Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS	NOTE 1 – DESCRIPTION OF BUSINESS Rafael Holdings, Inc. (“Rafael Holdings” or the “Company”), a Delaware corporation, owns interests in pre-clinical and clinical stage pharmaceutical companies and commercial real estate assets. The assets are operated as two separate lines of business. The pharmaceutical holdings include preferred and common equity interests and a warrant to purchase additional equity interests in Rafael Pharmaceuticals, Inc., or Rafael Pharmaceuticals, which is a clinical stage, oncology-focused pharmaceutical company committed to the development and commercialization of therapies that exploit the metabolic differences between normal cells and cancer cells; and, a majority equity interest in LipoMedix Pharmaceuticals Ltd., or LipoMedix, a clinical stage oncological pharmaceutical company based in Israel. In addition, in 2019, the Company established the Barer Institute (“Barer”), a wholly-owned early stage venture focused on developing a pipeline of therapeutic compounds, including compounds to regulate cancer metabolism. The venture is pursuing collaborative research agreements with leading scientists from top academic institutions. In addition, the Company has recently initiated efforts to develop other early stage pharmaceutical ventures including Levco Pharmaceuticals Ltd. (“Levco”), an Israeli company, established to partner with Dr. Alberto Gabizon and a top institution in Israel on the development of novel compounds for cancer, and Farber Partners, LLC (“Farber”), formed around an agreement with Princeton University’s Office of Technology Licensing for technology from the laboratory of Professor Joshua Rabinowitz, in the Department of Chemistry, Princeton University, for an exclusive worldwide license to its SHMT (serine hydroxymethyltransferase) inhibitor program. Additionally, in 2021, the Company established Rafael Medical Devices, LLC (“Rafael Medical Devices”), a wholly-owned orthopedic device company developing instruments and implants to advance minimally invasive surgeries in the upper and lower extremities. The commercial real estate holdings consist of a building at 520 Broad Street in Newark, New Jersey that serves as headquarters for the Company and certain other entities and hosts other tenants and an associated 800-car public garage, and a portion of a building in Israel. In August 2020, the Company sold an office/data center building in Piscataway, New Jersey, which was classified as held for sale at July 31, 2020. The “Company” in these consolidated financial statements refers to Rafael Holdings on a consolidated basis. All significant intercompany accounts and transactions have been eliminated in consolidation. All majority-owned subsidiaries are consolidated with all intercompany transactions and balances eliminated in consolidation or combination.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. The Company’s fiscal year ends on July 31 of each calendar year. Each reference below to a fiscal year refers to the fiscal year ending in the calendar year indicated (e.g., fiscal 2020 refers to the fiscal year ended July 31, 2020). Operating results for the three and nine months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2021. The balance sheet at July 31, 2020 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended July 31, 2020, or the 2020 Form 10-K, as filed with the U.S. Securities and Exchange Commission (the “SEC”). Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ significantly from those estimates. Liquidity Management believes that its cash on hand, planned forecast, and expected ability to meet its obligations alleviates the substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date of the issuance of these financial statements. The Company has no outstanding long term debt due within 12 months and has cash reserves which will enable it to meet obligations for over a year, without attempt to monetize assets via increasing building occupancy or selling assets. The Company can liquidate its investments in hedge funds to generate cash if needed, and the Company could consider alternative sources of funding if necessary. Risks and Uncertainties - COVID-19 In December 2019, a new coronavirus, now known as COVID-19, which has proved to be highly contagious, has since spread around the globe. The Company actively monitors the outbreak and its potential impact on its operations and those of the Company’s holdings. The impacts on the Company’s and its affiliates’ operations and specifically the ongoing clinical trials of the Company’s pharmaceutical holdings have been actively managed by respective pharmaceutical management teams who have worked closely with the appropriate regulatory agencies to continue clinical trial activities with as minimal impact as possible including receiving waivers for certain clinical trial activities from the respective regulatory agencies to continue the studies. Although partially mitigated recently, there remains a general degree of uncertainty in the national commercial real estate market based on the COVID-19 pandemic and as a result there remains a potential impact to the value of the Company’s real estate portfolio as well as efforts to monetize those assets. The Company has implemented a number of measures to protect the health and safety of