In 2019, the Company continued to reassess 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. As a result, during the year ended December 31, 2019, the Company recorded impairment loss of $733,000 of capitalized patents costs and $322,000 during the year ended December 31, 2018.
