Elkins Park, Penn.-based NOAH Bank has sued Duluth, Ga.-based NOA Bank alleging trademark infringement, false designation of origin and description and unfair competition. NOAH Bank representatives said the suit stems from NOA Bank’s recent hiring of a former NOAH officer and the opening by NOA Bank of a loan production office in New York in March 2016. NOAH alleges NOA has intentionally engaged in a scheme to confuse customers and prospects of NOAH in an effort to steal business. In particular, NOAH claims NOA targeted the Korean-American community it serves by adopting infringing trademarks and using NOAH’s confidential and trade secret information, which it got from NOAH’s former executive vice president and senior lender.
