They look good, but I could not find any detailed info on site about the scrubbers they are selling? Like recommended pumps, GPH, lights, size of screens, etc.
The original Walter Adey patent 4,333,263 from 1980 that you might be referring to has expired, yes. There were related ones even before that, that are of course expired too. And there are other related ones since then that are either issued or pending.
