As of July 9 2010, the coverage of patent citation data in the INPADOC files INPADOCDB and INPAFAMDB has been enhanced. The recent enhancements comprise new citation details and improved functionality supporting new and efficient ways for competitor analyses:
- publication dates available for cited patent numbers
- improved coverage of applicant citations
- sources of citation extended for PCT-applications
- search report office available for citations of PCT-applications
- cited patent assignee names are now searchable
Patent Citations are very useful sources to find additional prior art, to identify key patents of a particular area of technology and to see if a company is driven by innovative technologies.
The INPADOC databases cover patent citations for more than 12 mio applications from 21 patent authorities. These citations are a valuable source for analyzing the prior art provided by patent applicants and patent examiners.
Cited patent numbers enhanced with publication dates and improved coverage of applicant citations
Cited patent numbers are provided with their respective publication dates for all documents which are new or have been updated since March 2010. This new information is associated with two new search and select fields: the cited patent publication date RPD (=PD.D) and the cited patent publication year RPY (=PY.D). The publication dates of cited patents indicate to which extend a company cites relatively recent patents and is thus more innovative than a company whose patents cite older patents.
The coverage of applicant citations for EP- and PCT-publications has been extended to cited applications numbers. These cited application numbers refer to
- patent applications followed by a patent publication: instead of the application number we cite the publication number in the field REP and indicate this with an asterisk *.
- pending applications (not yet published)
- US provisional applications (no publication)
- applications abondoned (no publication)
Referenced application information is searchable via the new search fields AP.D, AC.D and AK.D, the corresponding display format is the REAI-format.
In the course of implementing the new citation data, various synonym field names have been introduced to be more consistent with the Patent Citation Index (PCI).
