Are you serious? Do you really think a new plastic polymer was invented for your smart phone bumper?

I bought one for an iPod. It was $30. My impression was, this might be the most over-priced, marked-up product I ever purchased. Ever. It was clearly < $1 worth of generic keychain plastic. Clearly you believe there are $29 worth of IP and licensing costs to justify the price.
No, if there were $29 of licensing costs, then they'd be selling at a loss, since bringing such a product to market involves a lot of other costs, as well.
