<\/p>\n

When the Japan Patent Office (JPO) issues a design Office Action (Notice of Reasons for Refusal), the applicant must respond by a set deadline. Foreign applicants — that is, applicants who are not resident in Japan — are given an initial response period of three months.<\/span><\/p>\n

This period can be extended. At the examination stage, an extension is available without any specific reason<\/span>. Even if the original deadline is missed, a late-filing extension of two months may still be possible. The two types of extension cannot be combined, so the maximum response period is five months.<\/p>\n

At the appeal stage, only one extra month is available<\/span>. Once that deadline has passed, no extension is possible.<\/p>\n

One deadline cannot be extended at all<\/span>: the period for filing an appeal against a decision of refusal. For designs this period is three months, even for foreign applicants. Patent practice is different here, so this point needs care.<\/p>\n

This guide explains the current rules on response periods and extensions for foreign applicants filing design applications in Japan<\/strong>.<\/p>\n

    <\/p>\n

    2. Response period for a design Office Action<\/h2>\n

    When the JPO issues an Office Action, the applicant must respond within the period set by the examiner. For foreign applicants, the initial period is three months in each of the cases below.<\/p>\n

    \n
    \n\n\n\n\n\n\n\n
    Type of notice<\/th>\nInitial response period<\/th>\n<\/tr>\n<\/thead>\n
    Office Action at the examination stage<\/span>
    (national design application)<\/td>\n    		3 months*<\/span><\/td>\n<\/tr>\n
    Notification of refusal<\/span>
    (international design registration under Hague system)<\/td>\n    		3 months<\/span><\/td>\n<\/tr>\n
    Office Action at the appeal stage<\/span>
    (after appeal against decision of refusal has been filed)<\/td>\n    		3 months*<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

    Initial response periods for foreign applicants<\/span><\/p>\n<\/div>\n

    \n
    ⚠️ One exception to be aware of (*)<\/div>\n
    \n

    Under Formality Examination Manual 04.10 (section 2(2)), the three-month period is shortened to 40 days<\/span> where the JPO considers that the local representative can prepare the document alone<\/span>, without input from the applicant.<\/p>\n

    This shortening applies only to an Office Action on a national design application<\/span>. It can apply at the examination stage and at the appeal stage alike. For a notification of refusal<\/span> in a Hague application, the period is three months in every case<\/span> and is not shortened on this ground.<\/p>\n

    In practice, a written opinion (arguments) normally needs instructions from the applicant, so three months is the usual period. Even so, always check the length of the period stated on the notice<\/span> rather than assuming three months.<\/p>\n<\/div>\n<\/div>\n

    <\/p>\n

    3. Extension at the examination stage<\/h2>\n

    <\/p>\n

    \n

    * Not available if an extension was already given before the deadline, or if a written opinion was filed within the initial period<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    <\/p>\n

    Extension before the deadline<\/h3>\n

    At the examination stage, no reason has to be given for an extension<\/span>. The extension structure is as follows:<\/p>\n

    \n
    📌 Extension before the deadline (foreign applicants)<\/div>\n
    \n
      \n
    • Extension given: 2 months<\/span><\/li>\n
    • Number of requests: one only<\/span><\/li>\n
    • Valid reason: Not required<\/span><\/li>\n
    • Fee: JPY 2,100<\/span><\/li>\n
    • Maximum response period: 5 months<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n

      Note one difference from patent practice. For a patent, you can file a second request and gain one further month. For a design, only one request is allowed<\/span>, and two months is the limit.<\/p>\n

      Extension after the deadline (Late-filing extension)<\/h3>\n

      If the response deadline has been missed, a late-filing extension may still be available<\/span> at the examination stage.<\/p>\n

      \n
      📌 Late-filing extension (foreign applicants)<\/div>\n
      \n
        \n
      • Filing window: within 2 months<\/span> from the day after the original deadline<\/li>\n
      • Extension given: 2 months<\/span> from the day after the original deadline<\/li>\n
      • Valid reason: Not required<\/span><\/li>\n
      • Fee: JPY 7,200<\/span><\/li>\n
      • Number of requests: one only<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n

        When a late-filing extension is not available<\/h3>\n

        The extension after the deadline is not available in the following cases.<\/p>\n

        \n
        ⚠️ Unavailable cases<\/div>\n
        \n
          \n
        • An extension was already given before the deadline.<\/span> The two types of extension cannot be combined.<\/li>\n
        • A written opinion (arguments) was already filed within the initial period.<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n

          The rule refers only to a written opinion. An amendment does not have the same effect<\/span>: if the applicant filed only an amendment within the initial period, and no written opinion, an extension after the deadline is still available. This treatment has been confirmed with the JPO.<\/p>\n

          Comparing the two extension patterns<\/h3>\n

          Because the two types of extension cannot be combined, you have to choose one of them.<\/p>\n

          Both patterns result in five months in total. The fee is different, and Pattern B costs more than three times as much. For most cases, the safer approach is to plan around the initial three months, or around a period extended by a request filed before the initial deadline (Pattern A). Pattern B is best kept as a fallback for when more time proves unavoidable.<\/p>\n

          \n
          \n\n\n\n\n\n\n\n\n\n\n
          <\/th>\nPattern A
          Before only<\/th>\n          		Pattern B

