The Company&amp;#39;s patents and trade secrets are for document anti-counterfeiting and anti-scanning technologies and processes that form the basis of the Company&amp;#39;s document security business. Patent application costs are capitalized and amortized over the estimated useful life of the patent, which generally approximates its legal life. The Company accounts for other intangible amortization as an operating expense, unless the underlying asset is directly associated with the production or delivery of a product. Costs incurred to renew or extend the term of recognized intangible assets, including patent annuities and fees, are expensed as incurred. To date, the amount of related amortization expense for other intangible assets directly attributable to revenue recognized is not material.&lt;/p&gt; &lt;p style="FONT: 10pt Times New Roman, Times, Serif;
