Patents, net consist of the following:

	March 31, 2024			March 31, 2023
Issued patents	$	157,442		$	157,442
Accumulated amortization		(156,342	)		(155,792	)
Issued patents, net of accumulated amortization		1,100			1,650
Patents, net	$	1,100		$	1,650

Amortization expense for our capitalized issued patents for each of the fiscal years ended March 31, 2024 and 2023 was $550. 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 2.0 years.
