As much as patent trolls are an enormous problem, they are not the only villains in this story. The others are of course the lawyers and the courts.
Let's say that you received a summons in the mail informing you that your startup was being sued. First of all, why are you receiving it in the mail? Why can't the Secretary of State ask for your e-mail address (as some do) and actually use it for service of process? (Answer: because the courts aren't even sure they want to allow a technology as sophisticated as Certified Mail to be permitted for service of process, let alone fax. E-mail? You must be joking.)
Once you get the summons, assuming you can even understand what it means, what do you do? Look up the case on-line? Probably not. That would require you to have a PACER account, which costs money beyond $15.00 per quarter in fake-page access at $0.10 per fake-page. It would also require you to know how to navigate the system, which isn't particularly easy. Assuming that you could, and could understand the legal documents, you might be able to learn a lot right there.
Instead, what most people would do is pay a lawyer to handle all of this for them, at anywhere from $300 to $600 per hour. But what does lawyering really involve? Copying and pasting from Microsoft Word templates, turning Word files into PDFs, attesting to obvious things ("I have caused this envelope to be placed in the mail as of this date") and occasionally reading a similar case to cite. But mostly it's not that difficult. There are definitely aspects that require skill and logical thinking. That's maybe 5% of the work.
So why are we paying $300 to $600 per hour for highly indebted people to do things that computers could? Because the courts won't let computers into the picture. They won't even let companies represent themselves through their founders, even though Citizens United guarantees corporate freedom of speech (everywhere except inside the courtroom, apparently). If they did allow technology to enter the picture, handling a patent infringement assertion might actually be fairly trivial--something you could do in a few minutes on a web form--and at worst, as annoying as calling customer service.
The USPTO isn't blameless either. For more on that you can look at some slides from a presentation I gave at the USPTO Software Patent Round Table in February, 2013.
