In the past, Qualcomm was infamous for high licensing fees.

However, part of the process of creating an open industry standard like 4G/5G is getting a legally binding commitment from the patent holders to license standards essential patents to all takers on "reasonable" terms.

> If the patent holder refuses upon request to license a patent that has become essential to a standard, then the standard-setting organization must exclude that technology.

So Qualcomm is still entitled to some money, but not nearly as much as they made back when there was no legal restriction on what they could demand.