the Company’s workforce including a voluntary work-from-home policy for the Company’s workforce who can perform their jobs from home as well as restrictions on business travel. Due to both known and unknown risks, including quarantines, closures and other restrictions resulting from the outbreak, operations and those of the Company’s holdings may be adversely impacted. Additionally, as there is an evolving nature to the COVID-19 situation, the Company cannot reasonably assess or predict at this time the full extent of the negative impact that the COVID-19 pandemic may have on the Company’s business, financial condition, results of operations and cash flows. The impact will depend on future developments such as the ultimate duration and the severity of the spread of the COVID-19 pandemic in the U.S. and globally, the effectiveness of federal, state, local and foreign government actions on mitigation and spread of COVID-19, the pandemic’s impact on the U.S. and global economies, changes in the Company’s customers’ behavior emanating from the pandemic and how quickly the Company can resume our normal operations, among others. For all these reasons, the Company may incur expenses or delays relating to such events outside of the Company’s control, which could have a material adverse impact on the Company’s business. Investments The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled affiliates. All significant intercompany accounts and transactions between the consolidated affiliates are eliminated. Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. Investments in which the Company does not have the ability to exercise significant influence over operating and financial matters are accounted for using the cost method. The Company periodically evaluates its investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded in the accompanying consolidated statements of operations and comprehensive loss, and a new basis in the investment is established. Variable Interest Entities In accordance with Accounting Standards Codification (“ASC”) 810, Consolidation If an entity is determined to be a VIE, the Company evaluates whether the Company is the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. The Company consolidates a VIE if both power and benefits belong to the Company – that is, the Company (i) has the power to direct the activities of a VIE that most significantly influence the VIE’s economic performance (power), and (ii) has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE (benefits). The Company consolidates VIEs whenever it is determined that the Company is the primary beneficiary. Cost Method Investments Equity Method Investments Revenue Recognition The Company applies the five-step approach as described in ASC 606, Revenue from Contracts with Customers The Company disaggregates its revenue by source within its consolidated statements of operations and comprehensive loss. As an owner and operator of real estate, the Company derives the majority of its revenue from leasing office and parking space to tenants at its properties. In addition, the Company earns revenue from recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs. Revenue from recoveries from tenants is recorded together with rental income on the consolidated statements of operations and comprehensive loss which is also consistent with the guidance under ASC 842, Leases Contractual rental revenue is reported on a straight-line basis over the terms of the respective leases. Accrued rental income, included within other assets on the consolidated balance sheets, represents cumulative rental income earned in excess of rent payments received pursuant to the terms of the individual lease agreements. The Company also earns revenue from parking which is derived primarily from monthly and transient daily parking. The monthly and transient daily parking revenue falls within the scope of ASC 606 and is accounted for at the point in time when control of the goods or services transfers to the customer and the Company’s performance obligation is satisfied, consistent with the Company’s previous accounting. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required rent payments or parking customers to pay amounts due. Research and Development Costs Research and development costs and expenses incurred by consolidated entities consist primarily of salaries and related personnel expenses, stock-based compensation, fees paid to external service providers, laboratory supplies, costs for facilities and equipment, license costs, and other costs for research and development activities. Research and development expenses are recorded in operating expenses in the period in which they are incurred. Estimates have been used in determining the liability for certain costs where services have been performed but not yet invoiced. The Company monitors levels of performance under each significant contract for external service providers, including the extent of patient enrollment and other activities through communications with the service providers to reflect the actual amount expended. Contingent milestone payments associated with acquiring rights to intellectual property are recognized when probable and estimable. These amounts are expensed to research and development when there is no alternative future use associated with the intellectual property.

