What is Evidence of Use?

Evidence of Use (EoU) helps patent owners identify potentially infringing products in the marketplace.  Our EoU charts patent claim elements to specific features of identified products and services, and provides an indication of the strength of patent infringement assertion.

When is EoU Charting Useful?

An EoU investigation is critical prior to embarking on a patent assertion campaign.  With the increased scrutiny being placed on patent owners to conduct infringement due diligence, an EoU investigation can help patent owners identify likely infringement versus potential infringement based solely on the claims as they read.

For patent investors, an EoU investigation may prove useful to understand the scope of infringement of a potential patent investment, and coupled with a Damage Modelling Assessment, may provide price guidance and an indication of future revenue potential of the patents at issue.
