How are canceled claims handled in the ex parte reexamination certificate?

Canceled claims are handled specifically in the ex parte reexamination certificate. The MPEP 2287 states:

“Claims which were canceled will be replaced by a statement in the reexamination certificate that the claims were canceled.”

This means that rather than simply omitting the canceled claims, the certificate explicitly acknowledges their cancellation. This approach ensures a clear record of the changes made during the reexamination process.