A trust for the benefit of the children of Howard Jonas (Chairman of the Board and former Chief Executive Officer of the Company and former Chairman of the Board of Rafael Pharmaceuticals) holds a financial instrument (the “Instrument”) that owns 10% of Pharma Holdings. Pharma Holdings holds 36.7 million shares of Rafael Pharmaceuticals Series D Convertible Preferred Stock and a warrant to increase the combined ownership of Pharma Holdings and CS Pharma to up to 56% of the fully diluted equity interests in Rafael Pharmaceuticals (the “Warrant”). The Warrant is exercisable at the lower of 70% of the price sold in an equity financing, or $1.25 per share, subject to certain adjustments. On March 25, 2020, the Board of Directors of Rafael Pharmaceuticals extended the expiration date of the Warrant held by Pharma Holdings to purchase shares of the Warrant from December 31, 2020 to June 30, 2021 and on August 31, 2020, the Board of Directors of Rafael Pharmaceuticals further extended the expiration date of the Warrant held by Pharma Holdings, LLC to purchase shares of the Warrant to August 15, 2021. Pharma Holdings also holds certain governance rights in Rafael Pharmaceuticals including appointment of directors. CS Pharma holds 16.7 million shares of Rafael Pharmaceuticals Series D Convertible Preferred Stock. CS Pharma owned a $10 million Series D Convertible Note, with 3.5% interest, in Rafael Pharmaceuticals which was converted in January 2019. The Company and its subsidiaries collectively own securities representing 51% of the outstanding capital stock of Rafael Pharmaceuticals and 41% of the capital stock on a fully diluted basis (excluding the remainder of the Warrant). The Series D Convertible Preferred Stock has a stated value of $1.25 per share (subject to appropriate adjustment to reflect any stock split, combination, reclassification or reorganization of the Series D Preferred Stock or any dilutive issuances, as described below). Holders of Series D Stock are entitled to receive non-cumulative dividends when, as and if declared by the board of Rafael Pharmaceuticals, prior to any dividends to any other class of capital stock of Rafael Pharmaceuticals. In the event of any liquidation, dissolution or winding up of the Company, or in the event of any deemed liquidation, proceeds from such liquidation, dissolution or winding up shall be distributed first to the holders of Series D Stock. Except with respect to certain major decisions, or as required by law, holders of Series D Stock vote together with the holders of the other preferred stock and common stock and not as a separate class. The Company serves as the managing member of Pharma Holdings, and Pharma Holdings serves as the managing member of CS Pharma, with broad authority to make all key decisions regarding their respective holdings. Any distributions that are made to CS Pharma from Rafael Pharmaceuticals that are in turn distributed by CS Pharma, will need to be made pro rata to all members, which would entitle Pharma Holdings to 50% (based on current ownership) of such distributions. Similarly, if Pharma Holdings were to distribute proceeds it receives from CS Pharma, it would do so on a pro rata basis, entitling the Company to 90% (based on current ownership) of such distributions. The Company evaluated its investments in Rafael Pharmaceuticals in accordance with ASC 323, Investments - Equity Method and Joint Ventures, Rafael Pharmaceuticals is a VIE; however, the Company has determined that it is not the primary beneficiary as it does not have the power to direct the activities of Rafael Pharmaceuticals that most significantly impact Rafael Pharmaceuticals’ economic performance. In addition, the interests held in Rafael Pharmaceuticals are Series D Convertible Preferred Stock and do not represent in-substance common stock. The Instrument has additional contractual rights to receive additional Rafael Pharmaceuticals shares (“Bonus Shares”) for an additional 10% of the fully diluted capital stock of Rafael Pharmaceuticals upon the achievement of certain milestones. The additional 10% is based on the fully diluted capital stock of Rafael Pharmaceuticals, excluding the remainder for the Warrant, at the time of issuance. If any of the milestones are met, the Bonus Shares are to be issued without any additional payment. Pharma Holdings holds the Warrant to purchase a significant stake in Rafael Pharmaceuticals, as well as other equity and governance rights in Rafael Pharmaceuticals. The Company currently owns 51% of the issued and outstanding equity in Rafael Pharmaceuticals. Approximately 8% of the issued and outstanding equity is owned by the Company’s subsidiary CS Pharma and 43% is held by the Company’s subsidiary Pharma Holdings. The Company’s subsidiary Pharma Holdings holds the Warrant, which is non-dilutable and provides for the Company to increase its (via Pharma Holdings and CS Pharma and inclusive of the interests held by the other owners of those entities) total ownership to 56%. Based on the current shares issued and outstanding of Rafael Pharmaceuticals as of April 30, 2021, the Company, and the Company’s affiliates, would need to pay approximately $17 million to exercise the Warrant in full to 56%. On an as-converted fully diluted basis (for all convertible securities of Rafael Pharmaceuticals outstanding), the Company and the Company’s affiliates would need to pay approximately $126 million to exercise the Warrant in full (including to offset the impact of additional issuances of Rafael Pharmaceuticals equity under the Line of Credit). The Instrument holds 10% of the interest in Pharma Holdings and would need to contribute 10% of any cash necessary to exercise any portion of the Warrant. Following any exercise, a portion of the Company’s interest in Rafael Pharmaceuticals would continue to be held for the benefit of the other equity holders in Pharma Holdings and CS Pharma. Given the Company’s anticipated available cash, the Company would not be able to exercise the Warrant in its entirety and the Company may never be able to exercise the Warrant in full. Rafael Pharmaceuticals may also issue additional equity interests, such as employee stock options, which will require the Company to pay additional cash to maintain the Company’s ownership percentage or exercise the Warrant in full. On January 28, 2021, Pharma Holdings partially exercised the Warrant to maintain the 51% ownership percentage and purchased 7.3 million shares of Rafael Pharmaceuticals’ Series D Preferred Stock for $9.1 million, of which $0.9 million was contributed by the holder of a minority interest in Pharma Holdings.

