Income Taxes	12 Months Ended
	Dec. 31, 2022
Narrative [Abstract]
Income Tax Disclosure [Text Block]	Income TaxesWe did not incur an income tax liability for the years ended December 31, 2021 and 2020 and we do not expect to incur an income tax liability for the year ended December 31, 2022. Based on our analysis of any potential uncertain income tax positions, we concluded that we do not have any uncertain tax positions that meet the recognition or measurement criteria of ASC Topic 740, Income Taxes, as of December 31, 2022 or prior periods. Our tax returns for tax years 2019 and forward are open to examination by the IRS. If we incur income tax related interest and penalties, our policy is to classify them as a component of provision for income taxes.
