The First Office Action Estimator is currently unavailable.
In fiscal year 2021, the USPTO moved to a new methodology for assigning applications to examiners. We are currently in the process of updating the first action estimator to align with the new routing/docketing system. During the update period this estimator as well as the version on Private PAIR will be unavailable. We recognize that many of our applicants use this tool and plan to have a working version available as soon as possible.
While we are updating the First Office Action Estimator, you can identify that your application is closer to examination when it is assigned to a specific examiner in a specific art unit. Upon assignment, examination will begin within approximately two months.

First Office Action
An Office action is a document written by a patent examiner in the course of examination of a patent application. The Office action may cite prior art and gives reasons why the examiner has allowed (approved) the applicant's claims, and/or rejected the claims. A first Office action on the merits (FAOM) is typically the first substantive examination of the application.
