What is a patent?

Answer 1

A patent is a set of exclusive rights granted by a state to a patentee (the inventor or assignee) for a fixed period of time in exchange for the regulated, public disclosure of certain details of a device, method, process or composition of matter (substance) (known as an invention) which is new, inventive, and useful or industrially applicable.

The exclusive right granted to a patentee in most countries is the right to prevent or exclude others from making, using, selling, offering to sell or importing the claimed invention. The rights given to the patentee do not include the right to make, use, or sell the invention themselves. The patentee may have to comply with other laws and regulations to make use of the claimed invention. So, for example, a pharmaceutical company may obtain a patent on a new drug but will be unable to market the drug without regulatory approval, or an inventor may patent an improvement to a particular type of laser, but be unable to make or sell the new design without a license from the owner of an earlier broader patent covering lasers of that type.

The term "patent" originates from the Latin word patere which means "to lay open" (i.e., make available for public inspection) and the term letters patent, which originally denoted royal decrees granting exclusive rights to certain individuals or businesses.
