Plant Patent cpcs

I found that more than 13,000 plant patents on have been assigned cpcs! (cpc=Cooperative Patent Classification) I don't recall seeing the memo saying that plant patents could receive cpc assignments. This page is asking patentsview for data on those same plant patents. The results below show that patentsview does not send back uspcs or cpcs as they should. I've turned the patent numbers into links that will bring up the patent on where these fields are present. Apparently the patentsview people did not receive the cpc memo either!
