What is the RAND royalty rate for a single essential patent?

Written by Menno Treffers

Assigning value to individual essential patents.

How would you split the royalty income between the owners of patents that are essential for using a standard?

Let’s assume for the moment that the patent owners and the users of the standard have agreed on a combined RAND royalty rate for the use of all essential patents. What is a reasonable royalty rate for 10% of these essential patents, or for a single essential patent? 

You could simply charge 10% of the RAND rate for all essential patents, but that assumes all essential patents are equal. There are, however, good reasons to differentiate between the value of individual essential patents:

  • An essential patent may be found invalid when challenged.
  • Some products may not infringe all essential patents.
  • Detection of infringement may not be feasible in practice for all essential patents.

Only patents that are valid and infringed will generate sustainable license income. The other essential patents play a marginal role. Manufacturers of products will want a license to reduce the risk of future claims, but they will pay far more for patents that have survived a validity challenge and are obviously infringed by the manufacturer’s products.

In an article on IPWatchdog.com, I compare different methods that have been tried to determine the RAND royalty rate for a subset of all essential patents, and suggest a method that is based on each patent’s contribution to generating license income.

Can patent owners block the use of a standard?

Developers of standards don’t like it when a patent owner blocks the use of their standard. The considerable effort that goes into developing a standard, typically hundreds of man-years, is wasted when that standard is not used.
