What is Patent ?
A patent is a legal document granted by a government authority of a country that provides an inventor with exclusive rights to an invention for a limited period. This exclusive right allows the inventor to control the use, sale, or manufacturing of the invention, preventing others from making, using, selling, or importing it without the inventor’s permission. In essence, a patent serves as a reward for inventors, encouraging innovation by providing them with a temporary monopoly over their creations. To obtain a patent, inventors must disclose their invention in detail, enabling others to understand and replicate it once the patent expires. The typical duration of patent protection varies by jurisdiction but is commonly around 20 years from the filing date.
What is Invention?
An invention is a novel and non-obvious creation or discovery that introduces a new process, product, system, or method that offers a solution to a specific problem or satisfies a particular need. Inventions are the result of human creativity, ingenuity, and innovative thinking. They represent advancements or improvements over existing technologies or methods and often contribute to the progression of various fields, including science, technology, medicine, and industry.
For an idea or concept to qualify as an invention, it should be original, not obvious to someone skilled in the relevant field, and it must be capable of being reproduced or applied in a tangible form. Inventions can range from tangible devices or gadgets to intangible processes, methods, or formulations. The recognition and protection of inventions are often facilitated through legal mechanisms such as patents, which grant inventors exclusive rights to their creations for a specified period, encouraging innovation and rewarding inventors for their contributions to society.
Criteria for Patentability
Determining the patentability of an invention involves assessing it against three fundamental criteria, as outlined in the Committee Reports accompanying the 1952 Patent Act and reinforced by the Supreme Court in the Chakrabarty case. While the general principle allows for the patent consideration of “anything under the sun made by man,” the invention must meet the following key requirements:
- Novelty: The invention must be new and different from existing prior art. It should not have been publicly disclosed, used, or described before the filing date of the patent application. Novelty ensures that the invention brings a fresh and inventive contribution to the field.
- Usefulness: The invention must have practical utility or serve a beneficial purpose. It should offer a tangible, real-world application and demonstrate a clear and specific use. Usefulness ensures that the invention contributes meaningfully to the advancement of technology or addresses a particular problem.
- Nonobviousness: The invention must not be obvious to a person with ordinary skill in the relevant field. Even if the invention is novel and useful, it must involve an inventive step that goes beyond what would be considered obvious by someone familiar with the subject matter. Nonobviousness emphasizes the level of innovation and inventiveness required for patent eligibility.
By evaluating an invention against these three criteria—novelty, usefulness, and nonobviousness—one can ascertain its potential eligibility for patent protection. These criteria collectively aim to ensure that granted patents contribute significantly to human progress and innovation, fostering a balance between encouraging inventiveness and preventing the monopolization of basic ideas or natural phenomena.
