The interesting aspect of copyright protection is that it need not be registered with any authority to be protected under law. Secondly, it protects only the tangible expression of an idea and not an idea itself. This has led to many a litigation to settle the idea-expression dichotomy.
The Indian Copyright Act, 1957 protects original literary, dramatic, musical and artistic works and cinematograph films and sound recordings from unauthorized uses. Unlike the case with patents, copyright protects the expressions and not the ideas.
There is no copyright protection for ideas, procedures, methods of operation or mathematical concepts as such. In India, the duration of copyright for authors is life of the author plus 60 years after his/her death and for cinematograph films and sound recordings 60 years from the year of production. After the death of the owner, the rights pass on to his/her legal heirs.
