Understanding Restriction [Patent]: Key Legal Insights
Definition & Meaning
A restriction in patent law occurs when an applicant submits a patent application that includes two or more distinct inventions. In such cases, the patent examiner will require the applicant to select one invention to pursue. This process is known as a requirement for restriction or division. The examiner typically issues this requirement before any substantive examination of the application, but it can be made at any time prior to the final decision on the application.
