Patent Application Information Retrieval

Patent Application Information Retrieval (PAIR) is an online service provided by the United States Patent and Trademark Office to allow users to see the prosecution histories of United States patents and patent applications and obtain copies of documents filed therein. There are two services: Public PAIR, which allows the general public to access information regarding patents and published applications; and Private PAIR, which allows authorized persons to access information regarding applications regardless of publication status.[1]

When a patent application is accessed through PAIR, the following tabs are displayed:

  • Select New Case, to go to a different patent or application
  • Application Data (default), showing bibliographic data about the application
  • Transaction History, showing a list of transactions in the prosecution history
  • Image File Wrapper, from which PDF copies of documents in the prosecution history may be downloaded
  • Continuity Data
  • Foreign Priority
  • Published documents, identifying the patent application publication and patent, if any
  • Address & Attorney/Agent, showing contact information
  • Assignments
  • Display References

Public PAIR

Anyone may use Public PAIR to access the prosecution histories of patents and of those applications that have been published. Unpublished applications are unavailable through Public PAIR. To access Public PAIR, one must verify through a reCAPTCHA process that one is not a robot.[2]

Private PAIR

Users may use Private PAIR to access the prosecution histories of patents, published applications, and those unpublished applications that they are authorized to see. Private PAIR is accessible to registered patent attorneys and agents (and those working under their supervision) who have customer numbers and PKI certificates to secure communication with the USPTO.[1]
