Goodwin Procter Litigators Obtain Dismissal of Remote Access Patent Suit Against Citrix Systems

Goodwin Procter helped Citrix Systems obtain a dismissal of a patent infringement suit filed in the U.S. District Court for the Southern District of Florida.  Judge Adalberto Jordan granted Citrix’s motion for summary judgment, concluding that the one remaining patent claim asserted by the plaintiff against Citrix is invalid in light of the prior art. 

Alexander Orenshteyn filed the suit in April 2002, accusing Citrix of infringing two U.S. patents.  In May 2003, Judge Jordan granted Citrix’s first motion for summary judgment, holding that Citrix did not infringe the asserted patents.  He also imposed sanctions against the plaintiff and his counsel at the time.  In July 2009, the U.S. Court of Appeals for the Federal Circuit upheld the summary judgment of noninfringement for all but one claim and one accused Citrix product, and remanded the case to the district court.  On remand, Judge Jordan granted Citrix’s motion for summary judgment that the one patent claim left in the case is invalid, and again imposed sanctions against the plaintiff and his prior counsel. 

“It has been rewarding to represent Citrix in this quite long-running dispute and we are glad to have had the opportunity to obtain another favorable ruling for Citrix in the case,” said Douglas Kline, a partner in Goodwin’s Patent Litigation Practice.
