Let me tell you briefly, but it is still recommended that you entrust a local patent agency. The number of agencies in Guangdong is second only to Beijing, and there are still many:
Applying last month If an invention patent is written by an inexperienced person, it is almost 100% certain that you will definitely receive a notice of correction or an office action. As long as you do not reply, the application will be withdrawn; if you reply, but the reply If it is inappropriate, it will most likely be rejected. As a patent agent, my above meaning is clear. I still recommend that you entrust a patent agency immediately to see if there is any room for remediation in your application. If not, apply again immediately. If the application was withdrawn last month, if There is room for remediation, and the application documents can be modified three months from the date of application. Of course, such modifications are subject to many restrictions.
The statistical approval cycle for invention patents is about two and a half years, the fastest is 18 months, and the longest I have seen is more than fourteen years. Of course, 90% of applications will have results in about two and a half years. Individual applications may receive results in about 10 months, and most of them are rejected. ——Patent attorney
