If you have deep and rich portfolio, there are high chances that your patents can be infringed by your competitors or rivals. Now, to showcase how your patent has been infringed? You need to map your claim systematically and that’s where the Evidence of Use chart comes into play.
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. Evidence of Use showcases the evidence that speaks about your patent claim.
This produces data that supports the claims of your patent. Evidence of Use provides an accurate representation of selected assets and infringers. Evidence of Use mapping is also helpful during negotiations for patent licensing, pre-litigation research and in patent transaction opportunities to create a strong value for the patent.
The patent-to-product mapping chart is used to determine how closely the product matches the claim.
Patent-to-Standard mapping entails mapping patent claims to the relevant text of a standard, to demonstrate standard-essential patents (SEP).
Thorough evaluation of the patent in question, including its prosecution history, scope, and specification. 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.
