Division在这里指的是专利的“分案”。维基百科中对其的定义如下：“A divisional patent application (sometimes referred to as a divisional application or simply a divisional) is a type of patent application which contains matter from a previously filed application (the so-called parent application). While a divisional application is filed later than the parent application, it may retain its parent's filing date, and will generally claim the same priority.”。

在美国，《专利法》规定一个专利申请只能包含一个发明。如果一个专利申请中包含多个发明，那么就需要进行分案申请（divisional application）。在我国，当一件专利包括两项以上的发明、实用新型或外观设计的，申请人可在收到专利局作出授予专利权通知书之日起二个月内向国务院专利行政部门提起分案申请。

美国的专利申请除了分案申请之外，还主要包括continuation-in-part application （部分延续申请）、reissue application（重新领证申请）:

Continuation application部分延续申请

（需要增加在母案申请中未披露的新的内容时，就需要申请部分延续案。）

A "continuation-in-part" application ("CIP" or "CIP application") is one in which the applicant adds subject matter not disclosed in the parent, but repeats substantial portion of the parent's specification, and shares at least one inventor with the parent application. The CIP application is a convenient way to claim enhancements developed after the parent application was filed.

reissue application重新领证申请

（已颁证的申请发现有些许瑕疵时，专利权人可放弃此专利，并申请重新领证，以改正该瑕疵）

If an issued patent is found to be defective, then the patent owner can surrender the patent and file a reissue application to correct the defect.

以下为相关例句：

Contractual Property Rights within the terms of this Agreement are the patent applications and patents (including co-owned patents) specified in Exhibit “A Property Rights” including all corresponding patents, patent applications, divisions, divisional applications, reissues, continuations and other property rights and applications for property rights that claim the same priority as the aforementioned patents and patent applications

本协议条款中的合同产权系指附件“A产权”中载明的专利申请和专利（包括共有专利），包括所有相关专利、专利申请、分案、分案申请、重新颁证专利、延续案和其他与前述专利和专利申请享有同等优先权的产权和产权申请。
