Scope of Patent ES2565536
The scope of ES2565536 is defined primarily through its independent and dependent claims, along with descriptive specifications detailing its intended applications and technical boundaries. Overall, the patent claims a specific laboratory method for detecting genetic markers tied to disease susceptibility or progression, emphasizing its utility in clinical diagnosis.
Key Features of the Scope:
-
Methodology Based on Genetic Marker Detection:
The patent applies to laboratory techniques utilizing nucleic acid amplification (e.g., PCR) or hybridization techniques to identify particular DNA or RNA sequences linked to a disease.
-
Targeted Diseases and Genetic Markers:
While the patent is broadly applicable to various diseases, it focuses on genetic markers for diseases such as cancers, neurological disorders, or infectious diseases. The claims specify markers identified through sequencing or comparative genomic analysis.
-
Sample Analysis Conditions:
The scope covers methods involving biological samples (blood, tissue biopsies, saliva), prepared under specified conditions to ensure detection accuracy.
-
Detection of Mutations or Polymorphisms:
The claims emphasize the identification of mutations, single nucleotide polymorphisms (SNPs), or structural variants correlated with disease phenotypes.
-
Diagnostic kits and reagents:
In addition to methods, the patent extends to diagnostic reagents, probes, primers, or kits specifically designed for the claimed detection procedures.
Claims Analysis
The claims constitute the core legal enforceability of the patent, delineating the boundaries of protection awarded to the patent owner.
Independent Claims
The primary independent claim (e.g., Claim 1) appears to cover:
- A method for diagnosing a disease in a subject, comprising:
- Collecting a biological sample from the subject;
- Detecting the presence or absence of specific genetic markers linked to the disease, using a particular probe or amplification process;
- Interpreting the detection to determine disease susceptibility or progression.
This broad claim effectively covers any laboratory process using the specified genetic markers for diagnosis within the scope of the specified detection methods.
Dependent Claims
Dependent claims refine and specify the independent claims by including:
- Specific genetic markers or gene sequences (e.g., "SEQ ID NO:1, 2, or 3") associated with particular diseases.
- Particular detection techniques such as real-time PCR, hybridization with specific probes, or sequencing.
- Sample types, such as peripheral blood or tissue biopsies.
- The use of particular primers or probes.
Claim Scope and Limitations
The scope hinges on the novelty of the genetic markers and detection methods disclosed. Any alternative method or marker outside those explicitly claimed could potentially circumvent patent rights, unless claims are broad enough. The claims exclude detection methods not employing the specified genetic sequences or techniques, which restricts their breadth.
