| Significant Accounting Policies [Text Block] |
Note 2 — Summary of Significant Accounting Policies
Basis of Presentation
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Accounts Receivable
Trade accounts receivable are stated net of a provision for credit losses. The provision for credit losses represents an estimate of the lifetime expected credit losses inherent in trade receivables as of the balance sheet date. The Company assesses the adequacy of the provision for credit losses on a quarterly basis based on historical information and current economic conditions and forecasts. Subsequent changes in the provision for credit losses are recorded in current earnings and reversal of previous losses are permitted under the current guidance. While the Company believes it has exercised prudent judgment and applied reasonable assumptions, there can be no assurance that in the future, changes in economic conditions or other factors will not cause changes in the financial health of its customers. If the financial health of customers deteriorates, the timing and level of payments received could be impacted and therefore, could result in a change to the Company’s estimated losses.
Trade accounts receivable at December 31, 2024 relate to product sales. At December 31, 2024, the provision for credit losses was $0.
Property and Equipment
Property and equipment are stated at historical cost less accumulated depreciation and amortization. Major additions and improvements are capitalized while maintenance and repairs that do not improve or extend the useful life of the respective asset are expensed. Depreciation and amortization of property and equipment is computed using the straight-line method over their estimated useful lives. Leasehold improvements are amortized over the shorter of the life of the asset or the related leases. Estimated useful lives of the principal classes of assets are as follows:
Intangible Assets
The Company’s intangible assets are composed of patents and trademarks, which are recorded at cost, and other intangible assets, which are recorded at cost plus the estimated present value of all future payments associated with the other intangible assets. The Company capitalizes third-party legal costs and filing fees, if any, associated with obtaining patents, trademarks or other intangible assets. Once the patent asset has been placed in service, the Company amortizes these costs over the shorter of the asset’s legal life, generally 20 years from the initial filing date, or its estimated economic life using the straight-line method. Trademarks are not amortized as trademarks have an indefinite useful life. For the other intangible assets, the Company amortizes the assets over the 11-year and 17‑year terms of the underlying agreements.
Impairment of Long-Lived Assets
The long-lived assets, consisting of property and equipment and intangible assets, held and used by the Company are reviewed for impairment no less frequently than annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the event that facts and circumstances indicate that the cost of any long-lived assets may be impaired, an evaluation of recoverability is performed. Management has determined that there was an impairment in the value of long-lived assets in the amount of $77,444 during the year ended December 31, 2024. There were no impairments in the value of long-lived assets during the year ended December 31, 2023.
Fair Value
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs used to establish fair value are the following:
The Company’s financial instruments primarily consist of cash and cash equivalents, accounts payable and long-term liabilities. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short-term nature of these instruments.
In 2015, the Company recorded a long-term liability for the estimated present value of future payments under licensing agreements. In 2021, the Company recorded an adjustment to increase the long-term liability due to an increase in the future payments due under these licensing agreements. In 2023, the Company recorded a long-term liability for the estimated present value of future payments under a separate licensing agreement. The Company determined the discount rate to estimate the present value of the future payments based on the applicable treasury rates. The Company’s long-term liability is classified within Level 3. See Note 5 and Note 8 for more details regarding the licensing agreements. The Company did not identify any other assets and liabilities that are required to be presented in the balance sheets at fair value.
Revenue Recognition
The Company recognizes revenue and related cost of revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers” and, as applicable, with the guidance issued by the FASB in June 2018 for the recipients of grants.
Commercial revenue relates to either the development agreements with customers or product sales. Commercial revenue under development agreements is generally recognized upon the completion of contractual deliverables. Commercial revenue from product sales is generally recognized upon shipment of products. Grant revenue relates to government contracts. Government contracts are agreements that generally provide the Company with cost reimbursement for certain types of development activities over a contractually defined period. Grant revenue is recognized in the period during which the Company incurs the related costs, provided that the Company has incurred the cost in accordance with the specifications and work plans determined between the Company and the government entity.
For the year ended December 31, 2024, the Company recognized $86,032 in commercial revenue and no grant revenue. For the year ended December 31, 2023, the Company recognized $161,483 of commercial revenue and $37,388 of grant revenue.
Research and Development
Research and development costs are presented as a line item under operating expenses and are expensed as incurred. Research and development costs include costs to further develop the Company’s B-TRAN® technology and related products and include, but are not limited to, the cost of engineering personnel, wafer fabrication, contract labor, driver design and fabrication, device packaging, product development, testing and other engineering services, stock-based compensation for engineering personnel, consulting and materials and supplies.
