Lawsuit In October 2014, after years of sending unsuccessful cease and desist letters, Converse filed a lawsuit against 31 companies for allegedly infringing on its sneaker style's bumper toe, striped midsole, and toe cap.

The restyled Converse All Star basketball shoe also had a distinctive five-pointed-star logo displayed on the high-top shoe's ankle patch. In addition, Taylor's signature was incorporated into the high-top's ankle patch, resulting in the design that became known as the Chuck Taylor All Star.
