Note 6. Patents and Other Assets Patents represent legal fees and filing costs that are capitalized and amortized over their estimated useful lives of 17 to 20 years or their remaining legal lives, whichever is shorter, after they are placed in service. There were no patents placed in service for the years ended December 31, 2011 and 2010. In 2011 we capitalized approximately $0.2 million for patent filing costs, for a total investment in patents of approximately $0.6 million as of December 31, 2011. In 2010 we capitalized approximately $0.1 million for patent filing costs, for a total investment in patents of approximately $0.4 million at December 31, 2010. No amortization expense of patents was recorded in either of the years ended December 31, 2011 and 2010. These patents were not placed in service for the years ended December 31, 2011 and 2010, or in prior years. Security deposits at December 31, 2011 and 2010 of $0.1 million represent the security deposit placed on the Tysons Corner, Virginia corporate offices. |
