While many patent litigators have no plans to litigate in bankruptcy court, it is a possibility if the infringer of a client’s patent files for bankruptcy. The United States Bankruptcy Court for the Eastern District of Wisconsin recently conducted a Markman hearing. How did that happen?  After being sued for patent infringement in district court, the alleged infringer sought refuge in the bankruptcy court, staying the district court litigation. The plaintiff then filed a claim in the defendant’s bankruptcy case, which ultimately triggered the bankruptcy court’s jurisdiction. While rare, other bankruptcy courts have conducted claim construction proceedings. As discussed herein, the bankruptcy court ultimately granted a joint request for vacatur, prompting us to revisit the doctrine of vacatur.

On October 9, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision in HZNP Medicines LLC v. Actavis Laboratories UT, Inc. affirming the U.S. District Court for the District of New Jersey’s findings of invalidity and noninfringement of certain claims of some of the asserted HZNP (Horizon) patents, as well as the district court’s finding of nonobviousness of one claim of another Horizon patent. The finding of nonobviousness means that Actavis, owned by generic drug maker Teva Pharmaceuticals, is enjoined from engaging in the commercial use, offer for sale, or sale of its product covered in its Abbreviated New Drug Application (ANDA) until the expiration of U.S. Patent No. 9,066,913 (the ‘913 patent) in 2027.
