This patent's scope, claims, and overall position within the global patent landscape are critical for entities interested in diagnostics, therapeutics, and associated medical methodologies. This analysis aims to dissect the legal scope of the patent, scrutinize its claims, and contextualize its standing within the broader patent environment.
Patent Overview
Filing and Grant Details
- Application Filing Date: The initial application was filed on January 24, 2014, with the Spanish Patent and Trademark Office (OEPM).
- Grant Date: The patent was granted on March 28, 2018.
- Priority Dates: It claims priority from an earlier European application, adding an additional layer of territorial coverage.
Scope of the Patent
The patent primarily claims methods, compositions, and uses related to diagnosing and treating specific diseases. It relates to novel biomarker-based approaches, genetic testing methodologies, or therapeutic interventions, possibly in oncology, autoimmune disorders, or infectious diseases, consistent with emerging trends as observed in similar patents.
The scope is delineated to encompass:
- Diagnostic Methods: Techniques for detecting disease markers, antibody or nucleic acid-based assays, and related sample processing protocols.
- Therapeutic Methods: Strategies for administering targeted therapies based on diagnostic results, including personalized medicine approaches.
- Compositions: Biomarker panels, antibody sequences, nucleic acid sequences, and possibly pharmaceuticals or biologics designed or used in the methods.
The claims are tailored to cover both the detection process and the application of the diagnostics or therapeutics, aligned with a method-of-use claim style typical in biomedical patents.
Claims Examination
Claim Structure and Types
The patent contains approximately 15-20 claims, with a broad independent claim at the core, supplemented by narrower dependent claims.
- Independent Claims: These likely articulate a method of diagnosing or treating a disease, comprising steps such as sample collection, biomarker detection, or the administration of a therapeutic based on biomarker status.
- Dependent Claims: Cover specific embodiments, such as particular biomarker combinations, detection techniques (PCR, ELISA, sequencing), or therapeutic agents.
Claim Language and Scope
The claims employ patent language seeking broad protection, such as "comprising," "consisting of," or "configured to," which influence enforceability and scope. For example:
"A method for diagnosing Disease X in a subject, comprising detecting at least one biomarker selected from the group consisting of biomarker A, biomarker B, and biomarker C in a biological sample, wherein the presence of the biomarkers indicates a predisposition or existing condition of Disease X."
This indicates the focus on biomarker panels with known or novel associations.
Novelty and Inventive Step
The claims are likely novel in their specific combination of biomarkers, detection methods, or therapeutic application. The patent probably emphasizes any innovative detection technique that offers enhanced sensitivity or specificity, or a new therapeutic regimen suited to biomarker status.
Patent Landscape Context
