What is the type of intellectual property protection for a valuable set of sales leads?

The correct response is trade secret because it is specifically designed to protect sensitive business information that derives economic value from not being generally known or readily ascertainable by others who could benefit from its disclosure or use. Sales leads, which comprise a valuable collection of potential customers and related insights, are often maintained in strict confidentiality to gain a competitive edge. By keeping this list private and taking reasonable measures to ensure its secrecy, a business can protect its unique business advantage.

In contrast, trademarks protect brand identities such as names, logos, and slogans; copyrights safeguard original works of authorship such as literature, music, and software; and patents provide exclusive rights to inventions or discoveries. None of these forms of protection address the unique needs associated with maintaining the confidentiality of sensitive business information like sales leads, which is why trade secret is the most appropriate choice here.
