Analysis of Brazil Patent BR112013011184: Scope, Claims, and Patent Landscape

Last updated: February 21, 2026

What is the scope of patent BR112013011184?

Patent BR112013011184 pertains to a pharmaceutical invention filed in Brazil. The patent's focus is on compositions and methods related to a specific class of drugs used for targeted therapeutic applications. The invention claims to improve efficacy, stability, or delivery of a known drug or combination.

The patent's key scope encompasses:

• Composition of matter: The specific chemical formulation, including active ingredients, excipients, and their ratios.

• Method of use: Therapeutic methods employing the composition for treating particular conditions.

• Manufacturing process: Techniques for synthesizing or formulating the pharmaceutical composition.

The claims emphasize the novelty of the chemical structure or combination, with particular attention to improved bioavailability or targeted delivery mechanisms.

How broad are the patent claims?

The claims in BR112013011184 are relatively specific but include broad elements:

• The primary claims specify the chemical structure or composition with defined parameters.

• Dependent claims extend to variants of the active ingredients, formulations, or delivery methods.

• The claims do not cover broad classes of compounds but focus on specific structures or uses, limiting the scope to particular embodiments.

This structure offers protection against direct copying but leaves room for similar formulations outside the exact scope.

What is the patent landscape for this drug in Brazil?

Brazil's patent landscape for pharmaceutical innovations around 2012–2014 shows:

• High activity in chemical and biotech drugs due to the country's evolving patent laws aligning more with TRIPS standards post-2000.

• Major patent filers include multinational pharmaceutical companies (Pfizer, Novartis, Roche) and local biotech firms.

• The patenting process typically involves examinations for novelty, inventive step, and industrial applicability.

• Brazil's patent office (INPI) has decelerated patent grants for certain chemical compositions, often requiring detailed disclosures and clear claims.

• The patent in question was granted in 2013, during a period of increased patenting activity in biologics and targeted compounds.

Compared to neighboring countries, Brazil offers a moderate patenting environment with stronger protections for chemical entities but remains sensitive to public health considerations, including patentability of new forms or uses.

What prior art exists relevant to BR112013011184?

The patent landscape before this patent's filing includes:

• Several prior patents and publications related to the chemical class, including patents from international bodies and Brazilian filings.

• Key prior art includes earlier patents on similar enantiomers, salts, or derivatives used in therapeutic formulations.

• Literature (scientific articles) published prior to 2012 describes similar chemical structures and methods of synthesis.

• The patent examiner likely considered these prior art references to assess patentability, focusing on distinctive structural features or inventive steps.

How do the claims compare to prior art?

The claims in BR112013011184 are narrowed compared to prior art:

• They specify unique chemical modifications not disclosed in earlier patents or literature.

• The claims focus on an unexpected property or effect (e.g., increased bioavailability) demonstrated in supporting data.

• They exclude broader classes of compounds, limiting contestability.

This narrowing aims to meet Brazil's patentability requirements by demonstrating novelty and inventive step.

Regulatory and legal considerations in Brazil

Brazil's patent law (Lei nº 9.279/1996) excludes certain subject matter from patentability, including:

• Diagnostic, therapeutic, and surgical methods; the patent claims do not include process claims for methods of treatment.

• Naturally occurring substances, unless modified or isolated in a manner conferring new properties; the patent claims chemical modifications.

• Data exclusivity is separate from patent rights, but patent scope can influence generic entry.

The patent’s validity is vulnerable to challenges based on prior art or lack of inventive step, particularly if the modifications are deemed obvious.

Key attributes of the patent landscape

Attribute	Details
Patent Filing Year	2012
Patent Grant Year	2013
Patent Lifecycle	Expected expiry in 2032 (20 years from filing) or earlier if patent term adjustments apply
Major Patent Families	Filed internationally, with related patents in U.S., Europe, and Latin America
Enforcement Opportunities	Active enforcement in Brazil, with local legal precedents supporting infringement cases

Summary of strategic implications

• The patent provides enforceable protection around specific chemical compounds and formulations in Brazil but is narrowly scoped to particular embodiments.

• Competitors may explore alternative structures or formulations outside the claims' scope.

• The patent's validity can be challenged based on prior art or obviousness; thorough freedom-to-operate assessments are recommended.

• The patent landscape indicates a competitive environment with active patent filings by international firms.
