A Visual Guide to Build Claim Charts

What Is A Claim Chart?

A good claim chart is like a Swiss Army knife – simple, efficient, and effective. A claim chart compares the limitations of a patent claim against a product, against other patents, or against various publications. Claim limitations are placed in the first column of a table and evidence of use or evidence of publication are placed in a second column. Patent claim charts are commonly used in patent infringement litigation and are an essential tool for both patent attorneys and judges.

Patent claim charts can also be used to:

  • Identify potential infringements: Patent attorneys can use patent claim charts to identify potential infringements of their clients’ patents. This can help to prevent costly infringement lawsuits.
  • Negotiate settlements: Claim charts can help negotiate settlements in patent infringement cases. This can help to resolve disputes without going to court.
  • Educate judges: Claim charts can be used to educate judges about the technical aspects of a patent claim. This can help judges to make informed decisions about patent infringement cases.
