you might want to check with the new patent laws -- they were changed in the last couple of years to coincide with the EU laws. Now, the clock on the patent starts when it is filed, not when it is granted, and it uses a first to file not first to invent doctrine. Part of that may have allowed non-commercial use because supposedly the idea is that you have to be able to build something as part of research -- to make it better (and generate follow-on patents). Just remember that IANAL and things have changed. Maybe there is someone out there that can comment on this sidebar, but the second poster (Viesturs?) has a valid point - people use this commercially and this is a clear violation.
