CAO Group Inc. of West Jordan, Utah, filed a lawsuit against dental laser company Biolase Technology Inc. in US District Court, alleging patent infringement involving Biolase’s ezlase diode laser, the California company announced. The only claimed novelty of the single asserted patent pertains to how excessive fiber is stored and does not relate to the actual design, features or functions of the ezlase laser. The Biolase ezlase is used by dentists and hygienists to whiten teeth, and has received FDA 510(k) clearance for pain relief and for therapy in sports medicine, orthopedics, physical therapy and chiropractic medicine applications. “With close to 300 issued and pending patents, we are very confident in the breadth of our intellectual property portfolio and in the strength of our laser technology,” said Federico Pignatelli, chairman and CEO of Biolase. “We are quite intrigued by this attack on Biolase, and we will fully and vigorously defend Biolase against any allegations levied by CAO which are without merit.” The lawsuit was filed without first contacting Biolase.
