Patent Opposition Database
The Patent Opposition Database is a project by ITPC, Third World Network, and MSF Access Campaign.
The Patent Opposition Database allows you to:
- Learn more about the patent oppositions process.
- Gather the necessary knowledge and resources to build your own opposition.
- Make contacts with other people who have similar interests in opposing specific types of patents.
- Track specific drugs or conditions by subscribing to email alerts.
You can search for information by drug or disease name, document type (such as court cases, patent applications, patent office decisions, and others), country, and patent applicant. This will help you do the research on medicines and discover successful tactics used in prior cases.
