Trademarks are established through use in commerce. So long as we continue to offer a thing called "zsh" for download, "zsh" is our trademark. Registration can help but is not required. > Copyright law might come into play because of the license terms, but > because zsh assigns copyrights on the individual files to the > individual contributors, it would be a serious headache to try to > bring a coherent claim. I'm not sure that is correct =E2=80=94 but IANAL so I can't speak with a= ny certainty. What I can say is that copyright law and trademark law aren't the same t= hing, and that zsh doesn't "assign" copyrights on individual files =E2=80=94 i= t doesn't have those rights to begin with. > This is probably one of the factors behind other OSS projects deciding= > to join consortia like the Apache Foundation or Mozilla. I can't speak of Mozilla, but the Apache Software Foundation doesn't require copyright assignment; they only require a copyright _license_ (an ICLA [1]). They do register trademarks for some of their project names, but not all. Cheers, Daniel [1] https://www.apache.org/dev/new-committers-guide.html#cla
