Claim Charts
A claim chart is the most precise instrument in patent analysis — a structured, element-by-element mapping of patent claims against products, processes, or standards. Prism IP's claim charts are built to withstand scrutiny in licensing negotiations, litigation, and regulatory proceedings.
What Is a Claim Chart?
A claim chart maps each element of a patent claim — word by word — against the corresponding feature of a product or process. For infringement to exist, every element of at least one claim must be present in the accused product. A claim chart makes that case (or refutes it) with documentary precision.
Claim charts are used in licensing negotiations to demonstrate the strength of a patent position, in litigation to support or defend infringement allegations, in SEP (Standard Essential Patent) proceedings to establish essentiality, and in portfolio transactions to evidence the value of specific patents.
The quality of a claim chart is determined by the technical depth of the analysis and the care with which evidence is sourced and documented. Prism IP's team combines engineering expertise with legal precision to produce charts that hold up under the hardest questioning.
Types of Claim Charts
Mapping patent claims against an accused product or process to build or defend an infringement case. Used in litigation preparation and enforcement strategy.
Demonstrating to a potential licensee that their product practises specific patent claims — the persuasive foundation of any licensing negotiation.
Mapping standard essential patents against the relevant technical standard (3GPP, IEEE, etc.) to establish or challenge essentiality claims in FRAND licensing disputes.
Mapping prior art references against patent claims to support invalidity arguments — used in IPR proceedings, oppositions, and litigation defence.
Analysing competitor patents against your own products to identify exposure — the defensive side of claim chart analysis.
Evidencing the coverage of a patent portfolio for M&A, divestiture, or licensing programme purposes — supporting valuation with documented claim coverage.
