Overview
Case summary
Charles Heap filed a bill in equity in the Circuit Court for the District of Massachusetts against Henry S. Greene and others, alleging infringement of U.S. Patent No. 377,151 issued to Henry Nicolas Grosselin, fils for a machine for napping cloth. The patent claim involved a combination in a gig mill with a rotary drum, card or teaseling rollers, driving belts, and devices for varying speeds and directions. Defendants raised defenses of patent invalidity and non-infringement. The court, in an opinion by District Judge Carpenter, declined to rule on validity but found the patent limited by prior art, particularly an 1823 English patent to William Davis and an 1878 German patent to Moritz Jahr. The court concluded the patent must be confined to the specific methods described and that defendants did not infringe. The bill was dismissed with costs.
Abstract

Defendants raised defenses of patent invalidity and non-infringement, with the court narrowing the patent scope based on prior art from English and German patents. The court found no infringement by the specific methods claimed and dismissed the bill with costs.
