Detailed explanation-1: -Exclusive rights: Patents provide you with an exclusive right to prevent or stop others from commercially exploiting an invention for twenty years from the date of filing of the patent application.

Detailed explanation-2: -Can patents be renewed? U.S. patents issue for fixed terms and generally cannot be renewed. A U.S. utility patent has a term of 20 years from its earliest effective, non-provisional U.S. filing date.

Detailed explanation-3: -A U.S. utility patent, explained above, is generally granted for 20 years from the date the patent application is filed; however, periodic fees are required to maintain the enforceability of the patent.

Detailed explanation-4: -After a patent has been in place for 20 years for utility patents and 14 years for design and plant patents, the invention becomes part of the public domain. This means the invention no longer has patent protection and is no longer off limits, so anyone can make, use, or sell the invention without infringement.
