Patent Center, EFS-Web, TEAS, and TEASi Intermittent Filing Issues

Users are intermittently receiving a 429 eError code “too many requests” when attempting to log into their USPTO.gov accounts to file in Patent Center, EFS-Web, TEAS and TEASi. The workarounds for this error are clearing the browser cache or switching web browsers.

Other USPTO systems may also be affected. The USPTO technical teams are investigating.
