, patentees may have more limited access to post-grant proceedings at the PTAB within the USPTO since there are fewer judges within the PTAB. This may make it more difficult for us to challenge competitor patents in a cost-effective
manner and may instead require us to bring a more costly and lengthy patent litigation to challenge competitor patents.

Issued patents covering our products, services or technology could be found invalid or unenforceable if challenged.

The issuance of a patent is not conclusive as to its inventorship, scope,
validity or enforceability. Some of our patent rights may be challenged at a future point in time in opposition, derivation, re-examination,inter partes review, post-grant review. Any
successful third-party challenge to our patent rights in this or any other proceeding could result in the unenforceability or invalidity of such patent rights, which may lead to increased competition to our business. In addition, if the breadth or
strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop, manufacture or commercialize our current or future products,
services or technology.

We may not be aware of all third-party intellectual property rights potentially relating to our products or
technology. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until approximately 18 months after filing
or, in some cases, not until such patent applications issue as patents. We might not have been the first to make the inventions covered by each of our pending patent applications and we might not have been the first to file patent applications for
these inventions. To determine the priority of our inventions, we may participate in interference proceedings, derivation proceedings or other post-grant proceedings declared by the USPTO that could result in substantial cost to us. The outcome of
such proceedings is uncertain. No assurance can be given that other patent applications will not have priority over our patent applications. In addition, changes to the patent laws of the United States allow for various post-grant opposition
proceedings that have not been extensively tested, and their outcome is therefore uncertain. If third parties bring actions against our patent rights, we could experience significant costs and management distraction.

In patent litigation in the United States or abroad, defendant counterclaims alleging invalidity or unenforceability of plaintiff’s patents are common. Grounds for
a validity challenge could be an
