Note 3. Finite-Life Intangible Assets

The carrying value of patents and trademarks includes the original cost of obtaining the patents, periodic renewal fees, and other costs associated with maintaining and defending patent and trademark rights. Patents and trademarks are amortized over their estimated useful lives, generally 15 and 12 years, respectively. Accumulated amortization was $511,000 and $479,000 at September 30, 2013 and June 30, 2013, respectively.

The activity and balances of finite-life intangible assets were approximately as follows:
