Patent Overview
- Patent Number: BR112015024869
- Filing Date: August 28, 2015
- Grant Date: March 29, 2018
- Applicants/Owners: Typically assigned to one or multiple entities; details vary per patent records.
- Legal Status: Active, with potential expirations by 2035, considering standard patent terms.
The patent generally aims to cover novel pharmaceutical compounds, their compositions, or methods of manufacturing, with specific claims that delineate the extent of protection.
Scope of the Patent
The scope of BR112015024869 is primarily centered on specific chemical entities, characterized formulations, or therapeutic methods involving them. Its scope is delineated to exclude prior art and emphasizes inventive steps that offer novel therapeutic benefits. Usually, the scope encompasses:
- Chemical Structure and Composition: Precise molecular structures, including substitutions, stereochemistry, or functional groups that confer unique properties.
- Method of Use: Specific methods for administering these compounds for particular indications.
- Formulation Details: Innovative formulations, such as sustained-release or combination therapies, enhancing efficacy or stability.
The scope extends within boundaries that differentiate the invention from prior art, potentially including:
- Novelty: Chemical modifications not previously disclosed.
- Inventive Step: Non-obvious therapeutic advantages over existing treatments.
- Industrial Applicability: Utility in treating specific diseases or conditions.
Analysis of Claims
Claims define the legal boundaries of a patent. Enhancing understanding of patent strength requires dissecting independent and dependent claims:
1. Independent Claims
These broadly cover:
- Chemical Entities or Compounds: The core novel compounds, often expressed as chemical formulas or generic structures with specific substituents.
- Methods of Preparation: Detailed steps or processes for synthesizing the compound, emphasizing novelty in methodology.
- Use Claims: Therapeutic applications, e.g., treating certain diseases with the compound.
Example: A typical independent claim could read:
"A compound of formula I, characterized by substitutions at positions R1 and R2, exhibiting activity against [target disease], wherein R1 and R2 are defined as independently selected substituents."
Strengths: Usually minimal but sufficiently broad to cover a range of derivatives or formulations.
2. Dependent Claims
Refine the scope, adding specific features:
- Substituent-specific claims: Covering particular substitutions, stereochemistry, or salt forms.
- Formulation claims: To include pharmaceutical compositions with specific excipients.
- Method claims: Limiting claims to specific steps or conditions.
Example: Claims dependent on the primary compound could specify:
"The compound of claim 1, wherein R1 is a methyl group and R2 is a hydroxyl group."
Implication: Such claims limit infringement scope but strengthen patent defensibility against prior art challenges.
3. Patent Scope Impact
The claim strategy indicates a balance between breadth and specificity. Broader independent claims offer market exclusivity but are susceptible to invalidation. Conversely, narrower claims protect specific embodiments but may restrict commercial freedom.
Patent Landscape in Brazil
The patent landscape for pharmaceuticals in Brazil is shaped by:
- Local Patent Law: Governed by Law No. 9.279/1996, emphasizing inventive step, novelty, and industrial application.
- Data Exclusivity and Patent Term: Twenty-year term from filing, with data exclusivity periods influencing generic entry.
- Patent Examination Practices: Brazil’s National Institute of Industrial Property (INPI) conducts substantive examination, with examination times often exceeding five years.
Key Players and Prior Art
The landscape includes:
- Multinational Pharma Companies: Holding patent families covering similar compounds or formulations.
- Local Innovators: Developing alternative therapies or improved compounds.
- Patent Citations: Prior art references encompass patents and publications from global filings (e.g., US, EPO, PCT) similar in structure or intended use.
Notable trends:
- Incremental Innovation: Focused on modifications improving bioavailability, stability, or manufacturing processes.
- Secondary Patents: Covering formulations, dosage forms, or methods of use.
- Challenges and Litigation: Active patent challenges, particularly in follow-on markets dealing with minor modifications.
Positioning of BR112015024869 in the Patent Landscape
This patent likely claims specific compounds or therapeutic methods, potentially overlapping with international patents but tailored to the Brazilian legal environment. Its strategic importance lies in:
- Establishing initial patent protection for novel molecules or formulations in Brazil.
- Serving as a basis for subsequent patent filings or licensing.
- Acting as a barrier to generic entry, especially if the claims cover key active ingredients.
Legal and Commercial Implications
- Patent Validity and Enforceability: Dependent on adherence to procedural requirements, prior art novelty, and inventive step standards.
- Infringement Risks: Generic manufacturers may attempt to design around the claims or challenge validity through post-grant procedures.
- Market Exclusivity: The patent affords exclusivity possibly until 2035, depending on prosecution and maintenance.
Strategic Consideration: Patent owners should consider securing patent families in corresponding jurisdictions for comprehensive protection.
Conclusion
Brazilian patent BR112015024869 constitutes a targeted, well-defined intellectual property asset essential in defending a pharmaceutical innovation within Brazil. Its scope hinges on chemically specific claims, with claims strategically balanced between broad coverage and detailed refinement to withstand legal scrutiny. The patent fits within a competitive landscape characterized by incremental innovations, supplemental protection strategies, and active patent enforcement by industry and legal entities.
Key Takeaways
- The patent’s scope focuses on specific chemical compounds and their therapeutic uses, with claims carefully structured to balance breadth and enforceability.
- Its positioning within Brazil’s evolving patent landscape reflects strategic efforts to maintain market exclusivity amid increasing generic challenge potential.
- Comprehensive understanding of claims is crucial for assessing infringement risks and patent strength.

FAQs
1. How does the scope of BR112015024869 compare to international patents?
It is tailored for the Brazilian market, focusing on specific compounds or uses, but may have counterparts in other jurisdictions with broader claims, if filed through international patent procedures.
2. What strategies can competitors employ to work around this patent?
They may develop chemically distinct derivatives outside the scope of claims, or challenge the patent’s validity based on prior art or lack of inventive step.
3. How long will this patent remain enforceable in Brazil?
Assuming maintenance fees are paid and no invalidation occurs, it is valid until approximately 2035, considering Brazil’s 20-year patent term from filing.
4. What are the primary risks associated with patent infringement in Brazil?
Risks include infringement lawsuits, injunctions, and damages. Conversely, patent invalidation or challenges could nullify the patent’s enforceability.
5. How important are patent claims in defining market exclusivity?
Claims definitively delineate the scope of exclusivity; broader claims enhance market control, whereas narrow claims require precise positioning but minimize vulnerability.
