Is there a fee for rectifying obvious mistakes in a PCT application?
Generally, there is no fee for rectifying obvious mistakes in a PCT application. According to MPEP 1836:
“Any such rectification is free of charge.”
However, it’s important to note that while the rectification itself is free, there may be a fee associated with publishing a refused request for rectification. The MPEP states:
“Where the competent authority refuses to authorize a rectification under Rule 91.1, the International Bureau shall, upon request submitted to it by the applicant within two months from the date of the refusal, and subject to the payment of a special fee whose amount shall be fixed in the Administrative Instructions, publish the request for rectification, the reasons for refusal by the authority and any further brief comments that may be submitted by the applicant, if possible together with the international application.”
Therefore, while rectification itself is free, applicants should be aware that there may be costs associated with challenging a refusal to authorize a rectification.
