USPTO Systems Will Be Down at Times During Late April to Late July - USPTO systems will be unavailable at certain times on week ends between April 29 and the end of July for the move of the USPTO Data Center from Crystal City to Alexandria.

The move of the USPTO Data Center, the backbone of automated services such as the Order Entry Management System (OEMS), Patent Application Information Retrieval (PAIR), Revenue Accounting and Management (RAM), and Trademark Electronic Application System (TEAS), will be done from 6pm Fridays to 5:30 am Mondays to minimize disruption to employees and the public. On Memorial Day weekend and the Fourth of July work will continue until 5:30 am on the Tuesday following those Monday holidays.

During the weekend hours of the move, many systems may be unavailable. Automated search service options available through the Public Search Facility and Patent and Trademark Depository Libraries (PTDLs) will also be affected by the upcoming moves. In addition, online and telephone assistance available through the USPTO Contact Center and Patent Electronic Business Center may be reduced during move periods.

A consolidated schedule of planned outages is posted on the Internet Outage Schedule. Please note that the posted schedule reflects current estimates. The schedule is expected to change during the project.
