What is a patent?
A Patent is an exclusive monopoly granted by the Government to an inventor over his invention for limited period of time. Patent is a form of intellectual property.
Why are patents necessary?
The patents encourage further and continuous innovations that help to improve the quality of human life.
Why should one patent his invention?
Since a patent confers legal rights concerning the exploitation of an invention, it allows the owner the best opportunity to profit from the invention by preventing others from copying it. An inventor does not need a patent in order to exploit an invention; but without a patent the inventor would not be able to prevent others from copying the invention. The patent gives the holder, the right to decide as to who can use the patented invention for the period in which the invention is protected. The invention cannot be made, used, distributed or sold without the authorization of the patent owner. The patent owner is also conferred the right to transfer, sell, mortgage or license the patent, just like any other personal property.
What are the criteria adopted for grant of a patent to an invention?
To qualify for patent protection, an invention must be new, useful and non-obvious.
■Novelty: An invention must not be in the public domain before the patent applicant invented the invention. The Indian Patent Office will not grant a patent on an invention that was publicly used or "on sale" - by anyone, including the inventor -- before the inventor filed a patent application.
■ Usefulness: An invention must be useful for some purpose, and must possess industrial applicability for the grant of patent. Utility is not presumed, but must be disclosed as part of the patent application.

Publicly disclosed inventions, including patented inventions, are known as prior art that can be cited in the Examination Report. Publicly disclosed inventions are considered prior art irrespective of where or in what form the public disclosure occurred. Identical or similar inventions that others publicly disclose anywhere in the world before an inventor files his patent application - known as prior art - may prevent the inventor from obtaining patent protection because the invention would not be considered novel.
What is a claim? What is the difference between an independent claim and a dependent claim?
Patent claims establish the boundaries or scope of an invention, including the best mode to make, use or sell it. A dependent claim relies upon an independent claim and includes all the limitations of the independent claim. The independent claims will be the broadest protection that you will have and the dependent claims are typically drafted to add further limitations and specifics to your invention.
