Case Brief Summary & Legal Analysis
tl;dr: Sears copied Stiffel’s unpatented pole lamp. The Supreme Court held that federal patent law preempts state unfair competition laws, meaning Sears was free to copy the product’s design because unpatentable articles are in the public domain and cannot be given state-level monopoly protection.
Legal Significance: This case established the “Sears-Compco doctrine,” holding that federal patent law preempts state unfair competition laws that prohibit the copying of unpatented articles. This protects the public’s right to copy what federal law leaves in the public domain.
Case Facts & Court Holding
Key Facts & Case Background
Respondent Stiffel Company designed and successfully marketed a “pole lamp.” Stiffel secured both mechanical and design patents for the lamp. Shortly thereafter, petitioner Sears, Roebuck & Co. began selling a substantially identical lamp at a much lower price. Stiffel sued Sears for patent infringement and for unfair competition under Illinois law. The District Court held Stiffel’s patents invalid for want of invention but found Sears liable for unfair competition. The court reasoned that Sears’s exact copying of the lamp was likely to cause, and had already caused, confusion in the marketplace as to the source of the goods. It enjoined Sears from selling lamps identical or confusingly similar to Stiffel’s. The Court of Appeals affirmed, holding that under Illinois law, a mere likelihood of confusion as to source was sufficient to constitute unfair competition, without any need to prove that Sears was “palming off” its products as Stiffel’s. The Supreme Court granted certiorari to determine if this application of state law was compatible with federal patent law.
