How does the USPTO handle time zone differences in statutory period calculations?
The USPTO handles time zone differences in statutory period calculations by using a standardized approach based on Eastern Time. Here’s what you need to know:
- All deadlines are calculated based on Eastern Time, regardless of the applicant’s location.
- The statutory period ends at midnight Eastern Time on the last day of the period.
- Submissions are considered timely if received by 11:59:59 PM Eastern Time on the due date.
As stated in MPEP 710.01(a):
“In computing the legal or statutory period, the day of the act, event, or default from which the designated period of time begins to run is not included.”
This means that regardless of where an applicant is located, they must ensure their submissions are received by the USPTO before the Eastern Time deadline to be considered timely. It’s advisable for applicants in different time zones to factor in this time difference when planning their submissions.
