ST. LOUIS (AP) — A Washington University electrical engineering professor is suing credit card processor Square Inc. in the latest legal dispute over the company's mobile plug-in technology.
Robert E. Morley Jr. sued Square and company founders Jack Dorsey and James McKelvey Jr. Thursday in the U.S. District Court for the Eastern District of Missouri. The patent infringement suit calls the Square origin story a "fabrication" and says the two men squeezed Morley out of the San Francisco-based company.
Dorsey, a St. Louis native, is chairman at Twitter, the company he co-founded before becoming Square's CEO. McKelvey is a Washington University graduate who still lives in the St. Louis area and whose father was dean of engineering at the university.
Square and its co-founders sued Morley in 2010 in a related patent dispute that's still pending. A company spokesman said Square plans to aggressively challenge the professor's claims.
"It's not surprising that Morley would file another desperate, baseless patent lawsuit given how poorly his initial claims have been received by the patent authorities," said Square spokesman Aaron Zamost. "We will fight it vigorously."
