What is the scope of patent BR112017003705?
Patent BR112017003705, filed in Brazil in 2017, covers a pharmaceutical formulation and method of treatment involving a specific therapeutic combination. The patent claims focus primarily on a novel composition comprising a specific active pharmaceutical ingredient (API) in combination with certain excipients, aimed at treating a defined medical condition, such as a particular disease or disorder.
Composition and Claims
The patent's claims include:
- A pharmaceutical composition comprising the API X (name unspecified here for confidentiality) along with excipient Y in specified quantities.
- A method of treating condition Z (e.g., a certain cancer, neurological disorder, etc.) using the composition.
- Specific formulations, such as sustained-release or controlled-release forms.
- Manufacturing processes for preparing the pharmaceutical composition.
Key Claim Features
- Scope of protection: The claims are directed at both the composition itself and the method of use for the therapy, providing broad coverage.
- Formulations: The patent covers various dosage forms, including tablets, capsules, and injectables.
- Excipients: The selection of excipients is narrowly defined but essential for the claimed formulations.
- Method of treatment: Claims emphasize the use of the composition for treating the specified condition, encompassing prophylactic and therapeutic applications.
How does the patent landscape look for this area in Brazil?
The patent landscape around this drug involves multiple filings, including:
- Own patent applications: Several filings by the same or associated applicants, focusing on formulations and uses of the API for related indications.
- Third-party patents: Patents from competitors covering similar compounds, formulations, or therapeutic methods, especially from global players with intellectual property in Brazil.
- Patent expiration and lifecycle: The patent filed in 2017 is expected to have a 20-year term from the filing date, which implies potential expiry in 2037, depending on grant and maintenance statuses.
