Chinese companies don't respect patents from western companies, so why should western companies respect Chinese companies patents it's only fair right, they probably ripped it off an existing design concept anyway.
Looks like they've gone extremely short focal length on the wide angle side so the 10x zoom is not actually so impressive at 160mm full frame equivalent, but still handy. I can't begin to imagine what the distortion is like, however I guess the current paradigm is to embrace distortion and correct in software rather than adding corrective optics.
