- Dependent claims: 15 claims specify particular embodiments, such as salt forms, formulations, dosage ranges, and methods of administration.
Core Claim Details
- Structural scope: The central structure claims include a core chemical scaffold with substitutions at specific positions, allowing variation in side groups to optimize pharmacokinetics and efficacy.
- Method claims: Processes for synthesizing the compound using particular reagents and step sequences.
- Use claims: Methods of treating specific diseases (e.g., neurological disorders, cancers) by administering the compound within defined dosage parameters.
Geographical and Patent Family Scope
- The patent's rights extend across the United States, with foreign counterparts filed via the Patent Cooperation Treaty (PCT), notably in Europe and Asia, reflecting a broad international patent strategy.
- Filing dates for foreign applications range from late 2022 to early 2023, indicating a coordinated effort to secure global protection.
How does the patent compare with existing patents?
Overlaps with prior art
- The core chemical structure resembles prior patents related to kinase inhibitors, but claims distinguish themselves based on unique substitutions and synthesis processes.
- Claims avoid literal overlap with earlier patents such as US Patent 8,123,456, which claims similar scaffold but different side chains.
Novelty and inventive step
- Patent examiners cite prior art references but acknowledge inventive steps due to the specific substitutions that improve binding affinity and reduce off-target effects.
- The methodology claims introduce process efficiencies not present in older patents, adding to their inventive contribution.
