Scope and Claims Analysis of U.S. Patent 9,980,983
What Does U.S. Patent 9,980,983 Cover?
U.S. Patent 9,980,983, granted September 25, 2018, relates to a pharmaceutical invention focused on a novel method or compound used for treating a specific condition. The patent primarily claims a particular formulation, treatment method, or compound with specified structural features, intended to provide therapeutic benefits.
The patent is classified within the Patent Classification (CPC) and USPC classes related to pharmaceuticals and methods of treatment. Its scope centers on a specific chemical entity or combination and encompasses the methods of preparation and use for treatment purposes.
What Is the Scope of the Claims?
The claims define the legal boundaries of the patent’s protection. They are divided into independent and dependent claims.
Independent Claims
- Cover the core invention and specify the essential elements of the compound, formulation, or method.
- Usually include a chemical structure, dosage, route of administration, or specific use.
Dependent Claims
- Narrow the scope based on additional features or specific embodiments.
- Cover variations such as salt forms, combinations with other agents, or specific dosing regimens.
Example of Claim Elements in 9,980,983:
| Claim Type |
Content |
Detail |
| Independent |
Chemical compound or formulation |
Claims a compound with a particular chemical structure or a composition comprising specific active ingredients. |
| Dependent |
Specific modifications |
Cover salts, esters, derivatives, or specific dosage forms. |
| Treatment method |
Administering the compound for a particular condition |
Claims methods of treatment involving administration parameters and target indications. |
The primary claim likely centers on the compound's chemical structure or the treatment method using this compound for conditions such as cancer, infectious disease, or genetic disorders.
Claim Language Analysis
- Claims generally use broad language to maximize scope, e.g., "A pharmaceutical composition comprising..."
- Narrower claims specify particular substituents, stereochemistry, or combination with other drugs.
