- Publication Date: January 21, 2022
- Applicant: PharmaTech Innovations
- Target Indications: Neurodegenerative disorders (Alzheimer’s, Parkinson’s, ALS)
- Type: Patent of invention (patente de invenção)
- Focus: Pharmaceutical compositions comprising specific combinations of active pharmaceutical ingredients (APIs) for neurodegeneration
Main Components of Scope
1. Therapeutic Composition
The patent claims a composition comprising:
- A dopaminergic agent (e.g., levodopa or similar compounds)
- An antioxidant agent (e.g., coenzyme Q10 or vitamin E)
- A neuroprotective agent (e.g., memantine or N-acetylcysteine)
- Optional excipients suitable for oral or injectable formulations
2. Method of Treatment
The patent claims a method of administering the composition to a patient exhibiting symptoms or diagnosed with a neurodegenerative disease, with specific dosage ranges and administration schedules.
3. Novelty & Inventive Step
The novelty principally resides in the specific combination and dosage regimens that exhibit synergistic effects, reducing disease progression markers in preclinical models.
Claims Breakdown
Claim Types
| Type of Claim |
Scope & Examples |
| Independent Claims |
Broad formulations and treatment methods. E.g., "A pharmaceutical composition comprising..." |
| Dependent Claims |
Specific embodiments, e.g., specific active compounds, dosages, or administration modes. |
Sample Independent Claim
Claim 1: A pharmaceutical composition for treating neurodegenerative diseases, comprising: a dopaminergic agent, an antioxidant agent, and a neuroprotective agent, wherein the composition is suitable for oral administration.
Dependent Claims
- Specific combinations such as levodopa + coenzyme Q10 + memantine.
- Dosage ranges, e.g., levodopa at 100–300 mg/day.
- Formulation specifics, e.g., tablet, capsule, or injectable form.
- Method claims involving patient administration over a period of 4–12 weeks.
Scope Analysis
The scope covers both composition claims (broad, encompassing various active agents within defined classes) and method claims (administration protocols). The claims notably emphasize:
- Synergistic combinations for enhanced neuroprotection.
- Formulation flexibility (oral, injectable).
- Targeted indications, primarily neurodegenerative conditions.
The scope is designed to protect both the inventive composition and its clinical application, a strategy aligned with therapeutic patents seeking broad protection against similar formulations.
Patent Landscape for Neurodegenerative Therapeutics in Brazil
Legal and Regulatory Context
Brazil’s patent system under INPI (Instituto Nacional da Propriedade Industrial) conforms with TRIPS Agreement standards, requiring invention novelty, inventive step, and industrial applicability. Pharmaceutical patents must also navigate prior art, which includes both local and international patents, as well as existing formulations and methods.
