	December 29, 2012
(In Millions)	Gross Assets		Accumulated Amortization			Net
Acquisition-related developed technology	$	2,778	$	(1,116	)	$	1,662
Acquisition-related customer relationships	1,712		(551		)	1,161
Acquisition-related trade names	68		(33		)	35
Licensed technology and patents	2,986		(699		)	2,287

Identified intangible assets not subject to amortization	938		—			938
Total identified intangible assets	$	8,720	$	(2,485	)	$	6,235

For identified intangible assets that are subject to amortization, we recorded amortization expense on the consolidated condensed statements of income as follows: amortization of acquisition-related developed technology and licensed technology and patents is included in cost of sales, amortization of acquisition-related customer relationships and trade names is included in amortization of acquisition-related intangibles, and amortization of other intangible assets is recorded as a reduction of revenue.

Amortization expenses during each period were as follows:



	Three Months Ended				Nine Months Ended
(In Millions)	Sep 28, 2013		Sep 29, 2012		Sep 28, 2013		Sep 29, 2012
Acquisition-related developed technology	$	150	$	141	$	430	$	420
Acquisition-related customer relationships	70		71		208		224
Acquisition-related trade names	3		3		8		9
Licensed technology and patents	69		53		204		148
Other intangible assets	—		—		103		—
Total amortization expenses	$	292	$	268	$	953	$	801

Based on the identified intangible assets that are subject to amortization as of September 28, 2013, we expect future amortization expense to be as follows:



(In Millions)	Remainder of 2013		2014		2015		2016		2017
Acquisition-related developed technology	$	151	$	587	$	313	$	221	$	72
Acquisition-related customer relationships	70		268		251		233		141
Acquisition-related trade names	3		10		9		3		—
Licensed technology and patents	66		259		242		227		189
Total future amortization expenses	$	290	$	1,124	$	815	$	684	$	402
