It is unclear what you mean. I already asked which specific patent needs to be canceled for your belief (hope?) to become true. I hope you don't give the same answer others here gave in the past. Which was: all of them. That just indicates a lack of understanding of the underlying physics of electrophoretics.

> Can the same be said about E ink? It's worse than literal paper for static images, worse than LCD for dynamic content. There is a niche for content that sometimes has to change, like on price tags, but those screens are significantly cheaper than what we're complaining about in this thread.

Yes. But how is that related to what I asked about? OP said it was expensive, and mentioned patents. I asked what OP meant by that. Because expensive based on what calculation? Just relative to LCDs? That's like saying a bottle of Chablis wine is more expensive than a bottle of coke. Sure. I agree 100% with that and I can only hope people understand why. It has nothing to do with patents.