FAIR VALUE MEASUREMENTS	NOTE 7 – FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value: ● Level 1 ● Level 2 ● Level 3 The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following is a listing of the Company’s assets required to be measured at fair value on a recurring basis and where they are classified within the fair value hierarchy as of April 30, 2021 and July 31, 2020: April 30, 2021 Level 1 Level 2 Level 3 Total Assets: (unaudited, in thousands) Hedge Funds $ — $ — $ 9,681 $ 9,681 Total $ — $ — $ 9,681 $ 9,681 July 31, 2020 Level 1 Level 2 Level 3 Total Assets: (in thousands) Hedge Funds $ — $ — $ 7,510 $ 7,510 Total $ — $ — $ 7,510 $ 7,510 At April 30, 2021 and July 31, 2020, the Company did not have any liabilities measured at fair value on a recurring basis.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. The fair value of these assets is estimated based on information provided by the fund managers or the general partners. Therefore, these assets are classified as Level 3. In October 2020, the Company received a $2 million distribution of the Company’s investments in Hedge Funds. The Company holds $0.5 million in investments in securities in another entity that are not liquid, which were included in Investments - Other Pharmaceuticals in the accompanying consolidated balance sheets. The investment is accounted for under ASC 321, Investments - Equity Securities Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting these data to develop estimates of fair value.

Earnings Per Share [Abstract]
LOSS PER SHARE	NOTE 10 – LOSS PER SHARE Basic net loss per share is computed by dividing net loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted loss per shares includes potentially dilutive securities such as stock options, warrants to purchase common stock, and other convertible instruments unless the result of inclusion would be anti-dilutive. These securities have been excluded from the calculation of diluted net loss per shares for the three and nine months ended April 30, 2021 and 2020 because all such securities are anti-dilutive for all periods presented. The following table summarizes the Company’s potentially dilutive securities, in common share equivalents, which have been excluded from the calculation of dilutive loss per share as their effect would be anti-dilutive: Three months ended Nine months ended 2021 2020 2021 2020 Shares issuable upon exercise of stock options 689,210 580,874 689,210 580,874 Shares issuable upon exercise of warrants to purchase Class B common stock 26,189 — 26,189 — The diluted loss per share computation equals basic loss per share for the three and nine months ended April 30, 2021 and 2020 because the Company had a net loss and the impact of the assumed exercise of stock options and warrants would have been anti-dilutive.

