Protecting your Intellectual Property in te music business.
Trademarks, copyrights, and patents protect different types of intellectual property. A trademark typically protects brand names and logos used on goods and services. A copyright protects an original artistic or literary work. A patent protects an invention.
For copyright purposes, a song (music and lyrics) and the sound recording of it (the recorded performance/production) are separate works. To register both with one application, the copyright ownership of both must be the same. Generally this means that the same people wrote the song and created the recording.
