"They don't think it's a threat. However, a trademark must be actively protected, or else it's lost forever. Since Apple is hugely dependent on its picture branding, they have no choice but to prosecute."
Utter codswallop. Whilst Apple are required to defend their trademark, this does not pass the "moron in a hurry" test (the test applied for "passing off" of trademarks in England and Wales), and thus defence of the mark is not required (I'm assuming the US has similar provisions/requirements).
