Doesn't the world intellectual property need an objective form perceived by people? Why?

The object of intellectual property must be perceived by people. The "knowledge" of intellectual property refers to the results of people's creative intellectual activities, and there is no need for an objective form of people's perception.

"Intellectual property" is a foreign word, and its concept and meaning are directly stipulated by law. In China, intellectual property is the name of scientific and technological achievements such as copyright, discovery and invention, and also the name of patent right and trademark right.
