<b>TSDR API DATA:</b> The TSDR Application Programming Interface (API) has limited availability due to system upgrades. We anticipate full return to service for all API users by the end of the month. In the meantime, if you need to retrieve an office action, you can access it directly from the TSDR documents tab located below. We thank you for your patience while we make these improvements.
