Patents are broken in the USA because lawyers makes a ton of money out of it and they contribute a ton of money to political parties that are happy to keep it this way.
I am not familiar with virtnetX case but patent are suppose to protect non trivial innovations yet everybody (including Apple and I am not faulting them because everybody does it) try to patent anything and then unleash their lawyers.
But I am not very sympathetic with Apple or any other Big Tech because at the end of the day they are the ones that benefits the most from this system (beside the lawyers).
Patents were not meant to protect an investor class, it was to protect an active corporation's products from being stolen and used by another corporation in their products. I don't think those that originated the whole patent process thought that a corporation would excel at buying patents from other (bankrupt) corporations, turn patent defense into their 'product', and use well paid lawyers to defend them, even if they themselves know they are crap patents.
Some of the patents I've read sound like they were written by a three year-old. They are so vague, and vast that they could almost be stretched to encompass damn near anything. And THAT should be illegal.
Here's an example of a patent troll in action. Imagine, coming up with a patent that could be stretched to include people checking the status of their packages sent through USPS. You are sued for allowing people to see where their package is, even though you settled that dispute with USPS directly! Imagine the gall, and balls to assert that just because you allowed the USPS website to search for shipping information without demanding a monetary judgement, you are suing everyone else using their own server side scripts to essentially do the same damned thing! Yeah, but often very ignorant courts, and equally ignorant jurists are trusted to rule in cases such as these. Some jurisdictions also make a killing off of the 'gifts' of litigants in cases where they know darn well they have a snowballs chance in hell of winning in any other jurisdiction.
Organizations that troll patents are a very huge concern for companies in this country. Did you hear of the troll that sued auto manufacturers for the delay feature in windshield wipers? Its epic. They tried to sue everyone they could, and made a mint doing it. Something so obvious, something so easy to due multiple ways, and yet nearly everyone that did 'it' (time delayed wiper action) was subject, and threatened by that parasite. I read that some companies settled, payed the ransom, to continue doing what they were doing. A simple feedback loop with a capacitor, that triggered the wiper motor to cycle. Yikes...
