Except that logos are copyrightable while names are not, if I remember correctly. Both are of course trademarkable.
You can copyright names in a given context. For example you can copyright boost so that no software library but your own may call itself "boost". It becomes a brand. But someone can come up with clothes called "Boost" and you can't prevent them from using your name unless you copyrighted the name of boost for clothes as well (or the usage will harm you somehow, as you can guess it's to who's going to get the best lawyers). Copyrights have a limited reach, you need to pay for copyright per country and per class. *Anyway...* Drafting a bit out of topic here and I'd like to give more context to my initial question. I've got a very limited marketing knowledge, but I do know that generally speaking you want to control how your name is used and talked about, hence my question about the usage policy of the "powered by boost". You may want to craft the logo license in such a way so that you can force people using the logo in a way you dislike to cease and desist (for example spamming software saying "powered by boost"). Ah maybe I'm just nitpicking... -Edouard __________ Information from ESET NOD32 Antivirus, version of virus signature database 4849 (20100208) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
