Crossroads Files Appeal On Patent Invalidation

Austin-based Crossroads Systems continues to battle for survival, saying on Thursday that it has filed an appeal with the United States Court of Appeals for the Federal Circuit, regarding a recent set of patent decisions which found a number of Crossroads' patent unpatentable. The patents in question are U.S. Patent Nos. 6,425,035, 7,051,147, and 7,934,041, which all involve technology for network storage systems. Crossroads had been using these patents in lawsuits against Cisco and others. Crossroads recently sold off its entire product business, and said it plans to sell off excess patents, to help fund its patent strategy.
