Mwilson, This cross is not officially registered with RHS as of yet. You can search for yourself here:
The International Orchid Register / RHS Gardening
If you go to the Ihsin website (link here)
IHSIN BIOTECHNOLOGY INC.-ORCHID?FLASK?PLANT?PHALAENOPSIS?MERICLONE?NURSERY-ProductDetail
They just list the parents used for the cross, usually a good indication as well that it has not been named.
Often times a seller or his supplier will give their own name to crosses to make them more sellible, its a very common occurance with plants coming from Taiwan.
You can always try contacting IHsin directly to aquire the name if one has been given to this cross recently.
BTW: very pretty blooms you have there!

Forgot to add that this name could also be a provisional name from IHsin that just has not been accepted yet by the RHS!
