"This work is protected under the copyright laws of the United States.  No reproduction, use, or disclosure of this work shall be 
permitted without the prior express written authorization of the copyright owner.  Copyright ©1994 - 2013 by LAWCHEK, LTD."

Copyright is a form of intellectual property protection over "original works of authorship."  Works of authorship include literary, musical, dramatic, choreographic, pictorial, graphic, sculptural, audio, visual and architectural works.  A copyright owner has the exclusive rights: (a) to reproduce the work; (b) to prepare derivative works; (c) to distribute copies of the work to the public; (d) to perform the work publicly; and (e) to display the work publicly.  17 U.S.C. §106. 

            Protects expression only.  Copyright only protects expression, not the underlying idea.  Thus, under the copyright law, an idea is free to copy, but the expression of the idea is protected.

            Automatic protection.  In the U.S. today, copyright protection is automatic for both published and unpublished works.  Any work that is recorded, written or otherwise "fixed in tangible medium of expression" after January 1, 1978 is automatically protected from the moment of its creation.  In contrast, patent protection does not arise until a patent is granted by the Patent and Trademark Office.  Registration of a copyright provides certain benefits, but is not required for copyright protection to exist.

            Limitations.  The exclusive rights provided by copyright have some limitations.  One major limitation is that "fair uses" can be made of copyrighted works without the copyright owner’s permission.  17 U.S.C. §107.  Another limitation takes the form of a "compulsory license" under which certain limited uses of copyrighted works are permitted upon payment of specified royalties and compliance with statutory conditions.

            Term.  A copyrighted work is ordinarily given a term enduring for the author's life, plus an additional 50 years after the author's death.  In the case of a work made for hire, the duration of copyright will be 75 years from publication or 100 years from creation, whichever is shorter.              

            Notice.  For works first published on and after March 1, 1989, use of the copyright notice is optional, though highly recommended.  Before March 1, 1989, the use of the notice was mandatory on all published works.  Copyright notice informs the public that the work is protected by copyright.  The notice of copyright contains the symbol © (or the word "Copyright" or "Copr"), the year of first publication of the work, and the name of the owner of copyright in the work.  For example, © 1996 LAWCHEK, LTD.

            Governing law.  The purpose of the copyright laws is "to promote the progress of science and useful arts, by securing for limited times to ... inventor the exclusive right to their respective writings and discoveries."   Art. I, section 8 of the U.S. Constitution.  Accordingly, Congress enacted the Copyright Statute at 17 U.S.C. § 101 et seq.  Federal courts have exclusive jurisdiction over copyright matters.  28 U.S.C. § 1338.
