Good Luck
We want the Patent Opposition Database to help you to learn, share and challenge patents.
We hope that you will be successful in your work to make medicines available to all.
Civil society and public interest groups across the world have contributed information to this site. Their hard-won knowledge and experience shows that it is possible to successfully challenge patents.
Challenging patents can save lives. And that’s why we hope you’ll agree that although the process is long and complex, it is worth following.
