I'd have to agree - I think the patent system is broken too.
It can be used to protect innovation, but if implemented incorrectly it can also lead to patents being granted too readily and 'patent squatting'.
I'd have to disagree on causality. The existence or number of suits has little bearing on the function of a system of laws. It's an easy media attack and a common popular sentiment, but as someone who works with this sort of thing, it's in reality fairly unjustified.
There are millions of current patents. Yes, some of them are silly, some of them are unenforceable, and some of them are just plain invalid. What people fail to realize is that for as much humor and derision as people can make out of it, it wouldn't have come to court if there wasn't merit to it (and this one hasn't even been heard). The media doesn't care about that part, though. They also don't care about the outcome or process. The news reports on filings of suits, but then they disappear once everyone has had their fun. No one ever follows up to say "demurrer granted" or "judgment in favor of defendants." It's not newsworthy when these suits resolve naturally.
The patent system does grant strange patents. How would you (not you personally, necessarily, but people in general) propose minimizing these? You can take more time to review patents and confer with technical experts on the relevant matters, but that will increase processing time in an already backlogged system. You could expand the office, but that would cost money, and nobody wants to pay for it, least of all the people who like to complain about the system. You could reduce the frivolity of patent suits by sending them all directly to closed-door mediation beforehand, but then there would be complaints of back-room wheeling and dealing outside of the public eye.
Striking a balance of efficiency, thoroughness, and openness is quite difficult. We have lawsuits to iron out the "oops" moments. I'm not sure what's broken. You can't stop people from making frivolous claims and filing groundless suits. No matter what you do to the law, people will always be able to file suit for whatever they want and often just for publicity. After all, the media doesn't follow any but the biggest of the suits, so it's only the filing itself that makes a splash. $20,000 in legal fees for a month of a facade, and a million dollars worth of free media coverage. It does wonders for marketing and business.
