A professor in St. Louis who says he helped come up with the idea that became payments-company Square has filed a lawsuit against the company, alleging fraud and patent infringement and seeking unspecified damages. Robert E. Morley, a professor at Washington University in St. Louis, filed suit in federal court in St. Louis on Thursday against Square and its co-founders Jack Dorsey and James McKelvey. “The business now known as Square was not created solely by Jack Dorsey and James McKelvey,” said the complaint. “It was Professor Robert Morley – and Dr. Morley alone – who invented the Square card reader, and Dr. Morley co-invented the corresponding magnetic stripe,” the complaint continued.
