Evidence of Use
The Evidence of Use (EoU) chart is a comprehensive mapping of each element of the patent claim(s) to the infringing (accused) product or a standard. The EoU chart aids attorneys, lawyers, and counsels in assessing patent infringement. EOU charting (patent-to-product mapping) is considered to determine, how closely the product matches the claim of the subject patent.
Types of EOU Charts
- Patent-to-Product Mapping
The patent-to-product mapping chart is used to determine how closely the product matches the claim.
- Patent-to-Standard Mapping.
Patent-to-Standard mapping entails mapping a patent claims to the relevant text of a standard, to demonstrate standard-essential patents (SEP).
Our Approach
Thorough evaluation of the patent in question, including its prosecution history, scope, and specifications.
Product disassembly/tear down, source code analysis, and reverse engineering are used to identify products, processes, and services that exist within the same jurisdiction and are launched after the priority date of the patent.
Why Us?
Subject matter specialists are involved in the creation of the EoU.
EoUs with the right claim construction.
Access to commercial knowledge databases such as ITU, IEEE scholars, regulatory approval, teardown sites, document aggregator, standards, opposition list, anticipatory reference citation, press release, etc.
We use reverse engineering to enhance claim charts.
