Remedy for Violation of Open Source License May Be in Contract, not Copyright
Jacobsen v. Katzer, No. C06-01905 JSW, 2007 U.S. Dist. LEXIS 63568 (N.D. Ca. August 17, 2007)
This little case about model railroad software addresses a debated issue in the open source community: on what basis can open source creators sue people who misuse their work. This case seems to suggest breach of contract is an available remedy, but not copyright infringement. The case also deals with copyright law preemption.
Plaintiff developed model train software made available on this online community. Plaintiff’s work was subject to a standard open source software license permitting members of the public to make copies, distribute and make derivative works, providing they gave credit to the creators. Plaintiff alleged that defendants used plaintiff’s software to develop and fraudulently patent their own software for model train enthusiasts. Plaintiff sued on a number of counts and moved for a preliminary injunction to enjoin defendants from willfully infringing plaintiff’s copyrighted materials.
The court first held that plaintiff’s claims of unfair competition and unjust enrichment were preempted by federal copyright law, as both counts dealt “exclusively” with the misappropriation of plaintiff’s copyrighted files, a subject matter within the Copyright Act. To survive preemption the state claims must protect different rights than copyright rights. The state claims here did not add the required “extra element” to change the nature of the action or the rights secured under copyright law.
The court then denied plaintiff’s injunction, stating that plaintiff’s claims sounded in contract, not copyright. The court held that, implicit in a non-exclusive license like this one was a promise not to sue for copyright infringement. That is not to say that a licensor may never sue for copyright infringement, but they may only do so when the licensee exceeds the scope of the license. In this case, the license, like all open source licenses, was intentionally broad, closing the door to a copyright claim.
