The Ninth Circuit Court of Appeals revived two antitrust class actions against a leading dental-device maker accused of monopolizing the clear aligner and intraoral scanner markets by refusing to deal with a competitor. The court clarified the three-step burden-shifting framework for refusal-to-deal claims under Section 2 of the Sherman Act, finding that genuine factual disputes prevent summary judgment and require further examination of whether the defendant's business justifications are pretextual.

This Wire brief sits within Fusion42's coverage of Medtech.
