 of the patent or patent application, resulting in a partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market with similar or identical products or technology, which could have a material adverse effect on our business, financial condition, results of operations and prospects. Patent terms may be inadequate to protect our competitive position on products or product candidates for an adequate amount of time. Patents have a limited lifespan. In most countries, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest national or international (i.e., PCT) filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. After patents expire, we may be open to competition with respect to products that were covered by the expired patents. 48 If we do not obtain patent term extension and/or data exclusivity for any product candidates we decide to develop as drug product candidates, our business may be materially harmed. Depending upon the timing, duration and specifics of any FDA marketing approval of any product candidates we decide to develop as product candidates, one or more of the U.S. patents we may obtain may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act, also known as the Hatch -WaxmanAct. The Hatch -WaxmanAct permits a patent term extension of up to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. Similar extensions as compensation for patent term lost during regulatory review processes are also available in certain foreign countries and territories, such as in Europe under a Supplementary Protection Certificate. However, we may not be granted an extension in the United States and/or foreign countries and territories because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. We may not be eligible for patent term extension, or PTE, as it is only available in the U.S. if any component of a product candidate