Income Taxes
The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. At December 31, 2024 and 2023, the Company established a full reserve against all the net deferred tax assets.
Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.
Net Loss Per Share
The Company applies FASB ASC 260, “Earnings per Share.” Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include additional common shares available upon exercise of equity awards and warrants using the treasury stock method. In periods with a net loss, no common share equivalents are included because their effect would be anti-dilutive.
In accordance with ASC 260, shares issuable for little or no cash consideration are considered outstanding common shares and included in the computation of basic earnings per share. As such, the Company includes pre-funded warrants to purchase shares of common stock in its computation of earnings per share. The pre-funded warrants were issued in March 2024 and November 2019 with an exercise price of $0.001. See Note 11.
At December 31, 2024 and 2023, potentially dilutive shares outstanding amounted to 1,297,369 and 1,597,898 shares, respectively, and exclude pre-funded warrants to purchase shares of common stock.
Segment Information
Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information presented on a company-wide basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates as one operating segment. The Company has concluded that net income (loss) is the measure of segment profitability. The CODM assesses performance for the Company, monitors budget versus actual results, and determines how to allocate resources based on net income (loss) as reported in the statements of operations. There are no other expense categories regularly provided to the CODM that are not already included in the financial statements herein.
During the years ended December 31, 2024 and 2023, the Company did not generate material international revenues and as of December 31, 2024 and 2023, the Company did not have material assets located outside of the United States.
Stock Based Compensation
The Company applies FASB ASC 718, “Stock Compensation,” when recording stock-based compensation. Grants to non-employees are also accounted for under ASC 718. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option valuation model. The fair value of each performance stock unit award is estimated on the date of grant using a Monte Carlo simulation. The fair value of each restricted stock unit award is the closing pricing of the Company’s stock on the date of grant.
The Company issues common stock upon exercise of equity awards and warrants and upon the vesting of performance stock units and restricted stock units.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash with a major financial institution located in the United States. Balances are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company maintains balances in excess of federally insured limits. The Company has not experienced losses in such accounts and believes it is not exposed to significant credit risk regarding its cash and cash equivalents.
Recent Accounting Pronouncements
Management does not believe that any recently issued, but not yet effective, accounting standards, if adopted, would have a material impact on the Company’s financial statements. |

| Lessee, Operating Leases [Text Block] |
Note 7 — Lease
In March 2021, the Company entered into a lease agreement (the “Original Lease”) for 4,070 square feet of office and laboratory space located in Austin, Texas (the “Original Suite”). The commencement of the lease occurred on June 1, 2021 and the initial term of the lease was 63 months. The actual base rent in the first year of the lease was $56,471 and was net of $18,824 in abated rent over the first three months of the lease term. The annual base rent in the second year of the lease was $77,330 and increased by $2,035 in each succeeding year of the lease. In addition, the Company was required to pay its proportionate share of operating costs for the building under this triple net lease.
In April 2024, the Company entered into a first amendment and relocation agreement (the “Amended Lease”) with its landlord. Under the Amended Lease, the Company relocated to another, larger suite in the same office building. The Amended Lease is for 5,775 square feet of office and laboratory space (the “New Suite”) and, upon occupancy, replaced the 4,070 square feet of office and laboratory space previously leased by the Company. The term of the Amended Lease expires sixty-two (62) months from July 1, 2024, the commencement date. The annual base rent for the first year of the Amended Lease is $118,388 and the annual base rent increases approximately 2.75% each year during the lease term. The Company is required to pay its proportionate share of operating costs for the building under this triple net lease.
In accordance with ASC 842, the Company accounted for the modification of the lease contract as a separate lease contract. The lease for the Original Suite terminated on June 30, 2024 and the Company recorded a gain on the termination of the lease for the Original Suite of $15,319 in general and administrative expenses. The Company recognized a right of use asset of $524,025 and a corresponding lease liability for the Amended Lease on the commencement date. For purposes of calculating the right of use asset and lease liability, the Company estimated its incremental borrowing rate at 8.5% per annum.
Future minimum payments under the Amended Lease are as follows:
For the year ended December 31, 2024, operating cash outflows for lease payments totaled $99,046 and the operating lease cost, recognized on a straight-line basis, totaled $100,466. For the year ended December 31, 2023, operating cash outflows for lease payments totaled $78,517 and the operating lease cost, recognized on a straight-line basis, totaled $76,070. At December 31, 2024, the remaining lease term was 56 months.

