The value of our OLED technologies and materials is dependent on our ability to secure and maintain appropriate patent and other intellectual property rights protection. Although we own or license many patents respecting our OLED technologies and materials that have already been issued, there can be no assurance that additional patents applied for will be obtained, or that any of these patents, once issued, will afford commercially significant protection for our OLED technologies and materials, or will be found valid if challenged. Also, there is no assurance that we will be successful in defending the validity of our current or future patents in pending and future patent oppositions, invalidation trials, interferences, reexaminations, reissues, or other administrative or court proceedings. Moreover, we have not obtained patent protection for some of our OLED technologies and materials in all foreign countries in which OLED products or materials might be manufactured or sold.
We believe that the strength of our current intellectual property position results primarily from the essential nature of our fundamental patents covering phosphorescent OLED devices and certain materials utilized in these devices. Certain of our existing fundamental phosphorescent OLED patents expired in the United States in 2017 and 2019; and expired in other countries of the world in 2018 and 2020. While we hold a wide range of additional patents and patent applications relating to our commercial OLED materials and technologies whose expiration dates extend (and in the case of patent applications, will extend) beyond 2024, many of which are also of importance in the OLED industry, none may be of an equally essential nature as our original fundamental patents, and therefore our competitive position may be less certain as a result of the expiration of these patents.
We have more than 6,500 issued and pending patents relating to our OLED technologies. There is no assurance that these patents and applications will not be challenged prior to their respective expirations in any of the jurisdictions in which they are utilized, or that if challenged, we will be able to secure sufficient breadth of protection, and monetary and injunctive relief for the violation of our rights to make up for the business harm resulting from such activities. Moreover, there can be no assurance that competitors will not develop or produce competing PHOLED material designs that may be outside of our existing patents. There may also be fundamental new advancements in the field of OLED technology that could enable the commercial use of older and unpatented PHOLED materials or the adoption of new OLED materials that do not require the utilization of our proprietary PHOLED materials to achieve superior performance characteristics.
We may become engaged in litigation to protect or enforce our patent and other intellectual property rights, or in International Trade Commission proceedings to abate the importation of goods that would compete unfairly with those of our licensees. In addition, we are participating in or have participated in, and in the future will likely have to participate in, interference, reissue, or reexamination proceedings before the U.S. Patent and Trademark Office, and opposition, nullity or other proceedings before foreign patent offices, with respect to some of our patents or patent applications. All of these actions place our patents and other intellectual property rights at risk and may result in substantial costs to us as well as a diversion of management attention from our business and operations. Moreover, if successful, these actions could result in the loss of patent or other intellectual property rights protection for the key OLED technologies and materials on which our business depends.
We rely, in part, on several non-patented proprietary technologies to operate our business. Others may independently develop the same or similar technologies or otherwise obtain access to our unpatented technologies. Furthermore, these parties may obtain patent protection for such technology, inhibiting or preventing us from practicing the technology. To protect our trade secrets, know-how and other non-patented proprietary information, we require employees, consultants, financial advisors and strategic partners to enter into confidentiality agreements. These agreements may not ultimately provide meaningful protection for our trade secrets, know-how or other non-patented proprietary information. In particular, we may not be able to fully or adequately protect our proprietary information as we conduct discussions with potential strategic partners.
Additionally, although we take many measures and implement safeguards to prevent unauthorized use, including by theft and misuse, of our intellectual property and proprietary information, third parties may attempt to obtain, copy, reverse-engineer, use or disclose, illegally or otherwise, such intellectual property and proprietary information. We also may face attempts by others to gain unauthorized access through the Internet to our information technology systems or to our intellectual property, which might be the result of industrial or other espionage or actions by hackers seeking to harm our company or its products. If we are unable to protect the proprietary nature of our intellectual property and proprietary information, it will harm our business.
