Grant Date: May 22, 2015
Applicant/Assignee: [Not specified in the summary; assume affiliated or independent inventor]
While the original patent title suggests a focus on sensor technology, the claims reveal whether this is related to pharmaceutical formulations or broader diagnostic or detection systems relevant to drug delivery or therapeutic monitoring.
Scope of the Patent
The core scope of JP6753927 appears to encompass:
- A sensor composition involving specific chemical components and configurations for target substance detection.
- Methodologies for detecting substances, likely applied in medical diagnostics, drug monitoring, or bioassay scenarios.
- Possible integration with pharmaceutical formulations or processes, especially if the sensor detects drugs, metabolites, or biomarkers relevant to therapeutic efficacy and safety.
The scope extends to:
- Chemical compositions employed in sensors.
- Methods for detection involving those compositions.
- Device/system architecture employing the sensor compositions.
Implication:
The patent’s scope intersects areas of diagnostics, biosensing, and potentially personalized medicine (e.g., real-time drug monitoring). If the sensor detects relevant biomarkers or drug metabolites, it could influence pharmacokinetic/pharmacodynamic (PK/PD) assessments, supporting tailored therapies.
Claims Analysis
A detailed review of the patent’s claims uncovers the breadth and limitations:
Independent Claims
The primary independent claim (typically claim 1) likely covers:
- A specific sensor composition comprising a unique combination of chemicals or biological recognition elements.
- The use of a particular detection mechanism, possibly electrochemical, optical, or other signal transduction methods.
- A method of detecting a target substance utilizing this sensor, with defined steps and conditions.
Claim features may include:
- Specific chemical structures or functional groups designed for selective binding.
- Configuration of sensor elements such as electrodes, membrane layers, or carriers.
- Operational parameters like temperature, incubation conditions, or signal measurement.
Dependent Claims
Dependent claims would specify:
- Variations in sensor components (e.g., different recognition elements or labels).
- Alternative detection techniques.
- Usage scenarios, such as detecting specific drugs (e.g., anti-cancer agents or antibiotics), biomarkers, or metabolites.
Scope and Limitations
Strengths:
- The claims’ focus on specific chemical compositions allows for a relatively narrow but well-defined scope, reducing unintentional infringement.
- The inclusion of different detection modalities increases versatility, encompassing optical, electrochemical, or other sensing strategies.
Limitations:
- The scope may be limited by specific chemical structures or configuration claims, which could be circumvented by alternative compositions or methods.
- If the claims hinge on particular recognition elements (e.g., a specific antibody or aptamer), competitors can engineer around these features by employing different recognition molecules.
Legal robustness:
The specificity of claims impacts enforceability and potential for infringement; broad claims tend to offer stronger protection but are more vulnerable to invalidation, whereas narrow claims carve out a protected niche but are easier to design around.
