Update Schedule
Overview
The CLAIMS Global Patent Database data is delivered as a separate record for each patent publication, with data merged from multiple sources. The sources include the following:
- DocDB and legal status from the EPO
- Bibliographic and full text files from national patent offices
- Assignment information for US
- Translated bibliographic data for Japan from Patent Abstracts of Japan
New raw data is loaded as soon as published and includes both new records as well as changes.
Because of the unpredictable, large amount of updated records delivered by DocDB (which can cause delays in processing national office data), we are more selective in processing DocDB data by effectively spreading the weekly loads over a full week instead of processing the data when it is received. Doing so allows us to make sure that the US, EP, and PCT files (in particular) are processed in a timely manner.
In the following sections, we include information about data volumes and frequency of updates for the main raw data sources.
