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.

A new petition at the Patent Trial and Appeal Board, IPR2026-00413, was filed on August 14, 2026, and names Luxottica of America Inc. in the proceeding caption. For patent practitioners tracking activity in the eyewear, retail, consumer products, or branded technology spaces, this is a matter worth watching as the record develops.

At this early stage, the publicly available docket information identifies the proceeding title, filing date, and PTAB docket number, but key details that practitioners will want—most notably the patent number being challenged, the full party alignment between petitioner and patent owner, and the specific invalidity grounds asserted under 35 U.S.C. §§ 102 and/or 103—will likely become clearer as the petition and accompanying papers are added to the docket.

That said, the filing itself is significant.

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.

Google LLC has filed a new inter partes review petition at the Patent Trial and Appeal Board in IPR2026-00429, opening another closely watched front in the company’s broader patent defense strategy. The proceeding, filed on July 29, 2026, is captioned simply Google LLC, but as with any PTAB matter, the key questions for patent practitioners will be which patent claims are under attack, what prior art combinations are being asserted, and whether the Board views the petition as a strong candidate for institution.

At this early stage, the docket signals the beginning of the challenge rather than its resolution.

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.

A new inter partes review, IPR2026-00448, was filed on July 29, 2026, at the Patent Trial and Appeal Board and is captioned Dolby Laboratories, Inc. For patent litigators and in-house IP teams, the filing is worth watching not only because Dolby is a well-known player in audio and media technology, but also because PTAB challenges involving established portfolio owners often carry broader implications for parallel district court strategy, licensing leverage, and portfolio durability.

At this early stage, the public caption identifies the proceeding by the patent owner name, but the currently available case details do not yet specify in the docket summary which particular patent claims are being challenged, who the petitioner is, or the precise statutory grounds asserted.

At this early stage, the key public takeaway is that a major footwear company has turned to the PTAB to test the validity of a patent that is important enough to warrant administrative review.

The Patent Trial and Appeal Board’s Final Written Decision in IPR2025-00565 offers another useful look at how the Board is evaluating invalidity challenges at the merits stage—and what practitioners must do to carry their burdens through trial. Although the case turns on the particular patent claims and prior-art record presented, the decision underscores several recurring themes in PTAB practice: precise claim construction, disciplined obviousness analysis, and careful attention to evidentiary support.

In a final written decision, the Board resolves whether the petitioner has shown, by a preponderance of the evidence, that the challenged claims are unpatentable.

A new inter partes review, IPR2026-00434, was filed on July 23, 2026, at the Patent Trial and Appeal Board and is styled Aces Fuel Injection, Inc.. While the docket caption presently highlights the patent owner, the proceeding signals the start of what could become an important validity fight over fuel-injection technology and related patent claims.
