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.
