Note 5. Patents

Patents represent legal fees and filing costs that are capitalized and will be 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. In both 2016 and 2015, we capitalized approximately $0.2 million and $0.1 million, respectively, for patent filing costs. The total investment in patents was approximately $1.2 million and $1.0 million as of December 31, 2016 and 2015, respectively.

 

No amortization expense of patents was recorded in either of the years ended December 31, 2016 and 2015. These patents were not placed in service for the years ended December 31, 2016 and 2015, or in prior years.
