> the patent system isn't totally breaking innovation
This is like saying it wouldn't be so bad to be blind because blind people are able to live fulfilling and experience-rich lives. Yes, that is true, blind people do live rich and fulfilling lives, but this says nothing at all about the richness of the lives they could be living if they were not blind.
We have fewer than five large companies dominating the smart phone space. Let's ignore for a moment the fallacy that because smart phone innovation is occurring that therefore all innovation is a-okay. There are no small players in this space. This is like American car companies before Tesla and the other new electric companies got started. We know from experience that the domination of an industry by a few large players does not lead to innovation in the long term. It leads to tit-for-tat competition with little novel exploration of the space of possible products. These companies become conservative and self-concerned.
I think if you do any research into the current patent system, you will find it self-evident that the situation is untenable. Amazon holds a patent on "one-click ordering". They own a 20-year patent on the notion of only needing to click one button to make a purchase. Apple was just granted a patent on "searching across multiple databases simultaneously". The absurdity of the situation is apparent.
We are already in a period where large companies can use their patents to crush startups. It does not matter if the patent dispute is spurious and the startup clearly within their rights. Large companies with in-house legal staff can drown a startup by requiring them to fork out enormous quantities of money for legal representation in their self-defense. With a suite of patents, a company like Apple can bring suit after suit until finally the small company either loses one (these things are not decided by engineers or experts in patent law, they are decided by juries, a curse and a blessing), or runs out of money. This is analogous to the libel/slander situation in Britain, in which the cost of defending against a libel suite is enough to ruin a journalistic enterprise.
