There are several fields you can use to search for an applicant or assignee. See Associated Parties for a full list of searchable parties. Many of these fields are available in various formats, including the original format as filed by the applicant and the EPO’s standardized format. More information about formats can be found on the Common XML Attributes page.
A particularly helpful field to be aware of is the pa field, which provides a comprehensive search of the applicant, assignee, and reassignee fields. We also offer search fields like asgfull that allow you to search the name and address fields together, which may help to distinguish entities with the same name in different locations.
