A copyright is a legal tool that gives the creator of a creative work (literal, artistic, musical, etc.) the sole right to publish and sell that work. Copyright protection extends to a wide array of work which includes, but is not limited to, books, stories, poems, song lyrics, computer programs, music compositions, architectural works, motion pictures and audiovisual works. Copyright owners control the reproduction of their work, receive payment for reproduction, and can sell reproduction rights to others. Violation of a copyright by another person or entity is infringement and is the subject of complex intellectual property litigation.
