Berger Montague Named a Law360 Legal Lion of the Week for Ninth Circuit Invisalign Antitrust Win

Berger Montague, a leading national plaintiff law firm, has been named one of Law360’s “Legal Lions of the Week” for persuading the U.S. Court of Appeals for the Ninth Circuit to revive two certified antitrust class actions alleging that Align Technology, Inc., the maker of Invisalign, illegally monopolized the markets for clear aligners and intraoral scanners.

“This is an important win for the dentists and patients who allege they paid more for Invisalign because Align shut out competition,” said Joshua P. Davis, Shareholder and Co-Chair of Berger Montague’s Appeals & Complex Briefing Department. “The Ninth Circuit recognized that whether Align’s stated reasons for cutting off a rival were pretextual, and whether they in fact benefitted competition, are questions for a jury, not ones to be decided on summary judgment, and we look forward to presenting that evidence at trial.”

The decision revives two certified class actions, one on behalf of dentists who purchased Invisalign directly from Align and one on behalf of consumers who purchased clear aligners indirectly, alleging that Align unlawfully monopolized the markets for clear aligners and intraoral scanners. The cases now return to the U.S. District Court for the Northern District of California for trial.

Plaintiffs allege that Align, which they contend controls approximately 90 percent of the U.S. clear aligner market, terminated a 2015 interoperability agreement with rival scanner maker 3Shape in 2017, cutting off 3Shape’s TRIOS intraoral scanners from Invisalign workflows. Plaintiffs further allege that Align used anticompetitive discounting, bundling, and exclusivity agreements to restrict competition in both markets. Align argued that it ended the arrangement for legitimate reasons related to patent litigation, but the Ninth Circuit held that plaintiffs presented sufficient evidence that factual disputes over Align’s true motivation, and the effect of its actions on competition, preclude summary judgment.

The U.S. Department of Justice and the American Antitrust Institute filed amicus briefs supporting the plaintiffs on appeal, and the Department of Justice also participated in oral argument.