Note 10 — Equity Incentive Plan
In May 2013, the Company adopted the 2013 Equity Incentive Plan (as amended and restated, the “Plan”) and reserved shares of common stock for issuance under the Plan, which was last amended in June 2023. The plan is administered by the Compensation Committee of the Company’s Board of Directors (the “Board”). At December 31, 2024, there were 256,267 shares of common stock available for issuance under the Plan.
During the year ended December 31, 2024, the Company granted 38,710 restricted stock units to Board members, 125,000 restricted stock units to executives and 128,922 restricted stock units to employees under the Plan. The estimated fair value of these equity grants was $2,072,676, of which $541,957 was recognized in the respective department expenses in the accompanying statement of operations for the year ended December 31, 2024.
During the year ended December 31, 2023, the Company granted 12,000 stock options to employees, 27,550 restricted stock units to Board members and 60,200 restricted stock units to employees under the Plan. During the year ended December 31, 2023, the Company granted no awards to executives under the Plan. The estimated fair value of these equity grants, calculated using the Black-Scholes option valuation model for the stock options, was $915,789, of which $363,563 was recognized in the respective department expenses in the accompanying statement of operations for the year ended December 31, 2023.
As permitted by SAB 107, management utilizes the simplified approach to estimate the expected term of stock options, which represents the period of time that options granted are expected to be outstanding. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. treasury yield in effect at the time of grant. The volatility is estimated based on the historical volatilities of comparable companies. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.
The assumptions used in the Black-Scholes model for the year ended December 31, 2023 are as follows:
No stock options were granted in the year ended December 31, 2024.
A summary of the Company’s stock option activity and related information is as follows:
The following table sets forth additional information about stock options outstanding at December 31, 2024:
Stock options granted under the Plan have ten-year terms and generally vest annually over a three-year vesting period except for option grants to independent directors that generally vest quarterly over a one-year vesting period.
The estimated aggregate pretax intrinsic value (the difference between the Company’s stock price on the last day of the year ended December 31, 2024 and the exercise prices, multiplied by the number of in-the-money options) is $1.0 million for both outstanding and vested options. This amount changes based on the fair value of the Company’s stock.
A summary of the Company’s restricted stock unit (“RSU”) and performance stock unit (“PSU”) activity is as follows:
In the year ended December 31, 2024, 130,447 restricted stock units vested of which 34,150 restricted stock units were forfeited to cover employee and executive payroll tax withholding obligations. In the year ended December 31, 2023, 99,886 restricted stock units vested of which 27,869 restricted stock units were forfeited to cover employee and executive payroll tax withholding obligations. The payment of the taxes on the vesting of the restricted stock units is shown as a financing activity on the accompanying statement of cash flow.
As of December 31, 2024, there was $2,282,686 of unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.1 years. |

Note 11 — Warrants
During the year ended December 31, 2024, the Company issued 633,332 pre-funded warrants with an exercise price of $0.001 and no expiration date. See Note 9.
During the year ended December 31, 2024, warrant holders exercised 444,180 warrants with a weighted average exercise price of $2.33 and 123,333 pre-funded warrants with an exercise price of $0.001.

| Income Tax Disclosure [Text Block] |
Note 12 — Income Taxes
Income taxes are disproportionate to income due to net operating loss carryforwards, which are fully reserved. As of December 31, 2024, the Company has federal net operating loss carryforwards of approximately $76 million. The federal net operating loss carryforward for years prior to 2018 expire from 2031 through 2038. Federal net operating loss carryforwards for year 2018 and thereafter do not expire.
Pursuant to Internal Revenue Code Sections 382 and 383, use of the Company’s net operating loss and credit carryforwards may be limited if a cumulative change in ownership of more than 50% occurs within any three-year period since the last ownership change. The Company may have had one or more changes in control under these Sections. However, the Company does not anticipate performing a complete analysis of the limitation on the annual use of the net operating loss and tax credit carryforwards until the time that it projects it will be able to utilize these tax attributes.
Management has concluded that it is more likely than not that the Company will not have sufficient foreseeable taxable income within the carryforward period as applicable and permitted by current law to allow for the utilization of certain of the deductible amounts generating the deferred tax assets; therefore, a full valuation allowance has been established to reduce the net deferred tax assets to zero at December 31, 2024 and 2023.