All investments in Rafael Pharmaceuticals and assets and expenses associated with LipoMedix, Barer, Levco, Farber, and Rafael Medical Devices are tracked separately in the Pharmaceuticals segment. All corporate costs are allocated to the Real Estate segment. The Pharmaceuticals segment is comprised of preferred and common equity interests and the Warrant to purchase equity interests in Rafael Pharmaceuticals, a majority equity interest in LipoMedix, Barer, Levco, Farber, and Rafael Medical Devices. To date, the Pharmaceuticals segment has not generated any revenues. The Real Estate segment consists of the Company’s real estate holdings, including a building at 520 Broad Street in Newark, New Jersey that houses headquarters for the Company and certain affiliates and its associated public garage and a portion of an office building in Israel. In August 2020, the Company sold a 3-story, 65,253 square foot office building located at 225 Old New Brunswick Road in Piscataway, New Jersey to 225 ONBR, LLC, an entity unaffiliated with the Company. The purchase price was $3,875,000 and, after transfer taxes and broker’s commission, the Company received $3,658,000 in cash. At July 31, 2020, the building was classified as held for sale on the consolidated balance sheet.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 14 – COMMITMENTS AND CONTINGENCIES Legal Proceedings On September 17, 2018, LipoMedix was notified of a claim initiated by one of its founders seeking payment of consulting fees in the amount of approximately $377,000 and seeking to place restrictions on LipoMedix’s bank accounts and other assets to protect his claim. LipoMedix did not believe that the individual had the right to receive any payment at the current time. LipoMedix responded to the demand for the placement of restrictions on its assets. In May 2019, LipoMedix received a letter from the other founder requesting payment of his consulting fees. On July 15, 2019, the parties settled the matters and the two founders will be paid a percentage of future investments and certain other proceeds. On July 12, 2019, the Company received a Citation and Notification of Penalty from the Occupational Safety and Health Administration of the U.S. Department of Labor, or OSHA, related to an OSHA inspection of 520 Broad Street, Newark, New Jersey. The citation seeks to impose penalties related to alleged violations of the Occupation Safety and Health Act of 1970 at 520 Broad Street. On July 31, 2019, the Company filed a Notice of Contest with OSHA contesting the citation in its entirety. On February 14, 2020, the Company entered into a Settlement Agreement with OSHA, as related to the citation received on July 12, 2019. As part of the Settlement Agreement, the Company agreed to pay a penalty of $127,294 in eight quarterly installment payments through November 2021, which the Company accrued for and has an outstanding balance of approximately $32,000 as of April 30, 2021. As the Company accounts for contingencies when a loss is considered probable and can be reasonably estimated, the accrued balance is for legal fees and losses believed to be both probable and reasonably estimable, but an exposure to additional loss may exist in excess of the amount accrued. On December 31, 2019, an employee of the Company filed a complaint in connection with the incident that led to the OSHA inspection noted above for personal injuries against the Company and other parties in the New Jersey Supreme Court for an incident that took place on January 31, 2019 at 520 Broad Street, Newark, New Jersey. The Company intends to vigorously defend this matter. The loss is considered remote and no accrual has been recorded. The Company may from time to time be subject to legal proceedings that may arise in the ordinary course of business. Although there can be no assurance in this regard, other than noted above, the Company does not expect any of those legal proceedings to have a material adverse effect on the Company’s results of operations, cash flows or financial condition.

Stockholders' Equity Note [Abstract]
EQUITY	NOTE 15 – EQUITY On November 15, 2018, Howard Jonas entered into an agreement to purchase a convertible note from the Company for $15.0 million that was convertible into shares of Class B common stock at $8.47 per share. The term of the note was three years with interest on the principal amount at a rate of 6% per annum, compounded quarterly. In August 2019, the note, including interest of approximately $667,000 was converted into 1,849,749 shares of Class B common stock. Pursuant to the Company’s 2018 Equity Incentive Plan, three of the Company’s four non-employee directors of the Company were granted 4,203 restricted shares of Class B common stock in January 2021 and 4,203 restricted shares of Class B common stock in January 2020 which fully vested on the date of the grants. The fair value of the awards on the date of the grants were approximately $286,000 and $208,000 in January 2021 and January 2020, respectively, which was included in Selling, General and Administrative Expense. Stock Options A summary of stock option activity for the Company is as follows: Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding