Vantage Point Technology, a subsidiary of Marathon Patent Group, filed its first lawsuits this week, just over a month after it acquired a portfolio of patents from Hexagon-subsidiary Intergraph. The 22 suits are part of a single campaign and defendants include ASUS, Acer, Amazon, Barnes & Noble, Broadcom, Freescale, HTC, Huawei, Kyocera, LG, Lenovo, Microsoft, NEC, NVidia, Pantech, Qualcomm, Renesas, Samsung, Texas Instruments, and ViewSonic. Each case asserts a single patent that relates to translating virtual addresses in a computing system (5,463,750) and accuses defendants’ mobile devices of infringing the patent-in-suit. Vantage Point acquired the asserted patent from Intergraph, likely as part of the deal reported in October 2013, although it has not been recorded with the USPTO. The patent-in-suit has a priority date of November 2, 1993 and does not appear to have any extensions that would change its expected expiration date of November 2, 2013. RPX saw the asserted patent as part of two separate open market opportunities, one offered in May 2012 and the second in July 2013. In both cases the patent was offered as part of a larger portfolio. This campaign is one of three started this year by Marathon Patent subsidiaries. The other two involve Relay IP and Sampo IP. 11/1, Eastern District of Texas, 2:13cv00908, 2:13cv00909, 2:13cv00910, 2:13cv00911, 2:13cv00912, 2:13cv00913, 2:13cv00914, 2:13cv00915, 2:13cv00916, 2:13cv00917, 2:13cv00918, 2:13cv00920, 2:13cv00921, 2:13cv00923, 2:13cv00924, 2:13cv00925, 2:13cv00926, 2:13cv00927, 2:13cv00928, 2:13cv00929, 2:13cv00930, 2:13cv00931
