 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. Furthermore, if third parties bring these proceedings against our patents (whether owned by us or in-licensed from Ligand or another third party), we could experience significant costs and management distraction.

Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing Ligand’s ability to protect our products, platform and technology on which we rely.

Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents, and may diminish our ability to protect our inventions, obtain, maintain, enforce and protect our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of our future owned and licensed patents. Depending on future actions by the United States Congress, the United States courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our or our license partners’ ability to obtain new patents and patents that we or our license partners might obtain in the future. For example, on June 1, 2023, the European Union Patent Package (“EU Patent Package”) regulations were implemented with the goal of providing a single pan-European Unitary Patent and a new European Unified Patent Court (“UPC”) for litigation involving European patents. As a result, all European patents, including those issued prior to ratification of the EU Patent Package, now by default automatically fall under the jurisdiction of the UPC. It is uncertain how the UPC will impact granted European patents in the biotechnology and pharmaceutical industries. Our or our license partners’ European patent applications, if issued, could be challenged in the UPC. During the first seven years of the UPC’s existence, the UPC legislation allows a patent owner to opt our European patents out of the jurisdiction of the UPC. We or our license partners may decide to opt out future European patents from the UPC, but doing so may preclude we or our license partners from realizing the benefits of the UPC. Moreover, if we or our license partners do not meet all of the formalities and requirements for opt-out under the UPC, our or our license partners’ future European patents could remain under the jurisdiction of the UPC. The UPC will provide our and our license partners’ competitors with a new forum to centrally revoke
