Now, I really believe that unless things change, the US is going to have a lot of trouble attracting new businesses to start at home, or foreign companies providing services in the US. Spotify will run their own cost benefit analysis of fighting the lawsuit versus attracting future revenue. Many small services that cannot afford an upfront lawsuit in the hope of future American revenue will just not open shop or services for the US.
It hurts me to see how the patent system is screwing with every damn thing. As they say for startups, competition from other countries won't hurt America, but inefficiencies and bad decisions within would. And IMHO the risk is not hypothetical anymore.
