I don't dispute any of what you just wrote. I know very well that many glass types used in older lenses are no longer available. Some used radioactive materials, other contain lead or arsenic, or used these and other hazardous materials in the manufacturing process. It is this very reason that caused Schneider to redesign their APO Symmar line a few years back.
Still, I have to point out that there are literally several dozen (if not 100s) of companies world wide offering a huge variety of synthetic optical adhesives. It is these companies, not Schneider, Rodenstock, Nikon or Fuji that own any IP associated with their products. As their goal is to sell as much of their product as possible they gladly sell to anyone who is willing to pay a fair market price for their products.
Likewise, many lens manufacturers buy their optical flats from other companies rather than make their own glass. Those suppliers will gladly sell their optical flats to anyone willing to pay their asking price. Yes, they may have patents on their proprietary products, but those patents are designed to keep their competitors from copying their designs and processes, not to prevent their customers from buying and using their products.
Rather than argue about why Michael can't bring a line of new ULF lense to market, I prefer to offer him all the encouragement and support I can. Where there's a will, there's a way - and Michael is very strong willed. Remember, it was Michael who convinced Kodak to sell TMAX 400 in ULF sizes last year after most photographers had given up on Kodak as a viable supplier of film in any size. As a result of the special order TMAX ULF film program last year, TMAX 400 was available in a whole range of sizes never before offered in this particular emulsion, and in some sizes Kodak hadn't cut in ANY emulsion in several decades. This after Kodak had discontinued all their conventional silver based photographic papers. Most people said that project that was impossible, too. Yet, here I sit with I have a freezer full of 7x17 TMAX 400 that would not exist if it weren't for Michael's tireless efforts. Bet against him if you wish, but don't be too surprised when you lose that bet. You may consider his latest venture a long shot, but frankly given his track record I'll be surprised if he DOESN'T succeed.
