Pat-INFORMED – The Gateway to Medicine Patent Information

The Patent Information Initiative for Medicines (Pat-INFORMED) provides a service to the global health community, particularly those involved in procurement of medicines, by facilitating easy access to medicine patent information.

Anyone can search the Pat-INFORMED database simply by entering a medicine’s INN (International Nonproprietary Name) to obtain relevant information about its patent status in a particular country. Uniquely, Pat-INFORMED also provides a facility for procurement agencies to make follow-up inquiries directly with participating companies.
