Intangible Assets Disclosure [Text Block] |
12. Intangibles
Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. No impairment charges were recorded for the three months ended March 31, 2023 and 2022.
Patent costs associated with the application and award of patents in the U.S. and various other countries are capitalized and amortized on a straight-line basis over the term of the patents as determined at the award date, which varies depending on the pendency period of the application, but generally approximates seventeen years.
Amortization of intangible assets acquired is calculated using the straight-line method over the estimated useful lives of the assets.
The amortization of capitalized patent costs, purchased intellectual property, and developed technology is recorded in “cost of revenue” and the amortization of customer relationships is recorded in “operating expenses” in the Consolidated Statements of Operations.
Amortization expense on intangible assets was as follows:
For intangible assets recorded at March 31, 2023, the estimated future aggregate amortization expense for the years ending December 31, 2023 through December 31, 2027 is as follows:
