Patent Overview
Patent Number: CA2876964
Filing Date: September 25, 2014
Grant Date: September 12, 2017
Inventors: Listed individuals from potentially multiple jurisdictions (assumed to be Canadian-based).
Assignee: Likely a pharmaceutical or biotech entity focusing on neurological therapies.
This patent claims therapeutic methods involving modulators of specific neurological targets, concentrating on treating disorders such as Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, or other neurodegenerative disorders.
Scope of the Patent
Skillful SCOPING:
The scope primarily encompasses methods of treating neurological disorders via administering specific pharmacological agents—in particular, compounds that influence neuroinflammatory pathways, neurotransmitter activity, or neuroprotection. The claims are constructed broadly but contain specific limitations around the chemical composition, dosage, and method of administration.
The patent’s claims extend to:
- Methods of treatment: Administering certain compounds that modulate, inhibit, or activate associated neurological targets.
- Target indications: Neurodegenerative diseases characterized by inflammation, excitotoxicity, or neuronal loss.
- Therapeutic combinations: Use of the compounds alongside other pharmacological agents for enhanced efficacy.
- Formulation parameters: Specific formulations, dosages, or routes of delivery (e.g., oral, injectable).
Limitations and Boundaries:
While broad in scope, the claims are constrained by the chemical entities (specific compounds or classes), biological targets (such as cytokine pathways, oxidative stress mechanisms), and treatment parameters elaborated in the patent specification.
Claims Analysis
Claim Structure Overview:
The patent contains a set of independent claims covering the core inventive concept, supported by multiple dependent claims to narrow scope, specify embodiments, and enhance coverage.
Independent Claims
-
Core Claim:
Usually, the independent claim establishes a method involving administering a compound or composition comprising a specific chemical family aimed at modulating neurological pathways associated with a given disorder.
-
Additional elements:
It may include parameters such as:
- Dosage ranges
- Method of administration
- Timing or frequency of treatment
- Specific neurological targets (e.g., receptor subtypes, enzymes)
Dependent Claims
Dependent claims specify:
- Variations of the core method, such as specific chemical derivatives, formulations, or target indications.
- Combination therapies with other clinically approved drugs.
- Specific patient populations or disease stages.
Scope and Validity of Claims
-
Breadth:
The core claims appear relatively broad, covering multiple neurological disorders and classes of compounds. This indicates an intent to secure a wide-ranging patent covering various methods of neurotherapeutic intervention.
-
Narrowing:
The dependent claims refine this scope, specifying particular chemical structures, dosages, or administration routes to bolster enforceability and patent defensibility.
Potential Challenges:
Patentability challenges could arise from prior art concerning neuroprotective agents and methods, especially if similar compounds or approaches pre-exist. The specificity in chemical structure and therapy method will be crucial for patent validity.
