USPTO: Public PAIR to be Retired

WASHINGTON – The US Patent and Trademark Office (USPTO) announced that it fully replaced the legacy Public Patent Application Information Retrieval (Public PAIR) tool for the electronic filing and management of patent applications. The Public PAIR tool, first launched in the early 2000s, has been officially retired on July 31, 2022.

Since its initial launch five years ago, the newer system has undergone rigorous user testing and iterative improvements, based largely on the public’s input. USPTO will continue to use the feedback received from stakeholder listening sessions, Patent Center training programs, and other events to further refine Patent Center to meet users’ needs.
