Viewing a Full Patent File or Patent Application File

Where do I view the full patent or patent application file?

To view the full patent or patent application file use USPTO Patent Center.

How do I view the full patent file or patent application file?

1) Go to the USPTO Patent Center, which allows you to view both full patent and patent application files.

2) Enter the:

Application Number
Patent Number, or
Publication Number.

You can find the Application Number, Patent Number, or Publication Number by looking up the patent or patent application using USPTO Public Patent Search, Google Patents, or other databases like Escapenet.

What is the full patent or patent application file?

The full patent or patent application file contains all the documents related to the patent application and elements related to the patent after it is issued.

The full patent file can also be called the prosecution history.

All parts of the file are separated into different tabs on the left side bar of the USPTO Patent Center.

A major part of the full file is called the Document & Transactions, which includes:

Difference between the full patent or patent application file and the patent or published patent

The full patent or patent application file will show all the documents related to the patent application (application, rejections from patent examiners, responses to rejections, etc.).

The patent document will show the final patent which was approved/issued.

The published patent application will show a version of the patent application which may be different than the final approved patent. Patent applications are normally published 18 months after submitted, but the application can change between the time of publication and approval.

The patent or published patent application is found on the USPTO Public Patent Search, Google Patents, or other databases like Escapenet.

The full patent or patent application file is found on USPTO Patent Center.
