Details
Do not use this form if you want the international application to be treated as an application under the Act, in accordance with section 89(3) or (5), when it, or the designation of the United Kingdom in it, has been deemed withdrawn, or when it has been refused a filing date under the Treaty. In these circumstances you should apply in writing to the office within 2 months of the notification mentioned in PCT Rule 51. You should include a statement of the facts on which you rely together with the fee which is payable (see rule 71). Within the same period of 2 months you should ask the International Bureau to send copies of the documents on file to the office (PCT Article 25.1).
A fee is payable upon entering the national phase. For details of that fee, and fees due in respect of requests made under part 6 and parts 8(a) and (b) above, and ways to pay, please contact the Office.
All Intellectual Property Office fee bearing forms should be filed with the appropriate fee.
