1971: Film director loses copyright 05

T:
For example, here is a book. This is a work of the Agency for Cultural Affairs.
If I wrote it, I would publish the book with "Author: Takezawa" written on it. That book would be my work.
I go home. If I own a building, this means I own a piece of real estate.
How can I show this (to the outside world)? I would go to the registry office and register the house, and it would become "this piece of real estate belongs to Takezawa."
This book (personal property) and real estate are called "tangible property" and can be seen.
You might ask if this book is just paper, but it's not. Someone wrote down what they were thinking, word for word, on manuscript paper, and compiled it into a book.
It is printed, but it is based on the original manuscript.
The manuscript contains the thoughts and feelings of the person who wrote it.
How do you protect invisible thoughts and feelings when they are expressed in a physical form?
Intangible property rights are nowadays referred to as intellectual property rights. How do you protect them?
The products of ideas or emotions can be expressed in the form of music, literature, or essays. Each of these is a work of authorship.

I think it's fair to say that copyright law protects intangible property, intellectual property rights, that are expressed in a visible form to the outside world.
