USPTO Alert

Access to USPTO systems 

The U.S. Patent and Trademark Office (USPTO) experienced a Distributed Denial of Service (DDOS) attack impacting the accessibility of our systems. Though all our systems remained online, many external customers and employees experienced interruptions of service. Our teams have worked diligently to address the impact of the attack, and all of our systems, including Patent Center, Trademark Systems, MyUSPTO, and other USPTO-specific services are now fully accessible.

We are continuing to investigate this issue and reviewing additional ways to help prevent it in the future. We appreciate your patience and apologize for any inconvenience.
