Copyright is a legal right given by law of the country to the creators of original work for its use and trade. Copyright is just like an asset and is a form of intellectual property.
Any work that falls under categories like literary, drama, music, artistic film recording, painting, photography, poetry, audio recording or song which is new and unique is taken into account original work. To save the first work from infringement or theft, the work of art must be protected. A major limitation on copyright is that copyright protects only the first expression of ideas, and not the underlying ideas themselves.
It is important to record the copyrights granted to the owners and hence copyright registration is important to provide legal claim and rights to the owners for the protection of their work.
