Goodwill and Intangible Assets Disclosure [Text Block] | Note 11. Goodwill and Intangibles The Company tests Goodwill for impairment annually at fiscal year-end, or more frequently when events or changes in circumstances indicate that the asset might be impaired. The Company assesses qualitative factors to determine whether the existence of events or circumstances would indicate that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The result of the analysis performed as of September 30, 2023, did not indicate an impairment of goodwill. During the three months ended December 31, 2023, there were no triggering events that indicate potential impairment exists. The Company capitalizes legal costs incurred to obtain patents. Once accepted by either the U.S. Patent Office or the equivalent office of a foreign country, these legal costs are amortized using the straight-line method over the remaining estimated lives, not exceeding 20 years. As of December 31, 2023, the Company has 48 patents granted and multiple pending applications both inside and outside the United States. In addition, the Company has various finite lived intangible assets, most of which were acquired as a result of the acquisition of the active cabinet product line from Calix, Inc. during fiscal year 2018 and the acquisition of Nestor Cables in fiscal 2022. The Company analyzes its intangible assets for impairment annually or at interim periods when events occur or changes in circumstances indicate potential impairment. The result of the analysis performed as of September 30, 2023, did not indicate an impairment of our intangible assets. During the three months ended December 31, 2023, there were no triggering events that indicate potential impairment exists.
