Which option describes the legal right to exclude others from making or selling inventions for a period of time?

• A. Piracy
• B. Population
• C. Price
• D. Patent

Answer: (D)

A patent gives the inventor the exclusive right to make, use, and sell an invention for a set period, preventing others from commercially exploiting it without permission. This protection creates a temporary monopoly that helps innovators recover their investment in research and development. The term is finite (often about 20 years from filing), after which the invention enters the public domain. Piracy means illegal copying or distribution, not a legal grant of protection. Population and price aren’t about exclusive rights to inventions. So this description points to a patent.
