Discover important prior art to support litigation.’s Patent Validity Search uncovers patents or other prior art, published before the earliest priority date of the target patent, which might render a granted patent invalid.  We deliver a full validity/invalidity search report, a claims-mapping chart, and electronic copies of any cited prior art.

You should conduct a Patent Validity search to:

  • Invalidate blocking patents
  • Provide deterrents to NPE demand letters
  • Complete due diligence regarding a patent, patent portfolio, or pending patent application

Our Patent Validity search includes:

  • Patents
  • Published patent applications
  • Non-patent literature

What we need from you:

  • Patent number and earliest priority date for the target patent
  • Specific claims you would like to invalidate
  • Any known related art (often the results of earlier searches)
  • Any additional information regarding litigation that could help guide the search strategy
