Narrative Opinion Summary
This case involves a patent infringement dispute between two parties over the alleged infringement of the '075 and '608 Patents by software known as newlook. The primary legal issues concern the validity of the '075 Patent under 35 U.S.C. § 102(b) due to prior sales of the product, and whether Lansa's newlook software infringes the patents in question. The United States District Court for the Southern District of New York denied both parties' motions for summary judgment on the issues of infringement and invalidity, citing unresolved genuine issues of material fact, particularly regarding the use of algorithms in the newlook software and the identity of products sold before the patent's critical date. The court also addressed motions for sanctions under Rule 11, granting sanctions against ResQNet for inadequate pre-filing investigation but denying sanctions against Lansa. Additionally, the court granted Lansa's motion to amend its answer and counterclaims to include allegations of inequitable conduct, finding no undue delay or prejudice to ResQNet. The proceedings highlight complex issues of patent claim construction, prosecution history estoppel, and the procedural intricacies of patent litigation, illustrating the rigorous standards applied by courts in determining patent validity and infringement.
