Brandywine Communications Technologies filed six new suits last week, continuing its suing spree against defendant ISP’s. Four of the suits were filed on January 10 against American Network Communications, Front Range Internet, NATCO Communications, and Precision Communications. On January 11, Brandywine filed two additional suits against Galaxy Internet Services and G4 Communications. In all suits, Brandywine alleges that the defendants’ DSL service and equipment infringe six patents related to DSL and modem based communications (5,206,854; 5,251,328; 5,812,537; 5,828,657; 6,970,501; 7,894,472). Just two weeks prior, Brandywine filed similar suits against over 50 ISP’s with the same patents.  Brandywine currently has over 65 active cases, including a declaratory judgment against Brandywine, filed on January 10, by medical device company Estech.  The patents-in-suit were assigned to Brandywine by Rembrandt IP in 2010 and were part of a portfolio of patents from AT&T/Lucent spinout/DSL chip provider Paradyne that Rembrandt IP acquired in 2006 from Paradyne acquirer, Zhone.  RPX reviewed the patents as an open market opportunity (Rembrandt_DSL-Acq) in February 2010.  1/11, District of Massachusetts, 1:13cv10068; District of New Hampshire, 1:13cv00017; 1/10, District of Colorado, 1:2013cv00054; 1:2013cv00056; Western District of Arkansas, assigned to Honorable Susan O.
