    The Office has available special forms for entering the national phase (refer to Annex CN.II for invention applications and Annex CN.III for utility model applications). These forms should preferably (but need not) be used when effecting the payment of the national fee and for the furnishing of the translation of the international application into Chinese. The forms are also available on the Office’s website at http://www.cnipa.gov.cn.
    CN.02 TRANSLATION (CORRECTION)
    Errors in the translation of the international application can be corrected with reference to the text of the international application as filed (refer to National Phase, paragraphs 6.002 and 6.003).

    With regard to an international application for a utility model, the applicant may file a request with the Office to amend the description, drawings and claims on his own initiative within two months from the date of entry into the national phase. 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),

    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 60,
    CPR Rules 115

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.

    PCT Art. 24(2),
    PCT Art. 48(2),

    CN.12
    CPR Rules 6,
    CPR Rules 122

    Subject to CPR Rule 122, 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 and 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, within two months from the date of entering the national phase, request restoration of the priority claim.

    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. An international application for a patent may not be converted into a utility model application, and vice versa.
    CN.16 APPEALS
    CPL Art. 41,
    CPR Rules 65,
    CPR Rules 66,
    CPR Rules 67,
