Scope of the Patent: Claims Analysis
Claim Structure
Brazilian patents typically contain independent and dependent claims, with independent claims defining the broadest scope, and dependent claims adding specific embodiments and limitations.
BR112021026371 appears to comprise:
- A broad independent claim covering a pharmaceutical composition comprising a specific API or combination thereof, possibly with a unique excipient, delivery system, or formulation.
- Additional dependent claims detailing specific concentrations, dosage forms (e.g., tablets, injections), or stability features.
Scope Assessment
- Broad Claims: The independent claim likely covers a broad class of compounds or formulations, designed to prevent direct infringing uses while maintaining flexibility for different embodiments.
- Narrower Dependent Claims: These refine protections around specific dosage forms, manufacturing methods, or concentration ranges, narrowing the scope but strengthening enforceability in particular niches.
Novelty and Inventive Step
Brazil’s patentability criteria, aligned with INPI (Brazilian Patent and Trademark Office), demand that claims must be novel, inventive, and susceptible to industrial application. Based on the claims' language:
- Novelty: The patent appears to delineate specific combinations or methods not previously disclosed in prior art.
- Inventive Step: The claims' added features likely confer unexpected benefits, such as enhanced bioavailability or reduced toxicity, justifying inventive step.
Patent Landscape in Brazil: Pharmaceutical Sector
