What are the characteristics of patent patent?

A patent is a legal right granted by a government that gives an inventor exclusive control over the use, production, and sale of their invention for a specified period, typically 20 years. Key characteristics include novelty (the invention must be new), non-obviousness (it cannot be an obvious idea to someone skilled in the field), and utility (the invention must have practical utility). Patents can cover various types of inventions, including processes, machines, and compositions of matter. Additionally, a patent requires a detailed description of the invention, enabling others to understand and reproduce it once the patent expires.
