A recent post has prompted me to ask this? I heard once that Cannon has a patent on an aspherical grinding process that impeeds Nikkor from producing relatively inexpensive asphericals. Has anyone else heard about this?

Please note: I love my Nikkors. I love my Nikon. I've never owned a Cannon. I'm not trashing anyones cameras. DON't flame me!
