Nope. They want to charge anyone who can decode mp3s:

This patent-only license is needed in case the mp3 software is developed in-house or licensed from a third party. (as opposed to using the Fraunhofer mp3 libraries or the Coding Technologies mp3PRO libraries)

They've also talked in the past about trying to extract money from the Ogg Vorbis folks because their patents are so generic as to basically cover any form of music compression that involves psychoacoustics.
