11. 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, 2025 and 2024.

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.

	Estimated Life		March 31,			December 31,
	(years)		2025			2024
Capitalized patent costs		~17	$	9,160		$	9,174
Intangible assets acquired:
Purchased intellectual property		10		250			250
Developed technology		5		23,180			22,504
Customer relationships		10		11,077			10,754
Gross intangible assets				43,667			42,682
Accumulated amortization				(22,505	)		(20,491	)
Intangibles, net			$	21,162		$	22,191

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 and Comprehensive Loss.

Amortization expense on intangible assets was as follows:
