This patent is assigned to Roche Molecular Systems, Inc., and pertains to a novel pharmaceutical composition or method involving a specific biomolecule, likely related to diagnostics or therapeutic agents, considering Roche's portfolio. This analysis delineates the scope and claims of the '617 patent, examines its intended technological field, and contextualizes it within the broader patent landscape relevant to its focus area.
Scope of the '617 Patent
The scope of the '617 patent is primarily defined by its claims, which delineate the legal boundaries of the invention, and the specification, which provides detailed context. The patent generally pertains to a specific method or composition involving nucleic acid molecules and possibly certain analytical or diagnostic applications.
Field of Invention
According to the patent, the invention falls within the domain of molecular diagnostics, focusing on nucleic acid amplification, hybridization methods, or detection systems, which are emblematic of Roche's core competencies. The invention may involve novel oligonucleotide probes, primers, or methods for detecting target nucleic acids with high specificity and sensitivity.
Claims Overview
The patent encompasses multiple claims, with independent claims establishing broad inventive principles and dependent claims elaborating specific embodiments and variants. The scope covers:
- Biomolecular compositions, such as primers or probes specific to particular genetic sequences.
- Methodologies for detecting or quantifying nucleic acids, potentially including hybridization conditions, amplification techniques, or sample preparation procedures.
- Detection systems involving labeled molecules, hybridization substrates, or specific assay configurations.
Example of a typical independent claim (paraphrased):
"A method for detecting a target nucleic acid in a sample, comprising contacting the sample with a nucleic acid probe comprising a specific nucleotide sequence complementary to the target, under conditions conducive to hybridization, and detecting the hybridized probe."
While the exact wording varies, such claims aim to protect innovative diagnostic reactions involving specific sequences, reagents, or procedural steps.
Claim Breadth and Limitations
The claims tend to be carefully constructed to cover:
- Specific nucleotide sequences or motifs identified as unique or diagnostic.
- Chemical modifications on probes or primers, such as fluorescent labels, to enhance detection.
- Sample types and matrix variations, including blood, saliva, or other biological fluids.
- Assay configurations, such as real-time PCR or hybrid capture.
The scope's breadth appears to aim at covering both fundamental detection methods and their particular implementations—although, as with most patents, the claims are likely narrower in key respect to specific sequences or reagents to avoid prior art.
