Can a patent be reexamined if it is rejected in the first instance?

If the applicant or inventor thinks that it can still be saved, or thinks that the examination is wrong, he may apply for a patent rejection review. After the patent is rejected, there is a hint in the rejection decision that the patent can be re-examined. This is a relief opportunity to avoid wrong trial after the patent application is rejected. If you think your product or idea is very good, the result is that the Patent Office issued a review opinion, which was rejected after reply, but its technology does meet the requirements of three characteristics, and it is recommended to review it; Although there are many cases of obtaining patent authorization through patent re-examination, because patent re-examination will involve money and time, it is unnecessary to insist on it if, after analysis and comparison, it is considered that the reasons for rejection are sufficient, there are indeed big loopholes in technology and the re-examination authorization is not high.
