Problems Viewing USPTO Web Pages with Older Web Browsers

If you are using an older version of a Web browser, you may experience slow response or script errors when viewing pages on www.uspto.gov.

USPTO is continuing to work towards a resolution. In the meantime, your use of a newer browser should significantly improve performance.
