Spectra Licensing Group L.L.C., the licensing agent for the “Turbo Code” patents issued to Orange (f/k/a France Telecom), has filed a second 2016 lawsuit, adding a case against Broadcom (LSI) (3:16-cv-00899) to one it filed ten days earlier against Marvell (3:16-cv-00817). The new complaint again asserts a single patent (6,108,388) generally related to iterative signal processing. The defendants are accused of infringement through the manufacture and sale of certain read channel DSP devices. The complaint further alleges indirect infringement of customers, i.e., hard disk drive manufacturers, touting extensive US infringing activity by, e.g., Seagate during the typical sales cycle.
