The Rights Copyright Gives
A copyright owner gets to do, or authorize others to do, the following things: U.S. Copyright Code, 17 U.S.C. § 106
- Make copies of the work
- Distribute copies of the work (by selling, renting, lending, or giving it away)
- Perform or display the work publicly
- Make derivative works, like translations, adaptations, and reinterpretations
A copyright owner can dole out some or all of those rights to other people or entities, by transferring ownership or granting licenses. Ownership or license rights can be shared by any number of people or entities.
What Copyright Protects
The copyright rights outlined above only apply to works that fit into one of these eight categories: U.S. Copyright Code, 17 U.S.C. § 102(a)
- literary works
- musical works, including accompanying words
- dramatic works, including accompanying music
- pantomimes and choreographic works
- pictorial, graphic, and sculptural works
- motion pictures and other audiovisual works
- sound recordings
- architectural works
Some of the categories are bigger than you might think. For instance, "literary works" includes almost all text-based media, including computer code.
Works that fit into one of the categories above must also be "fixed in a tangible medium of expression" - that is, saved in some form - in order to qualify for copyright protection. Almost anything counts as "fixed" - a drawing on a chalkboard or whiteboard, or a file saved in a computer's memory would qualify. However, unfixed works such as improvisational speeches or music aren't protected by copyright.
A work also must include original creative expression to qualify for protection. The amount of originality required is pretty low, but just "sweat of the brow" is not enough. For example, writing out an alphabetical list of all Nobel Prize winners may take a lot of work, but it doesn't really contain any original expression. By contrast, if you add annotations and commentary to that list, you could own a copyright in the annotations and commentary.
What Copyright Doesn't Protect
Copyright does not apply to: U.S. Copyright Code, 17 U.S.C. § 102(b)
- procedures, processes, systems, methods of operation
These qualify for protection and ownership under patent law, and patent and copyright do not usually overlap.
- ideas, concepts, principles, or discoveries
Broadly speaking, these are not ownable under any form of U.S. intellectual property law. This reflects important values about intellectual freedom and encouraging innovation.
- titles, names, short phrases and slogans; familiar symbols or designs, mere variations of typographic ornamentation, lettering, mere listings of ingredients or contents
These are considered to fail the requirement of originality.
- other unoriginal or unfixed works

How To Get a Copyright
Creators today don't have to do anything to get a copyright; a work that qualifies is automatically fully protected by copyright from the moment it is first "fixed". Publication is not a requirement for copyright protection, and even formal registration is purely optional. There is also no requirement to include a copyright notice, date, the "circled c" © symbol, or any other information on the work in order to own a copyright.
Employers usually own the works created by employees in the course of their employment, and commissioned works ("works for hire") are usually owned by the party that commissioned them. Someone who is not a creator may acquire ownership of a copyright through a written agreement with the creator.
Copyrights can be registered with the U.S. Copyright Office by any legal owner, at any time during the term of copyright protection. Early registration (within 3 months of publication, and/or before infringements are discovered) brings some benefits if a lawsuit ever arises. There is a nominal fee for registration, and a copy of the work must be deposited with the Copyright Office. (More info: Copyright Office F.A.Q.)
How Long Copyrights Last
For works created today, copyright protection starts automatically as soon as a work is created, and lasts for 70 years after the death of the creator.
Because copyright terms have been changed several times, the term lengths for older works vary widely, based on a bewildering number of factors. Learn more about how copyright terms end, and works rise into the public domain.
