So Lian-li fans have pins and pads on the actual fan casing and the fans slide togheter making contact, Phanteks solution involves only pads in a completely different location on the fan casing and the fans are actually linked by an external clip that both makes the electrical contacts by carrying the pins and possibly cables or a PCB inside of them, and also keeps them together in a flimsy manner, but Phanteks is infringing on Lian-li's patent?
If that's true, that means Lian-li has patented daisy-chainable fans in any way shape or form, which would be sad...
