FILE DESCRIPTION
The Patents Citation Index (PCI - File 342), produced by
Thomson Reuters (Scientific), provides access to 54.5
million patent and literature citations found in 7.8 million
patent families. In each update, Examiner citations from
about
50,000
documents
from
major
patent-issuing
authorities are added to the file.
Each record in the database describes a patent family for a
single invention. The patent family data corresponds to the
patent family data provided in Derwent World Patents Index
(DWPI - Files 350,351,352) at the time that the most recent
citations were added to the database.
The PCI record provides a view of retrospective technology
for an invention (cited patents and literature references) and
its impact on subsequent technology (citing patents).
Citations referenced by examiners or inventors in patent
documents are called "cited" patents or literature references
in the PCI record and correspond to the search reports that
accompany patent publications. When a citation references
older inventions/patents, it is also added to the family record
as a "citing" patent.
Examiner citations are provided for family members added
to the file from the following patent-issuing authorities:
Belgium (BE), European Patent Office (EP), France (FR),
Germany (DE), Japan (JP), Netherlands (NL), Spain (ES),
United Kingdom (GB), United States (US), and WIPO/PCT
(WO).
Inventor citations are also included for the time period, May
1994 - May 1997. For this same time period, examiner
citations from Austria, Australia, Canada, Netherlands, New
Zealand, South Africa, Sweden, and Switzerland are also
included. This data remains in the file and is searchable.
Since PCI contains limited information about the patent
family, the DWPI accession number can be used in DWPI
(Files 350,351,352) to obtain detailed information, such as
abstracts, about cited and citing patents as well as family
members. Various MAP command options allow easy
transfer of DWPI accession numbers and patent numbers
between the files.
SUBJECT COVERAGE
PCI
covers all patentable technology with emphasis in three
broad areas: chemical, engineering, and electronic/electrical.
