An inter partes review (IPR) before the Patent Trial and Appeal Board (PTAB) is a proceeding of the petitioner versus the patent owner. In a situation where the petitioner or the patent owner consists of multiple entities, there may be a question as to which entity may speak for the group. This is the issue that the PTAB addressed in Cradlepoint, Inc. v. 3G Licensing S.A., IPR2021-00639, Paper 12 (May 13, 2021). The PTAB here concluded that the multiple entities must act as a single party, and each paper filed on behalf of “Petitioner” binds all entities.
