One is the first trial (about 6 months)
First, the actual trial (about 10-20 months)
Preliminary examination stage
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 six months from the date of submission, the patent will be made public and then enter the actual examination.
Actual trial stage
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.
