Eizo Nanao filed a complaint for declaratory judgment against Landmark Technology [NPE], seeking declaration that products marketed through Eizo Nanao’s website do not infringe two patents related to exchanging electronic business data with trading partners for ordering and receiving goods.  Landmark Technology has filed over 20 prior suits since September 2008 against over 50 defendants.  Landmark has faced one prior action for declaratory judgment that was filed by Gunze Plastics Engineering Corporation in May 2012.  According to the complaint, Landmark is the exclusive licensee of the patents-in-suit, two of which received re-examination certificates confirming the validity of all claims and allowing 22 additional claims.  The complaint also states that Landmark sent assertion letters to Eizo Nanao in March 2012 offering a license to the Landmark portfolio for a one-time license payment.  8/6, Central District of California, assigned to Judge James V. Selna and referred to Magistrate Judge Robert N. Block, 8:2012cv01263.
