Divisional Application: Key Insights into Patent Applications

Definition & Meaning

A divisional application is a type of patent application that is based on the same disclosure as an original (or parent) application but claims a different invention. Patent law typically allows only one invention to be claimed in a single application. If an application includes multiple inventions, the applicant may be required to elect one invention for prosecution. The other inventions can then be pursued through a divisional application, which retains the same filing date as the original application. Divisional applications are also referred to as restricted applications.

Example 2: A company submits a patent application for a new software algorithm. If the application includes additional features that are distinct but related, the company may file a divisional application to cover those features. (hypothetical example)
