What is the principle of defining the scope of patent protection in Shenzhen? China's Patent Law has absorbed the beneficial experience of foreign countries and defined the scope of patent protection for inventions, utility models and designs in different ways. So what is the principle of defining the scope of patent protection in Shenzhen? What is the principle of defining the scope of patent protection in Shenzhen? 1. Principle of central restricted system. As long as the whole idea of invention and creation is fully revealed through the contents of the specification and its drawings, the scope of protection will be extended to a certain range around. As long as the patentability conditions for granting patent rights are met, there is no need for high abstraction and generalization. Therefore, the central restriction principle can be further expanded and supplemented compared with the above-mentioned peripheral restriction principle, which can effectively prevent someone from using the loopholes in patent writing to escape the corresponding legal investigation in patent disputes, which is beneficial to enterprises. However, due to its vague scope of protection, there may be some unfair phenomena to the public, which is difficult to distinguish from it. Second, the principle of peripheral restrictions The principle of peripheral restrictions can only be understood and interpreted strictly in accordance with the literal meaning of the claims, and no other extended interpretation is allowed. Although this method can clearly present the scope of patent protection, it also has great risks. Because word games are very easy to find, once loopholes appear, they will be in a weak position in patent disputes. Therefore, the requirements for patent applicants or patent agents are extremely high, and patent writing should be considered every word. Third, the principle of compromise is between the above two. This principle is not limited to the external restrictions, but also cleverly avoids the central restrictions and expands the scope of patent protection to infinite injustice and embarrassment. It is a better way to find a balance of interests between the patentee and the public. At present, many countries use the eclectic principle to write patents, while China basically adopts the eclectic principle when defining the scope of patent protection.
