What is the length of time a utility patent lasts from the filing date?

A utility patent, once granted by the USPTO, provides protection for a duration of 20 years from the earliest claimed filing date. This period allows the patent holder exclusive rights to make, use, sell, or distribute the patented invention, effectively safeguarding their intellectual property and incentivizing innovation. After the 20-year term, the patent generally enters the public domain, allowing others to use the invention without permission or royalty payments.

The other options reflect shorter periods that do not accurately represent the current legal standard for utility patents. For instance, a 10-year duration is not applicable as it is well below the established term, while 15 years and 25 years also do not align with the 20-year protection period set by U.S. patent law. Understanding this duration is crucial for inventors and businesses as they navigate the patenting process and consider the commercial viability of their inventions.
