Details

Supplementary protection certificates (SPCs) provide additional protection for patented medicines and pesticides, which are required to go through extensive testing and approval before they can be authorised for sale.

New legislation on SPCs came into force on 1 January 2025. This guidance sets out what SPC holders and applicants need to do as a result of that legislation. This will depend on what marketing authorisations your SPC or SPC application relies upon, and its status on that date.

Guidance is also provided on issues that customers need to be aware of when viewing details of SPCs via our online services, following this legislation.

This guidance deals with SPCs for medicines for human use only. SPCs for veterinary medicines and pesticides are not addressed.

(There is a separate small change for veterinary medicines on 1 January 2025. This will reflect that marketing authorisations for Northern Ireland are being granted under different law. It will not require SPC applicants or holders to take any additional action.)
