What is a prior art search?

Before proceeding with the process of filing a patent application, it is advisable that a prior art search for the invention may be conducted. A prior art search helps in discovering the current state of the field of technology to which the invention relates and thereby helps in determining the novelty of the invention. This is done by searching through global patent databases and non-patent literature to determine whether the product or process for which a patent application is being considered is already in public use or a patent has been applied for or granted to it in India or any other jurisdiction.
