Citation Search
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.

Running a Citation Search from a record
Citation searches can also be run from the detailed view of a record. From the detailed view, choose the Citations tab in the middle pane. This view shows citations from each document in the family, as well as a filter option for each type of citation, or country code. From here there is a "Run citations search" button.
The button will bring up a dialog box for choosing specifics for the citation search
From here, citation forwards or backwards or both can be chosen, as well as which family members are searched, and the type of citation, A, X, or Y. Additionally the search can be run in the background as with all other modals.
