Whether inter partes review, through which the PTO may reconsider and cancel issued patent claims, violates Article III by assigning judicial power to a non-Article III tribunal.
Holding
No. Inter partes review concerns a public right—the reconsideration of the Government's grant of a patent franchise—and Congress may assign that matter to the PTO.
Reasoning
Article III generally vests the federal judicial power in courts whose judges have life tenure and salary protection. But the Court's precedents permit Congress substantial latitude to assign adjudication of “public rights” to legislative or executive bodies. Although the Court has not supplied a single exhaustive definition of public rights, the doctrine covers matters arising between the Government and persons subject to its authority in carrying out legislative or executive functions.
A patent's original grant is a public-rights matter. Patents are government-created public franchises: the Government removes certain knowledge from the public domain and grants the patentee a statutory right to exclude others. That right did not exist at common law, and Congress, exercising its Patent Clause authority, has long authorized executive officials to decide whether an applicant meets the statutory conditions for receiving it.
Inter partes review addresses the same basic matter as the original grant. It is a second administrative examination of whether a claim satisfied the statutory novelty and nonobviousness requirements, and it protects the public's interest in ensuring that patent monopolies do not exceed their legitimate scope. The fact that review occurs after issuance does not change the analysis because patents issue subject to the statutory possibility of PTO reconsideration and cancellation.
The Court rejected Oil States' reliance on older cases describing issued patents as the patentee's private property and stating that only courts could annul patents. Those decisions arose under the Patent Act of 1870, which lacked any post-issuance administrative-review mechanism. They described the authority Congress had then granted to the Patent Office, not a constitutional bar against Congress later creating inter partes review. A patent remains property, but it is property defined and qualified by the Patent Act's provisions, including inter partes review.
History did not establish that patent validity, by its nature, must always be decided in an Article III court. Eighteenth-century English defendants could contest validity in infringement litigation and parties could use scire facias proceedings, but they also could petition the Privy Council—an executive body—to revoke a patent. Because the Patent Clause was adopted against that background, Congress could permissibly provide that a patent grant is subject to administrative cancellation.
The Court also declined to treat inter partes review as unconstitutional merely because it resembles litigation. Discovery, evidence, adversarial hearings, administrative patent judges, and binding final decisions do not create a “looks like” test for Article III judicial power. The Board does not determine Greene's Energy's liability to Oil States; it reconsiders the Government's own patent grant. The Court stressed that its ruling was narrow: it did not decide whether infringement suits or other patent disputes may be assigned outside Article III courts, nor did it decide due-process, takings, or retroactivity questions not raised by Oil States.
