Ivoclar Files Patent and Trademark Infringement Lawsuit Against Upcera Dental America

Ivoclar has filed a patent and trademark infringement lawsuit in the United States District Court for the Western District of New York against Upcera Dental America, Inc. The manufacturers of the IPS e.max® lithium silicate products recently announced the action, asserting that Upcera's UP.CAD products infringe several patents issued in the United States covering Ivoclar's lithium-silicate inventions, 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 over the years, and the company will remain active and resolute in enforcing those rights, according to the company, which has a U.S. facility in Buffalo, New York. Global headquarters for the Ivoclar Group are located in Schaan, Liechtenstein.

“This suit against Upcera is just the latest patent enforcement action by Ivoclar where it asserted its patents covering glass ceramics,“ Thad McMurray, General Counsel for Ivoclar North America, says in a press release. “In the past several years, Ivoclar has successfully stopped the sale of infringing glass ceramics in United States and Germany, and it remains resolute in enforcing its glass ceramics patents throughout the world.”

In 2023, Ivoclar celebrated its 100-year anniversary under the theme of “A Century of Innovation”. The group of companies, which sells its products to around 130 countries, has 56 subsidiaries and branch offices and employs roughly 3,700 people worldwide.
