The first decision issued by the new USPTO Precedential Opinion Panel (POP) tackled the difficult issues of statutory interpretation of sections 35 U.S.C. § 315(b) and 35 U.S.C. § 315(c). In sum, the Board determined that both same party and issue joinder is proper in inter partes reviews (IPRs). The Board also determined that otherwise time-barred petitions are proper when accompanied by a joinder request to a pending IPR. The Board interpreted the statute in a manner to maintain broad discretion for the Agency. The POP could have properly interpreted Section 315(c) by first focusing on the statutory language “join as a party” as being limited to any person not already a party. Instead, the decision dismissed this viewpoint and stated that “the statutory phrase ‘any person’ broadly applies to the phrase ‘join as a party’.” Although I disagree with the emphasis on “any person,” I anticipate that the Board’s reasoning on both same party and issue joinder would be upheld as proper statutory interpretations by the Federal Circuit, if appealed.
