Third Wave Technologies, Inc. Responds To Digene Corporation Lawsuit

MADISON, Wis., Jan. 12 /PRNewswire-FirstCall/ -- Third Wave Technologies Inc. today responded to a lawsuit filed against it by Digene Corp. that alleges Third Wave is infringing unidentified claims of U.S. Patent No. 5,643,715. The '715 patent relates to a single HPV type, 52, the prevalence of which is 0.5% of HPV-positive specimens in the United States, according to Digene's package insert. The suit was filed in U.S. District Court for the Western District of Wisconsin in Madison, Wis.

"Third Wave's confidence in its ability to operate in the HPV market remains strong and unchanged," said Kevin T. Conroy, president and chief executive of Third Wave. "We took great care to create a detection method free from the limited scope of the '715 patent's claims. Third Wave's Invader(R) chemistry operates differently from any other nucleic acid analysis chemistry and is well-protected by intellectual property rights of its own.

"Customers tell us that Digene's test suffers from many challenges, and Third Wave's dedicated team of scientists has developed HPV products, currently in clinical trials, that address those shortcomings and better meet the needs of clinical labs, physicians and their patients," Mr. Conroy said. "Third Wave remains firmly committed to delivering choices to physicians and women for detecting high-risk HPV infections."
