First: You probably do not want to know if it _is_ the case. In the US
you cannot assume that a patent will be deemed valid by the courts
just because the USPTO has granted the patent. If you are infringing a
patent and the courts find it valid, you may be liable for damages. If
you knowingly infringed the patent damages will rise (I seem to
remember with a factor of 2).

Second: I have searched and found nothing.
