PALM Maintenance Update

Statement updated at 7 a.m. ET August 21, 2018

As we reported earlier today, experts in databases, operating systems, and storage from within the USPTO and from our external vendors are working around the clock to restore the PALM database. They have made significant progress, and our best estimate is still that service will be restored sometime tomorrow. Please note, there are many factors involved in this process and the status can change between now and then. We are focused on complete and accurate restoration of service as quickly as possible.

In the meantime, we continue to receive and accept filings and payments through alternative means, and our Patents employees have continued to work throughout this outage—including those in our Patents Electronic Business Center who can assist customers, from 6 a.m. to midnight ET, with filing their electronic patent application submissions via EFS-Web and EFS-Web Contingency. EFS-Web Contingency is able to accept the following new applications: Nonprovisional Application under 35 USC 111(a), Provisional, Reexam, Reissue, Design, PCT, and Hague. Please note that National Stage submissions under 35 U.S.C. 371, Supplemental Examination, ePetition to make special based on age (37 CFR 1.102), ePetition to Accept Unintentional Delayed Payment of the Maintenance Fee (37 CFR 1.378(b)), Third-Party Preissuance Submission under 37 CFR 1.290, and Prior Art Submission into a Patent File under 37 CFR 1.501 must be filed through an alternative filing method. Given the availability of 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 share them on this page. In the meantime, applicants should continue to file and pay associated fees pursuant to current laws and regulations.

Systems not highlighted below, such as all those associated with Trademarks continue to function as normal. We remind you that you may be able to access and use some of the highlighted systems below, but please note that the data in those systems is only valid up to Wednesday, August 15 at 12:01 a.m. ET.

Because the PALM database is down, the following systems are currently unavailable:

  • Electronic Filing System (EFS-Web)
  • Electronic Freedom of Information Act (E-FOIA)
  • Electronic Patent Assignment System (ePAS)
  • Employee Locator Search
  • 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)
  • Patent Maintenance Fees Storefront
  • 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.

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.

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