3M claims infringement of orthodontic brace patent by Riton
3M Unitek and related businesses have served Guangzhou Riton Biomaterial (Riton) with a lawsuit alleging infringement of 3Mâs patent related to lingual orthodontic braces in a court in Germany. The European patent, No. 1,474,064, âModular System for Customised Orthodontic Appliancesâ covers 3M Unitek's Incognito lingual braces. The latter address the demand for effective and invisible orthodontic treatments. Unlike conventional braces, the Incognito system is bonded to the tongue side of teeth.
3M claims that Ritonâs e-Brace lingual bracket system infringes its patent and is requesting that the court stop Riton from infringing 3Mâs patent and award damages.
