Amortization expense for our capitalized issued patents for each of the fiscal years ended March 31, 2022 and 2021 was $54,754 and $550, respectively. As only one capitalized patent remains to be amortized, future amortization expense on patents is estimated to be approximately $550 per year based on the estimated life of the patent. The weighted average remaining life of our remaining capitalized patent is approximately 4 years.
