A Visual Guide to Build Claim Charts

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 a first column of a table and evidence of use or evidence of publication are placed in a second column.

Erik Chmelar, Sr. IP Attorney at Dilworth IP, has created a visual guide that outlines best practices for creating claim charts capable of withstanding scrutiny in the board room and the court room. The infographic begins with basic principles applicable to most claim charts, then dives into advanced strategies that can lead to successful IP negotiations and litigations.


Refer to the visual guide for creating claim charts when faced with the following situations:

  • Determine essentiality of a standards-essential patent
  • Negotiate a patent license agreement
  • Invalidate a patent in an infringement defense
  • Assert a patent against an infringer
