"We have invested heavily in our intellectual property for laser dentistry, as well as other medical fields, and currently have over 340 U.S. and international patents and patents pending. We will not tolerate what we believe to be any infringement of our patents, and we will continue to aggressively protect our rights."

BIOLASE currently has royalty agreements related to the sales of Er:YAG lasers manufactured by Fotona d.d., which are sold in the U.S. by Technology4Medicine, LLC, and Hoya Photonics, Inc., which sold its dental business to Photonic Service Group in June 2012.
