1. Due to the lack of means to solve technical problems, the present invention cannot be realized. For example, the instructions only give tasks and ideas, or only indicate a desire or result, and do not give any technical means that technicians in the technical field can implement. For another example, the solution is given in the manual, but for the technicians in this technical field, the solution is vague and cannot be implemented according to the contents recorded in the manual.
In this case, because ordinary technicians in this field can't realize the invention according to the contents recorded in the manual, and then understand the technical problems and produce the expected results, the result is usually that the application is rejected.
2. Lack of technical content needed to understand or reproduce the invention, and it is often a key part of the content. It is understood that most of the reasons for this situation are that the applicant deliberately concealed the core content of his invention for technical confidentiality. In fact, granting the applicant a patent and protecting his patent does not help the applicant to protect his patent, and it will never be known or used by others, thus forming a monopoly. Therefore, the Patent Office will announce the patent applications, so that the public can see these patent applications in time, and use these patent publications selectively according to their own needs, and copy inventions or utility models according to the contents recorded in the application documents, so as to achieve the purpose of promoting inventions and creations.
Of course, there should be conditions for others to exploit the invention or utility model, such as paying the patentee a certain remuneration. However, if the applicant does not fully disclose his invention for the sake of confidentiality, it will violate the original intention of establishing the patent system. Moreover, this practice of the applicant is also unfavorable to himself. Because the examiner's attitude towards such cases tends to reject the application because of its insufficient publicity. If the applicant tries to add unpublished contents to the application documents in order to obtain the patent right, it may cause modifications beyond the scope of the original application and may also lead to rejection. In this way, an invention with potential value will not be patented.
