They only own the stuff that originated elsewhere in titles they've since bought up (MACH 1, MACH 0, Ant Wars, Monster, Thirteenth Floor, Johnny Red, Charley's War, Star Rider, the Wildcat strips, etc), but I think if they were determined they might make a case for one or two things like BloodFang, which might have been the subject of a lawsuit if it hadn't originated from the same company that published Flesh - though at a mere 120-odd pages of material, I can't see Rebellion being that bothered.
