History is the science that studies human actions over time. Invention refers to anything invented and the act of inventing (new ideas or existing objects). The person who dedicates their time to these discoveries is the inventor.
When a person creates something new without previous examples, this invention is a significant contribution to human knowledge and can be protected by a patent.
A patent is a right granted by the government to an inventor, allowing only them to make, use, sell, and import their invention for a certain period, usually 20 years. In return, the inventor must explain how their invention works so others can learn from it. Patents help protect new ideas and encourage innovation, allowing inventors to earn money from their creations.
