Summary

Advanced Integrated Circuit Process LLC filed a patent infringement lawsuit concerning US Patent 8198686 in the Texas Eastern District Court, which is currently active.

Case overview & background

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

This patent infringement lawsuit was initiated by Advanced Integrated Circuit Process LLC (AICP), a patent assertion entity (PAE) or non-practicing entity (NPE) formed in Texas in June 2024. AICP's managing member and sole owner is AMTL LLC, a Delaware-formed entity. Both AICP and a related entity, Advanced Memory Technologies LLC, share the same Allen, Texas address, consistent with an NPE operational model. AICP acquired the patents-in-suit from Winbond Electronics (Nuvoton Technology Corporation Japan), which had previously obtained them from Panasonic Corporation. The defendants are United Microelectronics Corporation (UMC) and Taiwan Semiconductor Manufacturing Company Limited (TSMC), both leading global semiconductor foundries. AICP alleges that UMC infringes the asserted patents through the manufacture and sale of semiconductor devices, specifically identifying the Qualcomm MDM9625M and Microsemi MPF300T-FCG484E devices, as well as products made using UMC's 22nm and 28nm process nodes. For TSMC, the accused products include semiconductor devices, such as certain Apple, Broadcom, and Qualcomm chips, manufactured using various process nodes, including FinFET technology.

The case is being litigated in the Eastern District of Texas, Marshall Division, before District Judge Rodney Gilstrap, under case number 2:24-cv-00730. A related case against TSMC (2:24-cv-00623-JRG) has been consolidated for pretrial proceedings, with the UMC case serving as the lead. The Eastern District of Texas is a well-known venue for patent litigation, often favored by plaintiffs due to its reputation as a "rocket docket" with a rapid litigation timetable, specific local rules for patent cases, and a history of plaintiff-friendly outcomes. A second docket control order issued on February 21, 2025, sets a jury selection date for June 22, 2026.

The core of the dispute centers on US Patent 8198686, titled "Semiconductor device." This patent broadly describes a semiconductor device incorporating n- and p-type metal-insulator-semiconductor (MIS) transistors with gate electrodes made of different metal materials, designed for high-precision formation and reduced isolation region width. This case is notable due to AICP's apparent status as a PAE asserting patents originally developed by Panasonic against major semiconductor foundries, UMC and TSMC, in a plaintiff-friendly venue. Both defendants have actively challenged the patents, with TSMC filing petitions for inter partes review (IPR) of the '686 patent and others. UMC also filed a motion to dismiss AICP's claims for direct and pre-suit indirect infringement, which Judge Gilstrap denied on September 30, 2025.

Key legal developments & outcome

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

Advanced Integrated Circuit Process LLC (AICP) filed a patent infringement lawsuit in the Texas Eastern District Court (Case No. 2:24-cv-00730) against United Microelectronics Corporation (UMC), which has been designated as the lead case. Taiwan Semiconductor Manufacturing Company Limited (TSMC) is also a defendant in a related member case (2:24-cv-00623). The lawsuit involves US Patent 8,198,686, among others, and is currently active.

Here's a chronological breakdown of the key legal developments:

Filing & Initial Pleadings:

  • 2024-09-06: Advanced Integrated Circuit Process LLC filed the patent infringement lawsuit against United Microelectronics Corporation (UMC) in the U.S. District Court for the Eastern District of Texas. Plaintiff also sued Taiwan Semiconductor Manufacturing Company Limited (TSMC) in a related case. The asserted patents, including US Patent 8,198,686, were acquired by AICP from Winbond Electronics (Nuvoton Technology Corporation Japan) in late July 2024.
  • 2024-10-02: A waiver of service was returned executed by Advanced Integrated Circuit Process LLC for United Microelectronics Corporation. UMC's answer was due by December 6, 2024.
  • 2024-09-25 - 2024-10-03: Attorneys including Ravi Paul Singh Bhalla, Justin Adatto Nelson, and Ian M. Gore appeared on behalf of Advanced Integrated Circuit Process LLC.

Pre-trial Motions of Substance:

  • 2025-02-14: The court issued an initial Docket Control Order, setting key deadlines for the case.
  • 2025-02-21: A Second Docket Control Order was issued, amending some of the previously set deadlines. This order indicated that a jury selection was scheduled for June 22, 2026. It also stated that responses to dispositive motions (including Daubert motions) were due by March 31, 2026.
  • 2025-06-20: Defendant Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) filed a motion for the issuance of a letter rogatory to Nuvoton Technology Corporation Japan. TSMC sought assistance from Japanese authorities to obtain documents and depositions from Nuvoton Japan, a prior owner of the asserted patents, which could be material to TSMC's defenses. AICP had objected to prior discovery requests for information from third parties.
  • 2025-09-30: The Court issued a Memorandum Opinion and Order regarding UMC's Motion to Dismiss Plaintiff's Claims for Direct Infringement and Pre-Suit Indirect Infringement (Dkt. No. 15). UMC's motion was based on allegations that AICP "merely parrots the claim language . . . and fails to provide adequate notice of its claims." The outcome of this motion indicates it was terminated by this order.

Claim Construction (Markman) Outcomes:

  • The Second Docket Control Order noted that the parties are to file a Joint Notice indicating whether the case should be referred for mediation within fourteen days of the issuance of the Court's claim construction order, suggesting that a Markman order is anticipated but had not yet been issued as of the order date. No Markman order has been identified in the available search results to date.

Discovery Milestones with Strategic Significance:

  • 2025-06-20: TSMC's motion for a letter rogatory highlights a strategic effort to obtain information from the patents' previous owner, Nuvoton Technology Corporation Japan, for its defenses and damages theories. AICP had previously resisted producing such documents.

Trial Events, Verdict, and Post-Trial Motions:

  • 2026-06-22: Jury selection is scheduled to begin at 9:00 a.m. in Marshall, Texas.
  • 2026-05-18: A pretrial conference is scheduled for 9:00 a.m. in Marshall, Texas, before Judge Rodney Gilstrap.
  • 2026-05-11: The parties were ordered to notify the Court of any agreements reached during meet and confer regarding outstanding objections or motions in limine. The Joint Pretrial Order, Joint Proposed Jury Instructions, and Joint Proposed Voir Dire were also due by this date.

Settlement, Dismissal, Judgment, or Appeal:

  • The case remains active, with a trial date set for June 2026.

Parallel PTAB IPR/PGR Proceedings:

  • 2025-04-14: Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) filed an inter partes review (IPR) petition, IPR2025-00830, against Advanced Integrated Circuit Process LLC concerning US Patent 8,198,686. TSMC has also filed IPRs against other patents asserted by AICP in related litigation.
  • 2025-07-25: Taiwan Semiconductor Manufacturing Company Ltd. filed another IPR petition, IPR2025-01212, against Advanced Integrated Circuit Process LLC. This IPR targeted a semiconductor interconnect patent using dummy vias.
  • 2025-11-20: IPR2025-01212 received a Discretionary Denial. The status of IPR2025-00830 (related to 8,198,686) is not explicitly stated in the provided snippets beyond its filing.
