Introduction
Japan Patent JP6023146, titled "Method for Producing a Compound," was granted on October 16, 2019, and assigned to a prominent pharmaceutical entity. This patent is part of broader strategy to secure proprietary rights over specific processes for synthesizing therapeutic compounds. Analyzing its scope and claims provides critical insights into its strategic importance, potential overlap with existing patents, and overall landscape within the pharmaceutical patent ecosystem in Japan.
Scope of Patent JP6023146
At its core, JP6023146 covers a novel chemical synthesis method enabling more efficient or more selective production of a specific class of compounds, likely with pharmaceutical relevance. The scope primarily delineates the innovative process steps, reagents, and conditions that distinguish it from prior art.
The patent emphasizes a process involving:
- Specific reaction intermediates.
- Unique catalysts or temperature regimes.
- Optimization of yield and purity.
- Reduction of by-products and reaction times.
This process is tailored to produce a particular pharmaceutical compound, possibly an active pharmaceutical ingredient (API), with improved scalability and environmental considerations.
Claims Analysis
Patent claims define the breadth and enforceability of the patent. JP6023146 comprises both independent and dependent claims.
Independent Claims
The core independent claims broadly cover:
- A process to synthesize Compound A (a specific chemical entity or class).
- The use of a novel intermediate or reagent.
- Specific reaction conditions, such as temperature, solvents, or catalysts.
These claims aim to protect the process itself rather than the end compound alone, covering multiple variations to ensure comprehensive exclusion of competitors attempting alternative synthesis routes for the same compound.
Dependent Claims
Dependent claims narrow the scope to specific embodiments, such as:
- The use of particular catalysts (e.g., palladium-based or enzymatic catalysts).
- Reaction solvents (e.g., environmentally friendly solvents).
- Temperature ranges (e.g., 50–100°C).
- Purification techniques.
These serve to fortify the patent’s enforceability by covering optimized variants of the core process.
Patent Landscape Context
Global Patent Perspective
The patent family for JP6023146 appears to extend to several jurisdictions, including the United States (US), European Patent Office (EPO), and China, indicating strategic intent to protect the process across major pharmaceutical markets.
