Screening Criteria at the Japan Patent Office
Patent applications will be examined by the Examiner one by one at the JPO as to whether to accept registration of the application. Screening criteria are specified by law as follows:
Novelty and inventive step
Novelty refers to public knowledge of a relevant invention, suggesting that any arts related to public matters or products available on the market prior to its application are unpatentable due to lack of novelty. Any matters easily conceived of from arts publicly known at the time of application are also unpatentable due to absence of inventive step even if they possess novelty.
Priority of application
A patent application for an invention identical with or similar to another should be filed prior to the other, which is a requisite for patentability.
Not contrary to public order or morality
Even an invention having novelty and inventive step is unpatentable as far as it is contrary to public order or molality or public interest.
