Acquired in-process research and development (“IPR&D”) is an intangible asset accounted for as an indefinite-lived asset until the completion or abandonment of the associated research and development effort. If the research and development effort associated with the IPR&D is successfully completed, then the IPR&D intangible asset will be amortized over its estimated useful life to be determined at the date the effort is completed. The development effort on the IPR&D intangible asset is expected to be completed by the first half of fiscal year 2016.


⁽²⁾	During the three months ended January 31, 2015, the Company purchased a perpetual, non-exclusive license to certain patents for $7.8 million.

The patent license was assigned an estimated useful life that reflects the Company’s consumption of the expected defensive benefits related to this intangible asset. The method of amortization for the patent license reflects the Company’s estimate of the pattern in which these expected defensive benefits will be consumed or otherwise used up by the Company, and is primarily driven by a mix of expiration patterns of the individual patents included in the license.
