Overview
Case summary
This patent interference case involves Sydney Smith's claim to invention of a wood-pulp digester lining process. After interference proceedings in the Patent Office awarded priority to Hermann Brungger, Smith filed a bill in equity under Rev. St. § 4915 to revise the commissioner's decision. The defendants demurred, arguing Smith must first appeal to the newly created court of appeals under the 1893 statute. The circuit court sustained the demurrer, holding that the statutory change eliminated the distinction between interference and ex parte cases, requiring exhaustion of the appeal remedy before equity suit. The court found the statutory change remedial and applicable retroactively, rejecting other technical demurrer grounds.
Abstract
In a patent interference proceeding, priority was awarded to one party, prompting the other to file a bill in equity to challenge the decision. Defendants demurred, asserting the need to first exhaust the new appellate remedy in the court of appeals due to statutory changes eliminating distinctions between case types. The court sustained the demurrer, applying the remedial statute retroactively and requiring appellate exhaustion before equity relief.
