Recent months have seen Bell Semiconductor, LLC (Bell Semic) file an ongoing flood of litigation targeting chipmakers over semiconductor products made using Electronic Design Automation (EDA) tools from Cadence Design Systems, Synopsys, and/or Siemens. Now, Cadence and Synopsys have responded with a jointly filed declaratory judgment complaint against Bell Semic (1:22-cv-01512), seeking a judgment of noninfringement and invalidity for six semiconductor design patents asserted against their customers throughout the plaintiff’s “sprawling” campaign. Meanwhile, Bell Semic has continued to pile up new complaints throughout November since suing Silicon Laboratories on the first, filing additional complaints against Ambarella (3:22-cv-00323), Analog Devices (1:22-cv-11901), Infineon (1:22-cv-11926), Marvell (4:22-cv-11906), NVIDIA (1:22-cv-11933), NXP (3:22-cv-01794), Qualcomm (3:22-cv-01796), Rockchip Electronics (4:22-cv-00962), Socionext (2:22-cv-12749), and Western Digital (8:22-cv-02083)—each of which has been sued by Bell Semic before.
