Sometimes patent holder enter into initial deals with manufacturers and then can't lower the royalty price for other manufacturers. Even if they'd make more from higher volume, the initial manufacture might be serving high-end customers and doesn't want other manufactures entering the market at a lower price. So they refuse to agree to a lower patent royalty even though it would save them money. It's counterintuitive, but rationale under certain circumstances. This is pure conjecture for the e-ink patent on my part, but I've seen it first hand for other products.
