@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,

This begs the question of whether precocious rootstocks like Newroot1, Krymsk1, Pixie, Citation and Clare (Corette series) break the internode rule and allow us to speed up the breeding cycle.

Does anyone have any direct experience grafting seedlings onto precocious rootstocks?

>>It's interesting they state 77 to 122 internodes. In my days I had tested a highly productive nashi pear on quince-C. I set two of the said quince clones beside each other, grafted juvenile root sprouts from nashi 2-2-40 to one and flowering wood to the other. The tallest at 5 feet was the one with juvenile wood and made the tree with flowering wood look significantly small. They stood beside each other for years with no capacity of the tall juvenile tree to produce flowers.

Crankyyankee, I don't know if that observation would carry over to other species.  In the article, they are just looking at apple seedlings.  I've been seeking information regarding whether losing the juvenile (non blooming) trait is due to issues such as carbohydrate storage in stems, or something epigenetic, or what else.  Something tells me it is epigenetic, because you can graft a fruiting stage scion and get bloom more quickly than grafting a juvenile stage scion.

I've read that grafting seedlings to mature trees can speed up fruiting.  I don't have experience with that.  I did graft some variegated plum or pluot, grown from purchased farmers market "pluots" that were deep red, throughout the fruit.  Unknown variety and pollenizer.  Those have pretty variegated leaves, bloom very early, and have never fruited.  I keep them for novelty and because I grew them.  It's been about six or seven years.  They are top grafted onto other plum trees.

Why would wikipedia never alert to type-1 or type-2 genetics in the red flesh lineup? Type-1 is a single locus that determines red leaf and flesh by other web resources and if your seedling to the left will stay constant red then what you put out is a proper assessment of the odds. I guess the bigger question is where, if any, you knew what color of leaf the red Redlove (TM) came of? 

It's a good strategy and love these ideas, so if it's legal we should do it more. It raises questions, so what about patented trees; okay to breed them while in an active patent status; aimed towards another use of the art? (etc.)

My guess is this is the same material that Phil Forseline talked about at the Leech gardens botanical show. We were introduced to new apples from wild overseas and others in his collections were offered out to researchers with red flesh and small crab-apple size. I can only speculate between the two types which were offered. So about improvements, I am glad you're picking that up! Columnar red-flesh high quality apples already sounds really great!  

Rooney,

As far as I can determine, Redlove® varieties are not patented.  I've looked and looked and looked to find it.  I think if they were patented, the nurseries would say so.  So would Lubera.  I have looked on google patent search, too.  However, even if they were, you can still grow seedlings, which are each genetically unique and are not clones of their parent.  You can't clone patented varieties, but you can grow their seedlings.  The exception is if a gene is patented, ie, genetically engineered varieties.  You can't propagate GMO plants because it's the gene that is patented.   However, these apple varieties are not genetically engineered.  They do have a trademark, but that is not the same thing.  I can't use their trademark name for progeny, or for clones, and I wont.   Again, I'm not a lawyer so I'm open to someone who is.

This info is from the US Patent office: "Grant of a plant patent precludes others from asexually reproducing, selling, offering for sale, or using the patented plant or any of its parts in the United States or importing them into the United States."  I bolded the "asexually".  Seed hybridization is not asexual.  The website further states "Asexual reproduction is the propagation of a plant without the use of fertilized seeds to assure an exact genetic copy of the plant being reproduced. Any known method of asexual reproduction which renders a true genetic copy of the plant may be employed. "  Again, my bolding.   Sexual reproduction, on the other hand, combines the genes from both parents, resulting in plants that are genetically unique, and not at all an exact genetic copy of either parent.

As for the genetics of the red flesh trait and red leaf (stem, cambium) trait, I don't know.  I read somewhere, red skin and red flesh are under separate genetic control.   For example, Redlove® all seem to have red skin AND red flesh (and red coloration in young leaves on my trees, and red-ish flowers).  On the other hand, Airlie Red Flesh has green or, if really ripe, translucent yellowish skin with some red flesh color showing through.  I forget if Airlie Red Flesh has red cambium too.  I'm speculating but I think the red flesh trait is from Malus niedzwetzkyana.

(From the wikipedia I guess I should use ® instead of TM.  Depends on where and whether the trademark is registered.  I  try very hard to respect these issues.  Either way, that is trademark, not patent.  I  wont call any seedlings by those names).  

All of thus prompted me to see if my Redlove® apple trees have red leaves all year.  Actually, the only photo I have shows that just the new growth was red.  The older leaves were green.  Sometimes my brain is a sieve!  This is May 2020, Redlove® Era®  Based on this, I bet the seedlings leaves will green up as they mature, too.  Time will tell.

You know about patents. Thanks for being so meticulous.

Now that it's straight that this breeding of a patented cultivar isn't stealing, that we know you are breeding leaf curl resistant peaches like your " designated as cowlitz peach ", and short internode peaches make for stylish trees that are easier to prolong due to the ease of coverage against a few months of PNW winter rains, then you must contact me for free peach pollen. 

Let the PNW breeding begin. I will PM you now.

Daniel: I got your note about declining my offer of this pollen, thanks. Since it has curl resistance, short internodes, and blooms the same period of time as my part plum/peach/sweet cherry (ie. 'sugar twist', today 3-15-2021) then I think I will attempt a stylish short internode plum on the same. If it is to work at all it would take 2 more pure selective plum backcrosses.
