Advanced Techniques for Statistical Analyses in INPADOC on STN

The two INPADOC files on STN, INPADOCDB and INPAFAMDB, offer a great variety of patent analysis options. While INPADOCDB provides an optimized environment for application-based patent statistics, the patent family database INPAFAMDB supports statistics looking at the number of inventions. This presentation exemplifies techniques to perform statistical analysis in both databases and answers fundamental questions like “which parameters to choose for which patent analysis”. Examples also illustrate how legal status information could help in statistical analysis. Typical questions are:

  • Which are the top companies in a certain technology area?
  • How do the filing activities of the top companies compare in major patent countries?
  • How can I determine the grant rate in major patent countries?
  • How long does company A maintain patent protection in particular countries?
  • How innovative is company A in comparison with company B over the last ten years?
  • Who is opposing patents of company A and whose patents are company A opposing?

This intermediate session will be of interest to new and experienced STN searchers, providing a variety of tips and advice for effective patent analysis in the INPADOC files on STN.
