Is the U.S. Patent and Trademark Office (PTO) entitled to Chevron deference? Does this matter? Many commentators believe that courts’ failure to grant Chevron deference to the PTO’s interpretations of substantive patent law renders it powerless as a policymaking institution. As previously discussed on this blog, Arti Rai and Melissa Wasserman have argued that the America Invents Act (AIA) changes this by granting adjudicatory or rulemaking authority to the PTO over substantive questions of patent law, including the standards of patentability, and consequently interpretive authority.
