Bell Semiconductor, LLC filed suit against Texas Instruments, Corp. on 28 June 2023 in the Eastern District of Texas (Case No. 4:23-cv-00609), before Judge Amos L. Mazzant. The complaint asserted infringement of three patents covering semiconductor packaging and substrate technologies: US7345245B2 (isolated Vss plane for high-speed circuitry ground isolation), US8530375B2 (robust high-density substrate design for thermal cycling reliability), and US7646091B2 (semiconductor package architecture). The products at issue related to advanced semiconductor packaging solutions relevant to Texas Instruments’ broad integrated-circuit portfolio.

The case closed on 30 December 2024 pursuant to a joint motion under Fed. R. Civ. P. 41(a)(2). The court ordered plaintiff’s claims dismissed with prejudice — permanently extinguishing Bell Semiconductor’s ability to assert the same claims against Texas Instruments in any future proceeding. Texas Instruments’ counterclaims, by contrast, were dismissed without prejudice, preserving the company’s optionality to pursue those claims at a later date if warranted. Each party was ordered to bear its own attorneys’ fees, costs, and expenses, suggesting a negotiated resolution without a prevailing-party award.

At 551 days, the litigation ran well past many pre-trial resolutions in E.D. Texas, suggesting that substantive motion practice or discovery occurred before the parties reached their agreement. The asymmetric dismissal terms — with prejudice for plaintiff, without prejudice for defendant’s counterclaims — are commercially significant: they suggest Texas Instruments may have obtained meaningful concessions, though the precise terms of any underlying agreement remain confidential. The public record does not disclose whether a licensing arrangement, covenant not to sue, or other commercial consideration accompanied the dismissal.
