Evidence of Use Chart (EOU)

Imagine having the power to prove the uniqueness and value of your intellectual property with confidence and precision. Our mission is to turn that vision into reality. With our cutting-edge tools and expertise, we empower inventors and businesses to gather, document, and analyze the critical evidence needed to safeguard/ defend their IP rights.

This is where the Evidence of Use chart comes into play, with mapping your claim systematically against the product/service. Evidence of Use serves as your navigational tool to prove violation of your IP Rights.

Evidence of Use: An Overview

The EOU chart, through patent-to-product mapping, determines the degree of similarity between the product and the patent claim, showcasing the evidence that speaks about your patent claim.

Evidence of Use provides an accurate representation of selected assets and infringers. Such evidence is highly useful during patent licensing negotiations, pre-litigation research, and patent transaction opportunities, adding significant value to the patent.

Types of EOU Charts

1. Patent-to-Product Mapping
