Overview
The bill is dismissed with costs. The Chichester patent is void for want of invention.
Case summary
William Schwarzwaelder & Co., owner of Chichester patent No. 328,838 for folding chair improvements, sued City of Detroit and officials of Detroit House of Correction for patent infringement. Defendants manufactured chairs at the correctional facility that allegedly infringed the patent. The court dismissed the bill, finding the patent invalid for lack of patentable invention. The chair combined old elements from prior patents without producing new results, constituting mere mechanical improvement rather than invention. The court also rejected joint invention defense due to insufficient evidence to overcome presumption from patent. Commercial success of the chair was deemed insufficient to establish patentability.
Abstract
Patent owner sued city and officials for infringement based on folding chair improvements produced at a correctional facility. Court dismissed the case, invalidating the patent for lack of invention as it merely combined old elements from prior patents without new results, rejecting joint invention defense due to insufficient evidence. Commercial success was deemed inadequate to establish patentability, resulting in dismissal with costs.

Holdings of the court
Validity of Chichester patent
Chichester patent No. 328,838 is void for want of invention
The chair is combination of old elements; variations from prior constructions are suggestions of mechanical skill, not invention; producing cheaper/more durable chair using same means as prior patents is improvement in degree but not patentable invention
unanimousnon-binding
Joint invention defense
Presumption from patent that Chichester was inventor prevails
Patent is prima facie evidence patentee was original inventor; testimony of Williams claiming joint invention denied by Chichester creates equipoise insufficient to overcome presumption
unanimousnon-binding
Commercial success as evidence of invention
Ready sale and market supersession given weight only when novelty/invention in doubt
Commercial success is unsafe criterion per se for patentability; only considered when invention question is doubtful
unanimousnon-binding
