CHICAGO - Ivoclar Vivadent announced this morning at the Chicago Dental Society Midwinter Meeting that it has filed a complaint against Dentsply International and affiliates with the U.S. International Trade Commission, asking that Dentsply's Celtra products "be excluded from importation" into the U.S. and that any such products already in the country have sales and distribution stopped.
Ivoclar claims that the Celtra products infringe on its U.S. patents that protect the company's lithium-silicate technology. This complaint is related to a pending lawsuit Ivoclar filed in U.S. District Court for Delaware last October against Dentsply, also concerning patent protection.
