      Citation Searching

      Citations are a list of references appearing in a patent that refer to relevant prior art.

      Both forward and backward citations can be searched in Quartet.

      • A forward citation search retrieves records that are citing the patent(s) of interest.
      • A backward citation search retrieves previously published records that are cited by the patent(s) of interest.

      Citations can be searched on DOCDB family level by using the CIT command, and on domestic family level by using the PUBCIT command.

      The above commands will search both forward and backward citations.

      Modifiers can be included to search only forward or only backward citations. Additionally, modifiers can be included to search only citations from the specified category.
