Scope and Objectives of Patent JP6124411
JP6124411 addresses a novel method for producing pharmaceutical compositions, particularly focusing on enhancing drug stability, bioavailability, and manufacturing efficiency. The patent emphasizes a process utilizing specific components, conditions, or sequences that distinguish it from prior art, aiming to deliver improved therapeutic efficacy and manufacturing robustness.
Its scope likely encompasses:
- Methodologies for preparing pharmaceutical compositions involving specific chemical or biological agents.
- Process conditions such as temperature, pH, solvents, or mixing procedures.
- Formulation innovations that facilitate controlled release, improved stability, or targeted delivery.
This patent is positioned to protect proprietary manufacturing techniques rather than the active pharmaceutical ingredient (API) itself, aligning with Japan's trend toward process patents to guard against generic copycats.
Claims Analysis
A patent’s claims define its legal boundaries. Based on standard structure and available information, JP6124411's claims likely include:
1. Independent Claims
Scope:
- Cover a specific process for producing a pharmaceutical composition involving sequential steps or unique conditions.
- May specify the use of particular solvents, temperature ranges, or additive agents that influence drug stability or release characteristics.
Potential Claim Example:
"A method of producing a pharmaceutical composition comprising: dissolving an active ingredient in a specific solvent at a temperature within a defined range, followed by a drying step under controlled conditions to produce a stable formulation."
This type of claim provides broad protection for the overall process, ensuring that competitors cannot easily circumvent by minor modifications.
2. Dependent Claims
Scope:
- Further specify parameters such as:
- Types of active ingredients (e.g., small molecules, biologics).
- Specific conditions (e.g., pH, temperature, mixing times).
- Additional steps or components (e.g., encapsulation, excipients).
Purpose:
- Narrow protection to specific embodiments.
- Add fallback positions if the independent claims are challenged.
Claims Strategy & Innovation Aspects
- The focus on process rather than composition can extend patent term life by preventing generic manufacturing.
- The claims may encompass novel steps that address prior art limitations, such as improved stability or manufacturing yields.
Patent Landscape in Japan for Pharmaceutical Manufacturing
