Income Tax Disclosure [Text Block] | 14. Income Taxes The Company’s effective tax rate is approximately 0.3% and 0.3% for the six-month periods ended June 30, 2026 and 2025, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the six-month periods ended June 30, 2026 and 2025 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the six-month periods ended June 30, 2026 and 2025.
