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
- Data from national registers for AU and EP
- Extensions and associated drug names for AU and US
New raw data is loaded as soon as published and includes both new records as well as changes.
The loading of PDFs and other attachments generally occurs after the XML as they are delivered to us separately. In order to make the XML available as quickly as possible, we do not constrain delivery of the text until the images arrive. Attachments and images are usually available within 24 hours of the XML.
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 files covering newly published documents are processed in a timely manner.
The data we receive from patent offices may differ from what is available through their portals as they are separate products with different maintenance procedures and schedules. As a result, it may be helpful to consult the /legalstatus service if a more current source is needed.
In the following sections, we include information about data volumes and frequency of updates for the main raw data sources.
