Yes, there are several exceptions to the standard extension of time rules for patent applications. According to MPEP 710.02(e), some notable exceptions include:

1. Design Applications: An extension of time in a design application operates differently than in a utility application. Unlike a utility application, an extension of time in a design application extends both the shortened statutory period and maximum statutory period for reply.
2. Reexamination Proceedings: In reexamination proceedings, extensions of time are limited to a maximum of 2 months from the time period set in the Office action.
3. Interference Proceedings: In interference proceedings, there are no automatic extensions of time for taking action. Extensions of time may be granted only upon a showing of good cause.

Additionally, some actions have specific rules regarding extensions, such as:

• Responding to a notice of allowance
• Filing an appeal brief
• Replying to a final Office action

It’s crucial to consult the specific MPEP sections or USPTO petition guidelines related to your particular situation, as the rules can vary depending on the type of application and the nature of the required action.
