UNITED STATES SUPREME COURT DECISIONS ON-LINE

Letters patent No. 90,284, issued to Joshua Merrill May 18, 1869, for improved manufacture of deodorized heavy hydrocarbon oils, construed and held to be good for the superheating coil, with its steam pipe, &c., referred to in the second claim of the specification, and for the described process by which the oil is deodorized, but not for the product of that process.

This is a suit by Joshua Merrill for an infringement of letters patent No. 90,284, issued to him May 18, 1869, for improved manufacture of two deodorized heavy hydrocarbon oils. The court below found that there was no infringement by the respondents and dismissed the bill, whereupon the complainant appealed here.
