Plant patents expire and are not renewable. Here in the U.S. I believe they are 15 years, but that number is worth checking.
Next you have the issue of where the plant is
from. Like most fruiting banana cultivars, SH-3640 was not developed in the U.S.
Also with fruiting bananas, esp. tetraploids you have the problem of viable pollen and compatible cross-breeds. Tetraploids are essentially mules.
