1. What technical problems have been solved?
2. What is the difference from the existing technology?
3. How is the specific scheme realized?
It is necessary to apply for a patent as soon as possible before the relevant technology is made public.
Because in the process of patent examination, we need to consider the issue of technology disclosure. Once the related technology is made public before the patent application date, it means that it constitutes the existing technology of this patent application, and it is possible to lose the opportunity of authorization. This is especially obvious in the patent application of colleges and universities, because some colleges and universities or related researchers attach importance to papers, but do not realize the value of patents, and often only pay attention to new papers and ignore patent applications. There are also some students or teachers who are eager to need a thesis and often apply for a patent first, or some students publish their graduation thesis first because of graduation needs, and then realize that they need a patent and apply for a patent with relevant materials. A year or two later, when the invention patent is examined in substance, a patent that is expected to be granted will often be rejected by those published papers.
In addition to the above three points, patent technology or related patents need to be protected, and many people take patents as extra points for enterprise projects or personal evaluations. On the one hand, it needs to meet the relevance of its project or work field, on the other hand, it hopes to obtain relevant authorization certificates. However, there is uncertainty from patent application to patent authorization. In particular, there are a large number of domestic patent applications, and it is inevitable that there will be conflicts between patents and applications because of the late application time.
