The process of individual patent application is as follows:
1. It usually takes 20 days to one month to provide a disclosure letter and entrust an agency to write the application documents (if there is no entrusted agency, this step can be omitted).
2. Submit the application documents, get the notification of acceptance from the Patent Office, determine the application date, and submit an early public statement and request substantive examination on the day of submitting the documents, which can speed up the examination process.
3. The Patent Office will formally review the patent application documents for about 2-3 months, and enter the public preparation stage after the first trial is passed.
It takes about 6-8 months for the patent office to publish the invention application documents.
5. The time for the Patent Office to substantially examine the invention patent documents is about one and a half to two years, during which the examiner communicates with the applicant on the substantive content of the invention, namely novelty, creativity and practicality (entrusting the agency to communicate with the agency to determine the appropriate protection scope of the invention), and this communication may be repeated many times until it is revised to the satisfaction of the examiner.
6, the patent office issued a notice of authorization
7. The applicant shall go through the formalities for obtaining the patent certificate.
8. It takes about 2-3 months to get the patent certificate.
The whole process lasts about two and a half to three years, and the specific time depends on the speed of the examiner's review and the informative degree of the applicant's disclosure.
