Welsbach Light Co. v. New York Chemical Refining Co.
U.S. Circuit Court for the District of Southern New York · Decided July 19, 1899 · Acombe
95 F. 1007; 1899 U.S. App. LEXIS 3204
Welsbach Light Co. v. New York Chemical Refining Co.

Opinion of the Court

I .ACOMBE, Circuit Judge.

The Helouis process for treatment of lime crayons, which is relied upon as an anticipation in this case, seems quite different in object and result from that of the patent. Within the range of equivalents indicated by Judge Townsend in the Sunlight Incandescent Gas Lamp Case. 87 Fed. 221, the process of defendant is an infringement. Preliminary injunction accordingly.
