Embraer Seeks Trademarks for Energia Aircraft Family

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.

The applications now being processed cover the 50-seat hydrogen-powered E50-H2GT regional airliner, and the 19-seat E19-H2FC. Embraer expects them to enter service, respectively by 2040 and 2035 and serve routes of between 200 nm and 500 nm.

Embraer also is seeking trademark confirmation for a pair of nine-seater aircraft that could be used for a variety of business, utility, and sub-regional applications. It expects to gain certification of the 500-nm-range, hybrid-electric E9-HE by 2030 and have the 200-nm-range, all-electric E9-FE ready for service entry in 2035.

In November, the USPTO published a patent application covering Embraer’s plans for a new vertical and short takeoff and landing aircraft. The design, which differs drastically from the four-passenger eVTOL model under development by its Eve Urban Air Mobility division, shows two sets of airfoils, one extending from the forward section of the fuselage and the other serving as an empennage. Between the two airfoils, drawings show two sets of propellers, each directly connected to an unspecified propulsion unit.

The abstract for the patent application does not specify the proposed power source for the aircraft. It also doesn’t indicate how many seats the model might carry, although, without dimensions being clear, the apparent cabin size would appear to suggest it is a general aviation aircraft with perhaps no more than half a dozen or so seats.
