We have licensed one patent family covering the composition of matter for NXP900, which has been granted in the U.S., EU, Japan, China and is pending in the United Kingdom and Canada. The statutory expiration for patents in this patent family is April 2036, without considering any possible patent term extension.
If the scope of our patent protection, whether now or in the future, with respect to NXP800, NXP900 or our future product candidates and technology is not sufficiently broad, we will be unable to prevent others from using our technology or from developing or commercializing technology and products similar or identical to ours or other competing products and technologies. Any failure to obtain or maintain patent protection, through our own patents or through in-licensing, with respect to NXP800, NXP900 and our future product candidates would have a material adverse effect on our business, financial condition, results of operations and prospects.
Even if they are unchallenged, our patent applications, if issued, and any patents we may own or in-license now or in the future, may not provide us with any meaningful protection or prevent competitors from designing around our patent claims to circumvent any patents we may own or in-license in the future by developing similar or alternative technologies or therapeutics in a non-infringing manner. If the patent protection provided by our patent applications or any patents we may pursue with respect to our current or future product candidates is not sufficiently broad to impede competition, our ability to successfully commercialize our current or future product candidates could be negatively affected, which would harm our business.
Additionally, we cannot be certain that the claims in our patent applications covering composition of matter (or other related aspects) of our current or future product candidates or technology will be considered patentable by the USPTO, or by patent offices in foreign countries, or that the claims in any issued patents we may own or in-license in the future will be considered patentable by courts in the United States or foreign countries.
The issuance of a patent does not foreclose challenges to its inventorship, scope, validity or enforceability. Therefore, our owned and in-licensed patents may be challenged in the courts or patent offices in the United States and elsewhere. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated, or held unenforceable, in whole or in part. Successful patent challenges could limit our ability to stop others from using or commercializing similar or identical technology and products or limit the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our owned and in-licensed patents may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
Moreover, patents or patent applications owned or filed by us, or by our licensors or other collaborators, may be challenged or narrowed by third-party pre-issuance submissions of prior art to the USPTO, or by opposition, derivation, reexamination, inter parties review, post-grant review or interference proceedings. An adverse determination in any such submission, Patent Trial and Appeal Board trial, proceeding or litigation could reduce the scope of, render unenforceable, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.
If we fail to comply with our obligations in our current license agreements, or in any future agreements under which we may license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our current or future licensors, we could lose license rights that are important to our business.
We are currently party to a license which grants us certain intellectual property rights relating to our lead product candidate, NXP800, as well as other related compounds, and to a license which grants us certain intellectual property rights relating to our second drug candidate, NXP900, as well as other compounds that inhibit the SRC and YES1 kinases. These agreements impose numerous obligations on us to maintain our licensing rights, including development, diligence, payment, commercialization, funding, milestone, royalty, sublicensing, insurance, patent prosecution, enforcement and other obligations. In spite of our efforts, our licensor might conclude that we have materially breached our license
