A recent PTAB decision highlights the difficulty of persuading the Board to allow live testimony from an expert during post-grant proceedings. In IPR2017-00433, the PTAB denied patent owner Polaris Industries Inc.’s motion for the live testimony of an expert, even as it acknowledged that his credibility was at issue.
As one of the key phrases in both the pre- and post-AIA versions of § 102, what constitutes a prior art “printed publication” is a significant question in many patent validity challenges. The Federal Circuit has wrestled with the question since the court was created in 1982. However, despite its much shorter history, the PTAB likely has issued more decisions addressing this question than any other forum. Given the volume of guidance from the PTAB, petitioners who ignore what the PTAB thinks a printed publication is do so at their own peril.
