A federal court of appeals held in 2008 that an open source developer case sue for copyright infringement despite the breadth of the open source license. The closely-watched case recently settled, meaning that the opinion may well be cited for many years to come.
Plaintiff Robert Jacobsen holds a copyright to certain computer programming code that he makes available for public download for free pursuant to the Artistic License, an open source license.
Defendants Matthew Katzer and Kamind Associates, Inc. develop commercial software products for the model train industry and hobbyists. Defendants copied certain materials from Jacobsen’s website and incorporated them into one of their software packages without following the terms of the Artistic License. Jacobsen sued for copyright infringement and moved for a preliminary injunction.
