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 D?sseldorf, Germany.
The first lawsuit is against Metoxit AG, and alleges infringement of 3M?s patent rights by coloring liquids sold under the brands Z-CADTM FlowPenTM and Z-CADTM Liquid HD, as well as zirconia CAD/CAM blocks sold under the brand Z-CADTM.
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 CopranColorTM, CopranUltra-T ColorTM and MonolithColorTM, as well as zirconia CAD/CAM blocks sold under the Copran ZrTM 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. Through these licensees, patients around the world enjoy the benefits of dental restorations matching the natural color of their teeth. 3M remains open to licensing this technology to other interested parties.
