Dental restoration material manufacturer Ivoclar has filed a patent and trademark lawsuit against the California-based manufacturer Upcera Dental America.
In the suit filed in the U.S. District Court for the Western District of New York, Ivoclar claims that Upcera's UP.CAD products infringe on patents for its lithium-silicate products and a trademark related to its millable dental ceramics.
Ivoclar has invested substantial resources in the research and development of its IPS e.max CAD technology, products, and its intellectual property rights, and the company will remain resolute in enforcing those rights, it said in a press release. During the last several years, Ivoclar has stopped the sale of infringing glass ceramics in the U.S. and Germany, according to the company.
