It is interesting to note that Lucasfilm still occasionally waves Cease and Desist letters around: in July they wrote to a company that makjes highly dangerous portable lasers.
According to Lucasfilm, said laser "is designed to look like a lightsaber from Star Wars."
The latest news is that Lucasfilm have retracted the Cease and Desist, because, apparently, "the media and public has come to realize that Lucasfilm would never endorse or license a highly dangerous product such as your Arctic Pro Laser."
You can read the original cease and desist letter here (via). Thanks to Narrative for the news tip.
