Explanation
A patent is used to protect intellectual property while requiring the owner to provide the public with working details of an invention or a process. A patent grants the owner the exclusive right to make, use, or sell the invention or process for a limited period of time, usually 20 years. A trademark is used to protect a name, symbol, logo, or slogan that identifies a product or service. A trademark grants the owner the exclusive right to use the mark to distinguish their product or service from others. A license is used to grant permission to use intellectual property under certain terms and conditions. A license does not transfer ownership of the intellectual property, but only grants limited rights to use it. A license can be revoked by the owner if the terms and conditions are violated. A copyright is used to protect original works of authorship, such as books, music, movies, or software. A copyright grants the owner the exclusive right to reproduce, distribute, perform, display, or create derivative works based on their original work.
