Let's talk about how Chinese patent applications shorten the time of patent application: to shorten the application time, the method can be divided into two categories, the first type is general, applicable to all invention patents; The second type is the application for priority review or pre-review, which is suitable for some patents.

Let's start with the generic:

1. Advance announcement: When applying for an invention patent, it is required to publicize the patent application in advance and make a request for substantive examination at the same time, so that the patent application will generally be made public about 3 months after submission, and then enter the substantive examination procedure. While the normal patent application 18 months after the public and then enter the substantive examination procedure, this program can save about 12 months of time.

(2) Timely reply: In the substantive examination stage of the invention patent, it will generally issue at least one notice of review opinions, of which the reply period of the first review opinion is 4 months, and the reply period of each review opinion is 2 months. If the review comments are received in the shortest possible time to reply and submit, usually at least 3 months of time can be saved.

In addition, from the writing and reply strategy, reducing the game with the examiner can also shorten the patent application time.

Let's take a look at the acceleration of the application of some patents: priority examination and pre-examination are the more commonly used acceleration methods for Chinese applications. Through the way of priority examination, the approximate time from application to authorization of an invention patent is about 18 months; Through the pre-examination, an invention patent from application to authorization takes about 5-8 months. However, these two methods have their own application, not all applications have the opportunity, this depends on different regional policies, restrictions in different regions and patent areas and other factors, need to be specific judgment.

Speaking of China, let's talk about overseas patent applications.

The general approach of overseas patent application acceleration is similar to that of Chinese application, mainly to shorten the time of reply, to minimize the game with the examiner through writing and reply strategy, and to land early. In addition, the international PPH approach is a more common way to accelerate overseas patents. However, unlike Chinese patent applications, in many overseas countries or regions, advance publication has no impact on the speed of examination.

In addition, overseas countries or regions also have their own acceleration methods, such as Track1 acceleration in the United States, PACE acceleration in Europe, etc., which need to be selected according to specific national policies and the actual situation of the case.
