And that's precisely the point for Apple.
> The problem is that many of Apple’s patents focus on look, feel, and design, which means they can be worked around, as in the cases mentioned above. As a result, Apple could have a hard time securing lasting, sticky restrictions that would permanently prevent its competitors’ products from being sold in individual markets, let alone worldwide.
And Apple doesn't care because that's not the point.
Despite the Jobs quote saying he wanted to sue Android out of existence, Apple does not really want to drive Android (nor other competitors) itself into oblivion, Apple wants people to stop copying their design. They want to force the copycats to differentiate, if not innovate.
