Patents historically provided exclusive rights to inventions. Which pair is a classic example?

• A. The Lightbulb by Edison and The Telephone by Bell.
• B. The Radio by Marconi and The Lightbulb by Edison.
• C. The Telephone by Bell and The Lightbulb by Edison.
• D. The Internet by Tim Berners-Lee and The Computer.

Answer: (C)

Patents give inventors exclusive rights to profit from their invention for a period in exchange for public disclosure. This creates a temporary monopoly, allowing the inventor to control who can make, use, or sell the invention and to earn returns on the investment in developing it.

The pairing of the telephone by Bell and the lightbulb by Edison is a classic example because both inventions were protected by strong patent rights in their time. Bell’s patent on the telephone gave him exclusive rights to manufacture and license the device, shaping the early telecommunications market. Edison’s patents related to the incandescent light bulb and related improvements gave him control over production and sales, a powerful position in electrical lighting for years. Together, they illustrate how patent protection can grant significant market power to inventors, encouraging innovation while also enabling licensing and legal actions to enforce those rights.
