Red Chalk Group provides a broad range of patent infringement analysis services. Claim chart drafting, sometimes referred to as patent mapping, is the frequently the first step in developing a patent infringement case. Red Chalk Group can assist you in developing a patent claim chart to enhance your case. We have extensive in-house capabilities to perform the technical evaluation of products and services to look for evidence of use of patented technology.

When evidence of use is found, claim charts are prepared to document the findings. Our highly trained technical experts begin by thoroughly reviewing the patent claims and then identifying potential infringing products (or services). The claims are then carefully mapped to the device or service via technical analysis, considering the patent specification, publicly available material, and expert knowledge. Patent claim mapping and the resulting infringement claim chart can then be utilized to better understand the strength of the patent and the basis for the infringement case.
