Computer Circuit Operations LLC has sued Acer, MediaTek, and Rockchip (6:20-cv-00419) in a single Western District of Texas complaint over the provision of devices (e.g., tablets, Chromebooks, SoCs, etc.) that feature Double Data Rate (DDR) controllers (e.g., DDR3, DDR4, LPDDR3, LPDDR4, and/or LPDDR4x controller). Infringement allegations against Acer focus on mobile devices that use certain Mediatek Systems-on-Chip (SoCs) and Rockchip SoCs, with allegations as to Mediatek and Rockchip directed to the supplied SoCs themselves. The new case joins active suits filed separately in the same district against Marvell and Socionext this past January; cases against Arastu Systems and VIA Technologies have both been dismissed with prejudice.

The late 2019 peel off by Intellectual Ventures, LLC (IV) of more than 3,500 US assets to a batch of Georgia NPEs has ousted Dominion Harbor Enterprises, LLC from its long-held position as the top NPE assignee of IV divestitures. Meanwhile, as discussed in RPX’s Q1 in Review blog post, throughout the first quarter, NPEs continued filing new litigation asserting patents received from IV, hitting a broad range of targets, including over patents developed by major operating companies.

On the heels of a dismissal in the first case that it filed in its sole litigation campaign, against Arastu Systems in the Northern District of California, Computer Circuit Operations LLC has added three new suits, one each against Marvell (6:20-cv-00044), Socionext (6:20-cv-00046), and VIA Technologies (6:20-cv-00043) in the Western District of Texas. Targeted is the provision of devices and systems (e.g., processors, microcontrollers, and gateways) that feature certain Double Data Rate (DDR) controllers (e.g., DDR3, DDR4, LPDDR3, LPDDR4, and LPDDR4x controllers), with multiple asserted patents received from Intellectual Ventures LLC (IV), which retains an interest in the outcome of Computer Circuit’s litigation.
