Scope and Claims Analysis
Patent Title and Abstract
The patent claims to a method for diagnosing or predicting susceptibility to diseases or disorders based on detecting specific genetic polymorphisms. It emphasizes identifying certain genetic markers associated with increased risk, thus enabling predictive medicine.
Claims Overview
The patent comprises multiple claims—primarily independent claims, supplemented by dependent claims, delving into specific genetic loci and detection methods. The claims focus on:
- Methodology: Biological sample collection, detection of specific genetic markers, and correlation with disease risk.
- Genetic Markers: SNPs (single nucleotide polymorphisms) associated with particular diseases or conditions.
- Detection Techniques: Genotyping, PCR-based methods, sequencing, hybridization, and other molecular techniques.
Key Independent Claims
- Claim 1: A method for predicting susceptibility to a specific disease, comprising detecting at least one genetic polymorphism in a subject's biological sample, wherein the polymorphism is associated with increased disease risk.
- Claim 2: The method of claim 1, wherein the detection involves amplifying the genetic region containing the polymorphism.
- Claim 3: The method of claim 1 or 2, wherein the polymorphism is a single nucleotide polymorphism (SNP) identified at a particular locus (e.g., specific chromosomal position).
Dependent Claims
Dependent claims detail specific embodiments, such as the use of particular detection methods (e.g., real-time PCR, hybridization probes), particular SNPs, and diseases (e.g., cardiovascular, metabolic, or neurodegenerative disorders).
Scope Summary:
- Focus on genetic detection of markers linked to disease susceptibility.
- Encompasses various detection technologies applicable to genotyping.
- Applies broadly to multiple diseases, provided the genetic markers are associated with increased risk.
- Includes both diagnostic and predictive uses, aligning with current personalized medicine trends.
Analysis of Claim Scope
The claims are structured to cover a broad range of genetic markers linked to various diseases, offering patent protection for methodologies that detect these markers. The broad language concerning the types of detection methods and diseases provides a strategic advantage, allowing different diagnostic labs and companies to utilize similar techniques without infringing, provided they avoid the specific claims or markers specified.
However, the existence of prior art—such as other gene-disease association patents and general detection techniques—may limit the scope of enforceability. The patent's novelty hinges on specific combinations of genetic markers and the particular use case in Japan.
Patent Landscape Context
