There are so many problems with the patent system, it's hard to identify a primary problem. I'd say the worst thing about it is that it is simply non-functional for any individual or small business. Got a patent? Someone infringing? Sue them! Cost? Astronomical. Selling something? Patent Trolls trying to make a grab? Defend yourself in court! Cost? Astronomical. Those scenarios merely address outright abuse; but, the way patents are granted guarantees that those situations will also arise between parties who aren't trolls.
