WIPO CASE - Centralized Access to Search and Examination

Secure exchange of search and examination documents to facilitate work sharing between patent offices

The WIPO CASE system enables patent offices to securely share search and examination documentation related to patent applications in order to facilitate work sharing programs.

Many patent applications are filed in multiple offices and patent examiners can increase the efficiency and quality of their work by sharing their examination results.

This system was initially developed by the International Bureau in response to a request from the Vancouver Group offices (the patent offices of Australia, Canada and the UK). Based on their requirements, an initial system was deployed in 2011. The system was further enhanced during 2012 and is now operational for exchange of documents between examiners in the three offices.

Since March 2013, any patent office may join the system by notifying the International Bureau that it is willing to participate according to the framework provisions PDF, framework provisions of the system. The office will choose whether it wishes to be a depositing office or only an accessing office and technical choices need to be made for the exchange of documents between the office and the system.

Description of the system

WIPO Centralised Access to Search and Examination (WIPO CASE system) provides a platform to share information with regards to search and examination reports among participating local intellectual property (IP) offices.

The objective of this application is to improve the efficiency of the Search and Examination process done at local IP offices. Time taken for examination work can be reduced by sharing information. The local IP office can carry out further examination work if deemed necessary after analyzing existing information of any equivalent filing at another participating local IP office.

Consultative group

The WIPO CASE consultative group is made up of representatives of all depositing offices. The consultative group is responsible for:

  • reviewing and approving technical specifications;
  • conducting a technical review of proposed participating offices;
  • deciding on the participating of new offices;
  • approving changes to the Framework Provisions.

Restricted access to the group

Participating Offices

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.

Dossier Linkage System

The IP5 (Japan Patent Office, European Patent Office, Korean Intellectual Property Office, State Intellectual Property Office of the People’s Republic of China and the United States Patent and Trademark Office) has developed in the One Portal Dossier (OPD) which is a platform for the secure exchange of patent search and examination documentation (dossier information).

The JPO’s OPD system has been linked to the WIPO CASE system with a view to enable exchange dossier information between two systems. Interested IP5 offices will be able to use the linkage system to retrieve documentation from WIPO CASE offices and interested WIPO CASE offices will have access to the documentation from IP5 offices if they agree to use the linkage system according to the Guideline on Use of the Dossier Access System linked with One Portal Dossier and WIPO-CASE as a Pilot Case. The offices participating in the linkage system are listed here. PDF, Dossier linkage system
