By Thomas L. Duston on Posted in Discovery, Inter Partes Review, IPR, Trial Procedures
In a bit of “inside baseball,” the PTAB recently clarified the difference between supplemental evidence and supplemental information.  Practitioners would do well to give careful attention to this distinction.  The difference can have profound consequences to an IPR Petitioner.
