A patent, in simple terms, is defined as the legal construct that will give a grant to the patent owners to uniquely practice or manufacture the invention in the approved nation for a certain period. Right now, the time limit is 20 years from the patent application filing date. In the USA, patents are granted for discoveries that are not only useful but also need to be non-obvious and novel in the prior art light. The non-obvious and novelty of the invention is dependent on the prior art search. The prior art refers to any data publicly available in any form to the patent application filing.
