Cost Analysis of Post-Grant Review Proceedings Versus European Opposition Proceedings

A previous edition of Nutter’s IP Bulletin included an article analyzing U.S. post-grant review proceedings established by the Leahy-Smith America Invents Act (AIA) in view of European opposition proceedings. As a follow up, our readers may be interested in a cost comparison of the AIA’s post-grant review and European opposition proceedings recently presented by Director David Kappos on the USPTO’s website. Director Kappos indicates that the AIA’s post-grant review procedures are more costly than European opposition proceedings primarily because the AIA’s post-grant review procedures are more akin to litigation (e.g., conducted by patent judges, allow substantial discovery, and create estoppel) while European oppositions proceedings are akin to patent examination (e.g., conducted by examiners, no discovery, and no estoppel).
