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, 2024 and 2023.

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)		2024			2023
Capitalized patent costs	~17		$	9,116		$	9,231
Intangible assets acquired:
Purchased intellectual property		10		250			250
Developed technology		5		22,638			22,836
Customer relationships		10		10,818			10,913
Gross intangible assets				42,822			43,230
Accumulated amortization				(16,102	)		(14,772	)
Intangibles, net			$	26,720		$	28,458

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.
