A patent provides how many years of protection?

• A. 5 years.
• B. 50 years.
• C. 70 years.
• D. 20 years for a novel or working part.

Answer: (D)

Patents last for 20 years from the filing date. This term is meant to give the inventor exclusive rights to make, use, or sell the invention for a set period, after which the invention enters the public domain. The option stating twenty years for a novel or useful part matches this standard duration. The other times listed don’t fit how patent protection is timed: five years is far too short to incentivize developing new technology, while fifty or seventy years align more with other forms of intellectual property like copyright in many systems. Remember, the 20-year term is from filing and is subject to maintenance fees.
