Claim Chart
What is a Claim Chart?

A claim chart is a visual representation of evidence showing how each claim limitation has been implemented by an infringing product or service. While formatting can vary, at a minimum a claim chart lists all relevant claim limitations in one column, and provides evidence (such as screenshots or text from product marketing material, developer documentation, FAQs, videos, network tests and/or photographs of the product or teardowns of the product) in another column against each of the claim limitations.

Great claim charts, such as those made by Copperpod, also provide detailed analyst comments explaining how the evidence shows that the charted product or service implements the claim limitation, and annotations highlighting the most important portions of the cited evidence.Claim charts are an essential artifact during any patent licensing or enforcement campaign, as it articulates the infringement theory in an easy to understand and difficult to refute format. Moreover, claim charts may evolve throughout a campaign, as new evidence is discovered during fact discovery, and the infringement positions become consolidated pre-trial.
