PAIR Enhancement: Display References

The USPTO has enhanced its PAIR system (Patent Application Information Retrieval) by adding a tab for cited references under which is listed all references cited by the examiner and application, including patents and NPL (non-patent literature) documents. Cited US and foreign patent documents may be downloaded but not NPL (for copyright reasons).

Public PAIR Verification System

The USPTO has implemented a new verification system for users accessing Public PAIR (Patent Application Information Retrieval). Users must now enter a two-word verification code in order to access the system. The system is meant to block bots and spiders. Launched in mid-2003, Public PAIR contains bibliographic data, legal status and prosecution history information and facsimilie images of file wrapper documents for published applications and issued patents.
