We own numerous patents, trademarks, trade secrets, copyrights and other intellectual property and hold licenses to intellectual property owned by others, which in the aggregate are important to our business. We rely on a combination of patent, trademark, copyright and trade secret laws in our core geographic markets and other jurisdictions to protect the innovations, brands, proprietary trade secrets and know-how related to certain aspects of our business. Certain of our intellectual property rights, such as patents, are time-limited, and the technology underlying our patents can be used by any third party, including competitors, once the applicable patent terms expire.
We seek to protect our confidential proprietary information, in part, by entering into confidentiality and invention assignment agreements with our employees, consultants, contractors, suppliers and others. While these agreements are designed to protect our proprietary information, we cannot be certain that such agreements have been entered into with all relevant parties, and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. We also seek to preserve the integrity and confidentiality of our proprietary information by maintaining physical security of our premises and physical and electronic security of our information technology systems, but it is possible that these security measures could be breached. If these physical and electronic security measures fail, or if we are otherwise unable to prevent disclosure to third parties of our material proprietary and confidential know-how and trade secrets, our ability to establish or maintain a competitive advantage in our markets may be adversely affected.
We selectively and strategically pursue patent, trademark and trade secret protection in our core geographic markets, but our strategy has been to not perfect certain patent and trademark rights in some countries. For example, we focus primarily on securing patent protection in those countries where the majority of our golf ball and golf club industry production takes place. Accordingly, we may not be able to prevent others, including competitors, from practicing our patented inventions, including by manufacturing and selling competing products, in those countries where we have not obtained patent protection. Further, the laws and law enforcement practices of some foreign countries do not protect proprietary rights and intellectual property rights to the same extent or in the same manner as the laws of the United States, and in some foreign countries third-party manufacturers may be able to manufacture and sell imitation products and diminish the value of our brands as well as infringe our rights, despite our efforts to prevent such activity.
The golf ball and golf club industries, in particular, have been characterized by widespread imitation of popular ball and club designs. We have an active program of monitoring, investigating and enforcing our proprietary rights against companies and individuals who market or manufacture counterfeits and "knockoff" products. We assert our rights against infringers of our patents, trademarks, trade dress and copyrights. However, these efforts may be expensive, time-consuming, divert management's attention, and ultimately may not be successful in reducing sales of golf products by these infringers. The failure to prevent or limit such infringers or imitators could adversely affect our reputation and sales. Additionally, other golf ball and golf club manufacturers may be able to produce successful golf balls or golf clubs which imitate our designs without infringing any of our patents, trademarks, trade dress or copyrights, which could limit our ability to maintain a competitive advantage in our marketplace.
If we fail to obtain enforceable patents, trademarks and trade secrets, fail to maintain our existing patent, trademark and trade secret rights, or fail to prevent substantial unauthorized use of our patents, trademarks and trade secrets, we risk the loss of our intellectual property rights and competitive advantages we have developed, which may result in lost sales. Accordingly, we devote substantial resources to the establishment and protection of our patents, trademarks and trade secrets or know-how, and we continuously evaluate the utility of our existing intellectual property and the new registration of additional trademarks and patents, as appropriate. However, we cannot guarantee that we will have adequate resources to continue to effectively establish, maintain and enforce our intellectual property rights. We also cannot guarantee that any of our pending applications will be approved by the applicable governmental authorities. Moreover, even if the applications will be registered during the registration process, third parties may seek to oppose, limit, or otherwise challenge these applications or registrations.
