In November 2017, Align filed suit against 3Shape and its TRIOS intraoral scanning system and Dental System software claiming patent infringement. Despite this action, 3Shape was informed by Align that there were no plans to terminate interoperability. This promise was short lived. In December 2017, Align alerted dentists that it would terminate interoperability, effective January 17, 2018, and then informed 3Shape of the same. These actions have led dentists to lose trust in Align believing that the company made this decision without considering its customers’ best interests.
