Copyright is a type of intellectual property that protects original works of authorship as soon as an author fixes the work in a tangible form of expression. In copyright law, there are a lot of different types of works, including paintings, photographs, illustrations, musical compositions, sound recordings, computer programs, books, poems, blog posts, movies, architectural works, plays, and so much more!
Works are original when they are independently created by a human author and have a minimal degree of creativity. Independent creation simply means that you create it yourself, without copying.
Therefore the following are NOT under copyright: titles, names, short phrases, and slogans; familiar symbols or designs; mere variations of typographic ornamentation, lettering, or coloring; and mere listings of ingredients or contents.
Also, since copyright protects expression, and NOT ideas, procedures, methods, systems, processes, concepts, principles, or discoveries.
A work is fixed when it is captured (either by or under the authority of an author) in a sufficiently permanent medium such that the work can be perceived, reproduced, or communicated for more than a short time. For example, a work is fixed when you write it down or record it. (Content is courtesy of this website)
