Supplementary Protection Certificate, SPC

Normally, you need a licence to use inventions relating to medicinal products or plant protection products. The licence requires comprehensive and time-consuming investigations to find out whether the products are safe for users and the environment. The investigations take up a significant part of the patent term, and that is why it is possible to extend the patent term by applying for a Supplementary Protection Certificate (SPC) for patents relating to medicinal or plant protection products.


An SPC is granted for a period of up to five years, but it may be extended, at request, for a further six months if it concerns a medicinal product for paediatric use and has undergone the appropriate testing.

The SPC enters into force when your basic patent expires at the end of the 20-year patent term. Example: if a basic patent filed on 10 October 2000 expires on 10 October 2020, the SPC will enter into force on 11 October 2020.
