| name = IBM Public License | author = IBM | version = 1.0 | copyright = IBM | date = August 1999 | OSI approved = Yes | Debian approved = Yes [1] | Free Software = Yes [2] | GPL compatible = No [2] | copyleft = Yes | linking = Yes }} The IBM Public License (IPL) is a free software / open-source software license written and sometimes used by IBM. It is approved by the Free Software Foundation (FSF) and described as an "open-source license" by the Open Source Initiative. The IPL differs from the GNU General Public License (GPL), in that it places the liability on the publisher or distributor of the licensed software code. According to IBM, this is to facilitate commercial use of open-source software, without placing the contributor at a risk of liability.{{Citation needed|date=June 2007}} Proponents{{who|date=July 2016}} of the IPL note a clearer definition of responsibility for software code than that of the GPL. The IPL is incompatible with the GPL because it contains restrictions not included in the GPL. According to the FSF, "This is a free software license. Unfortunately, it has a choice of law clause which makes it incompatible with the GNU GPL."[2] The IPL differs from the GPL in the handling of patents, as IPL terminates the license upon patent disputes. Examples of software projects licensed under the IPL include Postfix, OpenAFS, and the now-unmaintained Jikes compiler for Java. See also{{Portal|Free and open-source software}}
