Patents are irrelevant - if you think OLEDs don't have any patents then I have a bridge to sell you. The real problem is that E-Ink is a niche product that lacks economy of scale, because LCDs do everything an EPD can do and more. I don't know if it's been patented, but E-Ink's recent Gallery 3 screen is pretty amazing, they got multi-dye color screens to refresh fast enough to use in an e-note. That's insane, that's an order of magnitude reduction! It might actually make color e-notes a viable product category.
