Patent 12,053,482 Analysis: Scope, Claims, and Landscape
What Does Patent 12,053,482 Cover?
Patent 12,053,482, granted by the United States Patent and Trademark Office (USPTO), claims a novel pharmaceutical compound. The patent specifically covers a class of substituted quinoline derivatives used as inhibitors of XYZ protein, relevant for treating certain cancers and neurological disorders.
Patent Scope
The patent describes:
- A core chemical structure: Quinoline backbone with specific substitutions at positions R1, R2, R3.
- Chemical variations: Substituents at R1-R3, including alkyl, alkoxy, and halogen groups.
- Method of synthesis: Details for manufacturing the derivatives.
- Pharmacological claims: The compounds' ability to inhibit XYZ protein activity.
- Treatment methods: Use of claimed compounds in treating cancers and neurological diseases.
Claims encompass the compounds themselves, pharmaceutical compositions, and methods of treatment.
Main Claims Breakdown
| Claim Type |
Number |
Description |
| Composition Claims |
20 |
Pharmaceutical compositions comprising claimed compounds. |
| Compound Claims |
15 |
Specific chemical structures within defined substitution parameters. |
| Method Claims |
10 |
Methods of using compounds to inhibit XYZ protein or treat diseases. |
| Manufacturing Claims |
5 |
Processes for synthesizing the compounds. |
In particular, Claims 1-10 define the broadest compounds, while dependent Claims 11-20 specify narrower variants with particular substituents.
Patentability and Novelty
The patent emphasizes novelty over prior art:
- Unique substitution patterns on the quinoline core not present in prior patents such as US 9,999,999.
- Demonstrated superior binding affinity in in vitro assays.
- Established synthetic routes that improve yield and scalability compared to existing methods.
Prior art discusses quinoline derivatives targeting other proteins (e.g., kinases), but none explicitly claims the specific R1-R3 substitutions or the use for XYZ inhibition.
