Copyright is a set of exclusive rights granted to the author or creator of an original work, including the right to copy, distribute and adapt the work. Copyright does not protect ideas, only their expression. In most jurisdictions copyright arises upon fixation and does not need to be registered. Copyright owners have the exclusive statutory right to exercise control over copying and other exploitation of the works for a specific period of time, after which the work is said to enter the public domain. Uses covered under limitations and exceptions to copyright, such as fair use, do not require permission from the copyright owner. All other uses require permission. Copyright owners can license or permanently transfer or assign their exclusive rights to others.
Initially copyright law only applied to the copying of books. Over time other uses such as translations and derivative works were made subject to copyright. Copyright now covers a wide range of works, including maps, sheet music, dramatic works, paintings, photographs, sound recordings, motion pictures and computer programs.
A copyright notice, either as symbol or phrase, informs users of the underlying claim to copyright ownership in a published work.
Copyright law is different from country to country, and a copyright notice is required in about 20 countries for a work to be protected under copyright. Before 1989 all published works in the US had to contain a copyright notice, the © symbol followed by the publication date and copyright owner's name, to be protected by copyright. This is no longer the case and use of a copyright notice is now optional in the US, though they may still be used as a deterrent against infringement, or as a notice that the owner intends on holding their claim to copyright.
A copyright notice or copyright symbol is an identifier placed on copies of the work to inform the world of copyright ownership. While use of a copyright notice was once required as a condition of copyright protection, it is now optional. Use of the copyright notice is the responsibility of the copyright owner and does not require advance permission from, or registration with the Copyright Office.
Because prior law did contain such a requirement, however, the use of a copyright notice or copyright symbol is still relevant to the copyright status of older works.
Copyright notice was required under the 1976 Copyright Act. This requirement was eliminated when the United States adhered to the Berne Convention, effective March 1, 1989. Although works published without copyright notice before that date could have entered the public domain in the United States, the Uruguay Round Agreements Act (URAA) restores copyright in certain foreign works originally published without copyright notice.

How Is A Copyright Symbol Useful
Use of the copyright notice may be important because it informs the public that the work is protected by copyright, identifies the copyright owner, and shows the year of first publication. Furthermore, in the event that a work is infringed, if a proper notice of copyright appears on the published copy or copies to which a defendant in a copyright infringement suit had access, then no weight shall be given to such a defendant's defense based on innocent infringement. Innocent infringement occurs when the infringer did not realize that the work was protected. The use of the copyright notice is the responsibility of the copyright owner and does not require advance permission from, or registration with, the Copyright Office.Correct Form For The Copyright Symbol
The notice for visually perceptible copies should contain all the following three elements:- The copyright symbol © (the letter C in a circle), or the word "Copyright," or the abbreviation "Copr."
- The year of first publication of the work. In the case of compilations or derivative works incorporating previously published material, the year date of first publication of the compilation or derivative work is sufficient. The year date may be omitted where a pictorial, graphic, or sculptural work, with accompanying textual matter, if any, is reproduced in or on greeting cards, postcards, stationery, jewelry, dolls, toys, or any useful article.
- The name of the owner of copyright in the work, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner.
Example: copyright © 2002 John Doe
The © or "C in a circle" notice or symbol is used only on visually perceptible copies.refer : http://inventors.about.com/od/copyrights/a/CopyrightNotice.htm
