A patent is a legal right granted to an inventor to protect their invention from being used, copied, or sold by others without permission for a specific period of time. In exchange for this exclusive right, the inventor must fully disclose the details of their invention to the public.
Patents are a form of intellectual property that incentivize innovation by ensuring inventors can benefit from their ideas while encouraging the dissemination of knowledge.
How Patents Work
A patent gives the inventor exclusive rights to a new and useful process, machine, product, or composition of matter, or an improvement on an existing invention. These rights are granted by a governing authority, such as the United States Patent and Trademark Office (USPTO) in the U.S.
-
Duration: Most patents last 20 years from the date of filing for utility and plant patents. Design patents typically last 14–15 years, depending on the filing date.
-
Territorial Scope: Patents are generally valid only in the country or territory where they are granted. Inventors must apply in each country where they seek protection.
-
Disclosure Requirement: Inventors must provide detailed documentation, including descriptions, drawings, and claims, to explain how the invention works.
