Recently active topics in EFF about Patent Busting Project

I see that the EFF has a "Patent Busting" program, but it's all overwhelming to me.

Can somebody explain in a few simple bullet points what's wrong with the current US patent system, and why technology companies should or shouldn't invest the time, money, and resources into filing for them?

Something I could use in an argument with the co-founders of my current startup company would be ideal -- I really don't want to put the time and effort into patents if there's no value in doing so.
