Applying for a supplementary protection certificate (SPC) and extension


By means of the supplementary protection certificate, the protection in Spain of a patent on a pharmaceutical or phytosanitary product that has a marketing authorisation in force in Spain can be extended up to  a maximum of 5 more years once the 20-year duration of said patent has expired. Under certain conditions, it is possible to extend the validity of a supplementary protection certificate already granted by means of a 6-month paediatric extension.
