With regard to an international application for a patent of invention, the applicant may amend the application on his own initiative at the time when a request for examination is made, and within three months after the receipt of the notification of the Office that the application has entered into examination as to substance. Where the applicant wishes to amend the application, to correct defects indicated in the notification of opinions of the examination issued by the Office, such amendments shall be made within the time limit set by the Office.
CN.07 INSTRUMENT OF ASSIGNMENT
The applicant is presumed to have the right to file the international application and therefore no instrument of assignment is required if the international application is filed by an entity for an employee invention made by an inventor who is an employee of that entity. After the application is filed, an instrument of assignment is required for each change if there is any change in the person of the applicant.
CN.08 SPECIAL FEE IN CASE OF LACK OF UNITY OF INVENTION
PCT Art. 17(3)(b), PCT Art. 34(3)(c), CPR Rule 115
Where a part of the international application was not subjected to international search or preliminary examination because the international application did not comply with the requirement of unity of invention and the applicant did not pay the additional search or preliminary examination fee to the International Searching or Preliminary Examination Authority, the Office will decide whether the said finding as regards the application translated into the Chinese language was correct. If this is found to be the case, the Office will invite the applicant to pay a special fee within the time limit fixed in the notification of this decision. The amount of the said fee is indicated in Annex CN.I. Where the applicant does not pay the special fee, that part of the international application which was not subjected to international search or preliminary examination will be considered withdrawn.
CN.09 ANNUAL FEES
CPL Art. 43, CPR Rules 54, CPR Rules 98
The first annual fee must be paid within two months from the receipt of the notice from the Office of the grant of the patent.

If the annual fee is not paid or not paid in full, the Office will invite the applicant to pay it within six months from the expiration of the time limit due, with a surcharge. Where the annual fee is not paid within the prescribed time limit, the patent shall be deemed lapsed from the expiration of the time limit within which the annual fee should have been paid. The amounts of the annual fees are indicated in Annex CN.I.
CN.10 REVIEW UNDER ARTICLE 25 OF THE PCT
PCT Art. 25, PCT Rule 51, CPR Rule 116

PCT Art. 24(2), 48(2), PCT Rule 82bis, CPR Rule 103

CN.12
CPR Rules 6, CPR Rules 105
Subject to CPR Rule 105, where, because of force majeure, after having performed the acts necessary for entering the national phase, the time limit prescribed in the CPL or the CPR or specified by the Office is not observed, resulting in the loss of any right, the applicant may request restoration of his rights within two months from the date of the removal of the impediment, or, at the latest, within two years from the expiration of the time limit. Such a request should be accompanied by a statement of reasons for the failure to meet the time limit and any relevant supporting documents. Where, because of any justified reason, the time limit prescribed in the CPL of the CPR or specified by the Office is not observed, resulting in the loss of any right, the applicant may state the reasons and request the Office to restore his rights, within two months from the date of receipt of a notification from the Office.
CN.13 RESTORATION OF PRIORITY CLAIM
Where the International Bureau or the receiving Office has declared that the priority claim is considered not to have been made according to PCT Rule 26bis.2 and the related information has been published together with the international application, the applicant may, when entering the national phase, request restoration of the priority claim. The request for restoration of the priority claim is subject to the payment of a fee (for the amount, refer to Annex CN.I).
CN.14 UTILITY MODEL
CPR Rules 38, CPR Rules 39, PCT Rule 49bis.1(a), PCT Rule 76.5
If the applicant wishes to obtain a utility model instead of a patent in China, on the basis of an international application, the applicant, when performing the acts referred to in PCT Article 22 or 39, shall so indicate to the Office.
CN.15
The requirements for the national phase are basically the same as for patents, except that for utility models a drawing must be furnished and no examination as to substance is carried out.

Patents granted by the China National Intellectual Property Administration (CNIPA) are not automatically protected in the HKSAR but the grant of a patent by the China National Intellectual Property Administration (CNIPA) can form the basis for patents in the HKSAR. In order to obtain patents via the PCT, the applicant must designate China. Refer to paragraphs CN.17 to CN.19 of the chapter concerning the China National Intellectual Property Administration (CNIPA), in National Phase of the PCT Applicant’s Guide, for details of the national phase before the Intellectual Property Department (IPD) of the HKSAR.
