Patents, net consist of the following:

        
   March 31, 2023   March 31, 2022 
Issued patents  $157,442   $157,442 
Accumulated amortization   (155,792)   (155,242)
Issued patents, net of accumulated amortization   1,650    2,200 
Patents pending        
Patents, net  $1,650   $2,200 

 

Amortization expense for our capitalized issued patents for each of the fiscal years ended March 31, 2023 and 2022 was $550 and $54,754, 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 3 years.
