TEAS 6.0 and TEASi 3.0 release highlights

We are upgrading the backend infrastructure of the Trademark Electronic Application System (TEAS) and the Trademark Electronic Application System International (TEASi) to improve the operational efficiency and stability of these systems. In addition to the upgrade, we made a few minor enhancements and bug fixes, which are listed below.

  • USPTO standard website headers and footers have been incorporated into all application forms, to provide a more consistent look and feel across all USPTO systems.
  • Text entered in the free-text field of the global forms will no longer disappear when you navigate away from the page.
  • For those filing under the Madrid Protocol, when you’re completing the application for international registration and subsequent designation forms, you can now select all countries for subsequent designation.
  • Issue with the collective membership mark form that was affecting the method of control statement has been fixed. Your statement will now appear correctly in Trademark Status and Document Retrieval (TSDR).

The release will occur on Saturday, December 15, 2018 at 8 a.m.

You must file all saved forms and e-signature forms by 7:30 a.m. ET on Saturday, December 15. If you don’t file these forms by that time, you will have to start the process again with the new forms. We apologize for any inconvenience.

For questions about this release, please email TEAS@uspto.gov.

What do I need to do now that the upgrade is complete?

Postal code requirements for international filers

Applicants and registrants in many countries must now provide a postal code in the address fields. This enhancement, based on a United States Postal Service (USPS) requirement, helps us make sure USPTO mail reaches you. See the USPS’ countries that require postal codes table(link is external) for formatting foreign postal codes.
