Buchanan Obtains Win for Hamilton Technologies LLC at the U.S. Court of Appeals for the Federal Circuit, Clearing a Legal Hurdle for Hamilton’s INTELLiVENT-ASV® Ventilator Products

WASHINGTON (July 2023) - Buchanan obtained a favorable decision on June 28, 2023 from the U.S. Court of Appeals for the Federal Circuit (CAFC) on behalf of Hamilton Technologies LLC, affirming a 2021 decision by the U.S. Patent and Trademark Office Patent Trial and Appeal Board.

Hamilton Technologies’ favorable decision from the CAFC clears a hurdle with regard to Hamilton’s roll out of its innovative INTELLiVENT-ASV® ventilator product line.

The case stems from global assertions of patent infringement by Dr. Fleur Tehrani. The CAFC ultimately held challenged claims of the asserted patent to be invalid, clearing a pathway for Hamilton to proceed with pending FDA approval of its INTELLiVENT-ASV® product line.

The CAFC’s decision aligns with a favorable decision for Hamilton before the United Kingdom’s Intellectual Property Enterprise Court (IPEC) in 2022.

Hamilton Technologies LLC is a leading manufacturer of critical care ventilation solutions for a wide variety of patient populations, applications, and environments, and is a leading global innovator of cutting edge, automated closed-loop mechanical ventilation.

Patrick C. Keane, Matthew L. Fedowitz, and Ralph Fisher, shareholders of Buchanan, represented Hamilton Technologies LLC before the U.S. Court of Appeals for the Federal Circuit and the U.S. Patent and Trademark Office Patent Trial and Appeal Board.
