Detailed Summary

This Order supplements a prior Director Review Decision concerning several Inter Partes Reviews (IPRs) challenging various patents. The review addressed issues of Real Party in Interest (RPI) and privity, specifically focusing on the permissibility of multiple petitions against the same patent. Citing a precedent set in PacifiCorp, the Director instructed the Board to maintain at most one IPR for each challenged patent if petitioners successfully demonstrate they have identified all RPIs.
