Multi-Color Corp. v. Brook & Whittle Ltd.

When a petition for post-grant review is filed within the nine-month window of 35 U.S.C. § 321(c), the Board (through the Director's discretionary-denial review) weighs that timing as a factor favoring institution, because PGR petitions are favored as close in time to examination and before expectations in the patent rights are strongly settled. In a holistic assessment, that timing, together with the petitioner not being a party to the parallel district court cases and no trial date being set in one of them, outweighed a Texas trial date that precedes the final written decision date, so discretionary denial was not appropriate. No prior precedent directly addressed this issue in the text, which relies on LifeVac, LLC v. DCSTAR Inc., IPR2025-00454, Paper 11 at 2 (PTAB July 11, 2025), for the point that PGR petitions are favored. A petitioner who files within nine months of grant can cite this decision to argue that timing counts against discretionary denial, even when a district court trial is likely to precede the final written decision. A patent owner cannot rely on a parallel-litigation trial date alone to obtain denial of a PGR, and must address the timing, the petitioner's relationship to the defendants, and the status of the other proceedings. The decision cites 35 U.S.C. § 321(c) and § 325(d) but no Federal Circuit or Supreme Court authority. LEGAL TEST OR STANDARD: No numbered factors are stated. The Director weighed all relevant considerations in a holistic assessment of the totality of the evidence and arguments, balancing the factors for discretionary denial against those counseling against it, and including whether discretionary denial under 35 U.S.C. § 325(d) is appropriate. TRIGGERING FACTS: The challenged patent issued April 16, 2024, and the petition was filed January 16, 2025, nine months from grant. The patent was at issue in an Eastern District of Texas infringement suit, with trial set for May 18, 2026, about four months before the September 21, 2026 final written decision due date. It was also at issue in a District of Delaware declaratory judgment action with no trial date. The petitioner was not a party to either case and represented it had no substantive relationship with any defendant. The petitioner also gave persuasive, evidence-supported reasoning against § 325(d) denial. KEY QUOTE: "Petitions for post-grant review are favored because they must be filed no later than nine months from the grant of the patent (35 U.S.C. § 321(c)), are close in time to examination, and occur before expectations in the patent rights are strongly" (Paper 10, p. 2) PRIOR PRECEDENT AFFECTED: The decision follows LifeVac, LLC v. DCSTAR Inc., IPR2025-00454, Paper 11 at 2 (PTAB July 11, 2025), for the proposition that PGR petitions are favored. No other prior Board precedential or informative decision is named. PRACTICE TIP: A PGR petitioner should stress filing within the nine-month window of § 321(c), its lack of any relationship to the district court defendants, and the status of parallel cases, and should support its § 325(d) arguments with evidence in the opposition to any discretionary denial request. A patent owner should not rest on a trial date that precedes the final written decision.
