Mgt. should make an estimate of the "addressable market" for ceramic separators and then come up with an approximate valuation of their 100+ patent(s) for what is the class of all ceramic separators...should be very easy to estimate give the CAGR of EV's and the likes of materials handling etc. and other unknown areas that are going Li-on, SS Metal, I would say there has to be a big "B" or more behind the number.
