Developed technology is amortized on a straight line basis over 10 to 20 years, depending on the life of the product technology. Intangible assets related to customer relationships are generally amortized over a period of up to 10 years on an accelerated basis. In-process research and development is amortized on a straight line basis over the product’s estimated useful life upon completion of the technology. Other intangible assets include acquired backlog, product trademarks and trade names, non-competition agreements and defensible assets. With the exception of product trademarks and trade names, such assets are amortized on a straight line basis over a period of three months to 10 years, depending on the asset. Trademarks and trade names associated with products are amortized on a straight line basis over the estimated remaining life of the product technology, which ranges from 10 to 20 years. Trademarks and trade names associated with a business have indefinite lives and are not amortized.

Amortization expense related to intangible assets totaled $2.6 million and $7.7 million for the three and nine months ended September 28, 2013, respectively, and $4.6 million and $14.8 million for the three and nine months ended September 29, 2012, respectively.

Estimated aggregate amortization expense for future fiscal years is as follows:

(In thousands)	Estimated Aggregate Amortization Expense
2013 (remaining)	$	2,598
2014	8,404
2015	6,770
2016	6,386
2017	5,406
Thereafter	19,998
	$	49,562

The Company has excluded $2.0 million of amortization expense related to certain in-process research and development from the table above, as it was uncertain as of September 28, 2013 when the technology will be completed and when the amortization will begin.
