Conducting a Patexia Prior Art Search


1 . Choose a contest.

2. Familiarize yourself with the question, patent (if any), latest date for prior art and any specific requests in the contest.

  • Carefully read over and highlight key points in the contest description and/or patent.
  • Consider outlining the question and/or patent for yourself.
  • If given a specific patent
  • consider making a claim chart to break down the patent’s claims and track how they relate to references you find in your search. For more information, see this claim chart guide and this example.
  • Review the patent file history.
