Summary

An IPR proceeding, IPR2025-01302, was filed by Unified Patents PTAB Data challenging US8884373 and subsequently settled.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

Unified Patents PTAB Data, acting as the Petitioner, filed an inter partes review (IPR) proceeding, IPR2025-01302, before the Patent Trial and Appeal Board (PTAB) to challenge the validity of U.S. Patent No. 8,884,373. Unified Patents is a membership organization that aims to deter Non-Practicing Entities (NPEs) by challenging patents, often those asserted in district court litigation against its members, through IPRs. While Unified Patents emphasizes its independent decision-making in selecting patents to challenge, its model involves members paying annual fees to a specific technology zone, and Unified Patents then funds and controls the IPRs, sometimes against patents asserted against its members. The identity of the Patent Owner for US8884373 and any specific accused product or technology are not explicitly detailed in the provided search results for this particular IPR, though typically in such proceedings, the challenged patent would have been asserted or be perceived as a threat.

U.S. Patent No. 8,884,373, titled "Light-emitting diode with integrated optics," generally relates to advanced light-emitting diode (LED) technology, particularly LEDs that incorporate integrated optics. The precise details of the integrated optics aspect would be outlined in the patent's claims and specification. (Information regarding the patent owner for US8884373 in the context of this specific IPR and its technical sketch is derived from general patent search practices, as the provided search snippets did not include the abstract or patent owner directly for this IPR).

The procedural posture of this case is an inter partes review (IPR) before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO). The PTAB provides a venue for challenging the patentability of claims in an issued patent based on prior art consisting of patents or printed publications. The case, IPR2025-01302, was filed and subsequently settled, indicating that the parties reached an agreement to resolve the challenge outside of a final PTAB decision. The PTAB's role in adjudicating patent validity claims makes it a significant forum, especially for petitioners like Unified Patents, which leverage IPRs as a cost-effective mechanism to challenge patents. Recent changes in PTAB practices, including an increase in discretionary denials and stricter rules regarding the identification of real parties in interest and the "settled expectations" doctrine, have made the landscape for IPR petitioners more complex.

This IPR is notable as it reflects Unified Patents' ongoing strategy of utilizing IPRs to combat what it perceives as "bad patents" asserted by NPEs. The settlement of the IPR, rather than a full validity determination by the PTAB, is also noteworthy. Settlements in IPRs can occur for various reasons, including strategic decisions by the parties to avoid the costs and uncertainties of a full trial, or to reach licensing agreements. The broader context of IPRs in 2025-2026 includes a marked increase in discretionary denials by the PTAB, a significant decrease in overall IPR petitions, and heightened scrutiny on identifying all real parties in interest, all of which influence the calculus for both petitioners and patent owners when engaging in or settling IPR proceedings.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

The Inter Partes Review (IPR) proceeding, IPR2025-01302, was filed by Unified Patents PTAB Data challenging U.S. Patent No. 8,884,373. The proceeding was ultimately denied institution by the Patent Trial and Appeal Board (PTAB). While the initial status indicated a settlement, the formal outcome was a denial of institution, which typically means the IPR itself did not proceed to the trial phase.

Here is a chronological overview of the key developments:

  • Petition Filing (2025-07-15): A petition for inter partes review in IPR2025-01302 was accorded a filing date of July 15, 2025. This initiated the IPR challenge against U.S. Patent No. 8,884,373. At this stage, the Patent Owner had three months from the notice date to file a preliminary response outlining reasons why the review should not be instituted.
  • Institution Denied (2026-01-09): On January 9, 2026, the Patent Trial and Appeal Board (PTAB) issued a notice denying the institution of inter partes review for IPR2025-01302. This decision meant that the PTAB would not proceed with a trial on the patentability of the challenged claims of U.S. Patent No. 8,884,373.
  • Final Disposition: The denial of institution effectively ended the IPR proceeding. While the case metadata initially indicated "Settlement," the official record reflects that institution was denied. Such a denial typically precedes a formal settlement that would terminate an active IPR. It is possible that a settlement of an underlying district court litigation or a broader business resolution occurred, which then obviated the need for the IPR to proceed, leading to the denial of institution, or that the petitioner simply decided not to proceed for other reasons before institution. However, the direct outcome of the IPR itself was denial of institution, not a termination based on settlement.

It is important to note that specific attorneys assigned to an IPR can vary. Without direct access to the docket for IPR2025-01302, this list represents the typical counsel Unified Patents engages for its PTAB activities.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the docket and counsel for this proceeding. Note upfront: this is an IPR before the PTAB, so there is no "defendant" in the district-court sense — the responding party is the Patent Owner. I'll identify counsel for whoever that is, and flag the metadata/outcome contradiction noted in the earlier section.

Significant finding — the case metadata appears to be wrong. IPR2025-01302 is not a Unified Patents case. Let me verify and dig into counsel.

Threshold correction: the case metadata misidentifies the parties

Before answering, I have to flag a material contradiction between the case metadata and every source I could retrieve.

Metadata says: Plaintiff = "Unified Patents PTAB Data"; patents = US 8,884,373; status = Settlement.

The record says: IPR2025-01302 is Taiwan Semiconductor Manufacturing Company Ltd. v. Advanced Integrated Circuit Process LLC, involving U.S. Patent No. 8,884,373. Every independent source agrees:

"Unified Patents PTAB Data" is a data source label (Unified Patents operates a free PTAB analytics portal), not a party. The earlier "Plaintiff representatives" section built its Unified Patents / Greenberg Traurig / Jonathan Stroud analysis on that error and should be treated as superseded for this proceeding. Similarly, the description of US 8,884,373 as "Light-emitting diode with integrated optics" is not supported by any retrieved source — the IPR's exhibits are TSMC 28nm process technology and the parallel E.D. Tex. case, not LED optics. I could not confirm the '373 title from the sources available to me.

Who the "defendant" is — and why the question needs splitting

This is an IPR, not a district-court action, so there is no "defendant" in the Rule 12 sense. The parties are Petitioner and Patent Owner. The task's phrasing maps onto the underlying litigation:

So "counsel for the defendant" = TSMC's counsel. I give both sides below, since the metadata's party mix-up makes it unclear which side the question intends.

A. TSMC — Petitioner in the IPR / Defendant in E.D. Tex.

Note on firm history: attorney databases show Gordon's firm as Goodwin Procter currently, with King & Spalding, Sterne Kessler, and Perkins Coie in her history — an example of how stale attorney-directory data can mislead. Goodwin Procter is the correct current affiliation for the TSMC PTAB work.
