Uniloc filed seven separate suits on Thursday against eight defendants, including MathWorks, Bitdefender, Nuance Communications, Take-Two Interactive Software, PerkinElmer and its subsidiary Cambridge Soft, The Tiffen Company and TechSmith alleging that the defendants’ software products infringe a patent related to its software registration system (5,490,216).  Uniloc last asserted the ‘216 patent in December 2010 against Foxit and BMC Software, and in 2009 was awarded a $388 million jury verdict in a case against Microsoft for their infringement of the same patent (a case which eventually settled). The most recent string of Uniloc suits occurred last week involving infringement of another patent against nine defendants, including Autodesk, Avid Technology, Corel, GlobalSCAPE, Minitab, Palisade, PerkinElmer, Sony Creative Software, and The Tiffen Company. Since 2003, Uniloc has filed over 40 prior suits against over 80 defendants using its portfolio of product activation and software patents. Ric Richardson is the inventor of the patent-in-suit and Uniloc USA is the exclusive licensee. Uniloc currently has 47 active infringement cases filed in the Eastern District of Texas. 12/27, Eastern District of Texas, 6:2012cv01013; 6:2012cv01014; 6:2012cv01015; 6:2012cv01016; 6:2012cv01017; 6:2012cv01018; 6:2012cv01019.
