S. 1553: PREVAIL Act

This bill addresses various issues relating to the U.S. Patent and Trademark Office (USPTO), including by imposing additional requirements on administrative patent validity challenges (proceedings to review and potentially cancel issued patents) at the USPTO.

The bill modifies provisions relating to inter partes reviews (IPRs) and other administrative patent validity proceedings, including by

• prohibiting an administrative patent judge who participated in deciding whether to institute an IPR (i.e., whether to allow the IPR to proceed based on the initial petition) from also participating in deciding the final outcome of the same IPR;
• prohibiting a person (individual or entity) from petitioning for an IPR against a patent unless the person meets certain standing requirements (currently, any person may petition for an IPR);
• prohibiting a person who has challenged a patent's validity in an IPR from raising the same challenges against the patent in other proceedings (e.g., district court) if the IPR has been instituted; and
• raising the burden that the petitioner in an IPR must meet to invalidate a previously issued patent claim.
