During 2017, our litigation with Biosig Instruments, Inc. ("Biosig") was settled. The litigation began in 2004 and alleged patent infringement in connection with our incorporation of heart rate monitors into certain cardio products of our former Commercial business. We paid Biosig $1.2 million under the settlement, and the matter was dismissed with prejudice. The settlement was expensed in discontinued operations in 2017.
