Is it easy for invention patents to enter the substantive examination stage?

Legal analysis: conduct a preliminary examination before the substantive examination stage of the invention patent. The main contents of the preliminary examination are as follows: 1. Review the format of patent application documents: check whether the patent application documents are complete and the format conforms to the regulations, such as whether the columns in the request are complete and correct, and whether the application fee has been paid according to the regulations. Those who pass the examination will be notified by the Patent Office (usually within one month) and get the patent application number. 2. Examination of the contents of the patent application: whether it "violates national laws, social morality or harms social public interests"; Whether it clearly falls within the scope of "no patent right is granted" as stipulated in Article 25 of the Patent Law, whether it belongs to national security or major interests, it should be kept confidential. Preliminary examination is relatively easy, as long as the patent application documents are complete, the format conforms to the regulations, and it does not violate national laws and social ethics, and does not harm public interests.
