curtail the use of these materials and interrupt our business operations. We do not currently maintain hazardous materials insurance coverage. If we are subject to any liability as a result of our third-party manufacturers’ activities involving hazardous materials, our business and financial condition may be adversely affected. In the future we may seek to establish longer term third-party manufacturing arrangements, pursuant to which we would seek to obtain contractual indemnification protection from such third-party manufacturers potentially limiting this liability exposure.
 
Our business and operations would suffer in the event of system failures.
 
Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from completed or ongoing clinical trials for Contrave or Excalia could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of our product candidates could be delayed.
 
Risks Related to Intellectual Property
 
The issued patent rights that we have in-licensed covering Contrave and Excalia are limited to the United States, and our market opportunity for these product candidates may be limited by the lack of patent protection in other territories.
 
Contrave is currently protected by U.S. patent number 5,512,593 issued in April 1996 and U.S. patent number 5,817,665 issued in October 1998, which we have licensed on an exclusive basis from Dr. Lee Dante. Provided maintenance fees are paid, U.S. patent number 5,512,593 is expected to expire in April 2013 and U.S. patent 5,817,665 is expected to expire in March 2013. These patents do not protect our Contrave product candidate outside of the United States. The Dante patents cover compositions of certain specified opioid antagonists (including naltrexone) combined with certain specified antidepressants (including bupropion).
 
In addition to the Dante patents that are licensed to us, we own a U.S. patent application and a related continuation patent application, referred to by us as the Weber/Cowley patent applications, which are the subject of an agreement with Oregon Health & Science University, or OHSU. The claims currently pending in the Weber/Cowley patent applications are directed to the current composition of our Contrave product candidate and methods for using that composition to effect weight loss. The Weber/Cowley patent applications have not yet issued and we cannot provide assurance that they will issue on a timely basis or at all. We have filed a number of international counterparts to the Weber/Cowley patent applications in foreign countries and also cannot provide assurance that they will issue on a timely basis or at all.
 
Both pending Weber/Cowley patent applications have been initially rejected by the U.S. Patent and Trademark Office, or PTO, one on the basis that a prior Dante patent anticipated the composition claims and the other primarily on the basis that the claimed methods of treatment were obvious. Although we believe that we have sufficient arguments, and can amend our applications in such a way as to overcome these initial rejections of claims, there can be no assurance that these rejections and any future rejections will ultimately be overcome or that any claims that may issue will be sufficiently broad to protect our Contrave product in the United States. If these U.S. patent applications and their international counterparts ultimately issue, we expect to have protection extended through 2024. However, we cannot be certain that the scope of any issued U.S. or foreign patent will be consistent with the currently pending claims, as there is a significant likelihood that the scope of the currently pending claims will be modified. A European counterpart application to the Weber/Cowley patents applications is currently pending in the European Patent Office, or EPO. However, there is no assurance that the claims in this application, or any other claims, will issue in their currently pending form or at all.
