Win or Go Home? Standing to Appeal PTAB Decisions Upholding Patentability to the Federal Circuit Before Submitting a Biosimilar Marketing Application

Biosimilar developers have been aggressive in filing petitions for inter partes reviews (IPRs) of biologics patents before the Patent Trial and Appeal Board (PTAB), many of them preceding the filing of a marketing application.  Such early IPRs are attractive to biosimilar makers, because they provide a chance to challenge innovator patents years before the biosimilar maker files a marketing application with FDA.  Since a petitioner need not have Article III case-or-controversy standing to bring an IPR, the remoteness and uncertainty of future infringement in such circumstances does not preclude these early IPRs.  Under settled precedent, however, a biosimilar maker must have Article III standing to seek a Federal Circuit appeal if the PTAB issues a final decision upholding the challenged patent.  A decision expected from the Federal Circuit this quarter in Momenta Pharmaceuticals, Inc. v. Bristol-Myers Squibb Co., No. 17-1694 (Fed. Cir. argued Dec. 5, 2017) will address how and when a biosimilar maker can establish that standing.

The Federal Circuit’s First Application of the AIA’s On-Sale Bar: Implications for Bio/Pharma

When a small pharmaceutical company discovers a new medicine, it’s not uncommon for the company – which may not itself have the resources or infrastructure to get that medicine to patients – to seek a distribution partner early in development.  If the partners make a deal – say the distributor pays for the right to sell the drug (if it gets approved) – and the partners publicize the existence of the deal (but not the full details of the medicine), does the deal bar a patent filed more than one year later?  In Helsinn Healthcare S.A v. Teva Pharms. USA, Inc. (May 1, 2017), a unanimous panel of the Federal Circuit ruled that the on-sale bar of the America Invents Act (AIA) precludes such a patent, just as the pre-AIA on-sale bar would.  But, in a decision with the potential to chill deals between small bio/pharma companies and potential commercialization partners, the court left unresolved some important questions about the meaning of the AIA’s on-sale bar.
