Terumo claims Maquet patent infringement case is unfounded
Terumo Cardiovascular Systems (CVS) has responded to a patent infringement complaint by Maquet Cardiovascular, which alleges that Terumo CVS and its parent company, Terumo, had infringed on two patents related to the sale of the Terumo VirtuoSaph Endoscopic Vein Harvesting System, which Maquet claims are its own. 

Terumo CVS said that its policy and its practice are not to infringe on the valid intellectual property rights of any company, and that the VirtuoSaph system is protected by multiple Terumo patents.

“Frankly, we're surprised at this lawsuit as these patents are several years old and our product has been on the market for more than three years with great success,” said Mark DiClemente, vice president of sales at Terumo CVS.  “Our competitor has only recently entered the vessel harvesting market through an acquisition.”

Terumo CVS said it has sold the VirtuoSaph system in the U.S. since January 2005. The product is also distributed in Japan and Asia by Terumo and in Europe by Terumo's European subsidiary, according to the Ann Arbor, Mich.-based company.
