What is the term of a patent issued by the United States Patent Office? Video Transcript

The question is how long is a patent's term? The term of a patent is 20 years from the filing date at the US application. About 15 years ago, the term was different. It was 17 years from the date of issuance of a patent. But today it is 20 years from the date of filing. It is almost the same thing because it usually takes three years to get a patent issued and so the date of enforceability of the patent is 20 years from the filing date and after that time, anybody can make and use the invention. It becomes dedicated to the public domain.
