Third Wave Files Response to Digene Patent Suit, Files Anti-Trust Countersuit

MADISON, Wis., March 1 /PRNewswire-FirstCall/ — Third Wave Technologies Inc. (NASDAQ:TWTI) today announced that the company has filed its response to the recent patent lawsuit brought against it by Digene Corp. The company’s answer to the suit was filed with the U.S. District Court for the Western District of Wisconsin in Madison, where it is being heard.


Third Wave’s response includes counterclaims against Digene alleging that it has abused its monopoly power to thwart competition in the human papilloma virus, or HPV, diagnostic marketplace.


“Digene filed its patent infringement suit knowing that Third Wave’s Invader(R) chemistry is superior to Digene’s and does not infringe its patent, as our response asserts,” said Kevin T. Conroy, president and chief executive of Third Wave. “While Third Wave prefers competing in the marketplace, we have made a careful decision to file this counterclaim to end the anti-competitive conduct of Digene detailed in our response. We expect to prevail at trial.”


Third Wave has retained the law firm of Kirkland & Ellis to represent it in this lawsuit. The firm, which has years of experience in intellectual property and anti-trust litigation, has successfully represented Third Wave in the past. A scheduling conference will be held on March 15, when an early 2008 trial date is expected to be set.
