Supported Operating Systems (OS), Browser, and JRE/JVM version combinations
|Operating Systems||Web Browsers||Java Runtime Version|
* The Microsoft Edge internet browser is not currently supported. For users of Windows 10, please contact the Patent Electronic Business Center (PEBC) for assistance with alternative browser options.
(link is external)** Google Chrome ended their support for Java plug-ins with versions 45. Therefore, Chrome users with version 45 and above will no longer be able to log into EFS-Web or Private PAIR. Oracle is recommending the use of alternative browsers such as Firefox, Internet Explorer, and Safari. For additional information regarding Java and Chrome please visit https://java.com/en/download/faq/chrome.xml(link is external)
Although the above browsers should continue to work with EFS-Web and Private PAIR, there is always a possibility that these providers may decide to discontinue support of Java plug-ins as well. The USPTO is closely monitoring for any changes, and is committed to keep the IP Community informed accordingly.
Furthermore, the USPTO is investigating if there are possible strategies to mitigate the impact. The Agency is working on a longer term plan to improve the overall authentication process. For USPTO updates regarding this issue please visit either of our Announcements pages:

Please note that each browser version (major and minor releases) may have specific issues that USPTO cannot always address. If you install a later browser version, please be sure to maintain one of the supported browsers in order to ensure access to EFS‐Web. Additional browsers and Java versions are not supported. However, a workaround may be available. Please contact the Patent EBC for general support.
