IBM Public License


The IBM Public License (IPL) is a FLOSS license, developed by IBM, which has been ratified by the Open Source Initiative as being compliant with their Open Source Definition, and by the Free Software Foundation.

The license is broadly similar to, but incompatible with, the GPL. Some of the noteable features of the IPL are:
  • It places liability on the publisher or distributor of the licensed program. This intended to facilitate commercial use of programs without placing people who contribute to the software at risk of liability.

  • The license requires that commercial distributors indemnify all "upstream" originators of their legal costs for lawsuits brought about by users of the software, some people argue that the license exposes small distributors to potentially excessive and unlimited legal costs.

  • It has certain requirements regarding patent licenses. These requirements are the principal reason for incompatibility with, the GPL.

  • The IPL license terminates upon patent disputes.
