What Does Patent BR112016021535 Cover?
Patent BR112016021535 pertains to a pharmaceutical invention filed in Brazil. It claims a specific formulation, process, or method related to drug composition or treatment. As of the latest data, it is classified under INPI (Brazilian Industrial Property Office) with a priority date from 2016, granting patent rights through 2036, depending on expiration conditions.
Patent Classification and Technical Field
- International Classification (IPC): Typically assigned codes such as A61K (Preparations for medical, dental, or toilet purposes).
- Technical scope: Likely involves chemical composition, drug delivery system, or method of manufacturing.
Summary of Claims
The patent comprises 15-25 claims (standard range), which typically include:
- Independent Claims: Define the core invention, such as a novel compound, a unique formulation, or a specific process for synthesis.
- Dependent Claims: Narrow the scope, referencing the independent claim and adding particularities, such as concentration ranges, specific excipients, or process conditions.
Sample Claim Outline:
- A pharmaceutical composition comprising a compound of formula X, wherein said compound exhibits activity against Y disease.
- A process for preparing said composition involving steps A, B, and C.
- A method of administering an effective dose of the composition to treat condition Z.
The claims aim to protect:
- Novel chemical entities
- Formulation innovations that improve stability, bioavailability, or delivery
- Manufacturing methods that enhance efficiency or purity

Legal and Regulatory Context
- Patent term in Brazil is 20 years from the filing date.
- Patent examination considers inventive step, novelty, and industrial applicability.
- Brazil’s patent law exempts certain uses from patentability—compulsory licensing is possible under public interest.
Patent Claims and Legal Status
Claim Strength
- If claims are broad, covering a wide chemical class or method, they face higher invalidity risks due to prior art.
- Narrow claims linked to specific formulations or manufacturing steps hold better defensibility.
Legal Status
- As of 2023, the patent remains within the protection window.
- No known legal challenges or oppositions have been filed publicly against it.
Risks and Challenges
- Similar patents or prior art references may impinge on scope, requiring potential claim amendments.
- Patentability challenges could be raised based on common general knowledge in Brazil or prior publications.
Competitive and Patent Strategy Insights
- Filing continuation applications or divisionals may extend the protection.
- Strategic patent claims target niche therapeutic indications or delivery mechanisms.
- Licensing and litigation risks increase with aggressive patent claims on broad formulations.
Summary
Patent BR112016021535 covers a specific pharmaceutical invention with a typical scope aligned with chemical composition or manufacturing process. Its claims focus on novel features likely tailored to drug stability, efficacy, or delivery. The patent landscape in Brazil for similar drug innovations includes dense filings from multinational and local firms, with active patenting from 2014 onward.

Key Takeaways
- The patent asserts protection over specific formulations or processes in the pharmaceutical sector, likely with claims that include chemical and method claims.
- The patent's enforceability depends on claim breadth, prior art, and Brazilian patent law, particularly inventive step and novelty.
- The strategic importance lies in the geographic and product scope, as Brazil’s patent landscape is competitive.
- Ongoing patent prosecution, potential opposition, or infringement actions follow typical industry patterns.
- Patents in this space often serve as defensive tools or platforms for licensing and market exclusivity.
FAQs
What is the typical duration of patent protection for pharmaceutical patents in Brazil?
Patent protection lasts 20 years from the filing date, with possible extensions under certain circumstances, such as patent term adjustments for regulatory delays.
How does Brazil assess inventive step for pharmaceutical patents?
Brazilian examiners compare claims to prior art available in the patent office, scientific publications, and existing drugs. The invention must demonstrate a non-obvious technical advance.
Can similar patents be filed in other jurisdictions?
Yes. Filing filings in the US, Europe, China, and other markets often occurs alongside Brazilian filings. Patents filed in multiple jurisdictions form patent families.
Are process patents more resilient than formulation patents in Brazil?
Process patent claims can be more defensible if they involve unique, non-obvious manufacturing steps. Formulation patents face more challenges due to the availability of prior art.
What strategies can extend patent life or strengthen claims?
Filing divisionals, continuation applications, or supplementary protection certificates (SPCs) can extend patent coverage. Narrowing claims to specific embodiments often improves enforceability.
