For an application for a patent for invention, due to the long examination time, it must be made public before the substantive examination. The advantages of doing this are: (1) It is conducive to the rapid spread of the latest technology, so that relevant departments and units can understand the latest technological development trends as soon as possible and formulate development strategies; (2) Repeated research can be avoided, and waste in the research and development process can be reduced; (3) Being able to promote the faster research and development of new technologies under the inspiration of others' inventions; (4) Anyone can put forward opinions to the Patent Office on a patent application that does not conform to the provisions of the Patent Law, and explain the reasons, so as to reduce possible mistakes in the examination.
For the applicant, because after the publication of the application for a patent for invention, the public can know the content of the application and it is possible to implement the invention, in order to safeguard the interests of the applicant, certain protection must be given, which is the temporary protection of the invention patent. Because the application for a patent for invention has not been substantially examined at this time, a considerable part will be rejected in the end. Considering the public interest, the applicant has no right to ask for suspension of execution, but can ask for compensation. Therefore, Article 13 of the Patent Law stipulates that after the publication of an application for a patent for invention, the applicant may require the entity or individual exploiting the invention to pay an appropriate fee.
