Overview
Case summary
This patent infringement case involves appeals from a decree granting a perpetual injunction against Standard Elevator Company et al. for infringing claims of patents No. 328,614 and No. 456,122, owned by Crane Elevator Company et al. The Circuit Court of Appeals for the Seventh Circuit addressed jurisdictional issues, holding the decree final and appealable under Section 6 of the 1891 Act, as it conclusively determined patent ownership, validity, infringement, and injunction, despite a pending accounting. On the merits, the court affirmed the validity and infringement of patent No. 456,122 (elevator control device with two counterbalancing cables), finding Reynolds the first inventor over Smith. For patent No. 328,614 (hydraulic elevator improvements), claims 2 and 4 were upheld as valid and infringed, but claim 6 was valid not infringed. The court also ruled that certified copies of patent office assignments provide prima facie proof of title. The majority opinion by SHOWALTER was joined by BUNN, with WOODS dissenting on several points, including the finality of the decree and priority of invention.
Abstract
The appeals court upheld jurisdiction, deeming the decree final and appealable despite a pending accounting, as it conclusively resolved patent ownership, validity, infringement, and injunction. On the merits, it affirmed validity and infringement for one patent and most claims of the other, establishing the patentee as the first inventor and certified assignments as prima facie proof of title, while reversing as to one specific claim due to non-infringement. The decree was affirmed except for that claim, with directions to vacate the reference and dismiss the bill for want of equity, and the case remanded.
