Marine Polymer Technologies Inc. added a notch to its belt in a long-running patent spat against HemCon Medical Technologies Inc. over bio-compatible polymers used to make hemostatic bandages.
Danvers, Mass.-based Marine Polymer won an injunction from the U.S. District Court for New Hampshire, barring HemCon from selling its HemCon bandage, ChitoFlex dressing and HemCon dental dressing "and any other products which are no more than colorably different from these infringing products," for as long as the patent is in effect, according to court documents.
A jury handed Marine Polymer a $29.4 million verdict in April, finding that Portland, Ore.-based HemCon infringed the patent for “Biocompatible Poly-ß-I→4-N-Acetylglucosamine,” which MPT uses to make its SyvekPatch bandage, according to the documents.
HemCon said it plans to file for an emergency stay of the injunction, pending an appeal. It also plans to appeal the jury verdict.
Marine Polymer president and CEO Sergio Finkielsztein said his firm intends to “vigorously oppose” any HemCon appeals.
“We are very pleased with the court’s recent orders confirming the validity and enforceability of our patent, and we aim to make sure that all those acting in concert with HemCon are aware of the terms of the injunction as entered by the court,” Finkielsztein said in prepared remarks.
