Though, could a patent troll could get around that by spacing out the trolling? So by the time any company finds another company that's been trolled, they've already paid it up and don't have as much incentive to fight the patent troll after the fact.
They could even offer a "discount" conditional upon mandatory non-disclosure of the legal threat.
That's still a minor win, since it mitigates the amount of damage the trolls can do per unit time.
The site does look like it's being maintained. The most recent case I found was from June 2017:

Also noticed in the "About" section that Trolling Effects is a project of the Electronic Frontier Foundation. Which is another great reason to support the EFF.
Of course, the tricky part is not preventing legitimate patent litigation, but if you word it carefully enough, it could make it risky enough for patent trolls to not be worth it. The tradeoffs change when it's not LLC money at risk but the participant's personal freedom, so even if only 10% of patent trolls could be actually convicted, it might be enough to discourage the rest.
Or, of course, just dump software patents alltogether...
It's just taking the money you'd be forced to pay some exploitative patent troll, and giving it (well, probably/hopefully less of it, but still) to an exploitative insurance firm instead.
Locksmiths and firefighters aren't exploitative.
This is why people in high risk categories pay more for insurance (eg young people and people with high performance cars have higher car insurance premiums because statistically they crash more often and/or have higher rates of total loss)
All this time I thought they invested the float.
What'd be most disheartening is if the insurance was just to pay off the patent trolls
First, you won't be able to get insurance for this case, because it predates your policy. A bit like getting fire insurance when your house is already on fire.
Second, an insurance company won't just write you a blank cheque for legal fees, they will take over the case and look for the cheapest way out, which will probably be settlement.
Hence, specific insurance against patent trolls could work by effectively taking away the easy targets for patent trolls. It's a bit like home-insurance companies that offer discounts on good locks to keep out thieves. Everyone except for the criminals are better off afterwards.
I don't know if the second point is a big deal. Even if they choose to settle, you've still mitigated your risk without going to court. And I suspect a patent litigation insurance agency is going to be motivated to negotiate very small settlements and/or actually fight it out in court, lest they gain a reputation as the company that hands out license fees.
I'm curious if someone familiar with the matter happens to be reading - is there any provision in the system for Playsaurus to now have the case taken the court regardless of the fact GTX did not infact file a lawsuit, i.e. attempt to have it invalidated even if GTX drop the threat of the lawsuit? Or would they need to piggy back / support one of the other companies listed in this blog?
