Do copyright and copyright mean the same thing? Why does one meaning have two names?

In the theoretical circle of law, copyright and copyright are actually the same thing, and there is no difference, which is mentioned in the textbooks of intellectual property law.

Copyright is copyright, which refers to the rights (including property rights and personal rights) enjoyed by authors of literary, artistic and scientific works.

Whether it is called copyright or copyright, its terms and contents are basically the same. Judging from the legislative style of various countries in the world, the object of protection called copyright law in various countries includes not only written works, but also other works, including the content of neighboring rights. In a country named copyright law, the main content of protection is not the rights of publishers, but the rights of authors, and the objects of protection are basically the same as those in a country named copyright law.

Judging from the use in our country, the word copyright and the word copyright are also common, with the same meaning. Since copyright is copyright, the name of this law can be called copyright law or copyright law.
