European application developers are withdrawing their apps from US app stores from the fear of getting sued by a patent troll like Lodsys.

The failings of the US Patent laws have led several companies to not only attack established companies like Google and Apple but individual developers in the hopes of opening up new revenue lines from licenses.

According to a report on The Guardian, European application developers believe that it is no longer safe to operate in the US due to the legal threat posed by such companies.

UK based developer Simmon Maddox has removed his apps from the App Store and the Android Market from the fear of receiving a legal notice by Lodsys. Lodsys has served legal notices to several Android and iOS developers for allegedly violating its patents.

Some developers, like Shaun Austin, believe that selling software in the United States had reached its tipping and many are questioning their future as app developers.

Developers believe that they are not protected from litigation even if they develop for bigshots like Apple, Microsoft and Google as none of these companies have come forward to defend those who develop for them.
