Patents, Trademarks, and Copyrights are three types of intellectual property protection. They are different and serve different purposes. Patents protect inventions, and improvements to existing inventions. Trademarks include any word, name, symbol, or device, or any combination, used, or intended to be used in commerce to identify and distinguish the goods of one manufacturer or seller from goods manufactured or sold by others, and to indicate the source of the goods. Service marks include any word, name, symbol, device, or any combination, used, or intended to be used, in commerce, to identify and distinguish the services of one provider from services provided by others, and to indicate the source of the services. Copyrights protect literary, artistic, and musical works. For general information, publications and other copyright related topics, you may visit their Web site at http://www.copyright.gov. Copyrights information can be obtained from the U.S. Copyright Office, Library of Congress, Washington, DC 20559 or you may call 202 707-3000 or 202 707-6737 (TTY).

What is copyright?
Copyright is a form of protection grounded in the U.S. Constitution and granted by law for original works of authorship fixed in a tangible medium of expression. Copyright covers both published and unpublished works.

What does copyright protect?
Copyright, a form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture. Copyright does not protect facts, ideas, systems, or methods of operation, although it may protect the way these things are expressed. See Circular 1, Copyright Basics, section "What Works Are Protected."

How is a copyright different from a patent or a trademark?
Copyright protects original works of authorship, while a patent protects inventions or discoveries. Ideas and discoveries are not protected by the copyright law, although the way in which they are expressed may be. A trademark protects words, phrases, symbols, or designs identifying the source of the goods or services of one party and distinguishing them from those of others.

When is my work protected?
Your work is under copyright protection the moment it is created and fixed in a tangible form that it is perceptible either directly or with the aid of a machine or device.

Do I have to register with your office to be protected?
No. In general, registration is voluntary. Copyright exists from the moment the work is created. You will have to register, however, if you wish to bring a lawsuit for infringement of a U.S. work. See Circular 1, Copyright Basics, section “Copyright Registration.”

Why should I register my work if copyright protection is automatic?
Registration is recommended for a number of reasons. Many choose to register their works because they wish to have the facts of their copyright on the public record and have a certificate of registration. Registered works may be eligible for statutory damages and attorney's fees in successful litigation. Finally, if registration occurs within 5 years of publication, it is considered prima facie evidence in a court of law. See Circular 1, Copyright Basics, section “Copyright Registration” and Circular 38b, Highlights of Copyright Amendments Contained in the Uruguay Round Agreements Act (URAA), on non-U.S. works.

I’ve heard about a “poor man’s copyright.” What is it?
The practice of sending a copy of your own work to yourself is sometimes called a “poor man’s copyright.” There is no provision in the copyright law regarding any such type of protection, and it is not a substitute for registration.

Is my copyright good in other countries?
The United States has copyright relations with most countries throughout the world, and as a result of these agreements, we honor each other's citizens' copyrights. However, the United States does not have such copyright relationships with every country. For a listing of countries and the nature of their copyright relations with the United States, see Circular 38a, International Copyright Relations of the United States.

Can I copyright my website?
The original authorship appearing on a website may be protected by copyright. This includes writings, artwork, photographs, and other forms of authorship protected by copyright. Procedures for registering the contents of a website may be found in Circular 66, Copyright Registration for Online Works.

Can I copyright my domain name?
Copyright law does not protect domain names. The Internet Corporation for Assigned Names and Numbers (ICANN), a nonprofit organization that has assumed the responsibility for domain name system management, administers the assignation of domain names through accredited registers.

How do I protect my recipe?
A mere listing of ingredients is not protected under copyright law. However, where a recipe or formula is accompanied by substantial literary expression in the form of an explanation or directions, or when there is a collection of recipes as in a cookbook, there may be a basis for copyright protection. Note that if you have secret ingredients to a recipe that you do not wish to be revealed, you should not submit your recipe for registration, because applications and deposit copies are public records. See FL 122, Recipes.

Can I copyright the name of my band?
No. Names are not protected by copyright law. Some names may be protected under trademark law. Contact the U.S. Patent & Trademark Office, 800-786-9199, for further information.

How do I copyright a name, title, slogan or logo?
Copyright does not protect names, titles, slogans, or short phrases. In some cases, these things may be protected as trademarks. Contact the U.S. Patent & Trademark Office, 800-786-9199, for further information. However, copyright protection may be available for logo artwork that contains sufficient authorship. In some circumstances, an artistic logo may also be protected as a trademark.

How do I protect my idea?
Copyright does not protect ideas, concepts, systems, or methods of doing something. You may express your ideas in writing or drawings and claim copyright in your description, but be aware that copyright will not protect the idea itself as revealed in your written or artistic work.

Does my work have to be published to be protected?
Publication is not necessary for copyright protection.

Can I register a diary I found in my grandmother's attic?
You can register copyright in the diary only if you own the rights to the work, for example, by will or by inheritance. Copyright is the right of the author of the work or the author's heirs or assignees, not of the one who only owns or possesses the physical work itself. See Circular 1, Copyright Basics, section “Who Can Claim Copyright.”

How do I protect my sighting of Elvis?
Copyright law does not protect sightings. However, copyright law will protect your photo (or other depiction) of your sighting of Elvis. File your claim to copyright online by means of the electronic Copyright Office (eCO). Pay the fee online and attach a copy of your photo. Or, go to the Copyright Office website, fill in Form CO, print it, and mail it together with your photo and fee. For more information on registration a copyright, see SL-35. No one can lawfully use your photo of your sighting, although someone else may file his own photo of his sighting. Copyright law protects the original photograph, not the subject of the photograph.

Does copyright protect architecture?
Yes. Architectural works became subject to copyright protection on December 1, 1990. The copyright law defines “architectural work” as “the design of a building embodied in any tangible medium of expression, including a building, architectural plans, or drawings.” Copyright protection extends to any architectural work created on or after December 1, 1990. Also, any architectural works that were unconstructed and embodied in unpublished plans or drawings on that date and were constructed by December 31, 2002, are eligible for protection. Architectural designs embodied in buildings constructed prior to December 1, 1990, are not eligible for copyright protection. See Circular 41, Copyright Claims in Architectural Works

Can I get a star named after me and claim copyright to it?
No. There is a lot misunderstanding about this. Names are not protected by copyright. Publishers of publications such as a star registry may register a claim to copyright in the text of the volume [or book] containing the names the registry has assigned to stars, and perhaps the compilation of data; but such a registration would not extend protection to any of the individual star names appearing therein. For further information on copyright protection and names, see Circular 34, Copyright Protection Not Available for Names, Titles, or Short Phrases
