grounds for review. PTAB petitions commonly rely on anticipation or obviousness theories under 35 U.S.C. §§ 102 and 103, built from combinations of patents, printed publications, and expert declarations.