          Initial period<\/span><\/td>\n3 months<\/td>\n3 months<\/td>\n<\/tr>\n
          Before deadline<\/span><\/td>\n+2 months<\/td>\n\u2014<\/td>\n<\/tr>\n
          After deadline<\/span><\/td>\n\u2014<\/td>\n+2 months<\/td>\n<\/tr>\n
          Maximum response period<\/span><\/td>\n5 months<\/span><\/td>\n5 months<\/span><\/td>\n<\/tr>\n
          Fee<\/span><\/td>\nJPY 2,100<\/td>\nJPY 7,200<\/span><\/td>\n<\/tr>\n
          Condition<\/span><\/td>\n—<\/td>\nNo extension request and no written opinion within the initial period<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

          The two extension patterns give the same total period<\/span><\/p>\n<\/div>\n

          <\/p>\n

          4. Extension at the appeal stage<\/h2>\n

          <\/p>\n

          \n
          Appeal stage: response period extension<\/div>\n
          \n
          Extension before<\/span> the deadline<\/div>\n
          \n3 months<\/span>
          \n+<\/span>
          \n1 month<\/span>
          \n(1 request only)<\/span><\/p>\n
          \nNo reason required<\/span>JPY 2,100<\/span>\n<\/div>\n
          * Available to foreign applicants only<\/div>\n<\/div>\n<\/div>\n
          \n
          Extension after<\/span> the deadline<\/div>\n
          \nNot available<\/span>\n<\/div>\n<\/div>\n<\/div>\n

          <\/p>\n

          Where an Office Action is issued after an appeal against a decision of refusal has been filed, the rules are stricter than at the examination stage<\/span>.<\/p>\n

          \n
          📌 Extension at the appeal stage (foreign applicants)<\/div>\n
          \n
            \n
          • Extension given: 1 month<\/span> (maximum)<\/li>\n
          • Valid reason: Not required<\/span><\/li>\n
          • Fee: JPY 2,100<\/span><\/li>\n
          • Extension after the deadline: Not available<\/span><\/li>\n
          • Maximum response period: 4 months<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n

            Because no extension is available once the deadline has passed, deadline management at the appeal stage needs to be considerably tighter than at the examination stage<\/span>. The practical maximum is four months, and there is no safety net beyond it.<\/p>\n

            <\/p>\n

            (Reference) The period for filing an appeal against a decision of refusal cannot be extended<\/h3>\n

            \nNo extra month for foreign applicants<\/span>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

            <\/p>\n

            An appeal against a decision of refusal must be filed within three months<\/span> from the day after the certified copy of the decision is served. This period is set by law and cannot be extended<\/span>. The JPO will not extend it on its own initiative either.<\/p>\n

            A relief provision does exist under Article 46(2) of the Design Act for cases where the deadline was missed for reasons beyond the applicant’s control. However, the requirements are strict, and it is not a substitute for ordinary deadline management.<\/p>\n

            5. Frequently asked questions<\/h2>\n
            \n
            \n
            Q1. How long is the response period for a JPO design Office Action for foreign applicants?<\/div>\n
            \nThe initial response period is three months<\/span> at both the examination stage and the appeal stage. The same three-month period applies to a notification of refusal in a Hague application.\n<\/div>\n<\/div>\n<\/div>\n
            \n
            \n
            Q2. How long can the response deadline for a design Office Action be extended at the examination stage?<\/div>\n
            \nYou can extend the period by two months<\/span> with a single request. No reason is required, and the fee is JPY 2,100. Together with the initial three months, this gives a maximum response period of five months<\/span>. Only one request is allowed.\n<\/div>\n<\/div>\n<\/div>\n
            \n
            \n
            Q3. What happens if the response deadline for a design Office Action is missed?<\/div>\n
            \nAt the examination stage, you can request a late-filing extension within two months<\/span> after the original deadline. The fee is JPY 7,200<\/span>. This route is not available if an extension was already given before the deadline, or if a written opinion was already filed. At the appeal stage, no late-filing extension is available.\n<\/div>\n<\/div>\n<\/div>\n
            \n
            \n
            Q4. Can the extension before the deadline and the late-filing extension be combined?<\/div>\n
            \nNo. For designs the two types of extension cannot be combined<\/span>. If you request an extension before the deadline, you cannot request a further extension afterward. Patent practice is the same on this point, but trademark practice differs, since the two can be combined for trademarks.\n<\/div>\n<\/div>\n<\/div>\n
            \n
            \n
            Q5. Can the response period be extended at the appeal stage?<\/div>\n
            \nYes, but only by one month<\/span>, and only for foreign applicants. No reason is required, and the fee is JPY 2,100. This gives a maximum response period of four months. No extension is available once the deadline has passed.\n<\/div>\n<\/div>\n<\/div>\n
            \n
            \n
            Q6. Can the period for filing an appeal against a decision of refusal be extended?<\/div>\n
            \nNo. The period is three months<\/span> and cannot be extended. Unlike patent practice, no extra month is added for foreign applicants. A limited relief route exists where the deadline was missed for reasons beyond your control (Design Act Article 46(2)).\n<\/div>\n<\/div>\n<\/div>\n
