Comments on USPTO Disclosure Rule Split Over Who Is Really Behind Anonymous Patent Challenges
A U.S. Patent and Trademark Office proposal to require third-party requesters for ex parte reexamination to name all real parties in interest has drawn a sharply divided response, with the dispute turning on the same transparency questions that animate the broader litigation funding disclosure debate.
As reported by IPWatchdog, 26 comments were filed before the period closed on 21 August, submitted by 17 organisations and eight individuals. The July rulemaking notice proposed that requests identify the requester and any other real parties in interest, with statements kept confidential on request, so the Office can assess whether statutory estoppel provisions bar a filing. The USPTO said it has received a significant number of reexamination requests aimed at patents already challenged in inter partes or post-grant review.
Eight of the 17 organisational comments opposed the rule outright. Supporters included Adeia, Nokia, Dolby Laboratories and the Council for Innovation Promotion. Adeia said it received ten anonymous requests between October 2025 and April 2026 after more than a decade without any, and had to defend its patents without knowing whether the requester was a licensee, competitor, affiliate of an estopped party or a foreign-backed organisation.
Dolby went further, arguing that a requester's own identification may be insufficient and proposing that requesters answer factual questions about their business model, member or subscriber funding, and the source of funds used for the challenge. Nokia recommended additional guidance covering indemnification obligations, industry consortia and third-party funding.
Opponents including the Business Software Alliance, Unified Patents and the PTAB Bar Association argued the Office has produced little evidence that estopped parties are exploiting anonymous reexamination, and warned that importing a fact-intensive real party in interest inquiry into an examiner-driven proceeding without discovery would generate satellite disputes and deter legitimate filings.
