In addition, it is common sense that the disclosure of a group of compounds comprises all of the group’s elements, even if not specifically mentioned. Countries may confirm the novelty of those specific elements that were not expressly mentioned in the prior art group of compounds. Instead of the novelty standard, it would be the inventive step requirement that would act as the principal floodgate against selection patents. The essential issue to examine would be the question of whether the improved properties of the species (as compared to the prior art genus) are beyond what a skilled chemist may expect.
