A Florida company has filed a lawsuit against Bank of America Corp., saying the bank’s “Keep the Change” savings program infringes on a patent.

Every Penny Counts Inc. alleges that Bank of America infringed on a patent in obtained in 2000. The company said it talked with the bank in 2004 and 2005 about licensing its “rounder patent,” but Charlotte-based Bank of America launched Keep the Change on its own.
