Legal Definitions - new-use claim

A new-use claim is a type of patent claim that describes a new way of using an existing invention. For example, a new-use claim could be made for a medication that was originally developed to treat one condition but is now being used to treat a different condition. This type of claim is a method claim, which means it describes the steps that need to be taken to achieve the desired result.

For instance, a new-use claim could be made for a medication that was originally developed to treat high blood pressure but is now being used to treat migraines. The claim would describe the steps that need to be taken to use the medication to treat migraines, such as the dosage and frequency of administration.
