A patent gives its owner the right to prevent others from making, using, importing or selling the invention without approval. Before such a right is granted, there obviously is a rigorous check on whether the process or product is inventive (i.e. isn't obvious), novel (hasn't been anticipated in any published document) and industrially applicable (possesses utility). It involves a search of the database of the intellectual property regulator of India to check whether there exists an object or invention that is the same as or similar to applicant's invention. This is also known as a prior art search.
