专利包含两层意思:保护与传播。专利法规定,发明专利保护20年,实用新型专利和外观设计专利保护10年,此后法律不再给予保护,可以在社会上自由传播。专利不仅让发明人得到了法律的保护,在有限的时间内获取比较高的利润,更重要的是发明人对社会做出了贡献:通过专利让技术更快地为人所知,打个比方:祖传秘方如果有副作用,永远不会有人给它改进。总之,专利是开放社会的产物。如果是非商品化社会,专利制度是没有意义的。
Patent contains two layers of meaning: protection and dissemination. According to the Patent Law, the invention patent is protected for 20 years and the utility model patents and design patents are protected for 10 years. Since then, the law is no longer protected and can be freely distributed in the society. Not only does the patent protect the inventor against the law, but it is even more important for the inventor to make a contribution to the society in a relatively short period of time: to make the technology known to the public by the patent more quickly, for example: If there are side effects of ancestral secret recipe, it will never be improved. In short, patents are the product of an open society. If it is non-commercial society, the patent system is meaningless.
