BLTI Biolase Technology, Inc. (MM)

BIOLASE Technology, Inc. (NASDAQ: BLTI), the World's leading dental laser manufacturer and distributor, today announced that it had filed a lawsuit in the Dusseldorf Patent Litigation Court asserting that one of its European competitors is infringing on BIOLASE European Patent EP 1 560 470, which relates to the output of optical energy of lasers. The lawsuit, filed on April 13, 2012, seeks both cash damages and injunctive relief from the courts.

With more than 280 U.S. and international patents and patents pending, the Company has invested heavily in its intellectual property portfolio for laser dentistry and other medical fields.