at July 31, 2020 580,874 $ 4.90 2.65 $ 5,269 Granted 118,409 40.85 10.00 176 Exercised (8,750 ) 4.90 Cancelled / Forfeited (1,323 ) — Outstanding at April 30, 2021 689,210 $ 11.08 3.29 $ 21,547 Exercisable at April 30, 2021 570,801 $ 4.90 1.91 $ 21,371 During April 2021, 118,409 options were granted to one individual, resulting in $0.7 million in stock-based compensation expense for the three months ended April 30, 2021. These options are subject to graded vesting extending through April 15, 2025. During the nine months ended April 30, 2021, 8,750 options were exercised. At April 30, 2021, there was unrecognized compensation cost related to non-vested stock options of $2.9 million, which is expected to be recognized over the next 2.1 years. Restricted Stock The fair value of restricted shares of the Company’s Class B common stock is determined based on the closing price of the Company’s Class B common stock on the grant date. Share awards generally vest on a graded basis over three years of service. A summary of the status of the Company’s grants of restricted shares of Class B common stock is presented below: Number of Non-vested Shares Weighted Average Grant Date Outstanding at July 31, 2020 123,104 $ 10.80 Granted 44,070 21.92 Vested (69,347 ) 10.76 Cancelled / Forfeited (2,099 ) 13.54 Non-vested shares at April 30, 2021 95,728 $ 15.28 At April 30, 2021, there was $1.6 million of total unrecognized compensation cost related to non-vested stock-based compensation arrangements, which is expected to be recognized over the next 2.4 years. Share Purchase Agreement On December 7, 2020, Rafael Holdings entered into a Securities Purchase Agreement (the “SPA”) for the sale of 567,437 shares of the Company’s Class B common stock at a price per share of $22.91 (which was the closing price for the Class B common stock on the New York Stock Exchange on December 4, 2020, the trading day immediately preceding the date of the SPA) for an aggregate purchase price of $13 million. Approximately $8.2 million of the proceeds received pursuant to the SPA were used by the Company to exercise an additional portion of the Warrant in order to maintain the Company’s relative position in Rafael Pharmaceuticals in light of issuances of Rafael Pharmaceuticals equity securities to third-party shareholders of Rafael Pharmaceuticals, due to warrant exercises by these shareholders. The Company is using the remaining proceeds to fund the operations of its drug development programs including its Barer Institute subsidiary, and for general corporate purposes. Under the SPA, two entities, on whose Boards of Directors Howard Jonas, the Registrant’s Chairman of the Board and former Chief Executive Officer serves, each purchased 218,245 shares of Class B common stock for consideration of $5 million each. The shares and warrants were issued in reliance on the exemption from registration provided for under Section 4(a)(2) of the Securities Act of 1933, as amended. Equity-classified Warrants In connection with the Share Purchase Agreement, each purchaser was granted warrants to purchase twenty percent (20%) of the shares of Class B common stock purchased by such purchaser. The Company issued warrants to purchase 113,487 shares of Class B common stock to the purchasers. The warrants are exercisable at a per share exercise price of $22.91, and are exercisable at any time on or after December 7, 2020 through June 6, 2022. The Company determined that these warrants are equity-classified. During the three months ended April 30, 2021, IDT and Genie Energy, Ltd each exercised 43,649 warrants, resulting in a total of 87,298 shares of Class B common stock issued for proceeds of approximately $2 million. At April 30, 2021, the Company had outstanding warrants to purchase 26,189 shares of Class B common stock at an exercise price of $22.91 per share, all of which expire June 6, 2022.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. The Company’s fiscal year ends on July 31 of each calendar year. Each reference below to a fiscal year refers to the fiscal year ending in the calendar year indicated (e.g., fiscal 2020 refers to the fiscal year ended July 31, 2020). Operating results for the three and nine months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2021. The balance sheet at July 31, 2020 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended July 31, 2020, or the 2020 Form 10-K, as filed with the U.S. Securities and Exchange Commission (the “SEC”).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ significantly from those estimates.
Liquidity	Liquidity Management believes that its cash on hand, planned forecast, and expected ability to meet its obligations alleviates the substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date of the issuance of these financial statements. The Company has no outstanding long term debt due within 12 months and has cash reserves which will enable it to meet obligations for over a year, without attempt to monetize assets via increasing building occupancy or selling assets. The Company can liquidate its investments in hedge funds to generate cash if needed, and the Company could consider alternative sources of funding if necessary.
