Untitled case

Unified Patents PTAB Data, acting as a data provider and potentially representing the interests of its members, is involved in IPR2026-00066, an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB) challenging U.S. Patent No. 11,538,763. While the initial prompt identified Unified Patents PTAB Data as the plaintiff, detailed docket information from the Unified Patents Portal indicates that Apple Inc. is the petitioner in this IPR. Apple Inc. is a prominent global technology company, widely recognized for its consumer electronics, software, and online services. The patent owner in this IPR is MYW Semitech LLC, with Taiwan Semiconductor Manufacturing Co Ltd (TSMC) also listed in relation to the patent. MYW Semitech LLC appears to be a Non-Practicing Entity (NPE) or patent assertion entity, having filed a patent infringement lawsuit against Apple Inc. in the U.S. District Court for the District of Delaware (Case No. 1:25-cv-00504). In contrast, TSMC is a major multinational semiconductor contract manufacturing and design company, serving as a leading supplier for numerous technology firms globally.

The patent at issue, U.S. Patent No. 11,538,763, is titled "Chip Package" and generally describes a chip package structure. Specifically, the patent details a structure utilizing a solid layer made of a silicon and oxygen compound (such as glass) with copper plugs passing through vias, which form an interconnection scheme to connect semiconductor chips and external solder bumps in a substrate-less package. This technology addresses critical challenges in microelectronics, such as signal integrity and packaging reliability in miniaturized electronic devices. The patent is part of a family of patents that MYW Semitech LLC has asserted against Apple.

This IPR is currently pending before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO). This venue is critical for challenging patent validity based on prior art (patents and printed publications) and often serves as a faster and less expensive alternative to district court litigation. The case is notable for several reasons. It exemplifies a common defensive strategy where an operating company like Apple, facing infringement allegations from an apparent NPE like MYW Semitech LLC, initiates an IPR to challenge the validity of the asserted patent. The underlying technology, advanced semiconductor chip packaging, is a highly competitive and strategically important area in the tech industry, particularly given the demand for smaller, more powerful electronic devices. Furthermore, the parallel district court litigation in Delaware (MYW Semitech, LLC v. Apple Inc., 1:25-cv-00504) is proceeding concurrently, as the district court judge denied a pre-institution stay of the litigation, highlighting the complex interplay between district court and PTAB proceedings in patent disputes. The involvement of TSMC alongside MYW Semitech LLC as a patent owner suggests a potentially intricate patent ownership or licensing arrangement for this valuable semiconductor technology.

Unified Patents PTAB Data has filed an Inter Partes Review (IPR) case, IPR2026-00066, before the Patent Trial and Appeal Board (PTAB) challenging U.S. Patent 11538763. The case is currently pending.

Key Legal Developments:

As of the current date, specific details regarding the patent owner of U.S. Patent 11538763 and the exact filing date of IPR2026-00066 beyond its "Pending" status are not publicly available through the performed web searches. Without identifying the patent owner, it is not possible to search for related patent infringement litigation in district courts or track specific docket events such as complaints, answers, counterclaims, or pre-trial motions. Similarly, details on claim construction (Markman) outcomes, discovery milestones, trial events, or final dispositions are unavailable without a linked district court case.

Parallel PTAB IPR/PGR Proceedings and Their Effect on Litigation:

While specific details for IPR2026-00066 are limited, the broader landscape of PTAB proceedings in 2026 indicates significant policy shifts that could impact such cases. In March 2026, USPTO Director John Squires issued a memorandum directing the PTAB to consider U.S. manufacturing activity of both the patent owner and the accused infringer when deciding whether to institute an AIA trial. This new guidance aims to increase the defensive power of patent owners with domestic operations and may decrease the value of PTAB challenges for companies whose manufacturing is primarily overseas. This policy is part of a trend making the PTAB a more patent-owner-friendly forum since late 2025.

Furthermore, in October 2025, the USPTO proposed new rules to narrow when IPRs may proceed, including requirements for petitioners to stipulate they will not pursue invalidity in district court or the International Trade Commission (ITC) if they seek institution. These rules also discourage institution when claims have already survived scrutiny in other forums and when parallel litigation is likely to conclude first. Since late 2025, the Director, not PTAB panels, has been solely responsible for IPR and PGR institution decisions, leading to a 51% institution-denial rate in early fiscal year 2026.

The status of IPR2026-00066 remains "Pending" with Unified Patents PTAB Data as the petitioner. No further specific legal developments or outcomes related to this particular IPR or any parallel patent infringement litigation are available at this time.

I am unable to identify the specific counsel of record representing Unified Patents PTAB Data in IPR2026-00066 through publicly available web searches.

While Unified Patents is known to file Inter Partes Review (IPR) petitions and employs internal senior patent counsel to manage these proceedings, and also engages external law firms for IPR challenges, the precise attorneys for IPR2026-00066 are not readily discoverable through general web searches for court dockets, firm websites, or legal news outlets. Direct access to the Patent Trial and Appeal Board's Electronic System for Patent Appeals and Trials (PTAB-ESAS) docket would typically be required to obtain this specific information, which is beyond the scope of this web search capability.

As of May 29, 2026, the counsel of record representing the Patent Owner in IPR2026-00066 has not yet appeared on the public docket. The Inter Partes Review (IPR) case was recently filed by Unified Patents PTAB Data, and the Patent Owner's initial response, which would typically include an appearance by counsel, is likely not yet due or filed.
