You must be careful about doing research into patents yourself (as a founder or engineer). If it can be proven that you had prior knowledge of a patent, then you may be liable for treble damages.

Patent trolls "win" by extracting money from companies producing/doing actual things; see the recent Newegg case and many others. If you are thinking about creating a company or innovative product, and also decide to launch said company/product outside of the U.S., then you effectively deny them battle. You cannot lose a battle that you do not fight.

I believe that patent trolls "win" when everyone is too scared to stand up for what they believe in. Plain and simple, if people don't take a stand, then things won't change. And I don't necessarily mean just taking a stand in court, I'm talking more about how we (as developers and innovators) react to the issue. I agree that leaving the US will probably lower your chances of becoming a patent troll victim, but everything is relative. Maybe you're building something truly novel and innovative and you want to protect it? Would this outweigh the risk of becoming a patent troll victim? I guess it depends on what (and where) you're building.

How about a foreign corp that owns the IP (which a patent troll may at some point arbitrarily claim was infringing) licensing that IP to a US-based corp. Is the US-based corp exposed to any liability? Probably? Maybe?
For Americans, the Dutch-American Friendship Treaty[0] might be just what you're looking for.
As one patent troll told me on reddit, there's just too much gold to mine and low hanging fruit in the US to bother with anyone else.
Mojang is bigger than many small companies, but is still quite small.
I wonder whether they'd have actually been successful had they not withdrawn. It seems a bit strained that they claim they're doing business in Texas.

What in the world is going on with the US patent system that things like this are emitted.
