USPTO Systems Status and Availability

Wednesday Dec 23, 2015

Power Outage

A major power outage at USPTO headquarters occurred last night resulting in damaged equipment that required the subsequent shutdown of many of our online and IT systems. This includes our filing, searching, and payment systems, as well as the systems our examiners across the country use. We are working diligently to assess the operational impact on all our systems and to determine how soon they can be safely brought back into service. Status updates will be issued on this page as they become available, as well as on our Facebook ( and Twitter (

Thank you for your patience as we work to restore full service as soon as possible.


TEAS and TEASi are currently not available. If your submission is time sensitive or If you have a filing due today and the document cannot be filed via TEAS, you must use an alternative method of filing to ensure that the document is timely received by the USPTO.
