Is this all just tied in with something like doctors writing brand-name prescriptions, and the brand name just gets these minor pointless "improvements," but enough to diverges away from what the generic is so it can't be easily substituted? I just feel like there's always a step missing in the usual simple descriptions of evergreening I see. If on the other hand there's a significant improvement, it seems like that's really something that should be getting patent protection. If the "improvements" are so minor as to be irrelevant then I don't see how this is a real impediment to a generic. The new patent can't cover the subject matter of the old patent, as its automatically prior art, so only the improvements are covered by the new patent. So far I'm following along.īut the narrative is, this locks out generics somehow. The story is, a drug company seeing their patent expiration come up, makes some small improvement and patents that, getting them a new term. I've never quite gotten the problem with evergreening. The real problem is that nobody wants to put millions into making displays when they could get higher ROI from putting it into another hot AI/ML or internet service company. You can see this pattern repeated with companies like Mirasol. Startups show up but can't get the billion or so that's needed to get to scale. They can't solve cheap large panels because that would require solving yield issues which again becomes a matter of scale. What I know is that EInk can't get to the lower cost pricepoint without solving the scale problem which means getting an order for millions of displays. I've been to SID and other display conferences and the real problem is physics and also lack of funding. To be frank, I suspect those who make that comment aren't actually directly involved in the industry. I ask the simple question of which patent is blocking, and I get lazy answers like patent thicket. ), looks like their earliest patents are from 1998, so those should be expired already.Įverytime this topic of EInk comes up, people on HN seem to claim there's a patent thing. Shame, although not a big loss as an estimated cost for that was near the five figure ballpark and the current consumption was astronomical, sometimes triggering the protection of the power supply on certain images.

I would have loved to have it as a PC monitor so I tried building an HDMI interface controller for it with an FPGA but failed due to a lack of time and documentation.

My God, was the picture gorgeous and sharp. One day E-ink sent over a 32" 1440p prototype panel with 32 shades of B&W to show off. Tough, some of their tech is pretty dope. So, when you see the high prices of e-paper gadgets, don't blame the manufacturers, as they're not price gouging, blame E-ink, as their displays make up the bulk of the BOM. With so much control over the IP and the entire supply chain and due to the broken nature of the patent system, they're an absolute monopoly and have no incentive to lower prices or to bring any innovations to the market and are a textbook example of what happens to technology when there is zero competition. In my previous company we had to reverse engineer their waveforms in order to build usable products even though we were buying quite a lot of displays.

Any research project or startup that comes up with a better alternative technology gets bought out or buried by their lawyers ASAP.Į-ink don't make the display themselves, they make the e-ink film, filled with their patented pigment particles and sell it to display manufacturers who package the film in glass and a TFT layer and add a driver interface chip, all of which are proprietary AF and unless you're the size of Amazon, forget about getting any detailed datasheets about how to correctly drive their displays to get sharp images. E-ink, the company, holds the patents of the pigment core tech that makes "paper-like" displays possible and strongarms the display manufacturers and the users of their displays to absolute silence.
