Tesla Patents Upheld in New England Granite Suit

An important electrical decision was handed down at New Haven, Conn., on August 29th by Judge Townsend, in the United States Circuit Court, in the case of the Westinghouse Electric and Manufacturing company against the New England Granite company.

It was on a final hearing on bill and answer raising questions of patentability and infringement of three patents granted to Nikola Tesla, May 1, 1888, for an electric-magnetic motor. The patents in suit relate to the art of electrical transmission of power by the use of mechanically generating alternating currents. They cover the rotating magnetic field.

A decree for an injunction and an accounting as to all claims in suit was granted.
