GNUstep being more or less a re-implementation of Cocoa (and prior to that OpenStep). I'm not suggesting any copyrights have been infringed upon (indeed, I'm an avid user of GNUstep), but I always wondered if GNUstep would fall foul of the same kind of patent threats that Mono detractors seem to feel it is at risk from if it ever gained commercial traction. In fact, Apple has already made legal threats against manufacturers of Android phones, Android having nothing to do with Cocoa or Cocoa Touch.
