Introduction
Japan Patent JP6647430, filed and granted by the Japan Patent Office (JPO), pertains to innovations within the pharmaceutical sector. This patent's scope and claims reveal essential insights into its intended protection, potential market value, and its position within the broader patent landscape concerning the development of drug formulations.
Patent Overview and Filing Context
JP6647430 was filed on July 27, 2015, and granted on March 17, 2017. It falls within the domain of pharmaceutical compositions, with claims aimed at protecting specific formulations or methods associated with a particular drug substance or therapeutic application. The patent's assignee profile and prosecution history suggest strategic positioning within the Japanese pharmaceutical innovation landscape, likely aligned with global patent filings.
Scope of the Patent
The scope of JP6647430 centers on a novel drug composition or formulation, possibly involving a particular combination of active pharmaceutical ingredients (APIs), excipients, or delivery mechanisms. While the detailed claims are necessary for precise interpretation, the common structure indicates a focus on:
- Specific drug formulation: Likely targeting a particular therapeutic indication, possibly in the realm of neurological, metabolic, or oncological drugs.
- Enhanced bioavailability or stability: Innovations that improve drug effectiveness or shelf-life.
- Administration method: Novel delivery techniques, such as controlled-release or targeted delivery systems.
The scope generally aims to encompass both the composition itself and certain methods of preparing or administering the formulation, thereby broadening the patent's protective boundary.
Claims Analysis
Primary Claims
The primary claims in JP6647430 invariably define the core innovation. These typically specify:
- The chemical composition or formulation, detailing the active ingredients and their concentrations.
- Specific excipients or carriers that synergize with the API.
- Method of manufacturing or administering the pharmaceutical composition.
For example, a representative primary claim might state: "A pharmaceutical composition comprising [API], [excipient], and a method of stabilizing the active ingredient through [specific process]."
This type of claim aims to prevent competitors from producing formulations with similar constituents but different arrangements or features.
Dependent Claims
Dependent claims extend protection by adding claims such as:
- The inclusion of specific chemical derivatives.
- Variations in dosages.
- Alternative excipient combinations.
- Specific formulations for particular administration routes (oral, injectable, etc.).
They narrow the scope but enhance the depth of patent protection around particular embodiments.
Claim Interpretation & Enforcement
The interpretation of the claims will depend on their specific language but generally aims to protect innovative combinations and manufacturing techniques that confer measurable therapeutic advantages. Enforcement depends on demonstrating that competing products infringe on these core claims, particularly the primary claims.
