1212.6 Space 6: Date and Nation of First Commercial Exploitation
If the mask work has been commercially exploited, then the applicant must provide the complete date of first commercial exploitation in space 6. If the applicant has left space 6 blank, the registration specialist may communicate with the applicant to determine whether the mask work has been commercially exploited and will amend and annotate space 6, as appropriate, which will delay the examination of the application.
As discussed in Section 1205.2, a claim received more than two years from the date of first commercial exploitation is ineligible for registration. If, however, the two-year period ends on a day on which the U.S. Copyright Office does not receive mail (e.g., a Sunday or government holiday), the two-year period is extended to the next business day.
