Does filing a petition stop the time period for replying to a 37 CFR 1.105 requirement?

No, filing a petition does not stop the time period for replying to a 37 CFR 1.105 requirement. The MPEP clearly states:

“However, a petition is not a reply to a 37 CFR 1.105 requirement. The time period for the applicant to reply to the 37 CFR 1.105 requirement continues to run, even where a petition has been submitted.”

This means that applicants must still respond to the requirement within the given time frame, regardless of whether they have filed a petition.
