An invention, in order to be patentable, must be of a kind which can be applied for practical purposes, not be purely theoretical. If the invention is intended to be a product or part of a prod uct ,it should be possible to make that product. And if the invention is intended to be a process or part of a process, it should be possible to carry that process out or “use” it (the general term) in practice. “Applicability” and “industrial applicability” are expressions reflecting, respectively, the possibility of making and manufacturing in practice, and that of carrying out or using in practice. The word “industrial” in the same expression has a very special meaning in the terminology of patent laws. In common language，an “ industrial” activity means a technical activity on a certain scale, and the “industrial” applicability of an invention means the application (making, use) of an invention by technical means on a certain scale.
