In a recent proceeding at the Patent Trial and Appeal Board (PTAB), the case of Roofr Inc. v. Eagle View Technologies Inc., IPR 2023-00437, took an unexpected turn when the PTAB denied institution of inter partes review of a patent associated with determining the pitch of roofs. This decision was based on the failure of the Petitioner to effectively question the sufficiency of the Patent Owner’s priority assertions.Jones Day reports.
Further strain was placed on the case when the Patent Owner provided evidence that raised doubts about the validity of a prior art reference, the “Kennedy” reference, used by the Petitioner. The Petitioner’s insufficient challenge to this contention added to the issues they faced during the proceedings.
The PTAB’s denial to initiate an inter partes review based on these grounds marks a significant density in the course of patent law proceedings. It emphasises the importance for petitioners to adequately counter the claims of patent owners, especially those concerning the credibility and standing of prior art references.
As such, lawyers who practice in intellectual property law, especially those preparing for patent litigation, should make note of this development. A meticulous and robust approach towards questioning the assertions presented by patent owners can contribute significantly towards the advancement of cases in future patent disputes.
