Patent Status

How do you find the status of a patent?

Do you occasionally need to know the patent status of a competitor patent? Sometimes you can - sometimes not. Let's talk about the possibilities.

The first concept to understand is the confidentiality of patent application information. Although there are a few exceptions (there are always exceptions) the general rule under 35 U.S.C. 122 is that patent applications remain confidential until 18 months after filing - at which point they are published. You can read about patent publication here.

All right -what are the exceptions? An application will not be published if it is:

And patent applications that have not been published under 35 U.S.C. 122 are generally preserved in confidence.

The PAIR System

But if a patent application has been published there is a free source of information. This is the Patent Application Information Retrieval (PAIR) system on the U.S. Patent and Trademark Office (USPTO) website.

PAIR displays information regarding patent application status. There is a Public and Private side to PAIR. “ Public PAIR ” only displays issued or published application status. To access Public PAIR, you need only have a patent, application, or publication number that you wish to search.

There is a “Private PAIR”, but it is available primarily to patent agents and attorneys and then only to applications to which they are approved. Private PAIR provides secure real-time access to pending application status and history using digital certificates issued from the USPTO's Public Key Infrastructure.

What does Public PAIR provide?

Public PAIR is available to the public (meaning you). It provides:

    Application Number:

    Filing Date:

    Current Status:

    Application Type:

    Status Date:

    Examiner Name:

    Group Art Unit:

    Earliest Publication No:

    Attorney Docket Number:

    Earliest Publication Date:

    Class / Subclass:

    Patent Number:

    First Named Inventor:

Furthermore it provides a complete transaction history of the application from the original filing and allows you to download all of the communications between the applicant and the examiner.

Pretty comprehensive. If you have an application pending and it has been published you can follow the patent status yourself and follow how your patent agent or attorney is doing in his/her battles with the examiner.