The following is a summary of the significant components of the Company’s net deferred income tax assets and liabilities as of December 31, 2024 and 2023:
The Company has applied the provisions of FASB ASC 740, Income Tax, which clarifies the accounting for uncertainty in tax positions. FASB ASC 740 requires the recognition of the impact of a tax position in the financial statements if that position is more likely than not of being sustained on a tax return upon examination by the relevant taxing authority, based on the technical merits of the position. At December 31, 2024 and 2023, the Company had no unrecognized tax benefits.
The Company recognizes interest and penalties related to income tax matters in interest expense and operating expenses, respectively. As of December 31, 2024 and 2023, the Company has no accrued interest and penalties related to uncertain tax positions.
The Company is subject to tax in the United States (“U.S.”) and files tax returns in the U.S. federal and certain state jurisdictions. The Company is generally no longer subject to U.S. federal, state and local income tax examinations by tax authorities for all tax years since inception due to the carryover of unused net operating losses and tax credits. The Company currently is not under examination by any tax authority.
The reconciliation between the statutory income tax rate and the effective tax rate is as follows:

Significant Accounting Policies (Policies) |
12 Months Ended | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Dec. 31, 2024 | ||||||||||||||||
| Accounting Policies [Abstract] | ||||||||||||||||
| Basis of Accounting, Policy [Policy Text Block] |
Basis of Presentation
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
|||||||||||||||
| Cash and Cash Equivalents, Policy [Policy Text Block] |
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. |
|||||||||||||||
| Accounts Receivable [Policy Text Block] |
Accounts Receivable
Trade accounts receivable are stated net of a provision for credit losses. The provision for credit losses represents an estimate of the lifetime expected credit losses inherent in trade receivables as of the balance sheet date. The Company assesses the adequacy of the provision for credit losses on a quarterly basis based on historical information and current economic conditions and forecasts. Subsequent changes in the provision for credit losses are recorded in current earnings and reversal of previous losses are permitted under the current guidance. While the Company believes it has exercised prudent judgment and applied reasonable assumptions, there can be no assurance that in the future, changes in economic conditions or other factors will not cause changes in the financial health of its customers. If the financial health of customers deteriorates, the timing and level of payments received could be impacted and therefore, could result in a change to the Company’s estimated losses.
Trade accounts receivable at December 31, 2024 relate to product sales. At December 31, 2024, the provision for credit losses was $0. |
|||||||||||||||
| Property, Plant and Equipment, Policy [Policy Text Block] |
Property and Equipment
Property and equipment are stated at historical cost less accumulated depreciation and amortization. Major additions and improvements are capitalized while maintenance and repairs that do not improve or extend the useful life of the respective asset are expensed. Depreciation and amortization of property and equipment is computed using the straight-line method over their estimated useful lives. Leasehold improvements are amortized over the shorter of the life of the asset or the related leases. Estimated useful lives of the principal classes of assets are as follows:
|
|||||||||||||||
| Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block] |
Intangible Assets
The Company’s intangible assets are composed of patents and trademarks, which are recorded at cost, and other intangible assets, which are recorded at cost plus the estimated present value of all future payments associated with the other intangible assets. The Company capitalizes third-party legal costs and filing fees, if any, associated with obtaining patents, trademarks or other intangible assets. Once the patent asset has been placed in service, the Company amortizes these costs over the shorter of the asset’s legal life, generally 20 years from the initial filing date, or its estimated economic life using the straight-line method. Trademarks are not amortized as trademarks have an indefinite useful life. For the other intangible assets, the Company amortizes the assets over the 11-year and 17‑year terms of the underlying agreements. |
|||||||||||||||
| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] |
Impairment of Long-Lived Assets
The long-lived assets, consisting of property and equipment and intangible assets, held and used by the Company are reviewed for impairment no less frequently than annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the event that facts and circumstances indicate that the cost of any long-lived assets may be impaired, an evaluation of recoverability is performed. Management has determined that there was an impairment in the value of long-lived assets in the amount of $77,444 during the year ended December 31, 2024. There were no impairments in the value of long-lived assets during the year ended December 31, 2023. |
|||||||||||||||
| Fair Value Measurement, Policy [Policy Text Block] |
Fair Value
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs used to establish fair value are the following:
The Company’s financial instruments primarily consist of cash and cash equivalents, accounts payable and long-term liabilities. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short-term nature of these instruments.
