Patents have been the most stringent kind of intellectual property rights where patent rights have been acquired for products which have minute levels of novelty & usefulness. Since 1980, the US Supreme Court opened doors for a rare kind of patent which were living micro-organisms who could be patented based on their subject matter. It was interesting and unique for the patenting of micro-organisms as the invention is alive, the invention can reproduce itself, and it is difficult to find the required essentials of a patent in a living organism.
