This listing mentions they have a Pentax HD coating. I wonder if it's just BS, or is it actually licensed.

Doubt it, that's probably acronym expansion in action or something like that.

In the context of a movie (video) lens, HD relates to the compatibility of the lens with the particular format (anything greater than standard definition). Presumably Pentax has a copyright on the HD term in the very narrow context of lens coatings. The ebay seller is undoubtedly mistaken. The lens looks to have a decent coating, but not similar to any I recall seeing on any Pentax lenses.
