PALM Maintenance Update

Statement update at 4:00 p.m. August 21, 2018

As we reported on August 20, experts in databases, operating systems, and storage from within the USPTO and from our external vendors have been working around the clock to restore the PALM database. They have made significant progress, and systems began returning to service this morning. Please keep an eye on the bullets below for status of specific systems.

While systems have been coming back online throughout the day, we intend to take them out of service beginning at 10:00 p.m. ET tonight. Our onsite experts will be working throughout the night to further optimize system performance. We anticipate that the systems will be back online tomorrow morning.

We will continue to receive and accept filings and payments through alternative means during this outage. EFS-Web Contingency is available as an option when the primary portal for EFS-Web is unavailable. Given the availability of the alternative filing methods, the USPTO does not plan to extend deadlines.

Applicants affected by this outage will have an option to avoid, or receive a refund of, paper filing fees. 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.

Our Patents employees continue to work. Systems not highlighted below are functioning as normal. We remind you that you may be able to access and use some of the highlighted systems below, but please note that if a system that is noted below is accessible to you, the data in that system may only be valid up to Wednesday, August 15 at 12:01 a.m. ET.

While we continue to complete the accurate restoration of all services, the following systems are not yet fully functional:

  • Electronic Freedom of Information Act (E-FOIA)
  • Electronic Patent Assignment System (ePAS)
  • Global Dossier (GD)
  • Office of Enrollment and Discipline Information System (OEDIS)
  • Order Entry Management System (OEMS)
  • One Portal Dossier (OPD)
  • Patent Global Dossier Public Access Dossier (P-GD-PAD)
  • 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. At a minimum, you will see updates at 10 a.m. and 4 p.m. daily until service is fully restored.

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