Short Summary
The PTAB denied a Patent Owner's request for Director Review, instead remanding the IPR cases to allow discovery on complex real parties in interest (RPI) and privity issues related to concurrent district court litigation.
Detailed Summary
In this decision, the Board of Patent Appeals and Interferences denied Birchtech Corp.'s requests for Director Review concerning several IPR proceedings. The core dispute centered on whether the Petitioners met the statutory time bar requirements under 35 U.S.C. § 315(b). While the initial Board decisions found the evidence regarding RPI status ambiguous, the Board ultimately remanded the cases with instructions to permit additional discovery specifically aimed at clarifying these relationships before determining if the petitions are timely.
