From what we were told...50+ patents are still in for approval, and that number could be increasing. I don't think those are "obsolete" or "die casting". Foam and Sheets "shots in the dark" is just an opinion. We do not know how far they have gotten. Ohmic Heating?? May run into many issues in mass production. As well as the bonding techniques. Since they are in "arbitration" with VISSER, I doubt Steipp would say anything about the ENGEL agreements.
