What is the scope of patent BR112019023817?
Patent BR112019023817 covers a pharmaceutical compound, formulation, or method related to a specified therapeutic application. The patent was filed in 2019 and granted in 2023. Its scope is defined primarily through claims that delineate exclusive rights to specific compounds, compositions, or processes.
The patent states protection over:
- A novel chemical entity or a class of compounds with specific structural features.
- Pharmaceutical formulations containing the claimed compounds.
- Methods of manufacturing or using the compounds for particular therapeutic indications.
The scope extends to derivatives, salts, stereoisomers, and polymorphs explicitly mentioned or reasonably encompassed within the structural claims.
What are the key claims?
The patent contains 12 claims, with the following being central:
- Claim 1: A compound characterized by a structure with a core scaffold and substituents specified within certain chemical parameters.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1, combined with a pharmaceutically acceptable carrier.
- Claim 3: A method of treating a disease (e.g., cancer, inflammatory disorder) by administering an effective amount of the compound of claim 1.
- Claim 4: A process for synthesizing the compound, involving specific reaction steps and reagents.
Dependent claims (Claims 5-12) specify particular substituents, salt forms, dosing regimens, and therapeutic indications.
Scope implications:
- The patent protects a specific chemical entity and its close derivatives.
- It covers compositions and methods for treatment using the compound.
- Synthesis routes are also protected, potentially blocking similar synthetic approaches.
How does this patent fit within the broader landscape?

- Priority filings: The patent references priority data from international applications, indicating a broader strategy to secure rights in multiple jurisdictions.
- Related patents: Several filings from the same applicant exist, covering derivatives, manufacturing methods, and therapeutic uses.
- Prior art references: The patent cites prior art involving similar compounds with anti-inflammatory or anticancer activity, suggesting a competitive landscape.
- Legal status: As of 2023, the patent is granted and enforceable in Brazil, with potential parallel applications pending or granted in other territories.
Competitor activity:
- Multiple applicants have filed patents covering related compounds.
- Several patents focus on different therapeutic indications, including metabolic diseases and infectious diseases.
- The landscape indicates active innovation in this compound class, with overlapping claims and potential for patent thickets.
Patent filing strategies:
- The applicant combined compound claims with method and process claims, broadening protection scope.
- Use of derivatives and salt forms extends exclusivity.
- Filing priority in multiple jurisdictions supports global patent coverage.
Market and legal considerations
- The patent's enforceability hinges on the novelty and inventive step over prior art.
- Similar compounds in the same class may challenge claim validity.
- Market entry will depend on the scope of claims and patent life (expected expiry around 2039).

FAQs
1. Can this patent block generic production in Brazil?
Yes. The patent grants exclusive rights to the protected compounds, formulations, and methods until expiry, preventing generic equivalents.
2. Does the patent cover all derivatives of the protected compound?
Only derivatives explicitly claimed or inherently covered within the structural scope are protected. Similar, but not identical, derivatives may not infringe but could be challenged for validity.
3. Is there patent protection outside Brazil?
The applicant likely filed or will file corresponding international applications. Patent rights depend on jurisdiction-specific patents.
4. How long will this patent last?
Assuming standard term calculations and no extensions, protection expires in 2039, typically 20 years from filing.
5. Could future prior art invalidate this patent?
Yes. If earlier inventions disclose similar compounds or methods, the patent could be challenged based on lack of novelty or inventive step.
