Copyright issues on web has now-a-days become the important issue. Unauthorized use of your copyrighted materials not only decreases your potential benefit but can also be harmful for your site's ranking in search engines. The search engines do not favor the duplicate content and can also drop the value both the original site and the site that has copied its content.

So therefore, how to protect your copyright is what important for you. Let's know something about copyright i.e. who can claim copyright, what work is protected and what is not and how to secure a copyright.

Who Can Claim Copyright?

Copyright protection subsists from the time the work is created in fixed form. The copyright in the work of authorship immediately becomes the property of the author who created the work. Only the author or those deriving their rights through the author can rightfully claim copyright.
In the case of works made for hire, the employer and not the employee is considered to be the author. Section 101 of the copyright law defines a "work made for hire" as:
1. work prepared by an employee within the scope of his or her employment; or
2. work specially ordered or commissioned for use as:

• a contribution to a collective work
• a part of a motion picture or other audiovisual work
• a translation
• a supplementary work
• a compilation
• an instructional text
• a test
• answer material for a test
• an atlas
  

If the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire.

The authors of a joint work are co-owners of the copyright in the work, unless there is an agreement to the contrary.

Copyright in each separate contribution to a periodical or other collective work is distinct from copyright in the collective work as a whole and vests initially with the author of the contribution.

What Works Are Protected?

Copyright protects "original works of authorship" that are fixed in a tangible form of expression. The fixation need not be directly perceptible so long as it may be communicated with the aid of a machine or device. Copyrightable works include the following categories:
1. literary works;
2. musical works, including any accompanying words
3. dramatic works, including any accompanying music
4. pantomimes and choreographic works
5. pictorial, graphic, and sculptural works
6. motion pictures and other audiovisual works
7. sound recordings
8. architectural works
These categories should be viewed broadly. For example, computer programs and most "compilations" may be registered as "literary works"; maps and architectural plans may be registered as "pictorial, graphic, and sculptural works."

What Is Not Protected by Copyright?

Several categories of material are generally not eligible for federal copyright protection. These include among others:

• Works that have not been fixed in a tangible form of expression (for example, choreographic works that have not been notated or recorded, or improvisational speeches or performances that have not been written or recorded)
• Titles, names, short phrases, and slogans; familiar symbols or designs; mere variations of typographic ornamentation, lettering, or coloring; mere listings of ingredients or contents
• Ideas, procedures, methods, systems, processes, concepts, principles, discoveries, or devices, as distinguished from a description, explanation, or illustration
• Works consisting entirely of information that is common property and containing no original authorship (for example: standard calendars, height and weight charts, tape measures and rulers, and lists or tables taken from public documents or other common sources)
  

How to Secure a Copyright?

Copyright Secured Automatically upon Creation

The way in which copyright protection is secured is frequently misunderstood. No publication or registration or other action in the Copyright Office is required to secure copyright. (See following note.) There are, however, certain definite advantages to registration. See "Copyright Registration."
Copyright is secured automatically when the work is created, and a work is "created" when it is fixed in a copy or phonorecord for the first time. "Copies" are material objects from which a work can be read or visually perceived either directly or with the aid of a machine or device, such as books, manuscripts, sheet music, film, videotape, or microfilm. "Phonorecords" are material objects embodying fixations of sounds (excluding, by statutory definition, motion picture soundtracks), such as cassette tapes, CDs, or LPs. Thus, for example, a song (the "work") can be fixed in sheet music ("copies") or in phonograph disks ("phonorecords"), or both. If a work is prepared over a period of time, the part of the work that is fixed on a particular date constitutes the created work as of that date.
