Scope and Claims Analysis
Claims Overview
The claims of MX2010013152 articulate a method broadly designed for detecting a viral pathogen or a gene associated with a virus. The claims are characterized by several core features:
- Use of nucleic acid hybridization techniques with specific probes
- Amplification steps, including PCR-based methods
- Detection through labeled probes or indicators
- Application to various biological samples (e.g., blood, saliva, tissue)
- Optional steps for confirming the presence or absence of viral genetic material
Claim Breadth and Technical Specificity
1. Main Claim Scope
The primary claim establishes a method comprising contacting a biological sample with a specific nucleic acid probe designed to hybridize with viral genetic sequences, followed by detection of hybridization indicative of viral presence. Its breadth encompasses any virus for which appropriate probes are designed, rendering it adaptable to multiple pathogens.
2. Dependent Claims
Subsequent claims specify:
- The sequence or composition of the probes (e.g., oligonucleotides with defined sequences)
- Specific amplification protocols, including temperature conditions and primer design
- Use of certain detection labels (fluorescent, radioactive, enzymatic)
- Sample types and preparation techniques
This layered claim structure balances broad applicability with detailed procedural specifics, providing patent robustness while enabling various implementation strategies.
Scope Limitations
While the claims are broad in targeted viruses, they are constrained by:
- The reliance on specific nucleic acid sequences (which may limit scope to certain viruses)
- The technical steps involved (e.g., PCR amplification, hybridization, detection methods)
- The need for particular reagent compositions
The claims do not extend to viral detection methods utilizing wholly different principles, such as antigen tests or next-generation sequencing, thus carving out a precise niche centered on nucleic acid hybridization assays.
Patent Landscape Context
Regional Context
