經再審(reexamination)修改專利範圍（USC 307）

美國專利法第307條規範了經再審（re-exam）後的專利性、非專利性與權利刪除的證明

§307. Certificate of patentability, unpatentability, and claim cancellation
(a)In a reexamination proceeding under this chapter, when the time for appeal has expired or any appeal proceeding has terminated, the Director will issue and publish a certificate canceling any claim of the patent finally determined to be unpatentable, confirming any claim of the patent determined to be patentable, and incorporating in the patent any proposed amended or new claim determined to be patentable.
在再審階段，當訴願時間過期或是結束後，USPTO主管將公開經確認的權利範圍，包括刪除不可專利的權利，即確認可專利的部份，或是新增權利範圍
(b)Any proposed amended or new claim determined to be patentable and incorporated into a patent following a reexamination proceeding will have the same effect as that specified in section 252 of this title for reissued patents on the right of any person who made, purchased, or used within the United States, or imported into the United States, anything patented by such proposed amended or new claim, or who made substantial preparation for the same, prior to issuance of a certificate under the provisions of subsection (a) of this section.
任何經過再審階段後，經修改或是新增的權利範圍的效果將等同於再領證（reissue）的範圍的規定，同樣及於製造、販賣、使用與進口的侵權行為
但再審後新增或修改的範圍，則如reissue一樣，不及於領證前已經完成的製造、販賣、使用與進口的行為

舉例
在瀏覽US5,579,517時，發現檔案後面顯示經過再審（Re-examination）的內容
發現，原本核准的四個範圍經過再審後新增到44項（這個過程並未詳細研究）
(此案是經過Terminal Disclaimer)

雖然權利範圍不見得有比原範圍廣，但是在日後主張權利時，卻是又增加了不少武器！

經Reexamination Certificate後，還核發另一個專利號US 5,579,517 C1


以下訊息顯示，Claim 1經過一些修改、Claim 2-4維持原樣、Claim 5-44為新增，皆確認為可專利
