Longhorn IP Plaintiff Hits NVIDIA in West Texas

Hamilcar Barca IP LLC is a Longhorn IP LLC entity holding a portfolio of former MediaTek patents. It has now filed its first affirmative lawsuit, accusing NVIDIA (1:25-cv-00620) in a new Western District of Texas complaint of infringing two of them, one described as directed to “processing noise interference according to an error feedback mechanism of a Serial Advanced Technology Attachment (‘SATA’)”; the other, to computing systems operating in multiple security environments. The respective accused products are “any device or system implementing SATAv3 or later, including but not limited to the NVIDIA SN2000 switch and NVIDIA DGX Systems” and “the ARMv8-A-compliant data or central processing units, and other systems and devices made, imported, or sold by NVIDIA supporting the ARMv8-A or later architecture”.
