If you want to make your iPhone analogy applicable to this situation, we would only be able to buy used or NOS iPhone 2G's and nobody else would be allowed to make an all touchscreen smart phone. There's a point when too many intellectual property rights hurts a market. All the iPhone spinoffs have pressured apple to keep innovating and keep their prices down (but only slightly because they're apple

). That argument makes even less sense since the iPhone is still in production - GT isn't getting any more money out of triple tri track frames. The dilution of their market value doesn't matter much to GT now since they don't even offer them anymore.
