Covidien Files Counterclaims Against Applied Medical Corporation

Covidien COV today announced that a subsidiary of the Company filed an answer and counterclaims against Applied Medical Resources Corporation for patent misuse, non-infringement and invalidity. The action is related to Applied's recent claim against unspecified Versaport Plus trocar products for alleged infringement of a reissue patent, which was issued on May 17, 2011, and will expire February 10, 2013. The reissue patent is based on U.S. Patent 5,407,433 which was previously invalidated when a Federal Court granted a motion for summary judgment by a Covidien affiliate.
