Why search patents?

Searching patents during design can help you:

  • Determine if your design idea is novel
  • Identify areas you may need to design around to avoid infringement
  • Find inventors (technical experts) with whom to collaborate
  • Find inventions that are free to use because of expired or unissued patents
  • Monitor emerging designs in a technology area that may not be published elsewhere
  • Identify key companies in a technology area who may be interested in your design.
