Landmark Technology filed three separate suits against BlissWorld, Brinker and its subsidiaries Chili’s and Maggiano’s, and Cache alleging that the defendants’ websites and electronic data interchange systems infringe two patents related to online sales. Landmark Technology has aggressively fought to protect its e-commerce based patents over the past several years. In December alone, Landmark Technology sued thirteen online retailers over the same patents-in-suit, including Burberry, Belk, Jos. A. Bank, Airgas, Fifth & Pacific Companies, Kate Spade, Juicy Couture, and Lucky Brand Dungarees. Since 2008, Landmark Technology has filed over 40 suits against over 100 companies and retailers who either sell goods and services online, or conduct business using e-commerce technology. All previous suits have concluded either in settlement or voluntary dismissal.  Landmark has also been involved in two declaratory judgments. The first resulted in the court’s granting of Landmark’s motion to dismiss for lack of personal jurisdiction, and the other resulted in a joint stipulation of dismissal.  Landmark currently has over 20 active cases in the Eastern District of Texas against various online retailers.  12/21, Eastern District of Texas, 6:2012cv00997; 6:2012cv00998; 6:2012cv00999.
