Patents

What is a patent?

A patent is a right of ownership granted to a person by the government to exclude others from making or selling the claimed invention for a period of twenty years.

You have an idea for an invention, or have gone so far as to create a prototype. Before marketing your invention, you will need to determine if your invention has already been patented.

There are three main types of patents:

  • Utility: granted for the function of something that is mechanical, electrical, chemical, compositional, or any combination of these
  • Design: granted solely on the look or appearance of something
  • Plant: granted for unique, asexually reproduced plants
