Scope of the Patent
Scope Summary:
JP2016526039 claims a novel manufacturing process for pharmaceutical compositions that enhances certain desirable properties such as yield, purity, stability, or bioavailability. The patent's scope is predominantly defined by the specific steps, reagents, temperatures, or conditions under which the composition is produced.
Key points:
- The scope is centered on a specific method involving a novel sequence or combination of processing steps.
- It may encompass intermediate product forms or final formulations generated via this method.
- The scope likely emphasizes improvement over prior art by addressing known issues like impurity formation, process efficiency, or compound stability during production.
Legal interpretation:
- The claims are method-based rather than product-based, which means the patent covers the process rather than the end product directly, allowing for broader protection against alternative manufacturing techniques.
Claims Analysis
The claims define the legal protection. Based on typical process patents in this area, the following is an outline of the probable scope of claims, although precise claim language requires access to the full patent text.
Typical features of the claims include:
-
Step-specific claims:
- For example, a process involving mixing active pharmaceutical ingredients (API) with excipients under specific conditions.
- Use of particular solvents, temperatures, or pH levels.
- Sequential addition or specific order of process steps.
-
Condition-dependent claims:
- For instance, claims may specify temperature ranges (e.g., "maintaining at 40°C ± 2°C") or durations (e.g., "stirring for 2 hours").
-
Material-specific claims:
- Including particular forms or derivatives of active ingredients that improve stability or bioavailability.
-
Result-oriented claims:
- Claiming the method resulting in a pharmaceutical composition with particular properties—such as improved dissolution rate, enhanced stability, or reduced impurities.
Claim strategies:
- The patent likely employs both independent and dependent claims, with independent claims establishing broad process coverage and dependent claims adding specific limitations or preferred embodiments.
Innovation aspects:
- Novelty may stem from unique combinations of process parameters, the use of unconventional solvents, or innovative steps that prevent degradation of sensitive compounds.
Potential claim limitations:
- The claims are probably constrained to specific process conditions, which leaves room for alternative manufacturing methods outside the scope.
