Patents fmean continued growth for industry leader.

BIOLASE Technology, Inc., (Nasdaq: BLTI), announced it has obtained two new patents that further strengthen the technological advantages of its Waterlase technology. The new patents include one issued in the U.S. protecting unique aspects of the Waterlase and the other in Canada protecting the use of any suitable laser wavelength for treating bone and tooth tissue.

The new U.S. apparatus patent is related to BIOLASE's Waterlase technology and has specific claims that define specific parameters that allow for precise and effective tissue cutting. This patent has a priority date of 1995 and contains 82 claims, of which three are independent.

The Canadian patent is based on Waterlase's ability for treating bone and tooth tissue. This patent has a priority date of 1990 and is very broad with claims not limited to specific wavelengths. This is BIOLASE's second patent

granted in Canada -- the first was related to the same technology using lasers with water with claims specific to certain laser wavelengths.
