PCT案的修正時機

當接獲PCT申請案的檢索報告時，申請人可根據國際檢索報告（international search report）的結果提出權利範圍的修訂，並可同時提出簡要的說明，藉此解釋修訂內容（PCT第19條規定）。修正內容不得超過原說明書範圍

修改時機：接獲國際檢索報告之日後兩個月內，或是自優先權日起16個月內，以較晚的時間為準，但若逾期，在國際公佈準備完成前提出，仍可能被接受

Article 19
Amendment of the Claims before the International Bureau
(1) The applicant shall, after having received the international search report, be entitled to one opportunity to amend the claims of the international application by filing amendments with the International Bureau within the prescribed time limit. He may, at the same time, file a brief statement, as provided in the Regulations, explaining the amendments and indicating any impact that such amendments might have on the description and the drawings.
(2) The amendments shall not go beyond the disclosure in the international application as filed.
(3) If the national law of any designated State permits amendments to go beyond the said disclosure, failure to comply with paragraph (2) shall have no consequence in that State.

另有一修正時機，也就是進入國際初步審查階段（international preliminary examination）時
通常當申請人接獲國際檢索報告後，也會提出國際初步審查的請求
根據PCT第34條規定，當提出國際初步檢索請求時，申請人可在國際局做出初步審查報告前，提出權利範圍、說明書內容與圖式的修訂（不能超出原說明書範圍），甚至提出口頭溝通

Article 34(2)(b)
The applicant shall have a right to amend the claims, the description, and the drawings, in the prescribed manner and within the prescribed time limit, before the international preliminary examination report is established. The amendment shall not go beyond the disclosure in the international application as filed.

經初步審查後，若申請案所載發明具有專利性（Art 33(1)）、符合規定，並無需其他補充文件，否則應該會接獲審查意見。審查意見中，若有單一性問題，可提出權利範圍方面的限制，或是繳費以取得全部範圍的審查意見，未被選擇的範圍則考慮進入國家階段時撤回

申請人之後可針對審查意見提出回應
