And I responded with this (curious for informed feedback):

I just read it. I can't believe this patent was granted. If I'm reading it correctly, it's a patent for an old trick used by every OS and video game ever made. Basically, don't redraw things that aren't in view, and only redraw the bits of things that are in view.

Anyway, I can't see how this is applicable to React, as it really isn't how the v-dom works at all. The v-dom isn't about failing to draw clipped items. The v-dom is about diffing two trees and only updating changed items.

Am I totally off base here?

Welcome to a larger world. The bulk of patents in the US seem ridiculous.

Nope. Software patents are basically bullshit and I'm glad I don't live in a country where they pose a direct threat to companies.

Thank you, you made me comprehend why all software patents are nonsense.
