At the end of last month, Copperfield Licensing LLC fired off four separate suits, each asserting a different former Cypress Semiconductor patent that Texas monetization firm IP Edge LLC received from Monterey Research, LLC in November of last year. Copperfield hit Applied Materials (1:21-cv-01399) and Bruker (1:21-cv-01398) in the District of Delaware, as well as KLA (6:21-cv-01012) and MKS Instruments (6:21-cv-01013) in the Western District of Texas. Concurrently, Burbank Technologies LLC, another IP Edge plaintiff, kicked off litigation of another former Cypress patent, suing CenTrak (1:21-cv-01391) and Phyton (1:21-cv-01392) in Delaware.
