The answer is below
Step-by-step explanation:
Patent is a term that describes a governmental grant or legal right to inventors of an intellectual property, to refrain or stop others from making, using, selling or importing their invention to and from other country.
Patent system is useful and beneficial because of the following reasons:
1. It allows an inventor the right to stop others from copying, manufacturing, selling or importing individual's invention without the person's permission. This will surely encourage invention from other people, which will lead to more technological advancement in the country.
2. It gives an inventor protection for a pre-determined period. This helps to refrain competitors from competing with the inventor, and in turn, leads to profit maximization for the inventor.
3. It also allows the inventor to license patent for others to use it or can sell. This can be considered as a great source of revenue for inventor's business, by collecting royalties from a patent they have licensed, often in a combination with a registered design and trade mark.
