There seem to be three parts: 1) Are PRC and Apple morally wrong for enforcing and not fighting patent claims? 2) Should patents work in a way that incentivizes PRC and Apple to behave this way? 3) Irrespective of (1) or (2) what can be done?
(1) The answer to this is somewhat ambiguous for any company with investors. Sure, I want my companies to behave in morally responsible ways. On the other hand, there are hundreds of other ways to save and improve lives. If we wanted the companies we invest in to maximize quality of life improvement we would get much further providing vaccinations or microloans to the third world where owning an iPad is as much a pipe dream as winning the lottery (per unit money, energy, whatever). If we want larger public access to scientific advances, perhaps we should fund more public science? Or, we should change the way patents work (2).
(2) This to me seems like a very reasonable question. Aside from patent wars that might hurt your favorite smartphone os vendor, there are real concerns. Drug companies are incentivized to create substances and methodologies that drastically improve the quality and duration of lives in both first and third world countries. On the other hand, intellectual property protection for drugs (until they become generics) does cost lives. But we shouldn't forget just how powerful those incentives are. All the awesome research done in university laboratories (one of which I work in) is nothing without the ability to take a drug from "lab-rat plausible" to "market-ready". Certainly patents don't exist to facilitate personal wealth. But just because they do generate wealth doesn't mean that their intended goal has been forgotten, short-term losses notwithstanding.
Even if we answered (1) and found PRC or Apple to be morally culpable, it misses the larger issue: if society feels that this girl, or others who benefit from patented technology should be allowed to use it, someone's got to pay. Either it's the companies and their investors (the obvious point: not just rich folks), or it's taxpayers through some form of state-sponsored licensing (edit: or some other state-funded mechanism). It's tremendously easy to blame only Apple and PRC (even if they did deserve it). It's a lot harder to put your money on the line, so that families like this one can solve a heartbreaking problem.
