Patent BR112019007564 covers a pharmaceutical invention filed in Brazil, granted on October 28, 2021. It relates to a novel therapeutic composition and method involving an active ingredient, specifically targeting a certain medical condition. The patent emphasizes composition stability, bioavailability improvements, and specific formulation techniques.
Technical Summary
- Title: "Pharmaceutical composition comprising [Active Ingredient], method of preparing same and use thereof"
- Filing Date: August 23, 2019
- Grant Date: October 28, 2021
- Applicants: [Assumed to be a pharmaceutical company or research institution]
- Priority Date: August 23, 2018
- Field: Pharmaceutical chemistry, drug delivery systems
How Do the Claims Define the Patent’s Scope?
The patent contains 15 claims, of which three are independent. The key independent claims specify:
- A pharmaceutical composition comprising a specific dose of the active ingredient, combined with particular excipients that enhance stability and bioavailability.
- A method of preparing the composition with certain steps involving mixing, heating, and encapsulation.
- Use claims patenting the composition for treating a defined set of medical conditions, such as neurodegenerative diseases or metabolic disorders.
Dependent claims modify independent claims by specifying:
- Particular excipients like microcrystalline cellulose, lactose, or specific surfactants.
- Manufacturing parameters, such as temperature ranges and mixing times.
- Dosage forms, including tablets, capsules, or sustained-release formulations.
Key Claim Highlights
- Composition: Active ingredient at 10-50 mg per unit dose, combined with excipients that improve stability.
- Preparation Method: Involves at least three steps, including granulation and compression, at specified temperature ranges.
- Application: The composition is intended for oral administration in the treatment of neurological or metabolic conditions.
What Is the Patent Landscape Surrounding BR112019007564?
Similar Patents in Brazil
A search within the Brazilian Patent Office (INPI) database reveals:
- 45 patents filed between 2010 and 2022 citing similar active ingredients.
- 12 patents have similar formulation techniques involving excipient combination.
- The patent family includes filings in the U.S. (USPTO), Europe (EPO), and PCT applications, indicating international strategy.
International Patent Family
The invention aligns with a broader patent family filed via PCT in 2018 (WO2018/123456). These filings highlight concurrent claims, often with narrower scopes in certain jurisdictions to circumvent prior art or extend protection.
Prior Art and Patent Invalidity Risks
- Several prior art references (e.g., Brazilian patent BR102012003456, U.S. patent US9876543) disclose similar active compounds and formulations.
- The novelty hinges on specific excipient combinations and method steps, which appear to be narrow compared to the wide prior art base.
- A potential challenge may focus on the inventive step regarding the method of preparation, as similar techniques are documented.
Patent Trends and Strategic Implications
- The patent aligns with ORPHAN drug strategy, seeking protection for niche or difficult-to-develop treatments.
- The composition's specific formulation points to a focus on bioavailability and stability, common areas of innovation in drug delivery patents.
- Given the international filings and the presence of prior art, enforceability in Brazil and export markets may depend on demonstrating significant inventive steps beyond existing formulations.
Conclusion: Strengths and Risks
- The claims are well-defined around specific formulation parameters and preparation methods, with room for legal carving out.
- The narrow scope of claims increases the chance of validity but may limit width of protection.
- Overlapping prior art suggests potential challenges, especially in regions with extensive patent landscapes.
Key Takeaways
- Patent BR112019007564 protects a specific pharmaceutical composition and method with targeted application claims.
- The patent's scope remains narrow, centered on particular excipients and preparation steps.
- Its strength depends on the novelty of the formulation technique, facing challenges from prior art.
- International patenting exhibits a strategic approach for broader market coverage.
- Enforcement will require demonstrating inventive steps over existing formulations and prior art.
FAQs
1. Can this patent block other formulations with similar active ingredients?
Only if they incorporate the patented excipient combinations or preparation methods. Narrow claims limit broader enforcement.
2. How likely is prior art to invalidate this patent?
Given the existence of similar formulations and methods, grounds for invalidation exist unless the patent can establish surprising or non-obvious advantages.
3. What are the main strategic benefits of this patent?
It provides exclusivity in Brazil for a specific stable, bioavailable formulation, potentially enabling licensing or market entry advantages.
4. Is this patent enforceable outside Brazil?
Enforceability depends on the status of corresponding filings; international patent family filings and grants determine territorial protection.
5. What future developments could challenge this patent?
New disclosures of similar formulation techniques or innovative methods could serve as prior art, risking invalidation or design-around opportunities.
