The 25% rule revisited and a new investment-based method for determining FRAND licensing royalties

This paper starts with briefly discussing the 25% rule and the argumentation for and against it. The paper continues with developing a new investment-based method for determining FRAND licensing royalties, a method not only applicable to one-to-one bilateral licensing deals but also to multilateral deals with multiple license sellers and multiple license buyers. The paper ends with discussing limitations and generalizations, opening up for further research.
