Are patents issued by American and European intellectual property offices authorized? And there are unauthorized patents issued in China?

There are mainly two kinds of announcements issued by the patent office: one is that the patent application documents will be made public by the patent office after/0/8 months from the date of filing; The other is that if the patent office considers that it meets the conditions for granting a patent right after examination, it will grant a patent right and make the authorized patent documents public. In the United States, secret censorship was initially implemented. Patent documents will not be made public until the Patent Office decides to authorize them, but patent application documents will not be made public even after 18 months before authorization. However, since the United States joined the WTO, in order to comply with WTO rules, the United States has also stipulated a system of publishing patent application documents every 18 months. China and the European Union have been implementing the system of 65,438+08 months to open patent applications and authorize the disclosure of patent documents. Of course, the above provisions are only for invention patents. For utility model and design patent applications, because there is no substantive examination system, it must be a patent authorization document published directly after authorization.
