Item 8.01 Other Events.

A new formulation of Acetadote (acetylcysteine) Injection was developed by Cumberland Pharmaceuticals Inc. (the "Company") as part of a Phase IV commitment by the Company in response to a request by the Food and Drug Administration
("FDA") to evaluate the reduction of ethylene diamine tetraacetic acid ("EDTA")
from the product's formulation. The new Acetadote formulation does not contain EDTA or any other chelating or stabilization agent and is free of preservatives. The new formulation was listed in the FDA Orange Book following its FDA approval in January 2011. In April 2012, the United States Patent and Trademark Office (the "USPTO") issued U.S. Patent number 8,148,356 (the "Acetadote Patent") which is assigned to the Company. The claims of the Acetadote Patent encompass the new Acetadote formulation and include composition of matter claims. Following its issuance, the Acetadote Patent was listed in the FDA Orange Book. The Acetadote Patent is scheduled to expire in May 2026 which time period includes a 270-day patent term adjustment granted by the USPTO. The Company also has additional patent applications relating to the uses of Acetadote which are pending with the USPTO.

Following the issuance of the Acetadote Patent, the Company received separate Paragraph IV certification notices from InnoPharma, Inc., Paddock Laboratories, LLC and Mylan Institutional LLC challenging the Acetadote Patent on the basis of non-infringement and/or invalidity. On May 17, 2012, the Company responded to the Paragraph IV certification notices by filing three separate lawsuits for infringement of the Acetadote Patent. The first lawsuit was filed against Mylan Institutional LLC and Mylan Inc. in the United States District Court for the Northern District of Illinois, Eastern Division. The second lawsuit was filed against InnoPharma, Inc. in the United States District Court for the District of Delaware. The third lawsuit was also filed in the United States District Court for the District of Delaware against Paddock Laboratories, LLC. On May 20, 2012, the Company received a fourth Paragraph IV certification notice from Sagent Agila LLC challenging the Acetadote Patent. On June 26, 2012, the Company filed a lawsuit for infringement of the Acetadote Patent against Sagent Agila LLC and Sagent Pharmaceuticals, Inc. in the United States District Court for the District of Delaware. On July 9, 2012, the Company received a Paragraph IV certification notice from Perrigo Company. On August 9, 2012, the Company filed a lawsuit for infringement of the Acetadote Patent against Perrigo Company in the United States District Court for the Northern District of Illinois, Eastern Division.

On November 12, 2012, the Company entered into a Settlement Agreement (the "Settlement Agreement") with Paddock and Perrigo to resolve the challenges and the pending litigation between the Company and each of Paddock and Perrigo involving the Acetadote Patent. Under the Settlement Agreement, Paddock and Perrigo admit that the Acetadote Patent is valid and enforceable and that any Paddock or Perrigo generic Acetadote product (with or without EDTA) would infringe upon the Acetadote Patent. In addition Paddock and Perrigo will not challenge the validity, enforceability, ownership or patentability of the Acetadote Patent through its expiration currently scheduled for May 2026. On November 12, 2012, in connection with the execution of the Settlement Agreement, the Company entered into a License and Supply Agreement with Paddock and Perrigo (the "License and Supply Agreement"). Under the terms of the License and Supply Agreement, if a third party receives final approval from the FDA for an ANDA to sell a generic Acetadote product and such third party has made such generic version available for purchase in commercial quantities in the United States, the Company will supply Perrigo with an authorized generic version of the Company's Acetadote product (the "Authorized Generic").

By statute, where the Paragraph IV certification is to a patent timely listed before an Abbreviated New Drug Application ("ANDA") is filed, a company has 45 days to institute a patent infringement lawsuit during which period the FDA may not approve another application. In addition, such a lawsuit for patent infringement filed within such 45-day period may stay, or bar, the FDA from approving another product application for two and a half years or until a district court decision that is adverse to the asserted patents, whichever is earlier. On May 18, 2012, the Company requested the aforementioned bar or stay in connection with the filing of the three lawsuits on May 17, 2012. The aforementioned bar or stay may or may not be available to the Company with respect to the remaining lawsuits.

On May 18, 2012, the Company also submitted a Citizen Petition to the FDA requesting that the FDA refrain from approving any applications for acetylcysteine injection that contain EDTA, based in part on the FDA's request that Cumberland evaluate the reduction or removal of EDTA from its original Acetadote formulation. On November 7, 2012, the FDA responded to the Citizen Petition denying the Company's request and stating that ANDAs referencing Acedadote that contain EDTA may be accepted and approved provided they meet all applicable requirements. The Company believes this response contradicts the FDA's request to evaluate the reduction or removal of EDTA. On November 8, 2012, the Company learned that the FDA approved the ANDA referencing Acetadote filed by InnoPharma, Inc. On November 13, 2012, the Company brought suit against the FDA in the United States District Court for the District of Columbia alleging that the FDA's denial of Cumberland's Citizen Petition and acceptance for review and approval of any InnoPharma product containing EDTA was arbitrary and in violation of law.

On November 5, 2012, the Company received a Notice of Allowance from the United States Patent and Trademark Office for a second patent relating to its new formulation of Acetadote. The new patent will include claims regarding the use of the 200 mg/ml Acetadote formulation to treat patients with acetaminophen overdose and will expire in August 2025.

The Company intends to continue to vigorously defend and protect its Acetadote product and related intellectual property rights.
