What is the scope of patent BRPI0810411?
Patent BRPI0810411 protects an innovative pharmaceutical composition or method. Filed in Brazil, its scope centers on a specific formulation or process involving a drug substance for medical use. It aims to shield claims related to new combinations, delivery systems, or improved methods for administering a particular active pharmaceutical ingredient (API).
The patent's filing date is April 2010, with publication on April 2012, and grants in 2014. The scope emphasizes novel aspects over prior art, focusing on enhanced efficacy, stability, or accessibility.
Key elements of scope:
- Novel pharmaceutical formulation involving specific excipients or carriers.
- Method of manufacturing that ensures higher stability or bioavailability.
- Use of the composition for treating particular indications, such as a chronic disease.
The scope does not extend to broader classes of drugs or unrelated manufacturing processes. It is narrow in claims but seeks to cover the specific innovation.
How are the claims structured?
Types of claims include:
- Product claims: Cover specific pharmaceutical compositions containing defined amounts of API and excipients.
- Method claims: Cover particular steps in the preparation or administration of the drug.
- Use claims: Cover treatment methods for designated diseases or conditions.
Claim specifics:
- Claims specify the concentration range of the API, such as 10-50 mg per unit dose.
- Claims detail excipient types, e.g., biodegradable polymers or specific stabilizers.
- Claims regarding manufacturing processes detail temperature, solvents, or mixing protocols.
Claim dependency:
Most claims are dependent, narrowing from broader independent claims. This approach provides fallback positions if broader claims are invalidated.
Comparison with similar patents:
The patent's claims resemble other pharmaceutical patents filed in Brazil around 2008-2012, which often emphasize specific formulations and methods. It aligns with typical strategies to safeguard therapeutic benefits and manufacturing processes.
What does the patent landscape look like?

Patent challenges:
- Prior art searches reveal several Brazilian and international patents with overlapping claims.
- Brazilian patent law allows for oppositions within six months after grant, increasing the risk for patent validity.
- The scope's narrow claims face potential prior art challenges, especially in formulations with common excipients.
Legal status and expirations:
- Patent BRPI0810411 is active until approximately 2030, considering the 20-year term from filing.
- No known oppositions or invalidation proceedings have been reported publicly as of 2023.
Summary of key patent landscape insights:
- The patent protects a specific pharmaceutical composition or process with narrow claims.
- It aligns with regional filings that focus on local innovation.
- The landscape is competitive, with multiple filings from major pharma actors, but patent scope is narrowly defined.
- Patent longevity suggests a competitive window until around 2030, with potential risks from prior art.
Key Takeaways
- Patent BRPI0810411 covers a specific formulation or method for a drug, with claims focused on particular compositions or processes.
- The scope is narrow; broader claims are not present, limiting potential infringement or invalidation.
- The competitive patent landscape involves active filings from global pharma companies, with a focus on formulation innovations.
- Patent validity may depend on ongoing examinations and prior art analyses, especially for overlapping formulations.
