The Patent Trial and Appeal Board (PTAB) has denied institution in just over 25% of the inter partes review petitions it has ruled on. A denial may be considered a "win" for the patent owner, whose claims do not then have to undergo a proceeding where, historically, the chances of survival are not very good. Further, for now, the patentability standards applied before the PTAB seem less favorable to the patent owner than before the U.S. district courts. When faced with an IPR petition, patent owners may choose to first try to prevent institution, particularly since decisions on institution are not appealable. In this article, Finnegan attorney Thomas L. Irving explores technical bases on which patent owners may argue for denial of IPR petitions.
