On Saturday, October 15, 2016, TEAS and TEASi will now use HTTPS (Hypertext Transfer Protocol Secure), the strongest privacy and integrity protection currently available for public web connections. Those accessing web pages formerly found at http://teas.uspto.gov/ will automatically be redirected to the pages' new https location. Many of our systems already use the https protocol, and we continue to work to update all our systems to HTTPS as part of a government-wide effort to ensure all federal websites use HTTPS. Using HTTPS ensures a new, strong baseline of user privacy and security across U.S. government websites and APIs. We expect user impact to be minimal.
TEAS and TEASi will be unavailable for the system upgrade beginning at 8 a.m. ET on October 15th and ending at 4 p.m. ET. For the latest information about the upgrade to https and other changes to our online systems, visit the USPTO system status webpage.
