Patents are generally a collection of practical methods, high-quality patent specifications and documents with economic value. However, we should not be superstitious about patents. Due to the need of technical competition, the quality of patents in some countries is quite poor, and many specifications are false. Especially in China, patents are generally regarded as a tool of deception, and packaging products have the means of "scientific and technological content" and the way to make a job with the government. So according to my current experience, 95% of the patents in China are fake or have no scientific and technological content. China's patent is as unreliable as the reaction yield reported in articles published in China journals. Because China does not stipulate that patents should have high-tech content, many patents in China are not original and new, and many are "synthetic" patents. Because the elasticity of the formula may be great, the patent of these low-grade ingredients is of little significance. However, the return is not big. After all, it is a little "shadow" and has certain hints. China's patents can be downloaded directly from China National Intellectual Property Administration. Unfortunately, the junk patent workers supported by backward China actually store the patent specification on a single page, and every time they download the specification of a 10 page, they need to click the mouse 100 times or more, and the complexity can be imagined. The reason for doing this is definitely not a technical problem, but the interests of some people? Because there used to be a website selling patent technical documents in China, which provided patent inquiry service under the guise of "national" service department. I also strongly appeal to some people in China's Intellectual Property Office who hinder scientific and technological progress not to be "self-styled", but to release all patents as soon as possible and make each patent specification into a file package. Like the United States, patent documents are downloaded as pdf files for free. Who else can use it to seek illegitimate interests?
American patent. The quality of American patents is as high as that of American scientific literature. For those who engage in synthesis, the patents applied by Americans can basically be repeated. However, many foreigners apply for American patents. If Japanese people apply for American patents, their credibility will be greatly reduced, because Japanese patents are not as low as those in China, and the disclosure of patents may be insufficient or the correct methods may be concealed and distorted. In recent years, the authenticity of American patents may also have a downward trend. But on the whole, I repeated many American patents before 1980, and they can be repeated accurately. U.S. patent inquiries can be registered directly on the U.S. national government website or in www.freepatentsonline.com, which is very useful.
