PAIR (Patent Application Information and Retrieval)
PAIR is the Patent Application Information Retrieval system that displays information regarding patent application status. There is both 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. Private PAIR is the Patent Application Information Retrieval system developed to provide secure access for customers who want to view current patent application status electronically via the Internet.
