Intangible Assets Intangible assets consist entirely of patent costs that provide the Company with rights, titles, and interests in the development of certain processes, discoveries, and inventions with the right to commercialize that are probable of future economic benefits. Patent costs associated with pharmaceutical intellectual property are expensed as incurred as future economic benefits are not deemed to be probable. Intangible assets are recorded at cost and are amortized over the estimated life of the patents, based on the approval and expiration dates applicable to each patent — typically 20 years — on a straight-line basis. Amortization expense related to intellectual property for 2022 and 2021 was $122 and $103, respectively. We did not record any impairment losses in 2022 or 2021.
