    • Potential Anticipated Claim(s) (under 35 U.S.C. § 102): Extremely relevant due to common assignee and shared priority. This patent specifically addresses non-invasive optical measurements of blood constituents. Differentiation for US11160455 would likely rely on very specific structural features of the wearable device (e.g., arrangement of sources/detectors on arcs for different placements like teeth), the explicit "plurality of semiconductor sources" generating a "plurality of optical wavelengths" in particular ranges for specific physiological parameters (glucose, ketones, HbA1c), and the described SNR enhancement techniques and full smartphone/cloud integration.

    • Publication/Filing Date: Granted August 20, 2019 (Filed Nov 12, 2018)
    • Brief Description: This patent, assigned to Omni Medsci Inc. (the same assignee as US11160455), describes non-invasive multi-wavelength devices for analyzing tissue. It is a continuation of several earlier applications, including US15/855,201 and US16/004,154, suggesting a common lineage with US11160455.
    • Potential Anticipated Claim(s) (under 35 U.S.C. § 102): Highly relevant due to common assignee and continuation chain. This patent broadly covers non-invasive multi-wavelength tissue analysis. Claims in US11160455 would need to distinguish themselves by the specific application to blood measurements in tissue, the precise wearable form factors (teeth, wrist, ear), and the detailed methods of SNR enhancement and specific data processing/cloud integration.

    • Full Citation: US10517484 B2
    • Publication/Filing Date: Granted December 31, 2019 (Filed Oct 23, 2018)
    • Brief Description: This patent, assigned to Omni Medsci Inc. (the same assignee as US11160455), describes a multi-wavelength wearable device for non-invasive measurements in tissue. It is a continuation of US15/711,907 and is very similar in title and scope to US11160455.
    • Potential Anticipated Claim(s) (under 35 U.S.C. § 102): Extremely relevant. Given the almost identical title and common assignee, this patent is likely a direct parent or sibling application that covers very similar subject matter. Differentiation for US11160455 would depend on very narrow distinctions in claim language, such as specific combinations of light sources (e.g., LED type, number, or arrangement on arcs), detection system configurations, or the explicit details of the SNR enhancement methodologies not found in US10517484. As a co-pending or parent application, it would be considered prior art only if its effective filing date (or that of its priority chain) predates the earliest claimed invention date of US11160455 and it was published before US11160455's effective filing date. Otherwise, it may be subject to common ownership exceptions or obviousness-type double patenting considerations.

The numerous citations by the same assignee (Omni Medsci Inc.) and references to continuation applications highlight a family of patents related to non-invasive optical measurements in tissue. These family members are often the most relevant prior art, potentially anticipating or rendering obvious various aspects of the claimed invention, depending on their specific disclosures and relative priority dates. The distinctions for US11160455 likely lie in the precise combination of a wearable device adapted for specific locations (teeth, wrist, ear), using a plurality of semiconductor sources to generate multiple optical wavelengths, with a detection system configured for SNR enhancement (e.g., by increasing intensity or comparing on/off signals), and integration with a smartphone/tablet and cloud for comprehensive data management and processing.
