The Company's commercial success depends in part on its ability to develop, manufacture, market and sell its products and use its proprietary technology without infringing the patent rights of third parties. Numerous third-party U.S. and non-U.S. issued patents and pending applications exist in the area of the Company's products. The Company may in the future pursue available proceedings in the U.S. and foreign patent offices to challenge the validity of patents and patent applications. In addition, or alternatively, the Company may consider whether to seek to negotiate a license of rights to technology covered by one or more of such patents and patent applications. If any patents or patent applications cover the Company's products or technologies, the Company may not be free to manufacture or market its products as planned, absent such a license, which may not be available to the Company on commercially reasonable terms, or at all.
It is also possible that the Company has failed to identify relevant third-party patents or applications. For example, some applications may be held under government secrecy and US patent applications that will not be filed outside the United States remain confidential unless and until patents issue. Moreover, it is difficult for industry participants, including the Company, to identify all third-party patent rights that may be relevant to its product candidates and technologies because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. The Company may fail to identify relevant patents or patent applications or may identify pending patent applications of potential interest but incorrectly predict the likelihood that such patents may issue with claims of relevance to its technology. In addition, the Company may be unaware of one or more issued patents that would be infringed by the manufacture, sale or use of a current or future products, or the Company may incorrectly conclude that a third-party patent is invalid, unenforceable or not infringed by its activities. Additionally, pending patent applications that have been published can, subject to specified limitations, be later amended in a manner that could cover the Company's technologies, its products or the use of its products.
There have been many lawsuits and other proceedings filed by third parties involving patent and other intellectual property rights, including patent infringement lawsuits, interferences, oppositions, and reexamination, post-grant review and equivalent proceedings before the USPTO and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which the Company is developing products or has existing products. As the industries the Company is involved in expand and more patents are issued, the risk increases that its product candidates may be subject to claims of infringement of the patent rights of third parties.
Parties making claims against the Company may obtain injunctive or other equitable relief, which could effectively block its ability to further develop and commercialize the Company's products. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from the Company's business. In the event of a successful claim of infringement against the Company, the Company may have to pay substantial damages, including treble damages and attorneys' fees for willful infringement, pay royalties, redesign its infringing products or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure.
