Inventor-backed Advanced Cluster Systems, Inc. (ACS) has revived its sole litigation campaign, launched in October 2019 with a suit against NVIDIA, with separate cases against Advanced Micro Devices (AMD) (7:24-cv-00244) and Intel (7:24-cv-00245) in the Western of Texas. The five asserted patents, four of which are asserted in litigation for the first time, are broadly directed to cluster computing. AMD is accused of infringement through the provision of server and workstation products that use AMD’s MI-series accelerators, as well the accelerators themselves; and Intel, over server and workstation products that use Intel’s Habana AI-series accelerator products, the accelerators themselves, and certain Xeon Scalable Processor-series products.
