Can the International Preliminary Examining Authority require a sequence listing after filing?
Yes, the International Preliminary Examining Authority (IPEA) has the power to require a sequence listing after the initial filing of a PCT application. MPEP 1877 states:
“the International Preliminary Examining Authority may invite the applicant to furnish such a sequence listing complying with the standard provided for in the Administrative Instructions and pay a late furnishing fee.”
This provision allows the IPEA to request a compliant sequence listing if they determine it’s necessary for the examination process, even if it wasn’t included in the original application. The applicant may also be required to pay a late furnishing fee for this submission.
