How long does it usually take from patent application to first instance? At what stage is the application for "early disclosure"? When can it be made public at the earliest?

1. If the admission notice is delivered in person, you can collect it on the spot; If it is mailed, it will be received within 15 days to 1 month (you can get the acceptance receipt the next day after submission, and you can get the official acceptance notice stamped with the red seal one month later).

2. The first-instance qualified notice will be received in about 3-9 months.

3. China's patent law stipulates the "rule of early disclosure": if the patent office considers that the application for a patent for invention conforms to the provisions of the patent law after preliminary examination, it will be published after 18 months from the date of filing. The so-called early disclosure means that the applicant can request the early disclosure of his patent application from the date of application and the priority date, and shall submit an early disclosure statement. After the early public statement has passed the preliminary examination of the Patent Office, it can immediately enter the public procedure. The pre-public statement is only applicable to the application for a patent for invention. That is to say, if a patent application is submitted in advance at the same time, the patent will generally be published on the patent office website in about 4-6 months; If it is not required to be made public in advance, the patent will be made public after 18 months from the date of application and granted for 2-3 years. General utility model and design patents can be published and authorized after half a year of preliminary examination.