Risks and Uncertainties - COVID-19	Risks and Uncertainties - COVID-19 In December 2019, a new coronavirus, now known as COVID-19, which has proved to be highly contagious, has since spread around the globe. The Company actively monitors the outbreak and its potential impact on its operations and those of the Company’s holdings. The impacts on the Company’s and its affiliates’ operations and specifically the ongoing clinical trials of the Company’s pharmaceutical holdings have been actively managed by respective pharmaceutical management teams who have worked closely with the appropriate regulatory agencies to continue clinical trial activities with as minimal impact as possible including receiving waivers for certain clinical trial activities from the respective regulatory agencies to continue the studies. Although partially mitigated recently, there remains a general degree of uncertainty in the national commercial real estate market based on the COVID-19 pandemic and as a result there remains a potential impact to the value of the Company’s real estate portfolio as well as efforts to monetize those assets. The Company has implemented a number of measures to protect the health and safety of the Company’s workforce including a voluntary work-from-home policy for the Company’s workforce who can perform their jobs from home as well as restrictions on business travel. Due to both known and unknown risks, including quarantines, closures and other restrictions resulting from the outbreak, operations and those of the Company’s holdings may be adversely impacted. Additionally, as there is an evolving nature to the COVID-19 situation, the Company cannot reasonably assess or predict at this time the full extent of the negative impact that the COVID-19 pandemic may have on the Company’s business, financial condition, results of operations and cash flows. The impact will depend on future developments such as the ultimate duration and the severity of the spread of the COVID-19 pandemic in the U.S. and globally, the effectiveness of federal, state, local and foreign government actions on mitigation and spread of COVID-19, the pandemic’s impact on the U.S. and global economies, changes in the Company’s customers’ behavior emanating from the pandemic and how quickly the Company can resume our normal operations, among others. For all these reasons, the Company may incur expenses or delays relating to such events outside of the Company’s control, which could have a material adverse impact on the Company’s business.
Investments	Investments The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled affiliates. All significant intercompany accounts and transactions between the consolidated affiliates are eliminated. Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. Investments in which the Company does not have the ability to exercise significant influence over operating and financial matters are accounted for using the cost method. The Company periodically evaluates its investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded in the accompanying consolidated statements of operations and comprehensive loss, and a new basis in the investment is established.
Variable Interest Entities	Variable Interest Entities In accordance with Accounting Standards Codification (“ASC”) 810, Consolidation If an entity is determined to be a VIE, the Company evaluates whether the Company is the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. The Company consolidates a VIE if both power and benefits belong to the Company – that is, the Company (i) has the power to direct the activities of a VIE that most significantly influence the VIE’s economic performance (power), and (ii) has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE (benefits). The Company consolidates VIEs whenever it is determined that the Company is the primary beneficiary. Cost Method Investments Equity Method Investments
Revenue Recognition	Revenue Recognition The Company applies the five-step approach as described in ASC 606, Revenue from Contracts with Customers The Company disaggregates its revenue by source within its consolidated statements of operations and comprehensive loss. As an owner and operator of real estate, the Company derives the majority of its revenue from leasing office and parking space to tenants at its properties. In addition, the Company earns revenue from recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs. Revenue from recoveries from tenants is recorded together with rental income on the consolidated statements of operations and comprehensive loss which is also consistent with the guidance under ASC 842, Leases Contractual rental revenue is reported on a straight-line basis over the terms of the respective leases. Accrued rental income, included within other assets on the consolidated balance sheets, represents cumulative rental income earned in excess of rent payments received pursuant to the terms of the individual lease agreements. The Company also earns revenue from parking which is derived primarily from monthly and transient daily parking. The monthly and transient daily parking revenue falls within the scope of ASC 606 and is accounted for at the point in time when control of the goods or services transfers to the customer and the Company’s performance obligation is satisfied, consistent with the Company’s previous accounting. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required rent payments or parking customers to pay amounts due.
Research and Development Costs	Research and Development Costs Research and development costs and expenses incurred by consolidated entities consist primarily of salaries and related personnel expenses, stock-based compensation, fees paid to external service providers, laboratory supplies, costs for facilities and equipment, license costs, and other costs for research and development activities. Research and development expenses are recorded in operating expenses in the period in which they are incurred. Estimates have been used in determining the liability for certain costs where services have been performed but not yet invoiced. The Company monitors levels of performance under each significant contract for external service providers, including the extent of patient enrollment and other activities through communications with the service providers to reflect the actual amount expended. Contingent milestone payments associated with acquiring rights to intellectual property are recognized when probable and estimable. These amounts are expensed to research and development when there is no alternative future use associated with the intellectual property.
