FOSS devs can collect damages from license violators

“Robert Jacobson, the developer behind the open source Java
Model Railroad Interface (JMRI) project, finally prevailed in a
long-running open source software license enforcement lawsuit
against Matthew Katzer, the owner of a company that sells
commercial model train software.

“Katzer initially threatened Jacobson and JMRI with a patent
infringement lawsuit in 2005, and demanded hundreds of thousands of
dollars in licensing fees. Upon investigating Katzer’s claims,
Jacobson was surprised to discover that Katzer had misappropriated
significant amounts of JMRI code, using it without attribution in a
commercial software package. Jacobson retaliated against Katzer’s
patent suit by filing a copyright infringement suit.”
