ST. PAUL‚ Minn. – (November 6, 2013) – As part of its ongoing program to license to the dental industry 3M's patented technology that enables the coloring of ceramic-based dental restorations, and to protect its technology against unlicensed users, 3M has filed two patent infringement lawsuits in Düsseldorf, Germany.
The first lawsuit is against Metoxit AG, and alleges infringement of 3M’s patent rights by coloring liquids sold under the brands Z-CAD™ FlowPen™ and Z-CAD™ Liquid HD, as well as zirconia CAD/CAM blocks sold under the brand Z-CAD™
The second lawsuit is against White Peaks Dental Systems GmbH & Co. KG and alleges infringement of 3M’s patent rights by coloring liquids sold under the brands CopranColor™, CopranUltra-T Color™ and MonolithColor™, as well as zirconia CAD/CAM blocks sold under the Copran Zr™ brand.
3M’s patented technology enables the coloring of unshaded ceramics by color-matching dental restorations to the natural color of patients’ teeth. 3M has licensed its patents to much of the dental industry, including Vita Zahnfabrik H. Rauter GmbH & Co. KG, and Vident, Inc., Dentsply Prosthetics U.S. LLC and Dentsply International Inc., Zirkonzahn GmbH, Wieland Dental + Technik GmbH & Co. KG, and Ivoclar Vivadent AG.
