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.
