[_feda_]

It's a potential point of conflict, but it's a pretty generic naming convention in my view and I'd be dissapointed to see that Zed has slapped a trademark on it. Even if he is building a brand around the name I don't see why he wouldn't be open to letting some other technical authors in under the same umbrella.

You don't understand how trademarks work. Zed automatically has a trademark on it. The question is whether or not he goes through the trouble of enforcing it. If he doesn't, he gives up the mark. Federally registering a trademark is really only to show the due process of protecting your mark.

Copyright is in the same boat.

Also, this is not nearly a generic enough name for it to be ineligible for trademark. It appears that Zed isn't interested in protecting this mark, but that doesn't mean he wouldn't have a case.
