What legal protection covers the expression of ideas, excluding certain types of concepts and formulas?

The correct choice is Copyright, as it specifically protects the expression of ideas rather than the ideas themselves. Copyright law provides rights to creators of original works, such as literature, music, and art, which allows them to control the use and distribution of their creative expressions. This legal protection encourages creativity by providing an exclusive right to the author or creator to benefit from their work.

While many types of intellectual property exist, Copyright uniquely focuses on the tangible expression of thoughts, ensuring that other individuals cannot reproduce or distribute these works without permission. It is important to note that while a copyright protects the way ideas are expressed, it does not extend to the underlying concepts or formulas, which is why certain types of ideas remain unprotected under copyright law.

Understanding this distinction is crucial as it highlights the boundaries of copyright protection, ensuring that while original expressions are safeguarded, the broader ideas and concepts behind them can still be freely utilized by others, allowing for innovation and progress in various fields.
