The United States Patent and Trademark Office is sensitive to your concerns regarding the security of using your credit cards to purchase items over the Internet. Safeguarding your privacy and confidentiality is of the utmost importance to us.


The USPTO uses Secure Sockets Layer (SSL) which encrypts your credit card data while it is being transferred. This makes it very difficult for someone to steal your credit card information.


Encryption means that all of your information, including your credit card number, is scrambled and locked with a mathematical key during transfer. Most browsers have an icon such as a key key icon or a lock lock iconto represent an encrypted mode or session. A broken key broken key icon, open lock open lock icon, or no lock indicates that the session or mode is not encrypted.


SSL works with Netscape Navigator (versions 2.0 and above), Microsoft Internet Explorer (version 3.0 and above), and AOL (version 3.0 and above) so that unauthorized parties cannot read the information that you send.


More information regarding a browser's encryption can usually be found in the security information section of the browser's "Help" feature (look for information about encryption). You can also contact Netscape, Microsoft, your system administrator, or your Internet Service Provider for information about the level of encryption on your browser.
