You don't need to ask for permission to write a book if the country you're residing in has freedom of speech. Be careful with including material from third parties, though, you often need permission for that. Other than that you want to be clearly either fiction or fact, true fiction or untrue facts can cause trouble. That being said: patents are published so no problem there. Some companies only provide information under NDA or forbid reverse engineering in their license, so if you publish such information they can get upset. Even more so if you publish trade secrets. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
