Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A) BASIS OF PRESENTATION The condensed consolidated balance sheet as of March 31, 2020 , the condensed consolidated statements of operations for the three and nine months ended March 31, 2020 , the condensed consolidated statements of cash flows for the nine months ended March 31, 2020 and the condensed consolidated statements of stockholders' equity for the three and nine months ended March 31, 2020 and 2019 , have been prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and have not been audited. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for all periods presented have been made. The operating results for any interim period are not necessarily indicative of the operating results that may be experienced for the full fiscal year. Certain information and footnote disclosure normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10 -K for the fiscal year ended June 30, 2019 . The preparation of financial statements in conformity with U.S. GAAP requires the company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses. Significant estimates and assumptions are used for, but are not limited to, allowances for doubtful accounts, reserves for excess and obsolete inventories, long-lived and intangible assets, income tax valuation allowance , non-cash stock-based compensation and deferred compensation. Actual results could differ from the Company's estimates. B) INCOME TAXES A state tax provision of $6,104 and $6,125 was recorded during the three and nine months ended March 31, 2020 , respective ly. There was no state tax provision for the three and nine months ended March 31, 2019. Utilization of net operating tax carryforwards and a full valuation allowance against deferred tax assets reduced the federal income tax expense to zero for the three and nine months ended March 31, 2020 and 2019 . F or the three and nine months ended March 31, 2019 , the Company recorded an income tax benefit of $23,020 and $22,995 , respectively, due to refund of the AMT credits not recognized in prior years. This refund was allowed under the Tax Cuts and Jobs Act of 2017. C) PATENT COSTS The Company incurs on-going legal fees and filing costs related to the patent portfolio. These costs are expensed in the period they are incurred since no patent legal costs were probable to provide a future economic benefit .

Note 2 - Change in Accounting Principle

Accounting Standards Update and Change in Accounting Principle [Text Block]

CHANGE IN ACCOUNTING PRINCIPLE

During

the

first

quarter of fiscal

2020,

the Company changed its method of recording stock-based compensation expense. Under the new accounting principle, stock-based compensation expense is recorded on a straight-line basis over the vesting period and forfeitures are recognized when they occur. Under the previous method, the Company estimated future forfeitures and the expected number of awards that would vest and subsequently adjusted for forfeitures. The Company believes this method of recording stock-based compensation expense on a straight-line basis over the vesting period is preferable since it is more reflective of the stock options that will actually vest.

The cumulative effect of the changes in the

June 30, 2019

Consolidated Balance Sheet for the change in principle related to stock-based compensation expense using the full retrospective method was as follows:

			Stock-Based
Balance Sheet	As Previously		Compensation			As
June 30, 2019	Reported		Adjustment			Adjusted
Equity:
Paid in capital	$	6,186,393	$	146,742		$	6,333,135
Retained earnings	$	8,848,684	$	(146,742	)	$	8,701,942

The impact of the change in principle on the Consolidated Statement of Operations for the

three

and

nine

months ended

March 31, 2019

was as follows:

			Stock-Based

3.03

years, was

$1,366,897.
