One of the conditions for obtaining an SPC is that “the product is protected by a basic patent in force”. The Court of Justice of the European Union (CJEU) clarified to what extent a product must be identified by the claims to meet this condition in Teva, Eli Lilly, and Royalty Pharma.

In Eli Lilly, the CJEU notes that an active ingredient which is not identified in the claims of a basic patent by means of a structural or functional definition cannot be considered to be “protected by a basic patent.”

The active ingredient does not, however, have to be identified in the claims by a structural formula. A functional definition of the active ingredient may suffice if it is possible to reach the conclusion on the basis of the claims (interpreted in light of the description of the invention) that they relate “implicitly but necessarily and specifically, to the active ingredient in question.
