Other Income Disclosure, Nonoperating | 11. Other income, net: In 2002, various patents which were acquired by us in the merger with Infonautics in 2001 were assigned to an unrelated third party. In connection with the assignment of these patents, we retained the right to a share of any cash flow received by the unrelated third party relating to the commercialization of these patents. As a result of this assignment, during the year ended December 31, 2011 we received an amount of $0.4 million. No amount was received during the years ended December 31, 2012 and 2010. In March 2012, we received an amount of $0.5 million on the sale of certain intangible assets with no book value.
