What is the scope of patent CA3107182?
Patent CA3107182 covers a novel method of treating certain conditions using specific pharmaceutical compounds. Filed by a global pharmaceutical company in 2018, the patent grants protection until 2038. The patent's scope includes claims for a chemical composition, its manufacturing process, and specific therapeutic uses.
Key features:
- Target indication: Neurological disorders, particularly Alzheimer’s disease.
- Compound class: Biflavonoids with increased bioavailability.
- Delivery method: Oral administration with controlled-release formulations.
- Novelty: Variants with specific hydroxylation patterns to improve brain penetration.
What do the claims encompass?
The patent contains both independent and dependent claims, primarily focusing on:
Independent claims
- A pharmaceutical composition comprising a biflavonoid compound with specified hydroxylation patterns.
- A method of treating neurodegenerative diseases by administering the composition.
- A process for synthesizing the biflavonoid with higher bioavailability.
Dependent claims
- Specific versions of the biflavonoid compound with particular substituents.
- Formulations combining the compound with other neuroprotective agents.
- Use of the compound in dosage ranges from 10 mg to 100 mg daily.
Claim scope analysis
The claims aim to protect the chemical structure of the biflavonoids, their synthesis, and therapeutic application. The breadth includes derivatives with similar hydroxyl substitutions, covering a broad scope to deter alternative synthesis routes.
