The USPTO recently proposed requiring third-party requesters for ex parte reexamination to identify themselves and any real parties in interest to the Office, while allowing that information to remain confidential from the public. In comments submitted to the USPTO, C4IP supported the proposal’s goal of helping the Office better enforce statutory limits on repetitive patent challenges, while urging additional clarity on how requester confidentiality would be protected in practice. Below, we clarify three key points about the proposal:
| Claim: Requiring requesters to identify themselves to the USPTO would eliminate anonymous ex parte reexamination requests. |
| In Reality: The proposal would allow requester identities and information about real parties in interest to remain confidential from the public and patent owner, preserving confidentiality that has long been an important feature of ex parte reexamination. The key question is how the USPTO will safeguard that information in practice, including in contexts such as Freedom of Information Act (FOIA) requests or related proceedings. |
| Claim: The USPTO does not need this information to prevent improper repeat challenges. |
| In Reality: Whether a request is barred by statutory estoppel can depend on who is behind it, and the requester and USPTO may reach different conclusions about whether the law permits a proceeding. Providing the Office access to information about real parties in interest can help it identify barred requests before patent owners are forced to defend against another challenge and agency resources are spent on a proceeding that should not have been initiated. |
| Claim: Preventing repetitive patent challenges requires limiting access to ex parte reexamination. |
| In Reality: Ex parte reexamination remains an important mechanism for reconsidering patent claims that may not have been properly issued. The goal is not to restrict legitimate use of the process, but to ensure the USPTO has the information necessary to distinguish permissible requests from those barred by statute. |
