Welcome to the RoyaltySource® IP Data Guide

At RoyaltySource®, we maintain a database of intangible property licenses that report a royalty rate. These benchmarks are used in valuation, license negotiations, and transfer pricing assignments. Here in the RoyaltySource IP Data Guide, we will offer some insight, frequently asked questions, and proposed solutions offered over the past 20 years from RoyaltySource.
What is the difference in rates/values between exclusive and non-exclusive royalty rates charged in technology/software industries?
The subject of a discount or premium on royalty payments for "exclusive v. non-exclusive" licenses has been addressed by Tom Varner has written about this. You will note from the article the following paragraph:

"Some patent licenses include a royalty reduction provision if the license is converted from an exclusive basis to a nonexclusive basis. Among patent licenses that specify a royalty reduction in the event that a licensor converts an exclusive license to a nonexclusive license (either by licensing to a third party or by entering the market itself), over two-thirds specify a royalty reduction of 50 percent." See Thomas R Varner, 2011. "An Economic Perspective on Patent Licensing Structure and Provisions, " Business Economics, Palgrave Macmillan;National Association for Business Economics, vol. 46(4), pages 229-238, October.

As we travel through the database and read licenses Tom has captured what we also see.

Simple subtraction between exclusive and non-exclusive across licenses is not a very good measure. Remember that every clause in a license agreement has some economic value and impacts the royalty payment. So to attribute the difference to only exclusivity is likely misleading.
