Intellectual Ventures (IV) announced it filed suit against Motorola Mobility for alleged infringement of six patents. The complaint, filed in the District of Delaware, claims IV attempted to negotiate a licensing agreement with Motorola Mobility prior to filing suit.  Last month, Google announced it would buy Motorola Mobility for $12.5 billion.  Of the six patents-in-suit, three relate to software and file transfer, one to a docking station for a handset, and one to key exchange between networked devices. One of the patents was the subject of litigation filed against Apple and Microsoft in 2004- Teleshuttle v. Microsoft et al.  In 2006, BTG announced it, “sold its rights to Teleshuttle Technologies LLC’s web-enabled software updating, active desktop and offline browsing patents to TwinTech E.U., LLC, a US company, based in Delaware.”  BTG  also announced it would receive,  “an immediate down payment of $35 million, the gross payment before revenue sharing and costs, plus a share of future profits earned by TwinTech E.U. from commercialising these patents.”  TwinTech EU’s rights were assigned to Intellectual Ventures I, LLC in a merger conveyance recorded September 7, 2011. 10/6, District of Delaware, 1:2011cv00908.
