Jacobsen v. Katzer/Kamind – Federal Circuit Upholds a Free Software License

By Zohar Efroni on

As reported by Lessig and others, the Federal Circuit vacated and remanded yesterday a ruling by the Northern District of California which denied the copyright claims of an open source software developer for violations of the Artistic License. This is a landmark decision which is likely to influence all types of free licensing, including Creative Commons licenses and the question of enforceability of copyright claims upon violation of free licenses in general. Here are four quick points on the decision:

Overall, it is a very interesting and important ruling. Before closing, here is my favorite quote (pp. 12-13) :

Copyright licenses are designed to support the right to exclude; money damages alone do not support or enforce that right. The choice to exact consideration in the form of compliance with the open source requirements of disclosure and explanation of changes, rather than as a dollar-denominated fee, is entitled to no less legal recognition. Indeed, because a calculation of damages is inherently speculative, these types of license restrictions might well be rendered meaningless absent the ability to enforce through injunctive relief.
