Supplementary Protection Certificates are of great importance to the pharmaceutical industry as a method of increasing the length of market exclusivity for successful medicines to compensate for delays in marketing a product which results from compliance with the regulatory requirements. Providing a comprehensive commentary to the Supplementary Protection Certifcate Regulations (the SPC Regulations), this practical handbook highlights the various issues and uncertainties in the SPC Regulations which have not only been illustrated by EU wide case law but by cases which currently remain undetermined. The invaluable analysis provided by this work enables practitioners to make informed and strategic decisions in relation to these important rights, whether they are involved in the application and grant of these rights or their enforcement. The work provides the relevant background to the SPC Regulations in order to define their underlying purpose and to analyse problematic elements of this, before going on to provide an EU wide commentary on the individual provisions of the SPC Regulations.
