Viewing Patent Citations
Patent citation viewing options are fairly limited in STN. There is no Citation Mapping or other advanced citation viewing feature.
For data files that contain patent citation information such as USPATFULL and USPAT2, cited documents are searchable and displayable in the Citation (CIT) field. Users can view the Reference Patent Information (REP) and Reference Non-Patent Information (REN) display formats for viewing cited references in USPATFULL, USPAT2, and INPAFAMDB. A Reference (RE) display format is now available in the full-text patent files PCTFULL, FRFULL, GBFULL, and AUPATFULL. If citations are available in the corresponding INPADOCDB record, they are displayable with the command => D RE.
Citation Searching in DPCI
A unique and powerful way to access patent citation information in STN is by searching in the Derwent Patents Citation Index (DPCI).The Patents Citation Index is a unique database of Examiner citations, both patent and literature, appearing in patents and references to citing patents from 1973 to date coming from 23 patenting authorities. This data file, produced by Thomson Reuters, also contains updated bibliographic patent family data as well as value-added fields such as enhanced Titles from the Derwent World Patents Index (DWPI).
A user can obtain a list of documents cited by or citing a particular patent from any of the multiple issuing authorities covered all from this one STN data file.
DPCI is accessible through STN Express and STN on the Web, and users can also search DPCI on STN Easy under the "Patents" or "Patents, Citations" categories.
Citation Searching in STN Easy
In the STN Easy interface the Citation Searching feature may be used to find documents citing the reference that is displayed. Users can select the "Find documents citing this reference" link, found in many STN Easy database records, to search the SCISEARCH and CAplus databases.
Cited References in STN Easy
CAplus records added from 1999 to the present contain a list of references cited in the document. The first five cited references are listed near the end of the display. Users may select the "More References" link to see additional cited references, if available.
Cited references that the system determines to have records in CAplus or MEDLINE are followed by a CAplus or MEDLINE link. If a reference appears in both databases, then only the CAplus link is shown. The user should click the CAplus or MEDLINE link to display the detailed record for the reference. The cost for linking to a cited reference is displayed next to the link.
