Note 3.  Other long-term assets:

  $ 1,287,215     $ 1,214,797  


    387,239       387,239  


     $ 1,674,454      $ 1,612,160  


Amortization expense totaled approximately $21,000 and $41,000, and $22,000 and $41,000 for three and six month periods ended June 30, 2014 and 2013, respectively.


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 upon significant changes in the Company's business environment. The testing resulted in no patent impairment charges in 2014, and approximately $3,000 of total impairment charges during the three and six month periods ended June 30, 2013.
