The change affects the filing channel used for outbound international trademark applications from the United States. It does not apply to every trademark filing handled by the USPTO. During the transition, applicants can continue using the agency’s Trademark Electronic Application System, known as TEAS, or begin using Madrid e-Filing.

How the transition will work

Sept. 30, 2026, will be the last day of the interim period. Through that date, TEAS remains available for the affected initial international applications, while Madrid e-Filing is available as an alternative.

Beginning Oct. 1, Madrid e-Filing will be the sole platform for those new international applications. Applicants who use the platform must create an account with WIPO before filing.

The transition therefore creates a preparation deadline for U.S. businesses, trademark owners and the staff or filing systems that handle their international applications. Organizations that continue to use TEAS during the interim period will need to move those procedures to Madrid e-Filing before the October change takes effect.

The USPTO said the new platform is intended to reduce filing errors and improve secure communications while the agency certifies applications. The announcement does not describe a change to the underlying eligibility requirements or substantive registration standards for trademarks; it addresses how the affected applications are submitted and communicated during the certification process.

Final rule accompanies platform change

The platform transition is accompanied by a final rule issued by the USPTO. The agency’s 2026 Federal Register notice list identifies a July 15 final rule concerning electronic filing systems for Madrid Protocol filings.

The rule replaces references to specific electronic filing systems with more general terminology. That change allows the governing language to accommodate the move from a filing process tied to TEAS to one using Madrid e-Filing.

The rule and the platform announcement address applications sent from the United States into the international trademark system. They do not themselves grant trademark protection in other countries. The filing system is part of the process for seeking international protection; protection in any particular jurisdiction remains distinct from the U.S. submission process.

For applicants, the immediate steps are to determine whether planned filings fall within the affected category, establish a WIPO account if Madrid e-Filing will be used, and adjust internal filing procedures ahead of the deadline. The transition also gives current TEAS users time to become familiar with the new platform before its use becomes mandatory.

The next key dates are Sept. 30, 2026, the final day of the interim period, and Oct. 1, 2026, when Madrid e-Filing becomes the required platform for initial international trademark applications based on U.S. applications or registrations.

The USPTO announced the transition July 15, 2026. Beginning October 1, 2026, Madrid e-Filing is scheduled to become the sole platform for initial international trademark applications based on U.S. applications and registrations.

The change applies to U.S.-based international trademark filings handled by the USPTO, affecting applicants nationwide. Businesses seeking trademark protection abroad will need to adjust their filing procedures before the October deadline.

What changes on October 1

After the effective date, applicants will no longer use TEAS for the new outbound international trademark applications covered by the transition. They will instead submit those applications through Madrid e-Filing, a system operated by WIPO.

The shift concerns the route used to submit specified new international applications. The announcement identifies the affected filings as initial applications based on U.S. applications and registrations; it does not describe a broader change to every trademark-related filing handled by the agency.

Madrid e-Filing is part of the Madrid system used by intellectual-property offices in more than 40 countries. For U.S. applicants, the platform provides an electronic path for seeking trademark protection across national borders while the USPTO continues handling the U.S. side of the filing process described in the announcement.

Why the USPTO says it is making the move

The USPTO says Madrid e-Filing is designed to reduce filing errors and provide secure communications when corrections are needed during certification. The agency also says the change may reduce formal certification denials and related petitions.

Those goals matter to companies and legal professionals that regularly file trademark applications for markets outside the United States. A filing error or certification problem can require additional corrective work before an international application can proceed. The agency’s stated rationale focuses on making that part of the process more reliable and improving communication about corrections.

The transition may also change the routine work of trademark practitioners, including how they prepare submissions, monitor communications and respond to certification issues. The approved announcement, however, does not include an estimate of transition costs for applicants or law firms.

What remains unresolved

The packet does not establish whether applications already filed through TEAS must be resubmitted. That leaves an open question for businesses and practitioners with international trademark matters already in progress as the October 1 deadline approaches.

The USPTO’s announcement describes expected improvements to the filing platform, including fewer errors and better correction communications. It does not guarantee that every international trademark application will be processed faster.

For now, the confirmed development is procedural: the USPTO plans to replace TEAS with Madrid e-Filing as the required platform for the specified new international applications based on U.S. applications and registrations. The next known milestone is October 1, 2026, when Madrid e-Filing is scheduled to become the sole route for those filings.

Applicants and trademark practitioners will need to prepare for that platform change while awaiting further guidance on transition costs and the treatment of applications already submitted through TEAS.
