Browser Information

TEAS is a web-based application that requires a web browser version at or above that of: Microsoft Internet Explorer (IE) 6.0, FireFox 3.0, Safari 3.0. While the USPTO does not specifically endorse these products; these are the browsers that support various TEAS features, namely, frames, JavaScript, and file upload. TEAS filers should check their web browser settings for SSLv3 and TLSv1. The box labeled "Use SSL 3.0 and TLS 1.0" should be CHECKED and the box labeled "Use SSL 2.0" should be UNCHECKED. See Steps to enable the SSL3 and TLS1 settings. If during the payment process for your filing you encounter an "SSL Certificate Error," you should try a browser other than IE. Or, if limited to IE, please simply try the next available browser version (for example, IE7.0 and IE8.0 are currently available for download). Or, if necessary, please review the information available at SSL Certificate Troubleshooting. If your browser does not meet, or exceed the required standards, you may acquire these web browsers at:
