Note that restrictions imposed by this patent (and possibly others)
exist independently of and may be in conflict with the freedoms granted
in this license, which refers to copyright of the program, not patents
for any methods that it implements. Both copyright and patent law must
be obeyed to legally use and redistribute this program and it is not the
purpose of this license to induce you to infringe any patents or other
property right claims or to contest validity of any such claims. If you
redistribute or use the program, then this license merely protects you
from committing copyright infringement. It does not protect you from
committing patent infringement. So, before you do anything with this
program, make sure that you have permission to do so not merely in terms
of copyright, but also in terms of patent law.
Please note that this license is not to be understood as a guarantee
either. If you use the program according to this license, but in
conflict with patent law, it does not mean that the licensor will refund
you for any losses that you incur if you are sued for your patent
infringement.
