Intangible Assets Disclosure [Text Block] | Note 6 - Intangible Assets and Goodwill In connection with our previous acquisitions, we have recorded identifiable intangible assets related to existing technology, customer relationships, trade names, and trademarks, based on guidance for determining fair value under the provisions of ASC 820, "Fair Value Measurements." We are amortizing the intangible assets using the straight-line method over their estimated useful lives. Additionally, we have entered into license agreements for third-party technology and recorded them as intangible assets. These licenses are being amortized to Research and development expense over their estimated useful lives. No impairment charges relating to acquired intangible assets were recorded for fiscal 2023, 2022, or 2021.
