Case Brief Summary & Legal Analysis

General Brief
3 min read

tl;dr: A steel manufacturer, after being notified of a competitor’s patents, proceeded to sell infringing products without seeking legal advice. The court found this constituted willful infringement, upholding the patents’ validity and remanding for consideration of increased damages.

Legal Significance: This case establishes that a potential infringer with actual notice of a patent has an affirmative duty to obtain competent legal advice before commencing potentially infringing activity to avoid a finding of willful infringement.

Case Facts & Court Holding

Key Facts & Case Background

Crucible Inc. owned two patents (‘518 and ‘934) for high-speed tool steels produced through a powder metallurgy process. This process achieved a novel combination of full density and fine, uniformly dispersed carbides, solving a long-standing problem in the art. Before Stora Kopparbergs Bergslags AB (Stora) began selling its competing steel products in the United States, Crucible warned Stora that its products would infringe certain allowed claims. An internal memorandum from Stora’s chief technical expert acknowledged Crucible’s patent rights and the high likelihood of infringement. The memo outlined a strategy to challenge the patents’ validity in court but proceeded on the assumption that Stora’s products would infringe if the patents were upheld. Stora did not obtain an opinion from competent U.S. patent counsel regarding validity or infringement before commencing its sales. The district court found the patents valid and infringed but declined to award increased damages. After the trial concluded, Stora sold the infringing business to Kloster Speedsteel AB (Kloster).

Court Holding & Legal Precedent

Issue: Did the defendant’s failure to obtain competent legal advice after receiving actual notice of the plaintiff’s patent rights, coupled with its internal assessment of infringement risk, compel a finding of willful infringement?

Yes. The district court’s implicit finding of non-willful infringement was clearly erroneous.
