I haven't been able to follow discussions of this case closely, but from the samples that I have seen, the dominant narrative seems to be that the similarities between Samsung's devices and those of Apple are like the similarities between the Great White Shark and the Orca: of course they're sleek & hydrodynamic, of course they have dorsal fins, of course they have sharp, pointy teeth — they are filling similar niches, and given enough time evolution can make sea-dwelling, top-predator mammal look like a sea-dwelling, top-predator fish. But now it looks like the designers of the orca have been studying the shark in excruciating detail. If these design elements of touch-screen phones are so obvious and natural, then why do deep, point-by-point comparisons like this?
