EOU Chart

EoU Chart or Evidence of Use chart involves a detailed mapping of every element of patent claim(s) with the infringing (accused) product or a standard. EoU chart helps attorneys, lawyers and counsels in determining the infringement of the patent. Detailed Evidence of Use charts are helpful for licensing negotiations, pre-litigation research, and in patent transaction opportunities by establishing the value of the patent.

Broadly speaking there are two types of EoU charts:

1. EoU charts including Patent-to-Product Mapping
2. EoU charts including Patent-to-Standard Mapping.

As the name suggests, Patent-to-product mapping chart includes a mapping of elements of to the product and is used to ascertain the extent that the product reads on to the claim. Another type includes Patent-to-Standard mapping which includes a patent mapped on to the relevant sections of a standard, which in turn establishes infringement of the patent by products that are compliant to the standard mapped.

2. Analyzing and creating an exhaustive list of potential infringers.

3. Performing a thorough search on the identified companies and analyzing there product portfolios in order to find the best infringing product.
