Neodrón Limited has followed up recent suits, one against Infineon Technologies (Cypress Semiconductor) in the Western District of Texas and another against TI in the Eastern District of Texas, with a complaint filed against STMicro (6:20-cv-00560), also in the Western District. The NPE targets the provision of certain STM touchcontrollers—including the “FTM5CU56A, and STM32 microcontrollers, such as STM32F0, STM32F3, STM32FL0, STM32L1, and STM32L4 series and STM32L0538-DISCO and STM32F072B-DISCO”—with four touch sensitive control patents, three of which are familiar to existing campaign defendants and one of which is new to the litigation.
