In 2016, the Company reassessed its patent portfolio in order to ensure that both the cost-effectiveness and the value created through the intellectual property portfolio were maximized and to focus resources on its most promising patents. Those patents considered to be the most beneficial were retained and those pending patents projected to be unnecessarily costly that could be disposed of without meaningfully degrading the quality of the remaining intellectual property portfolio were abandoned. Further, an impairment loss was recorded for certain other patents pending which are believed to be of diminished value, but in the judgment of management remain worthwhile to continue to pursue until the product attributes and related reasonable patent protection can be better determined. As a result, during the years ended December 31, 2016 and 2015, the Company recorded impairment losses of $1,971,000 and $593,000 respectively, of capitalized patents pending. A reconciliation of patent activity for the years ended December 31, 2016 and 2015 is summarized as follows:
|  | Duplex |  | ECC |  | Total |
Balance at January 1, 2015 |  | $ | 481,000 |  | $ | 1,848,000 |  | $ | 2,329,000 |
