Harvest Technologies files amended patent complaint against Thermogenesis Harvest Technologies announced that it filed an amended patent infringement complaint on February 15 in the US District Court of Delaware against ThermoGenesis (KOOL) and Celling Technologies. The complaint was amended to include Celling Technologies and alleges that the ThermoGenesis' Res-Q 60 BMC system, also sold by Celling Technologies as the ART 21 BMC System, infringes two patents for which Harvest Technology owns the rights. These patents relate to Harvest's proprietary floating shelf technology that has been shown in studies to provide superior cellular concentration. The complaint also requests an injunction against further sales of the product in the U.S. "Harvest Technologies has invested many years and millions of dollars in development of its cellular therapy products," said Gael Tisack, Vice President of Intellectual Property for Terumo Americas Holding. "We will continue to take all steps necessary to ensure that we protect our intellectual property and enforce our patent rights."
