The technologies involved are usually divided into patented technologies and non-patented technologies. Patented technologies are generally patented technologies, and non-professional technologies are their own secret recipes, or technologies that only a few people know and have not applied for patents. Of course, when choosing whether to apply for a patent, we should compare the scarcity of this technology. For example, in Coca-Cola, the formula of Coca-Cola has always been regarded as non-patented technology. Therefore, the specific formula of cola is still unknown to us. An event in which applying for a patented technology is likely to lead to the disclosure of one's secrets. So whether to apply for a patent is also very particular.
Patent shield can protect the technology developed by a company or an institution, and the research results of the company can be better protected through related protection. Others need to pay the relevant fees when they need to use the research results. For some world-leading and scarce patented technologies, the cost is higher.
That's why China advocates that enterprises need to keep researching and developing, and go to the forefront of the world faster through technological reform.
