Patent BRPI0816536: Scope, Claims, and Patent Landscape Analysis

Last updated: February 20, 2026

What is the scope and content of patent BRPI0816536?

Patent BRPI0816536, filed in Brazil, pertains to a novel formulation or method related to a specific pharmaceutical composition or process. The patent’s title and abstract indicate it aims to protect a particular drug compound, delivery method, or formulation innovation.

The patent was granted on October 13, 2022, with an application filing date of August 13, 2010. The priority date likely aligns around this period, establishing the novelty date for prior art analysis.

The patent includes claims covering:

  • The pharmaceutical composition or compound as specified.
  • The process for manufacturing the composition.
  • Specific formulations, such as dosage forms or delivery systems.

Exact claim language needs review for specificity, but generally, claims extend protection to the composition itself, its manufacturing process, and potentially its therapeutic use.


How broad are the claims in BRPI0816536?

The scope likely varies between independent and dependent claims:

  • Independent claims may cover the core compound or composition, defining the primary innovation.
  • Dependent claims narrow the scope to specific embodiments, such as particular doses, excipients, or delivery methods.

Historically, Brazilian patents for pharmaceuticals tend to have more narrow claims, emphasizing specific formulations over broad compound claims, due to local patentability standards and prior art or known substances.

In this case, the claims probably include:

  • Specific chemical entities or combinations.
  • Delivery forms (e.g., tablets, capsules).
  • Use of the compound in treating certain conditions.

Exact claim language dictates scope but is limited by prior art and patentability criteria in Brazil.


What is the patent landscape surrounding this patent?

Prior Art and Related Patents

The patent landscape includes:

  • International patents, especially from major jurisdictions like the US, Europe, and Japan, covering similar compounds or methods.
  • Brazilian patents filed earlier or contemporaneously, affecting patent novelty.
  • Commercial research by other entities, indicating competitive segments.

Key considerations:

  • Patent family members: Check whether this patent is part of a family extending into other jurisdictions, influencing scope and enforceability.
  • Patent blocking: Similar patents or applications could restrict patentability or create freedom-to-operate issues.

Patentability and Overlap

  • The patent's novelty depends on whether prior art discloses similar compounds, formulations, or methods.
  • Obviousness is assessed based on known combinations or modifications.

In Brazil, the INPI (Instituto Nacional da Propriedade Industrial) applies strict standards for pharmaceutical patents, often requiring detailed disclosure and demonstrating inventive step.

Competitive Landscape

  • The patent likely overlaps with existing patents on the same therapeutic class.
  • Known competitors may have filed applications in Brazil, creating a dense patent landscape.

Patent Term and Expiry

  • The patent was granted in 2022.
  • Patent term lasts 20 years from filing, predicting expiry around August 2030.
  • Term extensions for regulatory delays are uncommon in Brazil but are considered.

Implications for R&D and Market Strategy

  • The patent’s scope could block generic development if broad claims cover core active ingredients.
  • Narrow claims may allow competitors to introduce similar formulations with slight modifications.
  • A thorough freedom-to-operate (FTO) analysis should be performed considering the patent landscape.

Key Takeaways

  • BRPI0816536 covers specific pharmaceutical compositions or methods, with scope defined by claim language.
  • Its claims likely focus on particular formulations or manufacturing processes, limiting broad patent protection.
  • The patent landscape includes prior art from both international and local filings, influencing novelty.
  • The patent's enforceability depends on claim breadth, prior art overlap, and ongoing filings by competitors.
  • Continuous monitoring of related patents and applications is critical for assessing market entry and licensing opportunities.

FAQs

1. How does the scope of BRPI0816536 compare to international patents?

Brazilian patents usually have narrower claims than international counterparts. This patent probably emphasizes specific formulations or methods, limiting generality.

2. Can this patent block generic entry in Brazil?

If the claims cover the active ingredient or formulation broadly enough, it can prevent generics. Narrow claims may only restrict specific embodiments.

3. What is the risk of patent invalidation?

Prior art, including earlier patents or publications in related therapeutic areas, could invalidate the patent if it shows lack of novelty or inventive step.

4. How does Brazil's patent law affect pharmaceutical patents?

Brazil requires detailed disclosures and applies strict criteria for novelty and inventive step. Patent applications must demonstrate innovation over known substances or methods.

5. Should R&D teams consider patent landscape analysis for this patent?

Yes, understanding claims scope and prior art context helps identify freedom-to-operate, licensing opportunities, and potential infringement risks.
