Embraer is pursuing trademark applications for its Energia family of reduced-emissions aircraft, with attorneys for the Brazilian manufacturer this month dealing with the initial refusal by the U.S. Patent and Trademark Office (USPTO) of some aspects of the proposed designations on the grounds of “likelihood of confusion.” The applications, which were published on December 14, 2021, cover four nine- to 50-seat models to be powered by a mix of hybrid-electric, hydrogen, duel-fuel gas turbine, and electric propulsion systems.
