> I can point at the 3D printing industry as an example. Several years ago, some critical patents expired, resulting in a burst of innovation Yes, I've read that as well from magazines but I must admit I've never checked the journalist claims or seen what critical patent expired that made the 3d printing industry flourish. Because it could just have well been access to open source designs that only flourished in the 2000s but I know nothing about 3d printing so I'm just speculating and making it clear that I'm doing that. So when it comes to posts here about my own industry which I feel I know pretty well, I see claims that seem farcical to me so I've been asking, which critical patent does EInk have? So far, I've not had any answer. > And yes, if I were an investor in display technology, I would be quite hesitant to touch electronic ink style displays due to patents. If I was your boss, I'd again ask a simple question. Which patent? If you can't identify it, then do you think it is possible it is an incorrect belief based on perhaps a lack of understanding of the display industry?
