Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation and Consolidation

The accompanying consolidated financial statements include the accounts of CBLI and its subsidiaries, BioLab 612, Incuron and Panacela, collectively referred to herein as the “Company.” All significant intercompany balances and transactions have been eliminated in consolidation.

The unaudited consolidated financial statements included herein have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the SEC, as amended.

In the opinion of the Company’s management, any adjustments contained in the accompanying unaudited consolidated financial statements are of a normal recurring nature, and are necessary to present fairly the financial position of the Company as of June 30, 2013, along with its results of operations for the three and six month periods ended June 30, 2013 and 2012 and cash flows for the six month periods ended June 30, 2013 and 2012.  Interim results are not necessarily indicative of results that may be expected for any other interim period or for an entire year.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Of the $13.2 million and $25.7 million of cash and cash equivalents at June 30, 2013 and December 31, 2012, respectively, $4.4 million and $13.0 million, respectively, consisted of highly liquid investments with maturities of 90 days or less when purchased.  These investments consist of commercial paper, short-term debt securities, time deposits and investments in money market funds with commercial banks and financial institutions. As of June 30, 2013, $4.4 million of the Company's cash and cash equivalents was restricted to the use of its majority-owned subsidiaries, leaving $8.8 million available for general use.

Marketable Securities, Policy [Policy Text Block]

Short-Term Investments

The Company’s short-term investments are classified as held to maturity given the intent and ability to hold the investments to maturity. Accordingly, these investments are carried at amortized cost. Short-term investments classified as held-to-maturity consisted of certificates of deposit with maturity dates beyond three months and less than one year. As of June 30, 2013, all of the Company’s short-term investments were restricted to the use of its majority-owned subsidiaries.

Revenue Recognition, Policy [Policy Text Block]

Significant Customers and Accounts Receivable

Grant and contract revenue from the United States government accounted for 37.7% and 34.8% of total revenue for the three and six months ended June 30, 2013, respectively, and 100.0% of total revenue for both the three and six months ended June 30, 2012.

Grant and contract revenue received by subsidiaries from Russian government agencies accounted for 62.3% and 65.2% of total revenues for the three and six months ended June 30, 2013, respectively, and 0% for both the three and six months ended June 30, 2012.

Although the Company anticipates ongoing federal and Russian government contract and grant revenue, there is no guarantee that these revenue streams will continue in the future.

Accounts receivable consist of amounts due under reimbursement contracts with certain government and foreign entities. The Company extends unsecured credit to customers under normal trade agreements, which generally require payment within 30 days.

Management estimates an allowance for doubtful accounts that is based upon management's review of delinquent accounts and an assessment of the Company's historical evidence of collections. There were no allowances for doubtful accounts as of June 30, 2013 and December 31, 2012, as the collection history from the Company’s customers indicated that collection was probable.

Intangible Assets, Finite-Lived, Policy [Policy Text Block]

Intellectual Property

Costs related to filing and pursuing patent applications are recognized as general and administrative expenses (“G&A expenses”) as incurred, since the recoverability of such expenditures is uncertain. Upon marketability approval by the U.S. Food and Drug Administration (“FDA”) or a respective foreign governing body, such costs will be capitalized and depreciated over the expected life of the related patent.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Accounting for Stock-Based Compensation

The 2006 Equity Incentive Plan, as amended (the “Plan”), authorizes CBLI to grant (i) options to purchase common stock, (ii) restricted or unrestricted stock units, and (iii) stock appreciation rights, so long as the exercise or grant price of each are at least equal to the fair market value of the stock on the date of grant. As of June 30, 2013, an aggregate of 10.0 million shares of common stock were authorized for issuance under the Plan, of which a total of approximately 2.1 million shares of common stock remained available for future awards. A single participant cannot be awarded more than 400,000 shares annually. Awards granted under the Plan have a contractual life of no more than 10 years. The terms and conditions of equity awards (such as price, vesting schedule, term and number of shares) under the Plan are specified in an award document, and approved by the Company’s compensation committee.

In June 2013 the Company’s stockholders approved the 2013 Employee Stock Purchase Plan (“ESPP”) which provides a means by which eligible employees of the Company and certain designated related corporations may be given an opportunity to purchase shares of Common Stock. As of June 30, 2013, there are 2,100,000 shares of Common Stock reserved for purchase under the ESPP. The number of shares reserved for purchase under the ESPP increases on January 1 of each calendar year by the lesser of (i) 10% of the total number of shares of Common Stock outstanding on December 31st of the preceding year, or (ii) 200,000 shares of Common Stock. The ESPP allows employees to use up to 15% of their compensation to purchase shares of Common Stock at an amount equal to 85% of the fair market value of the Company’s Common Stock on the offering date or the purchase date, whichever is less.

The Company utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted where the vesting period is based on length of service or performance, while a Monte Carlo simulation model is used for estimating the fair value of stock options with market-based vesting conditions. Set forth below are the assumptions used in valuing the stock options granted and a discussion of the Company’s methodology for developing each of the assumptions used: 

	For the six months ended June 30,
	2013			2012
Risk-free interest rate	0.02	-	1.92%	0.75	-	1.49%
Expected dividend yield	0%			0%
Expected life (Years)	5	-	7.3	5	-	6
Expected volatility	80.71	-	89.66%	86.58	-	92.24%

“Risk-free interest rate” means the range of U.S. Treasury rates with a term that most closely resembles the expected life of the option as of the date the option is granted.

“Expected dividend yield” means the Company does not pay regular dividends on its common stock and does not anticipate paying any dividends in the foreseeable future.

“Expected life” means the period of time that options granted are expected to remain outstanding, based wholly on the use of the simplified (safe harbor) method. The simplified method is used because the Company does not yet have adequate historical exercise information to estimate the expected life the options granted.

“Expected volatility” means a measure of the amount by which a financial variable, such as share price, has fluctuated (historical volatility) or is expected to fluctuate (implied volatility) during a period. Expected volatility is based on the Company’s historical volatility and incorporates the volatility of the common stock of comparable companies when the expected life of the option exceeds the Company’s trading history.

Income Tax, Policy [Policy Text Block]

Income Taxes

No income tax expense was recorded for the three and six months ended June 30, 2013 and 2012, as the Company does not expect to have taxable income for 2013 and did not have taxable income in 2012. A full valuation allowance has been recorded against the Company’s deferred tax asset.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) per Share

Basic net income (loss) per share of common stock excludes dilution for potential common stock issuances and is computed by dividing net income (loss) by the weighted average number of shares outstanding for the period. Diluted net income (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Diluted net loss per share is identical to basic net loss per share as potentially dilutive securities have been excluded from the calculation of diluted net loss per common share because the inclusion of such securities would be antidilutive.

The Company has excluded the following outstanding warrants and options from the calculation of diluted net loss per share because all such securities were antidilutive for the periods presented:

Commitments and Contingencies, Policy [Policy Text Block]

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business.  The Company accrues for liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated.  For all periods presented, the Company is not a party to any pending material litigation or other material legal proceedings.
