For the complete list of mandatory procedural requirements, see Article 31, TRIPS Agreement. For instance, patents may only be granted to inventions that are “new, involve an inventive step and are capable of industrial application” (Article 27.1, TRIPS Agreement). In implementing this provision, every member will have to reflect these minimum requirements in its domestic law and practice. However, the TRIPS Agreement does not contain any definition of novelty, inventive step or industrial applicability.60 Members are free to define in their domestic laws when and how an invention meets these criteria.
