As a good friend of mine would say: well, see what happened was...That's what the owners of the patent for cryogenically probably wanted to say when a court ruling invalidated their patent. Turns out that to get a patent, you have to disclose prior sales, which is part of the reason that they lost it. The makers of Dippin' Dots sold a similar product to over 800 customers a year before they applied for the patent.
Dippin' Dots lost its patent in 2007, and it has two main rivals (even though I've never heard of wither one): MiniMelts and MolliCoolz.
