Copyright starts when the work is fixed.
U.S. copyright generally starts when an original work is fixed in a file, recording, photo, or page.
Copyright protects original expression. It does not protect ideas, titles, or facts. Human authorship is required. U.S. copyright generally exists automatically when a work is fixed; notice is not required for the right to exist.
The owner can typically control copying, distribution, public performance or display, and derivative works.
The author is usually the first owner unless a contract or work-made-for-hire rules say otherwise. An exclusive transfer requires a writing.
For works from 1978 on, the term is generally the author’s life plus 70 years. For a joint work, the term is generally the last surviving author’s life plus 70 years. Work made for hire often lasts 95 years from publication or 120 years from creation, whichever is shorter.
