PTAB challenges

The previous search results for IPR2026-00067 provided the status "Pending - Instituted" and identified the patent owner as MYW Semitech LLC and the petitioners as [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) and Taiwan Semiconductor Manufacturing Co Ltd.. However, they did not provide the specific institution date, the judge panel, or the detailed grounds (claims challenged, specific prior art, statutory basis). The other search results provided general information about PTAB decisions or other IPR cases.

I need to find the institution decision document for IPR2026-00067 to get these details. Given the "Trial Instituted" status and "last modified 2026-05-22" from the prompt, the institution decision should be available.

Let's try a more direct search on the USPTO PTAB E2E portal or try to find a news article specifically about the institution of IPR2026-00067.

   There is currently one AIA trial proceeding on file for US patent 11894306, which is active and in the trial instituted phase. This means that the patent owner, Myw Semitech LLC, is currently defending the patentability of its claims against a challenge, and no claims have been invalidated or sustained by a final written decision yet.

IPR2026-00067 — Taiwan Semiconductor Manufacturing Company Ltd. et al. v. Myw Semitech LLC

• Type: Inter Partes Review
• Filed: 2025-11-21
• Status: Trial Instituted. The Patent Trial and Appeal Board (PTAB) has determined there is a reasonable likelihood that the petitioner would prevail on at least one challenged claim, and the trial phase has commenced. The last modification to this proceeding was on 2026-05-22.
• Judge panel: The specific judge panel assigned to the trial for IPR2026-00067 is not publicly available through the provided search results. However, under the new USPTO policy effective October 20, 2025, the Director of the USPTO, John A. Squires, is responsible for deciding whether to institute IPR trials.
• Petition grounds: The specific claims challenged, the prior art references, and the statutory basis (§ 102 for anticipation or § 103 for obviousness) for the petition are not explicitly detailed in the publicly available search results.
• Institution decision: The proceeding was instituted. While a "Notice of Decisions on Institution" from Director Squires dated May 6, 2026, was found, IPR2026-00067 was not explicitly listed in the 'granted' section of that particular notice. However, the canonical "PTAB proceedings on file" and Unified Patents data confirm its "Trial Instituted" status, suggesting a decision was made around the 6-month mark from filing (circa 2026-05-21), consistent with the "last modified 2026-05-22" date. The reasoning for institution is not detailed in publicly accessible summaries without the full decision document.
• Final Written Decision (if issued): Not yet issued. The PTAB has a statutory deadline to issue a final written decision within one year of institution. Based on an estimated institution date around May 21, 2026, the Final Written Decision would be due around May 21, 2027.
• Settlement / termination: Not applicable, as the proceeding is active.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This proceeding is currently active, with the patent claims under review for patentability. Until a Final Written Decision is issued, all claims of US11894306 remain presumptively valid. A defendant facing assertion of this patent should closely monitor the outcome of this IPR, as any invalidated claims would significantly impact the patent owner's enforcement strategy.

Strategic summary

All claims of US11894306 are currently UNTESTED by a Final Written Decision in an AIA trial. The sole IPR proceeding, IPR2026-00067, is in the "Trial Instituted" phase, meaning the PTAB found a reasonable likelihood of unpatentability for at least some challenged claims, but no final determination has been made.

The estoppel landscape under § 315(e)(2) is not yet applicable, as there has been no Final Written Decision. Therefore, the petitioners (Taiwan Semiconductor Manufacturing Company Ltd. and Apple Inc.) are not yet barred from asserting grounds that were raised or reasonably could have been raised in this IPR. For a potential defendant, this means that most prior-art grounds remain theoretically available for future challenges, subject to their own diligence and timing.

A clear pattern signal is the joint petition by Apple Inc. and Taiwan Semiconductor Manufacturing Company Ltd. Unified Patents data indicates that Apple Inc. has been an active petitioner in numerous IPRs, often alongside other companies. The fact that these petitioners have joined forces to challenge US11894306, and potentially other patents owned by Myw Semitech LLC (IPR2026-00065, IPR2026-00066 are also listed as instituted and involve the same parties), suggests a concerted and aggressive strategy to invalidate related patents, likely in response to broader litigation.

Recommended next steps

For a defendant currently being asserted against with US11894306, the primary recommendation is to closely monitor the progress of IPR2026-00067. The trial is ongoing, and the institution decision (though specific details are not yet publicly available) indicates that the PTAB found the petition to have merit.

The expected Final Written Decision date for IPR2026-00067 is approximately May 21, 2027 (one year from the estimated institution date). It is crucial to obtain and review the full institution decision document for IPR2026-00067 as soon as it becomes publicly available on the USPTO PTAB portal (P-TACTS). This document will detail the specific claims challenged, the prior art relied upon, and the PTAB's reasoning for institution, which will be vital for understanding the scope of the ongoing challenge and potential claim construction issues.
