The sole tracked case involving KAGA FEI Co., Ltd. is Modulus Systems LLC v. KAGA FEI Co., Ltd., filed on May 27, 2023, in the United States District Court for the Eastern District of Texas. Modulus Systems LLC is characterized as a patent assertion entity (NPE) that actively asserts patents, particularly related to radio frequency module technology and data transmission methods, in venues like the Eastern District of Texas. This case aligns with a common trend of NPEs targeting operating companies in the electronics sector.
Modulus Systems LLC initiated a patent infringement suit against KAGA FEI Co., Ltd. in the Eastern District of Texas, which is currently ongoing.
