IBM

IBM is one of the biggest lobbyist for software patents (along with Microsoft), as can be seen in their amicus brief for the EPO's software patent consultation in April 2009.

IBM is however against business method patents (such as the patent at the heard of the in re Bilski case in the USA).

For information about IBM's 2008 amicus brief to the Supreme Court of the USA regarding Bilski, see Fake representatives of free software#IBM.
