Revenue from international sources approximated $915 and $858 for the years ended December 31, 2013 and 2012, respectively. As part of our revenue from international sources, we recognized approximately $894 in product revenue from a number of German companies, in the aggregate, for the year ended December 31, 2013. Revenue from these same international sources approximated $548 for the year ended December 31, 2012. 2012 also included revenue from the previously described Japanese licensee of $279. That license expired with no related revenue recognized during 2013.
