The troubled litigation campaign of Sockeye Licensing TX LLC has come back to life, with the privately held NPE filing suit in the Central District of California against Belkin (8:17-cv-01218), Lenovo (2:17-cv-05266), LG Electronics (LGE) (5:17-cv-01431), and Microsoft (8:17-cv-01222). The new complaints assert one (8,135,342) of the two patents-in-suit (8,879,987) in the earlier round of litigation, and/or the most recent patent (9,547,981) from the same five-member family, which issued this past January. The patents generally relate to the use of a wireless communications device (e.g., a cell phone) to control and provide network connectivity to standard desktop peripherals (e.g., a monitor and keyboard), with infringement allegations targeting the manufacture and sale of Wi-Fi Certified Miracast products. Belkin, Lenovo, and LGE were defendants in Sockeye’s first attempt to litigate this family of patents, which started with a large set of complaints filed in the Eastern District of Texas and ended with Sockeye’s requests for adverse judgment and cancellation of claims in inter partes reviews (IPRs) responsive to several petitions filed by RPX.
