All rights reserved means that the person who created something, like a book or a song, has the right to decide who can use it and how. It's like saying "this is mine, and you can't use it without my permission." This phrase used to be required for copyright protection, but now it's not always necessary.
Definition: All rights reserved is a phrase that is used to indicate that the copyright owner has exclusive rights to reproduce, distribute, and display their work. This phrase is required as part of a valid copyright notice under the Buenos Aires Convention.
For example, if a photographer takes a picture and wants to protect their rights to that picture, they would include the phrase "All rights reserved" in the copyright notice.
It's important to note that not all international copyright treaties require this phrase. However, since the Buenos Aires Convention does require it, it's still commonly used today.
