- gwern 11y agoPatents run out. Swarovski presumably is keeping it as a trade secret, which is riskier but probably far more profitable in the long run (especially if they've managed to keep the core secrets this long).
- eonw 11y agowithout their amazing marketing ability, having the same glass really isnt that useful, so i guess trade secret does make more sense in this light.
