On July 15, 2026, the U.S. Patent and Trademark Office (USPTO) published a final rule in the Federal Register amending 37 CFR Part 7 — the rules governing correspondence related to international applications originating in the United States under the Madrid Protocol (the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks).
What changed?
The rule replaces the specific USPTO system names "Trademark Electronic Application System" and its acronym "TEAS" with the generic terminology "trademark electronic filing system," defined as the electronic filing system designated by the Director. The affected provisions are §§ 7.1, 7.4, 7.6, 7.7, 7.11, and 7.21.
Key points for applicants
· Effective date: July 15, 2026 (same day as publication).
· Scope: Madrid Protocol-related filings and correspondence; it does not affect the underlying substantive requirements.
· No substantive impact: The USPTO states the amendment clarifies terminology without changing statutory obligations under 15 U.S.C. 1141–1141c or the filing requirements of 37 CFR Part 7, nor the substantive criteria for international trademark registration.
· Practical takeaway: Filing routes remain unchanged (electronic filing is still required, with a paper petition option only if the electronic system is unavailable). The change reflects USPTO's broader effort to modernize and technology-neutralize its trademark e-filing framework (TEAS → Trademark Center roadmap).
Recommendation: Applicants and their representatives should update internal standard operating procedures, automated filing scripts, and client guidance that still reference "TEAS" so they align with current rule text.
