Unsigned memorandum describing the current four-step process for making RG-244, a silica-coated asbestos material, and comparing it with the claims of FMC's German patent 1,567,517 and U.S. patent 3,458,393. It concludes that neither patent's process claim is infringed. It also concludes that the U.S. article claim is not infringed because RG-244 has silica added, whereas the patented material has MgO removed. A copy of the German patent claims is attached.
