Claim Chart
What is a Claim Chart?
A claim chart is an essential tool in patent infringement analysis, litigation, and patent validity assessments. It organizes complex technical information into a clear, tabular format, mapping each claim limitation or feature to corresponding evidence—such as product literature or technical documentation. This visual representation enables an objective assessment of whether an invention’s elements have been infringed upon, ensuring that every aspect of the patent is clearly understood.
Utility of a Claim Chart: How can claim charts be used in different scenarios?
It is believed that the sole purpose of a claim chart is to objectively establish an instance of infringement. However, a claim chart can also be used to determine/predict the success of an infringement case. Some of the other areas that necessitate the preparation of a claim chart are as follows:
Conducting competitive analysis: A claim chart may prove to be useful in assessing and evaluating competitors’ patents to gain insights into their innovation strategy and understanding any potential infringement.
Managing intellectual property risks: A claim chart can also help in comparing patent portfolios and product portfolios of two or more companies in order to identify potential risks, opportunities, and possibilities for strategic IP management.
Educating stakeholders: Claim charts can also be used to educate clients, stakeholders, and board members on the extent and relevance of patents, which would result in a better understanding of how exactly intellectual property affects the firm’s valuation.
Facilitating Patent Valuation: Claim charts can help in order to determine the implicit value of a patent by representing its scope and applicability to current technologies. This can prove to be useful for mergers, acquisitions, as well as investment decisions.
