Royalty Rate Determination

Abstract Courts require royalty rate calculations based on rigorous economic foundations. The licensing literature provides limited guidance for royalty rate determination, leaving appraisal report readers wanting a more tangible and objective lens through which to judge the credibility of royalty rate analyses. This article develops the standard, core model for calculating market royalty rates for intangible asset licenses where royalty rates are determined ex ante in the actual market, or ex post in a hypothetical market under a Market Value Standard. The model forms a consistent basis for performing and evaluating licensing royalty appraisals. Not being distracted with the question of how to combine the input values when calculating a royalty rate, the court can focus on understanding and verifying an appraiser’s calculations of the input variable values.
