I need a plan B...

I cannot legally get DMF in the states. There are three companies that hold patents.

I guess you mean products with DMF are blocked, because bare DMF, I call it the "Bill's" stuff, cannot be patented.
Can't you order from abroad? Or will that be stopped with customs?
Which would be strange, because you could order many things from abroad of which probably lots of them violate U.S. Patents.
Of course the last options is the expensive one. It can easily be financially impossible for you.
