First of all, Porsche should apply for a patent for automobile appearance in China and obtain a patent certificate before suing the infringer. Unfortunately, Porsche did not apply for the appearance patent of its products in China, nor did it hear that other foreign automobile manufacturers applied for the appearance patent of their products in China. Secondly, Zotye applied for an appearance patent for its products. Therefore, Porsche has no way to sue Zotye for infringement. On the contrary, Zotye may sue Porsche for infringement. Zotye will certainly not sue Porsche, and the two families will continue to live in peace.
