I believe it's far from moot:
http://iis-liquidation.ch/en-us/Sales-completed/Brands (have a look at the first pdf file)
Even when in liqudation, there is a successor trustee (remember Rodinal).
So far no evidence that Ilford brand is owned by the Harman Technology company.
We could probably argue about the subtleties of the difference between owning a trade mark and owning a "royalty free, fully sub-licensable, exclusive, irrevocable worldwide license ... to use the Trade Marks" within the field of black and white photographic materials and chemicals and apparatus for processing and printing on or through the same.
Much of that is quoted exactly, but I have paraphrased a bit to aid in readability.
If you prefer, however, I'll amend my earlier statement to read:
"More accurately, manufactured by Harman Technology Ltd., the owners of the Kentmere trade mark, as well as being the owners of a royalty free, fully sub-licensable, exclusive, irrevocable worldwide license to use the Ilford trade mark within the field of black and white photographic materials and chemicals and apparatus for processing and printing on or through the same.
Whew!
