could be harmed if we fail to secure long-term relationships with entities that will supply the required components for our SureSource products.
We depend on our intellectual property, and our failure to protect that intellectual property could adversely affect our future growth and success.
Failure to protect our existing intellectual property rights may result in the loss of our exclusivity or the right to use our technologies. If we do not adequately ensure our freedom to use certain technology, we may have to pay others for rights to use their intellectual property, pay damages for infringement or misappropriation, or be enjoined from using such intellectual property. We rely on patent, trade secret, trademark and copyright law to protect our intellectual property.
We have licensed our carbonate fuel cell manufacturing intellectual property to POSCO Energy Co., Ltd. (“POSCO Energy”) through a series of technology transfer agreements and have provided POSCO Energy with the exclusive right to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in Asia. In addition, effective as of June 11, 2019, we entered into a License Agreement (the “EMRE License Agreement”) with ExxonMobil Research and Engineering Company (“EMRE”), pursuant to which we agreed, subject to the terms of the EMRE License Agreement, to grant EMRE and its affiliates a non-exclusive, worldwide, fully paid, perpetual, irrevocable, non-transferrable license and right to use our patents, data, know-how, improvements, equipment designs, methods, processes and the like to the extent it is useful to research, develop, and commercially exploit carbonate fuel cells in applications in which the fuel cells concentrate carbon dioxide from industrial and power sources and for any other purpose attendant thereto or associated therewith. Such right and license is sublicensable to third parties performing work for or with EMRE or its affiliates, but shall not otherwise be sublicensable. We depend on POSCO Energy and EMRE to also protect our intellectual property rights as licensed.
As of July 31, 2019, we, excluding our subsidiaries, had 95 U.S. patents and 154 patents in other jurisdictions covering our fuel cell technology (in certain cases covering the same technology in multiple jurisdictions), with patents directed to various aspects of our SureSource technology, solid oxide fuel cell (“SOFC”) technology, PEM fuel cell technology and applications thereof. As of July 31, 2019, we also had 65 patent applications pending in the U.S. and 115 patent applications pending in other jurisdictions. Our U.S. patents will expire between 2019 and 2037, and the current average remaining life of our U.S. patents is approximately 8.7 years. Our subsidiary, Versa Power Systems, Ltd., as of July 31, 2019, had 33 U.S. patents and 95 international patents covering the SOFC technology (in certain cases covering the same technology in multiple jurisdictions), with an average remaining U.S. patent life of approximately 5.8 years. As of July 31, 2019, Versa Power Systems, Ltd. also had one pending U.S. patent application and nine patent applications pending in other jurisdictions. In addition, as of July 31, 2019, our subsidiary, FuelCell Energy Solutions, GmbH, had license rights to two U.S. patents and seven patents outside the U.S. for carbonate fuel cell technology licensed from Fraunhofer IKTS.
Some of our intellectual property is not covered by any patent or patent application and includes trade secrets and other know-how that is not able to be patented, particularly as it relates to our manufacturing processes and engineering design. In addition, some of our intellectual property includes technologies and processes that may be similar to the patented technologies and processes of third parties. If we are found to be infringing third-party patents, we do not know whether we will be able to obtain licenses to use such patents on acceptable terms, if at all. Our patent position is subject to complex factual and legal issues that may give rise to uncertainty as to the validity, scope, and enforceability of a particular patent.
We cannot assure you that any of the U.S. or international patents owned by us or other patents that third parties license to us will not be invalidated, circumvented, challenged, rendered unenforceable or licensed to others, or that any of our pending or future patent applications will be issued with the breadth of claim coverage sought by us, if issued at all. In addition, effective patent, trademark, copyright and trade secret protection may be unavailable, limited or not applied for in certain foreign countries.
We also seek to protect our proprietary intellectual property, including intellectual property that may not be patented or able to be patented, in part by confidentiality agreements and, if applicable, inventors’ rights agreements with our subcontractors, vendors, suppliers, consultants, strategic business associates and
