Defined Contribution Plan	Note 21. Defined Contribution Plan For U.S. employees, during 2011, the Company began sponsoring a 401(k) defined contribution plan ("401(k) Plan") that provides for a 100.0% employer matching contribution of the first 4.0% of eligible pay that the employee contributed to the plan. Employees are immediately 100.0% vested in the Company’s non-discretionary contribution to the 401(k) Plan. The Company's 401(k) matching contributions were $84,426 and $27,244 in the years ended December 31, 2020 and 2019, respectively. Full time employees in the PRC participate in a government-mandated defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. PRC labor regulations require the Company to make contributions based on certain percentages of the employees’ basic salaries. Other than such contributions, there is no further obligation under these plans. The total contributions for such PRC employee benefits were $0.4 million and $0.4 million in the years ended December 31, 2020 and 2019, respectively.
