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. The data is provided directly by the biopharmaceutical companies and hosted by WIPO.

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. While it is not a tool to provide Freedom to Operate analysis, it facilitates access to patent information and can improve efficiency in procurement processes.

Pat-INFORMED is an initiative of WIPO, the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA) and 20 leading, research-based biopharmaceutical companies.

These 20 companies chose to voluntarily provide information on key patents for their approved pharmaceutical products in therapeutic categories covered by Pat-INFORMED. They also commit to respond to bona fide inquiries from procurement agencies.

WIPO builds on its large database expertise to hosts this data, providing links to Patentscope when possible. Patent data is provided and updated directly by the companies.
