The Agreement does not define this notion. However, national legislation in developed WTO members has traditionally excluded, inter alia, discoveries and scientific theories.115 The reason for the exclusion of discoveries stems from the basic rationale of patent protection: to reward human ingenuity and creativity as a contribution to the advancement of humankind. The inventor, in exchange for his/her efforts and readiness to make his/her invention available to the benefit of society is granted a reward, i.e. a monopoly to exploit the invention over a limited period of time.
