Supreme Court Hears Helsinn v. Teva: Does On-Sale Bar Capture Secret Sales

On the morning of Tuesday, December 4th, the U.S. Supreme Court held oral arguments in the case of Helsinn Healthcare S.A. v. Teva Pharmaceutical USA (transcript of oral arguments here). This case asks the nation’s highest court to determine whether the sale of a patented invention which required the purchaser to keep the invention confidential (i.e.: a “secret sale”) qualifies as invalidating prior art under the on-sale bar found in 35 U.S.C. § 102(a)(1)… Justice Samuel Alito said that the most serious argument for Jay to deal with was the plain meaning of the new statutory language under the AIA; if “on sale” meant on sale publicly and privately, then the “or otherwise available to the public” language wouldn’t make much sense in the context of the statute.

Federal Circuit Clarifies On-Sale Bar Under America Invents Act

In Helsinn Healthcare S.A. v. Teva Pharms. USA, Inc., the Federal Circuit reversed the district court and held that Helsinn’s pre-AIA patent claims, “were subject to an invalidating contract for sale prior to the critical date,” and furthermore, “the AIA did not change the statutory meaning of ‘on sale’ in the circumstances involved here.” The asserted claims of the post-AIA patent were also ready for patenting prior to the critical date… The on-sale bar, before and after the AIA, does not require a finding that the offer or sale disclosed the details or claimed features of the invention, so long as the product embodies those features when sold. An invention is reduced to practice, and ready for patenting, when it is reasonably shown to work for its intended purpose, which for a pharmaceutical product is not contingent upon FDA approval.
