The USPTO will perform a migration on EFS-Web and P-TACTS from the Production Data Center in Alexandria to a new Data Center in Manassas from 12:01 a.m. until 11 a.m. on Saturday, July 29 ET.

The EIDO support team will perform a backup of the data prior to the product component's migration date, and USPTO data will be migrated AS-IS. There will be no application and configuration changes needed. 

Note: The following systems will be unavailable during the migration window:

     EFS-Web for Registered eFilers, Unregistered eFilers, and EFS-Web Contingency

     Patent Center

Please refer to our Filing Documents during an Outage page for other alternative filing method.
