JP6067226 is a patent focused on a pharmaceutical composition or method, likely involving a specific compound, its formulation, uses, or a process improving existing therapies.
Scope of the Patent
The scope of JP6067226 is primarily delineated through its claims, which define the legal boundaries of the invention. While the full claims text is essential, without access to the complete document, a typical scope analysis involves:
-
Core Subject Matter:
The patent appears to cover a chemical entity or class of compounds with therapeutic properties, possibly related to a specific disease indication such as oncology, neurology, or metabolic disorders. Alternatively, it might protect a formulation or preparation method.
-
Protection of Novelty and Inventive Step:
The patent likely claims a novel compound, an improved synthesis method, or a unique pharmaceutical formulation not previously disclosed.
-
Method of Use vs. Composition:
The claims can encompass both the novel compound/formulation and its application (e.g., treatment of specific conditions), broadening the scope of protection.
In the context of Japanese patent law, particularly Article 29(1) of the Japan Patent Law, the scope is defined by the claims, which must be sufficiently clear and supported by the description.
Analysis of Key Claims
Given typical patent structures, JP6067226 probably includes:
Independent Claims
-
Chemical compound(s):
Broad claims covering the core chemical entity, including specific substituents, stereochemistry, or derivatives. These are often the strongest part of the patent.
-
Method of preparation:
Claims possibly detail a process for synthesizing the compound, emphasizing steps that provide a technical advantage or efficiency.
-
Pharmaceutical composition:
Claims may describe formulations combining the compound with carriers or excipients, optimized for stability or bioavailability.
-
Therapeutic use:
Claims could specify using the compound or composition for treating a particular disease or condition, which enhances scope by covering patentable uses.
Dependent Claims
-
Specific embodiments:
Narrower claims refine the independent claims, covering particular chemical variants or specific dosage forms.
-
Combination claims:
Claims covering combinatorial therapies, synergistic combinations, or specific delivery methods.
Claim Language and Interpretation
- The breadth of the claims controls scope; broad claims cover more ground but face higher invalidity risks, particularly if prior art is close.
- Narrow claims provide more defensible protection but could limit commercial coverage.
