American Patents LLC has kicked off a third litigation campaign in the last three months, suing Analog Devices, Cypress Semiconductor, Marvell, and MediaTek (6:18-cv-00356) in a single complaint. A family of three patents broadly pertaining to hardware circuits for variable-length coding and decoding of media data are asserted, with the NPE targeting various chipsets/embedded processors/microcontrollers built around certain ARM core processors. The American Patents complaint highlights Analog Devices’ ADSP-SC584, Cypress Semiconductor’s Traveo S6J3310, Marvell’s ARMADA 7K product family, and MediaTek’s MT6595 and Helio X27 product families, citing to various ARM documentation to lay out at least initial infringement allegations.
