Apple's mobile phone language Swift has some sort of "optionals chaining" that Apple finds novel enough to patent.
From the discussion, it appears Apple is intentionally using an Apache 2 license to ensure that access to this feature remains freely available. (Insert obligatory IANAL disclaimer.) Any Soylentils care to weigh in?

Yeah, well, both The United States Court of Appeals for the Federal Circuit and the US Patent Office disagree with you on that. The former keep disagreeing with Supreme Court decisions as well. Good luck getting any of it to stick, and in the mean time look forward to hugely expensive and lengthy court cases.
