<b>BULK DATA:</b> The TSDR Application Programming Interface (API) will be unavailable starting May 7 at 12 a.m. ET for at least two weeks. Bulk data customers who rely on the TSDR API can use <a href="https://www.uspto.gov/trademarks-application-process/checking-application-status-view-documents/trademark-bulk-data">alternative methods</a> to receive bulk data from TSDR. If you are a bulk data customer who has questions or needs additional information, please <a href="mailto:email@example.com">email us</a>.
<b>INTERMITTENT SYSTEM ISSUES:</b> Due to high-volume usage, you may experience intermittent issues on the Trademark Status and Document Retrieval (TSDR) system between 6 – 8 a.m. ET. Refreshing your web browser should resolve the issue. If you still need assistance accessing a document, email <a href="mailto:firstname.lastname@example.org">email@example.com</a> and include your serial number, the document you are looking for, and a screenshot of any error messages you have received.
<b>ENHANCEMENT TO PROTECT YOUR PRIVACY:</b> When applicants and registrants are not represented by an attorney, the USPTO now masks the correspondence email address in the status tab and the Application Programming Interface (API). We made this change to reduce the likelihood that customers will be subjected to scams and unwanted solicitations.
