Short Summary
The Director denied the Patent Owner's request for review, remanding multiple IPR cases to allow discovery on complex RPI and privity issues related to time-bar defenses.
Detailed Summary
In this Order, the Director of the USPTO denied Birchtech Corp.'s requests for Director Review concerning several IPR proceedings. The Patent Owner contended that the Petitioners' real parties in interest (RPI) were served with a complaint in Delaware litigation more than one year before the petitions were filed, arguing they should be time-barred under 35 U.S.C. § 315(b). The Director disagreed with the Board’s initial finding of insufficiency and ordered the cases remanded to allow narrowly tailored discovery to resolve the RPI and privity relationships.
