Several major banks were hit on Monday with lawsuits filed by California-based analog circuits maker Maxim Integrated Products Inc alleging their smartphone banking apps infringe the company's patents. The complaints were filed against M&T Bank Corp and the U.S. affiliates of HSBC Holdings Plc and Banco Santander SA in federal court in Manhattan, alleging the banks' apps, when downloaded to Android devices and Apple Inc products such as the iPhone, use the patents without permission.
