Regulations under the PCT
Rule 37
Missing or Defective Title
If the international application does not contain a title and the receiving Office has notified the International Searching Authority that it has invited the applicant to correct such defect, the International Searching Authority shall proceed with the international search unless and until it receives notification that the said application is considered withdrawn.
If the international application does not contain a title and the International Searching Authority has not received a notification from the receiving Office to the effect that the applicant has been invited to furnish a title, or if the said Authority finds that the title does not comply with Rule 4.3, it shall itself establish a title. Such title shall be established in the language in which the international application is to be published or, if a translation into another language was transmitted under Rule 23.1(b) and the International Searching Authority so wishes, in the language of that translation.
