In 2014, Segway convinced the US International Trade Commission to investigate infringements of Segway's patents for its self-balancing technology. One of the companies listed in Segway's complaint was Ninebot, which quickly offered to buy the company.

Ninebot saw a company that shared its vision of improving urban transport. It also saw a company with tremendous brand recognition. And it knew it would need Segway's patents to enter the US market. The two sides quickly closed the deal, which was announced April 15, 2015.
