No Preliminary Injunction in Jacobsen Case

Those who follow the Jacobsen v. Katzer case know that it likely will have a significant on how US courts view open source licenses and what legal remedies are available when they are violated. The latest twist in the case, as reported on the Madisonian blog, is the decision of the US District Court for the Northern District of California to deny Jacobsen's request for a preliminary injunction. On its face, this decision might seem like a setback in the ability of open source licensors to ensure the terms and principles of the open source licenses are enforcable. However, my view is that the facts of the Jacobsen case are unique enough that this ruling will not significantly interfere with the efforts of other open source licensors to obtain injunctions.

For an excellent summary of the history of the Jacobsen case, including all the legal developments up to and including the Federal Circuit's ruling in August, please see Larry Rosen's excellent article "Bad Facts Make Good Law: The Jacobsen Case and Open Source". The particular fact of importance here is that Jacobsen requested a preliminary injunction based on Katzer's failure to comply with the terms of the Artistic License requiring the licensee to "duplicate all of the original copyright notices and associated disclaimers". Compare this to the Free Software Foundation's claims against Cisco, which include allegations that Cisco failed to comply with the GPL and LGPL obligations to distribute source code to modifications made by a licensee.

This distinction important because the types of harm likely to result from failure to distrbute source code are easier to identify and articulate than the types of harm from failure to reproduce copyright notices. Under the 2008 US Supreme Court opinion in Winter v. Natural Resources Defense Council, the Court elaborated on the well-accepted requirements for granting a preliminary injunction with a particular emphasis on the point that plaintiffs must show more than a mere possibility of harm, but must actually back up the claims of harm with meaningful evidence. Here is criteria cited by the Court for all US courts to use in deciding whether a preliminary injunction request should be granted:

"A plaintiff seeking a preliminary injunction must establish (1) that he is likely to succeed on the merits, (2) that he is likely to suffer irreparable harm in the absence of preliminary relief, (3) that the balance of equities tips in his favor, and (4) that an injunction is in the public interest." (I added the parenthetical numbers for easier identification in this blog post. The Court cites multiple cases on this point going back to 1982 including another 2008 opinion.)

Elements (2) and (4) are the most important for our purposes. With respect to element (2), meaningful harm from a failure to maintain proper copyright notices in publicly available software seems difficult to prove, and proving that the harm is irreparable is even more difficult. At worst, a recipient of the licensed software would receive the proper copyright notice after the software is distributed, but this would not result in any change in use or non-use of the software. By contrast, a failure to distribute source code could change the way a recipient uses the software, which is central to the purpose of the open source license.

Element (4) is particularly interesting as applied to open source software which, by its very nature, is intended to benefit the public. The public does not necessarily benefit from knowing whether a particular copyright notice is accurate, but the public cannot take full advantage of the software made available under an open source license unless it receives the actual source code.

Setting aside variations in application of the law across jurisdictions, a plaintiff is a more likely to be able to present evidence adequate to support a preliminary injunction when a case revolves around availability of source code under an open source license as compared to a claim of failure to adequately comply with copyright notice requirements. In my opinion, cases like the FSF's claims against Cisco are the types of cases we are most likely to see in enforcement of open source license terms. As a result, plaintiffs should not let the Jacobsen case discourage them from requesting preliminary injuctions, particularly when the plaintiff's claims are based on failure to distribute source code.
