In a case before Judge Casper, TheBrain Technologies accuses OriginLab of willful infringement of U.S. Patent No. 6,166,736. The patent, which issued on December 26, 2000, claims a graphical user interface that allows for multiple windows and increased ease in accessing multiple windows on a single display (which was apparently not so common when the priority application was filed in 1997). OriginLab sells software applications for scientific graphing and data analysis that are said to read on claims 1-4 of the ‘736 patent, and are accused of direct, contributory, and induced infringement. The allegations of willfulness are based on correspondence to OriginLab in October 2015 laying out which products infringed and providing claim charts in support. While the complaint seeks injunctive relief, the patent will expire on August 21, 2018 , leaving virtually no likelihood that the court will reach a decision on an injunction prior to expiration.
