In order to protect both patent applicants and public interest, we have the system of compulsory authorization in Taiwan’s Patent Act Article 76 (1), one of clauses to improve compulsory authorization. The similar clause is also rules in Agreement on Trade-Relted Aspects of Intellectual Property Rights (TRIPS) article 30 (b). When the patent agency decides whether to give applicant patent for patents or not, it is still one of the administrative procedures. When Patent Law or relative rules do not rule the procedure, we need to apply the Administrative Procedure Act (APA). But when we apply the APA, we could have a lot of explanations. Therefore, we should actually understand the clause of “making nonprofit- seeking use of a patent for enhancement of public welfare”, and especially regarding “Global Interest”, this conception need to include the “Global Interest” .And observing the implementation from the view of Due Process, whether “due procedure” or “legitimate organization”, we have something to s ay. In this article, we provide some suggestions for the procedure of compulsory authorization in Patent Act from interpretations of law and policies of legislation, we hope it could make the practice better and allow the rules of patent Act to become more mature in the future. Let the rules in Patent Act more mature in the future.
