The United States Patent and Trademark Office (“USPTO”) has announced the availability of an online First Office Action Estimator tool to provide an estimate on when to expect a first Office Action for pending U.S. patent applications.

The estimator has been updated to account for the recent changes to the methodology for assigning patent applications to patent examiners.  In fiscal year 2001, the USPTO transitioned to using the Cooperative Patent Classification (CPC) to assign applications.

While the estimator can provide helpful insight, the estimates are not guaranteed by the USPTO.
