Can multiple interim extensions be granted for a single patent?

Yes, multiple interim extensions can be granted for a single patent. MPEP 2755.01 states: “If a determination is made that the patent is eligible for extension, an interim extension is granted for a period of up to one year. Additional interim extensions may be granted if required to extend the patent term until a final determination on the application for extension can be made.” This provision allows for continued protection of the patent while the extension application is being processed, especially in cases where regulatory approval takes longer than anticipated.
