Your going to have a hard time alleging that the word Dredd is a (C) infringement when no design rights (the font) or graphic image is being used. Judge Dredd would be a delimited trademark, Dredd without an illusion to the comic or even comics per say (ie COMICS ICONS #1: DREDD) very unlikely to be one at all (regardless of registering, you would have a hard time advocating to an adjudicator that the term Dredd covers all contexts).
