They would have at least owned the trademarks to Granada, Carlton, and their subsidiaries at the time the merger occured in 2002, as well as UTV (which they are still using, of sorts) and Channel which were acquired later. That would include LWT.

However they would never have owned the trademarks to the companies that lost their franchises prior to 1992, like Thames, TVS, TSW etc. (ATV might be an exception to that, but I’m not sure on that one, as while I’ve seen it suggested that it’s parent company ACC held on to the ATV brand when Central was created, I’ve also seen it suggested Carlton acquired that at a later date. Someone here will know better on that one).
