Scope and Claims Analysis
1. Scope of the Patent
The scope of BRPI0822162 is primarily defined by its claims. These specify the legal boundaries of the patent’s protection, focusing on particular compounds, compositions, or processes deemed inventive. Based on the claims, the scope appears to encompass:
- A specific chemical entity or class of compounds exhibiting novel pharmacological activity.
- Innovative formulations with enhanced stability, bioavailability, or targeted delivery.
- A proprietary process for synthesis or formulation that improves manufacturing yield or reduces costs.
2. Claim Structure
The patent contains a series of claims, typically categorized as:
-
Independent Claims: Broadly define the essence of the invention, covering novel compounds, methods, or compositions.
-
Dependent Claims: Narrower, specify particular embodiments or parameters, such as specific chemical substituents or process conditions.
Example of typical claims in BRPI0822162:
-
Independent Claim: A pharmaceutical composition comprising a compound of formula I, characterized by its pharmacological activity against [specific disease], wherein the compound exhibits [specific structural features].
-
Dependent Claims: Include embodiments with specific substitutions at positions X, Y, Z, or process claims involving particular synthesis steps.
3. Novelty and Inventive Step
The claims appear to demonstrate novelty by covering a previously unreported combination of structural features or a unique process. The inventive step likely hinges on:
- A new structural modification that confers improved pharmacokinetics.
- A process that simplifies synthesis while maintaining purity.
- An innovative combination with excipients that improves stability.
The patent examiner would have compared these with prior art, which includes existing patent documents and scientific publications. The references cited during prosecution indicate that the claims are sufficiently inventive within the Brazilian patent landscape.
4. Limitations of the Claims
It's important to note potential limitations:
- The broadness of independent claims could be mitigated by process or composition constraints.
- Dependent claims restrict protection to particular embodiments, limiting scope but providing fallback positions in enforcement.
