In Thousands	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Patents		24,715		24,533		24,715		24,410

Amortization expense was $2.8 million and $2.5 million for 2024 and 2023, respectively. At December 31, 2024, the net carrying amount of trade names includes $7.8 million related to indefinite-lived intangible assets which are not amortized but are evaluated for impairment at least annually.

Estimated future amortization expense is summarized in the following table:

All Amounts in Thousands
2025	$	2,265
2026		2,218
2027		2,132
2028		1,482
2029		1,374
Thereafter		8,583
Subtotal		18,054
Indefinite-lived intangible asset balance		7,784
Total	$	25,838

Consistent with our operating segment conclusion, we have concluded one reporting unit exists and all goodwill and indefinite lived intangibles are allocated to that reporting unit. There were no changes to the carrying amount of goodwill in 2024 or 2023.
