No he didn't, actually. He can't actually use that name.

Ehhh, well, technically that may be true, but maybe with enough money and lawyers and an incompetent judge that might not be good enough. I recall this small mini company, Paulson Games, that made "bio swords" that were obviously--albeit not exclusively--intended for Tyranids, and GW sued them. GW's evidence against the company, from what I recall, consisted of a forum post. Or something. Anyway, long story short, the lawsuit failed, but it had to be annoying to deal with.

So I guess the moral of the story is, better safe than sorry. At least I figure that's why WMS doesn't just use the names of the characters instead of sound-alikes.
