In a new lawsuit, Texas-based Xockets says Nvidia has infringed on its patented Data Processing Unit (DPU) technology, which helps make cloud infrastructure more efficient by accelerating data-intensive workloads. Xockets says the chip giant inherited the infringement through its 2020 acquisition of Mellanox. It claims Mellanox initially infringed on its patent after Xockets publicly demonstrated its DPU tech at a conference in 2015.
