In such cases, it is essential to get an overview of the activities of specific patent applicants. The value of the analysis will, however, depend very much on the quality of the patent data available, in particular the
Patent data suppliers and patent offices are applying a number of different measures to improve the quality of applicant data. The EPO, for example, has standardised most of the applicant names in its DOCDB database. And, since 2011, the applicant names in its PATSTAT database have been harmonised, and further information added, by the Catholic University of Leuven. These harmonised data are available free of charge (further information is available at https://www.ecoom.be/en/EEE-PPAT).
In addition to these activities, the EPO is engaged within its means in providing high-quality address data in PATSTAT. However, these efforts can only be successful if certain conditions are met for address data from a specific patent authority:
- High-quality address data is delivered to the EPO by the competent patent authority.
- The address data is fed into the DOCDB database, on which PATSTAT is generally based.
- The publication of the address data is consistent with the data protection guidelines.
For other application authorities, the coverage may be less complete. To provide an example: For applications filed with the Japanese Patent Office, the country of residence is available for less than 5 per cent of the applicants and inventors. Address data for these applications is generally not available in the current PATSTAT edition.
Reflecting its quality and service orientation, the EPO is constantly aiming to improve the coverage and quality of the address data in PATSTAT. In this context, we suggest to follow the data coverage of future PATSTAT editions.
