PALM Maintenance Update

Statement Update at 10 a.m. August 23, 2018

USPTO’s systems remain operational. You can file your applications electronically through EFS-Web, but if you do you may continue to see a delay in your documents being viewable on our systems. Those who filed by paperwork over the past few days will not see your documents on our systems for 5-10 business days. Our team of experts continues to monitor all of the systems that have been affected by this outage.

As we’ve previously announced, the director will prescribe a procedure for re-submitting applications electronically to receive a refund of the paper filing fee (or to not incur a fee if not yet paid). Applicants who follow this procedure will maintain their original filing dates for applications filed by paper during the outage. Once the details of this procedure are ready, we will post that information on our website. In the meantime, applicants should continue to file and pay associated fees pursuant to current laws and regulations.

As noted in previous updates, the USPTO does not plan to extend deadlines. While we continue to complete the accurate restoration of all services, the following systems are not yet fully functional:

  • Private Patent Application Information Retrieval (Private PAIR)
  • Public Patent Application Information Retrieval (Public PAIR)

We are aware of how this system outage impacts those who have patent-related business with the USPTO and we know you have questions on a variety of topics. We posted answers to some questions we know you have or that you may be wondering about the PALM database issue. We will update those questions and answers after this incident is complete.

Further status updates will be issued on this page ( as they become available. Our next scheduled update will be at 4 p.m. ET today.