In 2015, the Company recorded a long-term liability for the estimated present value of future payments under licensing agreements. In 2021, the Company recorded an adjustment to increase the long-term liability due to an increase in the future payments due under these licensing agreements. In 2023, the Company recorded a long-term liability for the estimated present value of future payments under a separate licensing agreement. The Company determined the discount rate to estimate the present value of the future payments based on the applicable treasury rates. The Company’s long-term liability is classified within Level 3. See Note 5 and Note 8 for more details regarding the licensing agreements. The Company did not identify any other assets and liabilities that are required to be presented in the balance sheets at fair value. |
|||||||||||||||
| Revenue [Policy Text Block] |
Revenue Recognition
The Company recognizes revenue and related cost of revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers” and, as applicable, with the guidance issued by the FASB in June 2018 for the recipients of grants.
Commercial revenue relates to either the development agreements with customers or product sales. Commercial revenue under development agreements is generally recognized upon the completion of contractual deliverables. Commercial revenue from product sales is generally recognized upon shipment of products. Grant revenue relates to government contracts. Government contracts are agreements that generally provide the Company with cost reimbursement for certain types of development activities over a contractually defined period. Grant revenue is recognized in the period during which the Company incurs the related costs, provided that the Company has incurred the cost in accordance with the specifications and work plans determined between the Company and the government entity.
For the year ended December 31, 2024, the Company recognized $86,032 in commercial revenue and no grant revenue. For the year ended December 31, 2023, the Company recognized $161,483 of commercial revenue and $37,388 of grant revenue. |
|||||||||||||||
| Research and Development Expense, Policy [Policy Text Block] |
Research and Development
Research and development costs are presented as a line item under operating expenses and are expensed as incurred. Research and development costs include costs to further develop the Company’s B-TRAN® technology and related products and include, but are not limited to, the cost of engineering personnel, wafer fabrication, contract labor, driver design and fabrication, device packaging, product development, testing and other engineering services, stock-based compensation for engineering personnel, consulting and materials and supplies. |
|||||||||||||||
| Income Tax, Policy [Policy Text Block] |
Income Taxes
The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. At December 31, 2024 and 2023, the Company established a full reserve against all the net deferred tax assets.
Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. |
|||||||||||||||
| Earnings Per Share, Policy [Policy Text Block] |
Net Loss Per Share
The Company applies FASB ASC 260, “Earnings per Share.” Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include additional common shares available upon exercise of equity awards and warrants using the treasury stock method. In periods with a net loss, no common share equivalents are included because their effect would be anti-dilutive.
In accordance with ASC 260, shares issuable for little or no cash consideration are considered outstanding common shares and included in the computation of basic earnings per share. As such, the Company includes pre-funded warrants to purchase shares of common stock in its computation of earnings per share. The pre-funded warrants were issued in March 2024 and November 2019 with an exercise price of $0.001. See Note 11.
At December 31, 2024 and 2023, potentially dilutive shares outstanding amounted to 1,297,369 and 1,597,898 shares, respectively, and exclude pre-funded warrants to purchase shares of common stock. |
|||||||||||||||
| Segment Reporting, Policy [Policy Text Block] |
Segment Information
Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information presented on a company-wide basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates as one operating segment. The Company has concluded that net income (loss) is the measure of segment profitability. The CODM assesses performance for the Company, monitors budget versus actual results, and determines how to allocate resources based on net income (loss) as reported in the statements of operations. There are no other expense categories regularly provided to the CODM that are not already included in the financial statements herein.
During the years ended December 31, 2024 and 2023, the Company did not generate material international revenues and as of December 31, 2024 and 2023, the Company did not have material assets located outside of the United States. |
|||||||||||||||
| Share-Based Payment Arrangement [Policy Text Block] |
Stock Based Compensation
The Company applies FASB ASC 718, “Stock Compensation,” when recording stock-based compensation. Grants to non-employees are also accounted for under ASC 718. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option valuation model. The fair value of each performance stock unit award is estimated on the date of grant using a Monte Carlo simulation. The fair value of each restricted stock unit award is the closing pricing of the Company’s stock on the date of grant.
The Company issues common stock upon exercise of equity awards and warrants and upon the vesting of performance stock units and restricted stock units. |
|||||||||||||||
| Concentration Risk, Credit Risk, Policy [Policy Text Block] |
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash with a major financial institution located in the United States. Balances are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company maintains balances in excess of federally insured limits. The Company has not experienced losses in such accounts and believes it is not exposed to significant credit risk regarding its cash and cash equivalents. |

Recent Accounting Pronouncements
Management does not believe that any recently issued, but not yet effective, accounting standards, if adopted, would have a material impact on the Company’s financial statements. |
