Vantage Point Technology’s second round of filings is only 5 cases, against Apple, LSI, MediaTek, Panasonic, and Sharp, much smaller than the 22 litigations filed in the original group of suits less than a month ago.  A subsidiary of Marathon Patent Group, Vantage Point’s cases are all part of a single campaign involving a patent that relates to translating virtual addresses in a computing system (5,463,750). The complaints, including those in the new filings, allege that defendants’ smartphones and tablets incorporate chipsets that infringe the asserted patent. Vantage Point acquired the patent-in-suit from Intergraph in September 2013 as part of a deal that the entity announced in October of this year. The litigated patent has a priority date of November 3, 1993 and there are no USPTO filings to indicate changes to the expected expiration date. However, the new complaints do not mention the patent’s expected expiry. 11/21, Eastern District of Texas, 2:13cv00989, 2:13cv00990, 2:13cv00991, 2:13cv00992, 2:13cv00993
