There are two different levels of participation possible:
- Accessing Office - Examiners at the accessing office have access to the WIPO CASE web portal and can use the system to search for patent applications at other participating offices and to retrieve the documents that are made available by those offices;
- Depositing Office - The depositing office makes available the search and examination documentation for patent applications filed at that office. Technically, this may be done by uploading the documents into the WIPO CASE system hosted by WIPO, or by making the documents available to the WIPO CASE system via secure web services.
