The value of intangible assets includes the cost of acquiring patent rights, supporting data, and the expense associated with filing approximately 11 patents and 35 trademarks. It also includes acquisition costs related to brands and domains.

The amortization of patent and patent rights with finite life is up to 20 years, commencing from the date of grant. The amortization expense in the three months ended September 30, 2020 and 2019, amounted to approximately $3 thousand and $4 thousand, respectively, whereas the amortization expense in the six months ended September 30, 2020 and 2019, amounted to approximately $6 thousand and $4 thousand, respectively.

The Company regularly reviews its intangible assets to determine if any intangible asset is other-than-temporarily impaired, which would require the Company to record an impairment charge in the period and concluded that, as of September 30, 2020, there was no impairment.
