Copyright is a form of legal protection provided to the creators of “original works of authorship” including literary, dramatic, musical, artistic, and certain other intellectual works, both published and unpublished. The Copyright Act (17 USC § 102) gives the creator or owner of copyright certain exclusive rights:
Many types of works are copyrightable -- including written, musical, graphic, and architectural works. However, a "work" cannot be just an idea to qualify for copyright protection. It must "fixed" to give it some permanency. The specific wording in the law is "fixed in any tangible medium of expression" -- so the "work" could be hand written or typed, photographed, recorded as audio or video, sculpted, or built. Copyright does not protect ideas, it only protects their expression or fixation. In most jurisdictions this means that as soon as you have expressed your idea in a tangible form, you hold the copyright. You hold the copyright whether or not you choose to formally register it with the US Copyright Office (more information on registering is available elsewhere in this guide).
The exclusive rights of the copyright owner are balanced for public interest purposes with limitations and exceptions. Copyright owners have the exclusive statutory right to exercise control over copying, distribution, and other exploitation of their works for a specific period of time. It should be noted that copyright owners may choose to license or permanently transfer or assign their exclusive rights to others. Once the copyright expires the work enters the public domain. Uses of a work which fall under the limitations and exceptions to copyright, such as fair use, do not require permission from the copyright owner. All other uses require permission.
