Anthony Ball explores what SPCs are, the strict requirements for obtaining them, and why they matter for businesses operating in these sectors.
Thank you
It is not possible to extend the term of a patent in the UK and Europe – but it is possible to extend the term of protection for pharmaceutical products and plant protection products for up to five and a half years. That is achieved using “Supplementary Protection Certificates” (“SPCs”). An SPC provides patent-like protection, but only for a specific product, rather than everything which falls within the scope of the patent covering the product.
The following are required to get an SPC for a pharmaceutical or a plant protection product:
The application for an SPC must be filed within six months of the date of grant of the patent or within six months of the date of grant of the Marketing Authorisation, whichever is later.
Only one SPC per product is allowed, and so a final requirement for the grant of an SPC is that the product has not already been the subject of an SPC.
The duration of the SPC is determined using the following calculation:
(Date of first Marketing Authorisation in the EU or UK – Filing date of patent) – 5 years
The exception to this is that if a pharmaceutical product was tested in compliance with an approved paediatric investigation plan, a six month extension of the SPC may be granted, resulting in the maximum SPC duration being five and a half years.
SPCs are a complex and specialist area of significant commercial importance. If you have any questions on this topic, please contact Anthony Ball or your usual Keltie advisor to discuss further.
