App developers withdrawing from US app stores because of patent troll fears

Our messed up patent system is reaching a tipping point, where we are seeing developers avoid the US market and its patent trolls:

The growth of patent lawsuits over apps raises serious issues for all the emerging smartphone platforms, because none of the principal companies involved – Apple, Google or Microsoft – can guarantee to protect developers from them. Even when the mobile OS developer has signed a patent licence – as Apple has with at least one company currently pursuing patent lawsuits – it is not clear that it has any legal standing to defend developers.

Craig Hockenberry of Iconfactory, developer of Twitterrific, remarked that “Just when you think things couldn’t get any worse, they do and tweeted that “I became an independent developer to control my own destiny. I no longer do”. Iconfactory is among those being targeted by Lodsys, but earlier this week was granted a 30-day extension to reply to Lodsys’s claim.

What do patents protect? They protect us from excess innovation it seems.
