(In thousands)		December 31, 2013						December 31, 2012
		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Capitalized software development costs	$	48,947	$	(25,706)	$	23,241	$	45,064	$	(23,450)	$	21,614
Acquired technology		89,446		(54,253)		35,193		89,876		(42,562)		47,314
Patents		26,070		(11,045)		15,025		24,046		(9,398)		14,648

Software development costs capitalized during 2013, 2012, and 2011 were $15.6 million, $12.2 million, and $12.6 million, respectively, and related amortization expense was $14.0 million,  $14.1 million, and $13.4 million, respectively. Capitalized software development costs for the years ended December 31, 2013, 2012, and 2011 included costs related to stock based compensation of $742,000,  $519,000 and $539,000, respectively. The related amounts in the table above are net of fully amortized assets.

Amortization of capitalized software development costs is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three years. Acquired technology and other intangible assets are amortized over their useful lives, which range from three to eight years. Patents are amortized using the straight-line method over their estimated period of benefit, generally 10 to 17 years. Total intangible assets amortization expenses were $32 million, $28 million, and $25 million for the years ended December 31, 2013, 2012, and 2011, respectively.

Capitalized software development costs, acquired technology, patents and other had weighted-average useful lives of 1.8 years, 2.1 years, 4.0 years, and 2.3 years, respectively, as of December 31, 2013. The estimated future amortization expense related to intangible assets as of December 31, 2013 was as follows:

		Amount
		(In thousands)
2014	$	32,972
2015		23,050
2016		12,580
2017		5,521
2018		785
Thereafter		7,402
	$	82,310

The overall increase in our acquired technology and other intangible assets can be attributed to our acquisitions in 2012. See Note 17 – Acquisitions of Notes to Consolidated Financial Statements for additional discussion related to these acquisitions.
