	September 30, 2012						December 31, 2011
(In thousands)	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
Developed technology	$	7,775	$	(7,775)	$	—	$	7,775	$	(7,775)	$	—
Patents		2,829		(2,621)		208		2,734		(2,504)		230
	$	10,604	$	(10,396)	$	208	$	10,509	$	(10,279)	$	230

Amortization expense for the three and nine month periods ended September 30, 2012 and 2011 is as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(In thousands)	2012		2011		2012		2011

	$	39	$	65	$	117	$	265

Intangible and other long lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.  An impairment loss would be recognized when future undiscounted cash flows expected to result from use of the asset and eventual disposition are less than the carrying amount.

Amortization of patents and trademarks has been classified as research and development expense in the accompanying statement of operations.  Estimated aggregate amortization expense based on current intangibles for the next four years is expected to be as follows: $37,000 for the remainder of 2012, $106,000 in 2013, $52,000 in 2014, and $13,000 in 2015.
