Realtek Semiconductor Corp. v. ParkerVision, Inc.

When a petitioner is time-barred under 35 U.S.C. § 315(b) because it filed after the one-year period from service of the complaint, the Office may consider the fairness of letting it join an ongoing proceeding in deciding whether to deny institution under 35 U.S.C. § 314(a). That is so even though § 315(b) permits a time-barred party to file a petition seeking joinder under § 315(c). Petitions filed by time-barred parties should proceed only in exceptional circumstances. No prior precedent directly addressed this issue; the decision cites no earlier Board decision. A petitioner served with a complaint more than a year earlier can no longer rely on the § 315(b) joinder exception alone for a copycat petition and joinder motion. It must show an exceptional circumstance or risk discretionary denial under § 314(a). A patent owner can oppose a time-barred joinder petition with fairness and equity arguments, and here that request succeeded and both petitions were denied. The decision cites no Federal Circuit, CCPA or Supreme Court authority; it relies only on 35 U.S.C. §§ 314(a), 315(b) and 315(c). LEGAL TEST OR STANDARD: Discretion under 35 U.S.C. § 314(a) is exercised on a holistic assessment of all evidence and arguments presented. The Office may consider whether it is fair to permit a time-barred party to join an ongoing proceeding. Petitions filed by time-barred parties should proceed only in exceptional circumstances. The decision lists no numbered factors. TRIGGERING FACTS: ParkerVision served its infringement complaint on Realtek on September 28, 2023. TI petitioned on May 18, 2024 and its petition was instituted November 26, 2024. NXP's copycat petition and joinder request were granted December 19, 2024. Realtek filed its copycat petition and motion to join the TI proceeding on December 24, 2024, after its § 315(b) deadline expired on September 28, 2024, and showed no exceptional circumstance. KEY QUOTE: "Petitions filed by time-barred parties should proceed only in exceptional circumstances." (Paper 11, p. 3) PRIOR PRECEDENT AFFECTED: No prior precedential or informative decision is directly affected. PRACTICE TIP: If you are time-barred under § 315(b) and plan a copycat petition with a joinder motion, put the exceptional circumstances in the petition and in any opposition to discretionary denial. Do not rely on § 315(b)'s joinder exception alone.
