Abstract

Appears to be a circular or advertisement for Consolidated Electric Light Co. claiming that it is the owner of the Sawyer-Man patents. Refers to patent contests with TAE concerning use of carbon filaments in incandescent lights. Says that Patent Commissioner found that Sawyer and Man had the invention before TAE and that a patent was issued to Sawyer & Man for the incandescent conductor for an electric lamp, consisting of carbon, made from a fibrous or textile material, having the form of an arch or loop. Refers to EEL Co. advertisements that claim it is the owner of the incandescent electric lamp, and states that the Edison Co. has never succeeded in obtaining a decree for the infringement of any of their said patents. Ultimately states that Consolidated Electric Light Co. "will protect all the users of the Sawyer-Man system in the full enjoyment of its privileges," that the controversy in the Patent Office established Sawyer and Man's priority as inventors and the suits pending in the Courts will determine Edison's liability as an infringer, and requests that people who had been deterred from purchasing Saywer-Man lamps by reason of threats from the Edison Co. to contact them.
