Key players: USPTO (led by Director Squires), patent owners, and third-party requesters; no specific companies or legislation named, though the procedure addresses procedures under 35 U.S.C. §§ 302-304.[1][7][8][11] Ex parte reexamination filings have surged since 2025 USPTO policies reduced inter partes review (IPR) institutions at the Patent Trial and Appeal Board, making ex parte a preferred patent challenge outside courts due to no discretionary denials (e.g., Fintiv factors), no estoppel under § 315(e), and a lighter SNQ standard.[1][2][5][6][7]
Timeline and context: Traditional ex parte process (over 40 years old) evaluated requests solely on requester's submission for SNQ before ordering reexam; owners responded only post-order.[1][3][11] IPR/PGR decline since 2025 drove ex parte requests above IPR/PGR levels, prompting USPTO to aid examiners' 3-month SNQ timeline with owner input.[1][2][6] This experimental procedure signals potential future rulemaking if effective.[7]
Newsworthy now: Announced April 1 and effective April 5, 2026—just days before current date—it equips patent owners with an early defense tool amid rising ex parte challenges, potentially blocking reexams at the threshold and reshaping strategy versus full proceedings.[1][2][4][7] Practitioners view it as a "modest win" for owners, though outcomes depend on uptake.[4][7]
