US 8630699

US Patent 8630699, titled "Body worn physiological sensor device having a disposable electrode module," was issued on January 14, 2014, from an application filed on June 5, 2012. The original assignee is Welch Allyn Inc., with inventors Steven D. Baker, Eric T. McAdams, James P. Welch, Norbert Ohlenbusch, and Thomas P. Blackadar.

Abstract:
The patent describes a method for providing high voltage circuit protection for a patient monitor. This method involves providing a substrate that supports electrical connections to a patient's body. It further includes determining and printing a pattern and thickness of a first material with a specific resistivity, and then determining and printing a pattern and thickness of a second material with a different resistivity, such that at least part of the second material overlays the first material on the substrate.

Plain-language overview of independent claims:

Independent Claim 1:
This claim describes a body-worn patient monitoring device. It features at least one disposable module with multiple electrical connections to the patient's skin for measuring physiological signals. This disposable module has its own connector. The device also includes at least one power source (internal or external) and a communication-computation module. The communication-computation module has a connector to receive physiological signals from the disposable module. Crucially, this module contains a microprocessor for active patient monitoring and real-time physiological analysis, and a radio circuit for communicating raw signals or analysis results wirelessly at specific times or events to a remote receiver. The key aspect is that the disposable module is mechanically and electrically coupled directly to the communication-computation module, and the entire device (both modules) is directly, but non-permanently, affixed to the patient's skin.

Independent Claim 12:
This claim details a method for providing high-voltage circuit protection for a body-worn monitor. The method involves several steps:

1. Providing a substrate that holds one or more electrical connections to a patient's body.
2. Determining the print pattern and thickness for a first material, which has a specific resistivity, to be printed on the substrate.
3. Determining the print pattern and thickness for a second material, with a different resistivity, also to be printed on the substrate.
4. Printing the first material onto the substrate.
5. Printing the second material onto the substrate, with at least a portion of the second material overlapping the first material.

Independent Claim 17:
This claim outlines a body-worn patient monitoring device that includes a means for performing real-time physiological analysis of signals from a patient. It also includes a radio for communicating results of this analysis at predetermined times or events. The device further comprises a power management circuit designed to reduce power consumption by entering a "sleep mode" during periods when useful physiological data is not being acquired. The device exits this sleep mode to actively monitor the patient and perform analysis.

Independent Claim 18:
This claim describes a body-worn patient monitoring device having a first portion and a second portion. The first portion is disposable and includes at least one electrode for attachment to a patient's body, along with a power source. The second portion is reusable and detachably coupled to the first portion. This second portion includes a microprocessor for actively monitoring the patient and a radio circuit for wireless communication of physiological signals or analysis results. The entire device is configured to be directly, non-permanently affixed to the patient's body.

Regarding CAFC 2026 dockets for US patent 8630699, a search of recent CAFC dockets for 2026 did not specifically return any results for patent number 8630699. While there are several patent cases being heard or decided in the CAFC in 2026, none of the available summaries directly reference this specific patent number. Therefore, I do not have authoritative information regarding any active CAFC litigation for US8630699 at this time.
