In December 2017 3M and China based Guangzhou Riton Biomaterial reached a mutually satisfactory resolution of all patent matters pending between them in Germany and China that included the parties acquiring licenses from each other. Under the settlement agreement all infringement and invalidity actions were withdrawn.

In June 2014, the District Court of Duesseldorf found that Riton infringed 3M’s European Patent EP 1 474 064 by selling its e-Brace lingual bracket system in Germany. Riton’s appeal against that decision was pending when the settlement was concluded. In July 2015, Guangzhou Riton Biomaterial sued 3M China and other companies in the Guangzhou IP Court, alleging that 3M’s Incognito™ lingual bracket system infringed its patent ZL 2010 102 806 55.0 and its utility models ZL 2012 204 567 88.3 and ZL 2012 205 267 01.5. In reply, 3M filed invalidity actions against Riton’s IP rights before the Patent Reexamination Board. All Chinese actions were pending when the settlement was concluded.
