 in the pharmaceutical and biotechnology industries, including patent infringement lawsuits and interference, derivation, inter partes review and post-grant review proceedings before the USPTO, as well as oppositions and similar processes in foreign jurisdictions. Litigation or other proceedings relating to intellectual property rights are often very complex in nature, may be very expensive and time-consuming, may divert our management’s attention from our core business, and may result in unfavorable results that could limit our ability to prevent third parties from competing with our current and future Product Candidates.

One or more third parties may challenge our current or future patents, which could result in the invalidation of, or render unenforceable, some or all of the relevant patent claims, or a finding of non-infringement. For example, if a third party files an ANDA for a generic copy of one of our products, and relies in whole or in part on studies conducted by or for us, the third party will be required to certify to the FDA that either: (1) there is no patent information listed in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” commonly known as the “Orange Book”, with respect to our NDA for the applicable approved product candidate; (2) the patents listed in the Orange Book have expired; (3) the listed patents have not expired, but will expire on a particular date and approval is sought after patent expiration; or (4) the listed patents are invalid or will not be infringed by the manufacture, use or sale of the third party’s generic drug. A certification that the new drug will not infringe the Orange Book-listed patents for the applicable approved Product Candidate, or that such patents are invalid, is called a paragraph IV certification. If the third party submits a paragraph IV certification to the FDA, a notice of the paragraph IV certification must also be sent to us once the third party’s ANDA is accepted for filing by the FDA. We may then initiate a lawsuit to defend the patents identified in the notice. The filing of a patent infringement lawsuit within 45 days of receipt of the notice automatically prevents the FDA from approving the third party’s ANDA until the earliest of 30 months or the date on which the patent expires, the lawsuit is settled, or the court reaches a decision in the infringement lawsuit in favor of the third party. If we do not file a patent infringement lawsuit within the required 45-day period, the third party’s ANDA will not be subject to the 30-month stay of
