The Federal Circuit today issued two opinions relating to patent law — one affirming a district court’s conclusion, following a bench trial, that the claimant’s inequitable conduct during patent prosecution rendered the patent unenforceable and the other reversing a summary judgment of infringement as to one patent claim and ordering reconsideration of the infringement issue as to a second patent claim. Espeed, Inc. v. BrokerTec, Inc., No. 2006-1385 (Fed. Cir. Mar. 20, 2007) (concerning "methods and systems for trading financial instruments"); Cross Medical Products, Inc. v. Medtronic Sofamor Danek, Inc., No. 05-1415 (Fed. Cir. Mar. 20, 2007) (involving "polyaxial screws").
