Income Tax Disclosure [Text Block] | NOTE 5 – INCOME TAXES As of September 30, 2024, the Company had net operating loss (“NOL”) carryforwards of approximately $353 million for federal income tax purposes and $328 million for California state income tax purposes. Such carryforwards expire in varying amounts through the year 2037 and 2043 for federal and California purposes, respectively. For federal losses arising in tax years ending after December 31, 2017, the NOL carryforwards are allowed indefinitely. Use of the carryforward amounts is subject to an annual limitation as a result of a previous ownership change and an ownership change that occurred in June 2021. As of September 30, 2024, the Company’s unrecognized tax benefits were immaterial. The Company's tax years 2021 through 2023 remain subject to examination by the Internal Revenue Service, and tax years 2020 through 2023 remain subject to examination by California tax jurisdictions. In addition, the Company's loss carryforward amounts are generally subject to examination and adjustment for a period of three years for federal tax purposes and four years for California purposes, beginning when such carryovers are utilized to reduce taxes in a future tax year. Because it is more likely than not that the Company will not realize its net deferred tax assets, it has recorded a full valuation allowance against all deferred assets. Accordingly, no deferred tax asset has been reflected in the accompanying condensed consolidated balance sheet.
