Patent Overview and Context
Filed in 2017 and granted in 2020, patent BR112017019809 covers a novel drug formulation or method of use designed to improve therapeutic efficacy, stability, or delivery. Brazil’s patent system follows the norms of the TRIPS agreement, emphasizing novelty, inventive step, and industrial applicability.
Prior to delving into the specific claims, it is vital to identify the patent’s classification. This patent falls within Class A61K (Medical preparations; Hand or surgical instruments; Sterilising; Preventing, diagnosing, treating, or alleviating disease) and possibly includes subclasses relevant to the active pharmaceutical ingredient or specific formulation techniques.
Scope of the Patent
The scope of BR112017019809 encompasses formulations, methods, and possibly uses of a pharmaceutical composition. It is directed toward:
- Novel Compositions: The patent’s scope likely covers specific combinations of active ingredients with excipients or carriers optimized for efficacy.
- Manufacturing Processes: Claims may extend to processes of synthesis, formulation, or stabilization of the drug.
- Methods of Use: Therapeutic indications or specific methods for administering the formulation, especially if targeting a particular disease condition.
Unlike broad, foundational patents, which encompass a wide range of compounds or methods, this patent’s scope appears to be more targeted toward specific formulations or methods developed by the applicant, potentially aiming to establish an effective, stable, or innovative drug delivery system.
Claims Analysis
Claim Concentration and Hierarchy:
The patent's claims structure is pivotal, comprising independent claims that define the broadest scope, followed by dependent claims that specify particular embodiments or features.
Typical Features of the Claims in BR112017019809:
-
Active Ingredient or Compound Claims:
Claims specify a particular active pharmaceutical ingredient (API) or a pharmacologically active compound. These may include chemical structure claims, such as specific stereoisomers or derivatives.
-
Formulation Claims:
Claims describing the composition as comprising specific excipients, stabilizers, or delivery agents, designed for enhanced bioavailability or stability.
-
Method Claims:
Claims cover treatment methods involving administering the drug formulation, possibly with particular dosages, routes, or treatment regimens.
-
Manufacturing Claims:
Claims may detail unique synthesis or formulation steps, providing protection for specific manufacturing protocols.
Claim Language and Limitations:
Brazilian patent claims tend to be precise, limiting scope to what is explicitly disclosed and supported. The claims may specify parameters such as concentrations, pH ranges, or particle sizes to delineate inventive features.
Notable Features of the Claims:
- The core independent claim likely encompasses a "pharmaceutical composition comprising [specific active ingredient] with [certain excipients] for use in treating [particular disease]."
- Dependent claims refine the scope by adding specifications, such as dosage forms (e.g., oral tablets, injectables) or specific process steps.
