Mobile credit card payment startup Square, whose card reading service works with a nifty magnetic card reader that plus into a mobile device’s headphone jack, is missing a very important piece: The patent for the hardware.
Square, Inc. and founder Jim McKelvey filed a complaint against Robert Morley, Jr., an associate professor of electrical engineering at Washington University, claiming that he neglected to list McKelvey as co-inventor of the device.
According to the story told McKelvey, a glass artist and entrepreneur, he came up with the idea for a mobile card reader in 2009 after losing a sale because he couldn’t accept credit card payments. He then teamed up with friend and Twitter co-founder Jack Dorsey, and they decided to use a mobile phone’s headphone jack as a way of interfacing with a card reading device. McKelvey then turned to friend Morley to help design the prototype hardware.
The three reportedly had discussed obtaining a patent once the prototype was finished, but Morley filed solo in June 2009, and a patent in his name for the card reader device was granted on October 12, 2010. Read more
