I remember learning about Frontenac a while back and hearing that it was not 
patented, but that Frontenac Gris was.  I feel like I heard this at a 
workshop given by one of the researchers from U of M who was involved in 
breeding it and I'm pretty sure he was the one who found Frontenac Gris and 
patented it.  Now I'm seeing TM next to it at many nurseries and charges for 
royalties.  Some have it and some don't.  Are they confusing it with Gris or 
did someone patent Frontenac?  Any help would be appreciated. Dan
