物权是有形的,知识财产有的无形,有的无体,有的既无形也无体(比如,人的创意)。我国已故的著名的知识产权学者郑成思先生曾经打过一个比方:对于诸如一张桌子,所有人可以通过占有它而基本上达到保护自己的财产的不受侵害的目的,而对于诸如一项发明、一部作品或一个商标,所有人基本上不能通过占有它们而达到保护它们不受侵害的目的。因为没法将知识财产控制在所有人的手里,个人的知识财产,很多时候成了一种“公共产品” Property rights are tangible, some invisible intellectual property, some bodyless, some invisible and invisible (for example, people’s ideas). Mr. Zheng Chengsi, a late-famous intellectual property scholar in our country, once played an analogy: for such things as a table, all people can basically achieve the unprotected purpose of protecting their own property by possessing it, , A work or a trademark, the owner basically can not achieve their goal of protecting them against infringement by possessing them. Because it is impossible to control the intellectual property in the hands of all, personal intellectual property has often become a “public good”
