Which situation does NOT permit an extension of time to respond to an Office Action?

The situation that does not permit an extension of time to respond to an Office Action involves filing for a new continuation application. In the context of the Manual of Patent Examining Procedure (MPEP), a continuation application is a type of application that allows an applicant to pursue additional claims that may be related to an earlier application. When a continuation application is filed, it is treated as a new application that is independent and does not relate to responding to the USPTO's Office Action.

Generally, there are specific time frames set by the USPTO for filing responses to Office Actions, and these time frames are stringent. Thus, filing for a new application does not inherently provide grounds for an extension of time associated with an ongoing Office Action response, which must be addressed within the stipulated timeline. This distinguishes it from other scenarios where extensions may be granted, such as responses to appeals or during interactions with the examiner regarding amendments.
