Trademark: A trademark protects brand names and logos used on goods and services. It's like your secret burger recipe being known as 'Your Name's Famous Burger' - no one else can use that name for their burgers.
Copyright: This is a law that protects original works of authorship such as books, music, film, and art. If you wrote a song about your famous burger, copyright laws would protect others from using your lyrics without permission.
Patent: A patent is an exclusive right granted for an invention. If you invented a special machine to cook your famous burger perfectly every time, you could patent that machine so no one else could copy it.
