Canon patent for 28mm F1.4L and 35mm F1.4L lens with resin elements

Canon patent referring to a 28mm F1.4L and to a 35mm F1.4L lens. The interesting point: the patent mentions “resin lenses”. Wait, what? A plastic lens on a Canon L lens?

It’s not “plastic”, obviously. It’s resin, and, according to the patent, such a lens element should have less dispersion and less aberrations.

I wonder if and when such a lens may go to production.
