Office Action

§103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on 09/10/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Objections Claim 13 is objected to because of the following informalities: claim 13 recites that the diagnostic tool comprises a converter that converts “at least one of alternating current to direct current and alternating current to direct current.” The phrase “alternating current to direct current” is duplicated, which results in a clerical inconsistency. This error is considered an informality and does not raise an issue of indefiniteness under 35 U.S.C. 112(b), as the intended scope of the claim is readily understood in view of the specification, which discloses conversion between alternating current and direct current in either direction. Appropriate correction is required. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Southwell et al. (U.S. 2016/0235981 A1) in view of Darr (U.S. 2007/0194942 A1). Regarding claim 1, Southwell et al. disclose in Figs. 1-3, a device (100), comprising: an electrical power source (300)(see [0105] an internal battery power source (300) supplying electrical energy to the device); an illumination component (136) electrically connected to the electrical power source (300)(see [0099] LEDs electrically connected to the internal power source (300) for status and operation indication); a first test lead (222) electrically connected to the electrical power source (300) and capable of being electrically connected to a first terminal of an external electrical component (Under BRI, electrode connectors and lead wires disclosed by Southwell et al. are electrical leads capable of being connected to an external component terminal, see [0251]); a second test lead (232) electrically connected to the electrical power source (300) and capable of being electrically connected to a second terminal of the external electrical component (see [0251] multiple electrode leads connected to the power source (300) and attachable to an external body or component); and a switch (190) positioned between the electrical power source (300) and at least one of the first test lead (222) and the second test lead (232) and movable between a first position and a second position (see [0182] & [0194]) to permit current from the electrical power source (300) to flow through the at least one of the first test lead (222) and the second test lead (232)(see [0251] user-actuated switch (190)es and control circuitry selectively enabling current flow from the battery to the output electrodes). Southwell et al. fail to disclose that the device is used as a diagnostic tool for energizing and testing an external electrical component distinct from a stimulation load. Darr et al. disclose in Figs. 1-2 & [0024] using a portable electrically powered test device with leads and a switch (190) to selectively energize and diagnose external electrical components (see [0025] & [0033]). It would have been obvious to one skilled in the art, prior to the effective filing date, to modify Southwell et al. by incorporating the use of the electrically powered device with test leads and a switch (190) for energizing and diagnosing an external electrical component as taught by Darr et al., as doing so would provide the ability to selectively energize and evaluate the operability of external electrical components using a portable power source because Darr et al. emphasize in paragraphs [0019] and [0030] that applying controlled electrical power through test leads and a user-actuated switch (190) enables efficient diagnostic testing of external electrical components without reliance on the native system power, thereby improving troubleshooting accuracy and safety. Regarding claim 2, Southwell et al. & Darr et al. disclose the device of claim 1, wherein Southwell et al. further disclose an output voltage of the device (380) is adjustable to match an operating voltage of the external electrical component (see [0113] adjustable output voltage levels controlled by internal circuitry and user settings, see [0114]). Regarding claim 3, Southwell et al. & Darr et al. disclose the device of claim 1, wherein Southwell et al. further disclose the switch (190) is positioned between a terminal of the electrical power source (300) and a terminal of the illumination component (136)(see [0112]; switching circuitry between the battery and LED indicators).

Regarding claim 13, Southwell et al. & Darr et al. disclose the method of claim 8, wherein Southwell et al. further disclose the diagnostic tool comprises a converter (via DCA see [0108]; wherein internal power conditioning and conversion circuitry used to convert supplied power into operational form for output delivery, under BRI, such power conditioning constitutes conversion between current forms). Regarding claim 14, Southwell et al. disclose a system, comprising: a power source (300) (see [0105] an internal battery power source (300) supplying electrical energy to the device); a first test lead (222) electrically connectable to the power source (300) and to a first terminal of an external electrical component (see [0251], electrode leads electrically connected to the power source (300) and attachable to an external body or component, under BRI, electrode leads correspond to test leads); a second test lead (232) electrically connectable to the power source (300) and to a second terminal of the external electrical component (see [0251] multiple electrode leads connected to the power source (300) and attachable to an external body or component); and a diagnostic tool, comprising: a switch (190) positioned between the power source (300) and at least one of the first test lead (222) and the second test lead (232) and movable between a first position and a second position (see [0182] & [0194]) to permit current from the power source (300) to flow through the external electrical component (see [0251] user-actuated switches and control circuitry selectively enabling current flow from the battery to the output electrodes). Southwell et al. fail to disclose the system being used to energize and test non-stimulation external electrical components. Darr et al. disclose a portable electrical testing system using a power source (300), leads, and a switch (190) to energize external electrical components for diagnostic purposes (see [0019], [0023] & [0031]). It would have been obvious to one skilled in the art, prior to the effective filing date, to modify the system of Southwell et al. by incorporating the system-level diagnostic configuration for energizing an external electrical component as taught by Darr et al., as doing so would provide a portable system capable of supplying electrical power through test leads to an external electrical component for diagnostic purposes because Darr et al. emphasize in paragraphs [0019], [0023], and [0031] that a system including a power source (300), test leads, and a switch (190) enables controlled energization and functional verification of external electrical components, thereby enhancing system versatility and diagnostic effectiveness.
