Palisade Technologies LLP v. T-Mobile USA, Inc.

The patent infringement lawsuit Palisade Technologies LLP v. T-Mobile USA, Inc. (7:24-cv-00262) was filed in the U.S. District Court for the Western District of Texas. While the initial prompt identified T-Mobile as the defendant, publicly available docket information indicates that the named defendant in case 7:24-cv-00262 is actually Micron Technology, Inc., along with Micron Semiconductor Products, Inc. and Micron Technology Texas LLC. It appears there might be a discrepancy in the initial prompt regarding the defendant for this specific case number. T-Mobile is a major mobile telecommunications carrier, while Micron Technology is a global leader in memory and storage solutions. Palisade Technologies LLP is characterized as a non-practicing entity (NPE) or patent assertion entity (PAE), having been formed in July 2024 and acquiring the asserted patents shortly before filing litigation.

The lawsuit accuses Micron Technology and its subsidiaries of infringing U.S. Patent No. 9,281,314, among other patents not listed in the prompt. The '314 patent generally relates to semiconductor memory technology. More specifically, in related PTAB proceedings, the patent is discussed in the context of dynamic random-access memory (DRAM) manufacturing. The accused products are solid-state storage devices and memory modules, including LPDDR5 memory integrated circuits (ICs) and solid-state drives (SSDs), with infringement centered on the incorporation of 3D NAND, USB-C ports, and voltage regulators.

The case is being heard in the Western District of Texas, assigned to Judge David Counts and referred to Judge Derek T. Gilliland. This venue, particularly the Waco Division (though this case is in Midland/Odessa), has been a popular choice for patent plaintiffs due to its fast-paced dockets and perceived plaintiff-friendly reputation. The case is notable as it represents Palisade Technologies LLP's first litigation, following the acquisition of patent assets from Western Digital and its SanDisk subsidiaries. The litigation highlights the assertion patterns of NPEs acquiring portfolios from operating companies. Additionally, Micron has filed an Inter Partes Review (IPR) against the '314 patent (IPR2025-01009), indicating a parallel challenge to the patent's validity at the Patent Trial and Appeal Board (PTAB). As of May 14, 2026, the infringement claims brought by Palisade Technologies, LLP against Micron Technology, Inc. in this case have been dismissed with prejudice, meaning Palisade is permanently barred from re-filing these specific infringement claims.

The case "Palisade Technologies LLP v. T-Mobile USA, Inc." (7:24-cv-00262) in the U.S. District Court for the Western District of Texas does not appear to involve T-Mobile USA, Inc. as a defendant in the information retrieved. Instead, the available search results consistently show the defendants as Micron Technology, Inc., Micron Semiconductor Products, Inc., and Micron Technology Texas LLC. It appears there might be a discrepancy in the provided case metadata regarding the defendant.
