Patent Agent Privilege Recognized In Final Rulemaking Issued By USPTO

On November 7, 2017, the USPTO issued a Final Rule recognizing that communications between U.S. and foreign patent practitioners and their clients that are reasonably necessary and incident to the scope of the patent practitioners' authority shall receive the same protections of privilege under Federal Law as if the communication were between a client and a U.S. attorney. 82 Fed. Reg. 51570-75 (Nov. 7, 2017). The privilege extends to communications during all aspects of USPTO practice, including traditional prosecution as well as PTAB proceedings. See 82 Fed. Reg. at 51571 ("the purpose of the rule is to protect any communication with authorized counsel from discovery in PTAB, not just communication about the instant proceedings"). The final rule is effective December 7, 2017.
