Legal analysis: An application for a patent for invention includes two stages: first, preliminary examination (about 6 months), and second, actual examination (10-20 months). After submitting it to the patent office, there will be an acceptance notice with the patent number on it. After submission, it will enter the preliminary examination stage. After preliminary examination about 6 months from the date of submission, the patent will be made public and then enter the actual examination. The practicality, novelty and creativity of the joint trial patent actually tried will be uncertain several times if there are problems in the middle, so the final authorization time is uncertain if it can be authorized. If all goes well, you can authorize it in a year or so at the earliest, that is, you have a certificate.
