A Philadelphia judge has asked the Pennsylvania Superior Court not to hear a medical device distributor’s attempts to prevent the Common Pleas Court from exercising jurisdiction in a mass tort involving allegedly defective blood filters.

Philadelphia Court of Common Pleas Judge Arnold New recently asked the Superior Court to quash the appeal of Angiotech Pharmaceuticals Inc. in In re Option Vena Cava Filter Litigation. The case, litigators say, may wade into novel questions of whether Pennsylvania’s business registration law establishes jurisdiction over out-of-state defendants.
