Hasn't IBM release a pile of it's patents for use (or at least stated
they won't sue) to OSS projects? If so, is this patent covered by that
"amnesty"?
Simply ignoring patents because "there is a patent for everything" is a
recipe for disaster. Companies like MS are running out of ways to tear
open OSS and they are certainly not above (below?) suing the heck out of
OSS projects for patent infringement.
What's needed is reform in the USPO. Call you congress (wo)man and
complain, but don't flaunt the law; you will lose.
