What is the Scope of U.S. Patent No. 9,216,982?
Patent Classification and Field
- International Patent Classification (IPC): The patent is likely classified under classes related to pharmaceuticals, such as A61K (preparations for medical, dental, or hygienic purposes), which covers drug compositions, and C07D (heterocyclic compounds), if applicable.
- Field of Application: The patent involves specific drug compositions, potentially targeting therapeutic indications such as oncology, neurology, or infectious diseases, based on the chemical or biological entities disclosed.
Claims Overview
The claims define the scope by delineating the novel features, focusing on:
- Specific chemical compounds or derivatives.
- Novel formulations with particular excipients or delivery systems.
- Methods of treatment employing these compounds.
Types of Claims
- Independent Claims: Broad claims covering the core compounds or methods, aiming to capture the patent’s fundamental inventive concept.
- Dependent Claims: Narrower claims that specify particular embodiments, modifications, or usages.
