Income Taxes	9 Months Ended
Jul. 31, 2017
Income Tax Disclosure [Abstract]
Income Taxes	10. INCOME TAXES Due to the Company’s history of losses and uncertainty of future taxable income, a valuation allowance sufficient to fully offset net operating losses and other deferred tax assets has been established. The valuation allowance will be maintained until sufficient positive evidence exists to support a conclusion that a valuation allowance is not necessary. The Company’s effective tax rate for the nine months ended July 31, 2017 and 2016 differed from the expected U.S. federal statutory rate primarily due to the change in the valuation allowance. The issuance of Preferred Stock in connection with the Polarity acquisition will likely result in limitations on the utilization of the Company’s net operating loss carryforwards under IRS section 382.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
