United States Supreme Court

Helsinn Healthcare S.A. v. Teva Pharmaceuticals USA, Inc., 17–1229

Held that an inventor's sale of an invention to a third party who is obligated to keep the invention confidential can qualify as prior art for purposes of determining the patentability of the invention. The dispute here involved two pharmaceutical companies that disagreed about whether a certain drug was under patent; one of the companies wanted to market a generic version of it. Justice Thomas delivered the unanimous opinion.
