Patent Searching

A guide to patent searching for engineering students

Welcome to the Patent Searching Guide!

Do you have an idea for an invention? There are several possible reasons you may want to do a patent search:

  • Patentability - has my invention or similar inventions been patented? (checking "prior art" for "novelty")
  • Freedom to operate - if already existing, has the patent on this invention expired, meaning others are free to manufacture it? 
  • Mining - are there companies who might be willing to manufacture or market my invention?
  • State of the art - what are the most recent patent applications granted in the area of my invention? (to determine existing solutions and potential competitors)

Whatever your reasons, this guide will help you get started.
