Harvest Sues ThermoGenesis Over Medical Technology Patent

Harvest Technologies Corp., a maker of laboratory equipment used in cell therapy, sued ThermoGenesis Corp., claiming its competitor violated patents for separating blood into its components.

ThermoGenesis used technology protected by two patents, titled Blood Components Separator Disk, Harvest claimed in court papers filed yesterday in U.S. District Court in Wilmington, Delaware.

“ThermoGenesis’s actions have, at a minimum, shown willful blindness or indifference” to the patents, Harvest said in its complaint.

Both companies provide technologies used to help separate blood and bone marrow into components, a key part of the process for therapies related to stem cells.

Harvest, based in Plymouth, Massachusetts, is a unit of Tokyo-based Terumo Corp., a medical-device maker.

In October 2008 a distributor, who was not sued as part of the patent case, gave ThermoGenesis confidential information about Harvest’s technology, Harvest claimed in the complaint.

Officials at ThermoGenesis did not immediately return a call left at the company’s headquarters in Rancho Cordova, California.

The case is Harvest Technologies Corp. v. ThermoGenesis Corp., 12-cv-01354, U.S. District Court, District of Delaware (Wilmington).
