CAO Group filed an additional patent complaint against Kerr on February 7, 2014.
This new complaint alleges that Kerr's Demi Ultra LED dental curing light infringes on eight of the patents in the CAO LED curing light patent portfolio. Combined with a previously filed complaint, CAO has asserted 12 patent infringements against several of Kerr's LED curing lights.
"Our advancements in LED curing lights have been widely adopted by the industry," said Densen Cao, PhD, president of CAO Group, in a press release. "CAO will vigorously defend its technology to protect its licensed customers."
