@Rooney, the leaves and flowers of that Redlove(TM) Calypso(TM) are dark red with a greenish cast, similar to the seedling.  The flowers are dark pink, and the cambium is red.  It's as if one dipped the whole plant into some red dye.  I think Bud9 is also like that, as is Redfield apple.  It may come from a shared Malus niedzwetzkyana ancestor, which if you can spell without looking it up, you are a lot smarter than me.

I am not a lawyer, but I read that it's fine to grow seeds from patented trees.  It is not OK to propagate patented trees vegetatively.  Also, it's not OK to propagate or grow seeds from genetically engineered plants, because then it is the gene that is patented.  I only know of a few  apples that are genetically modified, and those are gene silenced, not gene added, to stop browning reaction (Arctic (TM) series).  I don't know if those are patented.

As far as I have been able to determine, Redlove series trees are not patented.  They do have copyrights.  Either way, if you grow a seedling from them, it is genetically different from the parent so is not patented and it would be inappropriate to refer to them by the trademark name.

It will be a long tine before I know if my seedlings amount to anything.

If interested, here is a link to an article about growing apple seedlings from juvenile nonfruiting stage, to adult fruiting stage.  They state that is at about 77 to 122 internodes. They give some options to encourage earlier maturity.

Shortening Juvenile Stage for Apple Seedlings.

I have noted that horizontal branches tend to bloom earlier, so I wonder about grafting to a bearing tree and bending the growth to horizontal,
