As the readers well know, the European Patent Convention (“EPC”) system allows the validity of European patents to be challenged through two different routes: (i) oppositions filed before the European Patent Office (“EPO”); and (ii) revocation actions filed before national Courts.

In the oral proceedings held in the EPO appeal case T 1760/11 the Board of Appeal (BoA) 3.3.01 selected one single closest prior art (CPA) document for the inventive step assessment and then denied the opponents the opportunity to present inventive step attacks starting from other CPAs.
