Is the cost of patent pre-examination the same as that of priority examination?

Same. The cost of patent pre-examination is the same as that of priority examination, which is 3000 yuan. Patent pre-examination refers to the pre-examination service of patent application. Before the patent is formally submitted to China National Intellectual Property Administration, the protection center pre-examines the application documents, so that qualified patent applications can enter the fast examination channel. It is a part of the fast examination of patents implemented in China National Intellectual Property Administration.
