The patent title is "Substituted amino-piperidine compounds for treating neurological disorders." The patent claims relate primarily to the synthesis, chemical structure, and therapeutic application of these compounds, with emphasis on their potential as modulators of neurological pathways.
The patent's core scope focuses on:
- Chemical structure: The compounds claimed feature a piperidine ring substituted with particular pharmacophores, including amino groups and aromatic substituents with specific positional arrangements.
- Method of synthesis: The patent discloses multiple synthetic routes for these compounds, including intermediates and reaction conditions.
- Therapeutic claims: The compounds are claimed for use in treating neurological disorders such as depression, anxiety, and Parkinson's disease.
In terms of patent family, the application sets the groundwork for broad coverage, aiming to include various derivatives within the claimed chemical space, which suggests an intention to secure broad patent protection beyond specific examples.
How are the claims structured?
The patent claims are divided into independent and dependent claims, with the independent claims establishing the broadest scope.
Key independent claims:
-
Claim 1: A compound selected from the group comprising a substituted amino-piperidine derivative with specific substituents on the aromatic ring and amino group configurations.
-
Claim 15: A method of synthesizing the compound of claim 1 via a specified reaction pathway involving reaction of a piperidine core with particular reagents under defined conditions.
-
Claim 30: A method for treating a neurological disorder comprising administering an effective amount of the compound claimed in Claim 1.
Dependent claims specify:
- Variations in chemical substituents (e.g., alkyl, alkoxy, halogen groups).
- Specific stereochemistry (e.g., R or S configurations).
- Use in particular disorders or patient populations.
Claim language style:
Claims employ Markush groups, allowing substitution of various functional groups, which broadens patent coverage. They specify structural features with enumerated alternatives,重要 to understand the breadth and limitations.
Patent scope implications:
The breadth of Claim 1 indicates coverage of a wide chemical class, while dependent claims narrow the scope to specific derivatives, facilitating enforcement against close competitors.
