Did Tamron design the Zeiss Batis 85mm lens?

The Japanese site Egami spotted a brand new Tamron patent for a 85mm f/1.8 optical stabilized lens for Full Frame mirrorless system. We don’t have yet the official lens element design of the new Zeiss Batis but it could be that the Tamon design has been sold to Zeiss for the Batis?

Anyway, what really matters is that the lens performance is terrific no matter who actually designed it. And it’s quite common in the lens world to buy lens design from other companies. So this doesn’t diminish the value of the lens. Or, what do you think about it?
