Docter claims they own the patent rights to the process and that Leica uses it under license, but this was disputed a year or so back on the LUG. The problem Leica had with the production of the initial 1.4/25 Aspherical Summilux led to their adoption of the blank-molding process. I had never heard of a Tamron involvement.
