What is the essence of patent law?

The essence of patent law is to encourage people who enjoy inventions and technologies to make their inventions and technologies public for the whole society to know and enjoy, and to give inventors legal exclusive rights for a certain period of time. After inventions and technologies are recorded in the patent specification and published in the patent bulletin, people with the ability to invent can continue to study the existing technologies in society, improve and innovate better inventions and technologies, and benefit the public more.
