What is the scope of U.S. Patent 9,078,814?
Broad Overview
The patent claims focus primarily on novel compounds and associated methods for treating Parkinson’s Disease by administering specific chemical entities that modulate neurodegeneration processes. It emphasizes:
- Chemical compounds: Structurally defined molecules with specific substitution patterns.
- Method of use: Administering these compounds to alleviate PD symptoms or slow disease progression.
- Pharmacological effects: Neuroprotection, dopamine restoration, and reduced neuroinflammation.
Claims are structured to cover both the compounds themselves and their therapeutic applications, effectively creating a dual-layered protection.
Scope of Claims
Claim 1 (Independent Claim):
A method of treating Parkinson’s Disease in a subject in need thereof, comprising administering to the subject an effective amount of a compound of Formula I:
[
\quad \text{(chemical structure)}
]
wherein the defined substituents [R1, R2, R3, etc.] are as described, with the molecule configured for central nervous system bioavailability, neuroprotective effects, or dopamine receptor modulation.
Claims 2-10 (dependent claims):
- Specify particular substitutions and stereochemistry for compounds of Formula I.
- Cover dosage ranges from nanomolar to milligram quantities.
- Encompass administration routes: oral, intravenous, intranasal.
- Include formulations, such as tablets, injections, or transdermal patches.
- Broadening to derivatives with similar pharmacological profiles.
Chemical Scope
- The core chemical class encompasses benztropine derivatives with specific substitutions on the aromatic ring and amine groups, identified during patent prosecution as having neuroprotective capabilities.
- Structural variations: Modifications to improve pharmacokinetics or reduce side effects.
Methodology Scope
- The patent claims cover single and combination therapies, including co-administration with levodopa and other PD medications.
- The claims support both prophylactic and therapeutic uses.
- Additional claims extend to preclinical models for screening purposes.
