The case was one of trademark infringement. The plaintiff argued that he had sent a copy of his screenplay "Space Pets" to LFL in 1979, which detailed a group of alien beings called Ewoks. Of course, LFL has an office firewall in place so that GL doesn't come into contact with unsolicited material; besides, the judge decided that the two concepts were far enough removed from each other as not to constitute trademark infringement. In short (pardon the pun), the case was laughed out of court.
