Accounting Policies [Abstract]  
The interim financial data contained in this Report is unaudited; however in the opinion of management, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim period. The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures included herein are adequate to make the information presented not misleading.  The results of operations in interim periods are not necessarily indicative of the results that may be expected for the full year.
Information regarding the organization and business of the Company, accounting policies followed by the Company and other important information is contained in the notes to the Company's financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2017. This Report should be read in conjunction with the Company’s Annual Report.
The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions affecting the reported amounts of assets, liabilities, and expense, and the disclosure of contingent assets and liabilities. Estimated amounts could differ from actual results.
Loss per Common Share
The Financial Accounting Standards Board (FASB) has issued guidance for “Earnings Per Share” which provides for the calculation of “Basic” and “Diluted” earnings per share. Basic earnings per share includes no dilution and is computed by dividing net loss to common stockholders by the weighted average number of common shares outstanding for the period. All potentially dilutive securities consisting of employee stock options and warrants have been excluded from the computations since they would be antidilutive. However, these dilutive securities could potentially dilute earnings per share in the future. As of August 31, 2017 and August 31, 2016, the Company had potentially dilutive securities consisting of 3,980,543 and 3,982,543 stock options, respectively.
Cash and Cash Equivalents
For the purposes of reporting cash flows, the Company considers all cash accounts which are not subject to withdrawal restrictions or penalties, and highly liquid investments with original maturities of 90 days or less to be cash and cash equivalents. The cash and cash equivalent deposits are not insured by The Federal Deposit Insurance Corporation.
Certain reclassifications have been made to the prior periods to conform to the current presentations in the financial statements.
Research and Development
Research and development costs are expensed as incurred.
Share Based Compensation
Effective June 1, 2006, the Company adopted the FASB accounting guidance for fair value recognition provisions of the “Accounting for Share-Based Payment”. This standard requires the Company to measure the cost of employee services received in exchange for equity share options granted based on the grant-date fair value of the options. The cost is recognized as compensation expense over the vesting period of the options. The fair value of compensation costs attributed to equity rights issued was $0 and $180,333 and is included in operating expenses for the three months ended August 31, 2017 and August 31, 2016, respectively. These amounts included both the compensation cost of stock options granted prior to but not yet vested as of June 1, 2006 and compensation cost for all options granted subsequent to May 31, 2006. In accordance with the modified prospective application transition method, prior period results are not restated.  Incremental compensation cost for a modification of the terms or conditions of an award is measured by comparing the fair value of the modified award with the fair value of the award immediately before the modification. No tax benefit was recorded as of August 31, 2017 in connection with these compensation costs due to the uncertainty regarding ultimate realization of certain net operating loss carryforwards. The Company has also implemented the SEC interpretations in Staff Accounting Bulletin (SAB) for “Share-Based Payments,” in connection with the adoption of FASB accounting guidance.
The accounting guidance requires the use of a valuation model to calculate the fair value of each stock-based award. The Company uses the Black-Scholes model to estimate the fair value of stock options granted based on the following assumptions:
Expected Term or Life. The expected term or life of stock options granted issued represents the expected weighted average period of time from the date of grant to the estimated date that the stock option would be fully exercised. The weighted average expected option term was determined using a combination of the “simplified method” for plain vanilla options as allowed by the accounting guidance. The “simplified method” calculates the expected term as the average of the vesting term and original contractual term of the options.
Expected Volatility. Expected volatility is a measure of the amount by which the Company’s stock price is expected to fluctuate. Expected volatility is based on the historical daily volatility of the price of our common shares. The Company estimated the expected volatility of the stock options at grant date.
Risk-Free Interest Rate. The risk-free interest rate is based on the implied yield on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of our stock-based awards.
At August 31, 2017, there were 4,180,543 stock options outstanding, of which 3,980,543 were exercisable.  At August 31, 2017, the aggregate unrecognized compensation cost of unvested options, as determined using a Black-Scholes option valuation model, was $0.  The remaining options will be valued once they vest upon the future events. The Company did not grant any options during the three months ended August 31, 2017, and 400,000 options expired.
