Why are patents important?
Patents legally identify inventions as belonging to the inventor. Patents are thus useful if:

  • You have invented something and want to make sure no one steals your idea.
  • To make sure your own idea is original and that is, no one else has already
    invented it.
  • To find information that doesn’t exist elsewhere in scholarly publishing.

Different kinds of patents:

There are different kinds of patents for different types of innovation generally they fall under three categories:

  1. Utility Patent
  2. Design Patent
  3. Plant Patent

These definitions and more can be found at The United States Patent and Trademark Office
