<human>:  What is the difference between copyright and trademark law?
<bot>: The difference between copyright and trademark law is that copyright law primarily protects the expression of ideas, while trademark law is used to protect brand identities and symbols. Copyright law grants exclusive rights to creators of certain works to reproduce, distribute, perform, and display those works, while trademark law grants exclusive rights to a unique symbol, text, logo, or other mark to identify and distinguish a product or service.
