Copyright provides protection to works of authorship, including literary, dramatic, musical, and artistic works, as well as software code and digital content. Under copyright, the creator has the exclusive right to reproduce, distribute, perform, display, and adapt their work. Copyright automatically applies upon the creation of a work, but registration with a governmental body can enhance protections and facilitate legal enforcement. The duration of copyright protection varies by jurisdiction but generally lasts for the life of the creator plus an additional number of years (often 70 years). Copyright does not cover ideas, methods, or systems but protects the expression of those ideas as they are fixed in a tangible medium.
