Utility/Design Patent
The reason why the "rounded corners" argument keeps being brought up by some, is because we are old enough to remember the "look and feel" lawsuit that Apple brought against Microsoft.
Apple tried it on with Microsoft, and failed. They resurrected the spectre of that long dead lawsuit when rounded corners was mentioned (either directly, or indirectly) in their lawsuit against Samsung.
But if you want to talk about nobody copies Samsung phones, you might want to think again about your Fruity firm. Nobody is copying Apple phones either, they're copying Sony and Samsung phones.
