Best Practices for Design Patents- Include Additional Embodiments

By Debby Winters

To continue our series of blog posts on design patents, in this post we will discuss including additional embodiments.  Similar concepts with slightly different modifications, such as certain features being shown in solid and broken lines, are considered additional embodiments and could be filed in the same application. The potential outcome of including additional embodiments in a design application that does not exist in a utility application is the potential for receiving a restriction requirement.  The Patent Office may or may not issue a restriction requirement, depending on how closely related the designs are. The subjectivity will also depend upon the particular Examiner assigned to your application. Including different embodiments allows different levels of protection for the same invention. There is no downside to including embodiments of different scope in the same application. The Patent Office will issue a restriction if warranted, and subsequent divisional applications can be filed that are directed to the restricted embodiments.

Alternatively, an Appendix including additional or related embodiments may be filed in the application. The Appendix will serve as support for future drawing amendments or continuation applications and should be canceled by the Examiner upon allowance of the application.
