The Company capitalizes legal costs and filing fees associated with obtaining patents on its new discoveries. Once the patents have been issued, the Company amortizes these costs over the shorter of the legal life of the patent or its estimated economic life using the straight-line method. Based upon the current status of the above intangible assets, the aggregate amortization expense is estimated to be approximately $81,000 for each of the next five fiscal years. The Company tests intangible assets with finite lives for impairment upon significant changes in the Company's business environment. The testing resulted in net patent impairment charges of $32,000 and $200,000 for the three and nine month periods, respectively, ended September 30, 2016 and no patent impairment charges for the three month period ended September 30, 2015 and $5,000 in patent impairment charges for the nine month period ended September 30, 2015.  The impairment charges are related to the Company's ongoing analysis of which specific country patents in its portfolio are determined as potentially worth pursuing.
