You, and many others here in this thread to be fair, are making a bad assumption. As explained back when the original news broke, Apple had several reasons to suspect that the clock design might be available for them to use without a license. It appeared that it might have been a government-held IP, which in many countries is public domain. If privately held, it might be so old as to have had any applicable copyright protection expire. The design might be sufficiently generic that copyright or patent protection might not have excluded their use. Even if Apple's use was infringing, the fact that Apple was giving the clock app away for free with the hardware might have given rise to a judgment of fair use. Any number of things.
Apple's attorneys probably knew all this, and the SBB attorneys knew it too. They all sat down at a table and figured out a number that would allow SBB to garner some value from their asserted mark without the risk and expense of losing it in litigation, and Apple gained usage certainty with the same risk and expense abatement. Win-win. All these assumptions about who TOOK this and STOLE that, it's all amateur hour. This isn't the Samsung case where internal emails said "See Apple's IP, which we know is theirs and not ours? We need to copy that as closely as possible. Mum's the word."
