The terms patent, copyright, and trademark are all used in the context of intellectual property. Although intellectual property or intellectual ideas are created in the human mind, intellectual property does not refer to the ideas. It is how the idea materialises itself and the end result that is protected with a patent, a copyright, or a trademark. The design of a fuel-efficient car maybe patented but not the idea. The story or the manuscript of a book is copyrighted and not the idea of the book itself. When you start a new company, the logo is trademarked and not the idea of creating a logo.
