What are the procedures for national invention patent application? The invention patent application process in China is different from that in other countries. Here is a brief summary of the invention patent application process in mainland China. I hope it can be of useful reference value to inventors and applicants! What are the procedures for applying for a national invention patent? National invention patent application procedures (1) Patent granting principles: According to the basic principles of the patent law, only one patent right can be granted for the same invention. When two or more people file patent applications for the same invention, there are two principles: one is the first-to-invent principle, and the other is the first-to-file principle. The first-to-invent principle means that if two or more people file patent applications for the same invention, the patent right should be awarded to the person who made the invention first, regardless of the time when they filed the patent application. However, because when adopting this principle, many practical difficulties are often encountered in determining who is the first inventor, therefore, currently only a few countries in the world, such as the United States, Canada and the Philippines, adopt this principle for patent applications. The so-called first-to-file principle means that when two or more people file separate applications for the same invention, the patent right will be granted to the latest person regardless of the order in which they made the invention. Whoever applies first, China and most countries in the world adopt this principle. National invention patent application procedures (2) Patent review procedures: Countries have different requirements for the review of patent applications, and basically implement two different systems. Some countries implement a formal examination system, which only examines whether the form of the patent application meets the requirements of the law, but does not examine whether the invention meets substantive conditions such as novelty. Some countries implement a substantive examination system, which not only examines the form of the application, but also conducts a substantive examination on whether the invention meets conditions such as novelty, advancement, and practicality. Only inventions that meet the above patent conditions will be granted patent rights. China and most countries in the world adopt a substantive review system. There is no limit to the number of inventors of a patent. It can be one person or a plurality of people. As long as the inventor meets the legal requirements, he or she can become the inventor of the patent. Of course, patents still need to be applied for in order to enjoy them.
