Speaking of high-end shoe designers, in 2011 it was fascinating to see the design company of Christian Louboutin try to stop the company Yves Saint Laurent from producing high heels with red soles, claiming that Louboutin was the originator of the red sole. Louboutin lost, and I was glad. He was not the first person to paint a sole, and I am wary of patenting a color, like Tiffany blue. Why should we grant that entire history to Louboutin and say there are no predecessors and should be no successors?
