REFERENCE ONLY

This calendar only adds the selected number of months and shows weekend/federal-holiday adjustments. It does not determine your USPTO response deadline. Always confirm the period and filing date in the actual Office communication and current USPTO rules.

Calculation method & limits

The calendar adds the selected number of calendar months using the corresponding day of the month. If that reference date falls on a Saturday, Sunday, or listed D.C. federal holiday, the highlight moves to the next listed business day.

This simple calendar does not evaluate case-specific rules, extension eligibility, Advisory Action timing, non-extendable periods, or future unscheduled USPTO closures.

Reference basis reviewed for this prototype: MPEP §§ 710.01(a), 710.02(b), 710.05; 37 C.F.R. §§ 1.7, 1.136.
