  3M Files Patent Infringement Lawsuits in Germany to Protect Dental Ceramic
  Coloring Technology

Business Wire

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^TM FlowPen^TM
and Z-CAD^TM Liquid HD, as well as zirconia CAD/CAM blocks sold under the
brand Z-CAD^TM.

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^TM, CopranUltra-T Color^TM and MonolithColor^TM, as well as
zirconia CAD/CAM blocks sold under the Copran Zr^TM 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.

3M is committed to improving oral care through continuous R&D investments. The
company's dental division, 3M ESPE, has been recognized as the most innovative
dental company for the past eight years by the Anaheim Group. This distinction
is awarded based on the number of patent filings, 510k clearances and new
product introductions.
