Simply put, the authorization of legal status means that the patent right has been obtained. Openness is substantive examination, which is stricter than the first instance, and 50% of inventions are rejected here!
Reason:
1, the power of the patent office is limited, and it may not be possible to find out whether this patent is plagiarized, so it is open for everyone to see the supervision.
2. Patents are generally technical, which can better promote the research in this field after publication. Others can study other things on this patent (if you apply for a post-technology patent, you should give the former patentee certain benefits).
3. If there are other similar technologies that have not been patented, you will know that it is too late after publication, and the law is equivalent to telling you not to implement them. If you don't announce it, then the other party can say, "I didn't check it in the patent office. How do I know?" But after a certain period of time, it is presumed that you know.
4. After the announcement, you still can't use the patent within the protection period of several years, unless there are special provisions in the law (for example, scientific research and teaching are used in a small range, but not for profit).
