A dispute exists surrounding the
trademark and
intellectual property rights to Feiyue between the United States-owned company, Feiyue International, LLC, and Shanghai Da Fu Rubber Co, the company that originally manufactured the shoe. Liu Qinglong, manager of Shanghai Da Fu Rubber Co Ltd, said of the situation in 2017, “No one in China knew about commodity intellectual property rights at the time and it wasn’t until 2007–08 that we found out the French had registered the trademark.” According to the Young Post: "Liu claims the French company took advantage of the Chinese at a time when China was still grappling with capitalism and transitioning from all factories being state-owned assets to devolving some rights to individual businesses." However, Da Fu maintains that Bastien made this purchase from a manufacturer and not from them, the original company, having not heard of the Bastian at all until 2007. Da Fu took Feiyue International, LLC to court for the rights in France, but lost the lawsuit. == Distinctions between the original authentic Chinese and re-designed American versions ==
