Oil States Energy Services, LLC v. Greene's Energy Group, LLC
Facts
The America Invents Act authorizes the PTO to conduct inter partes review, a process in which the Patent Trial and Appeal Board may reconsider and cancel issued patent claims on certain prior-art grounds. Oil States owned a patent relating to protecting wellhead equipment used in hydraulic fracturing and sued Greene's Energy for infringement in federal district court. Greene's Energy both challenged validity in court and petitioned for inter partes review, and the Board instituted review after finding a reasonable likelihood that Greene's Energy would prevail. Although the district court issued a claim-construction order favoring Oil States, the Board later concluded the challenged claims were unpatentable, prompting Oil States' constitutional challenge.
Issue
Does inter partes review, which allows the PTO to reconsider and cancel already-issued patent claims, violate Article III by assigning the revocation of patent rights to a non-Article III tribunal? If not, does the procedure nonetheless violate the Seventh Amendment by denying a jury trial?
Rule
Inter partes review does not violate Article III when Congress assigns to the PTO the reconsideration of an issued patent because the grant of a patent is a matter involving public rights and inter partes review is simply a reconsideration of that grant. When Congress properly assigns such a matter to a non-Article III tribunal, the Seventh Amendment poses no independent bar to adjudication without a jury.
