The “on-sale bar” deems that certain sales of an invention that occur more than one year before a patent application is filed are a bar to patentability. See 35 U.S.C. § 102(b) (pre-America Invents Act (“AIA”)); 35 U.S.C. § 102(a)(1) (AIA). On Monday, June 25, 2018, the Supreme Court granted Helsinn’s petition for certiorari in Helsinn Healthcare S.A. v. Teva Pharmaceuticals USA, Inc., to interpret the on-sale bar provision of 35 U.S.C. § 102 in the AIA. Helsinn Healthcare S.A. v. Teva Pharm. USA, Inc., — S. Ct. —, 2018 WL 1142984 (2018) [SCOTUSblog case file]. The question presented to the Supreme Court is: “Whether, under the Leahy-Smith America Invents Act, an inventor’s sale of an invention to a third party that is obligated to keep the invention confidential qualifies as prior art for purposes of determining the patentability of the invention.” Petition for Certiorari, Helsinn Healthcare S.A. v. Teva Pharm. USA, Inc., No. 17-1229, 2018 WL 1168243 (Feb. 28, 2018).
