Office Action

§102
DETAILED ACTION 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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1, 14, and 24 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-4, 6, 8, 10-17, 19, 21, 23, and 24 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Hageman et al (US 2023/0166111) hereinafter Hageman. The applied reference has a common applicant with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement. Regarding claims 1 and 14, Hageman discloses a system for closed-loop therapy (Fig. 2), the system comprising: memory (memory 212) configured to store a first set of one or more parameters for a first set of one or more therapeutic electrical stimulation signals [0121]; and processing circuitry (processing circuitry 210) coupled to the memory ([0121] Processing circuitry 210 may control stimulation generation circuitry 202 according to therapy programs stored in memory 212) and configured to: determine one or more local field potential (LFP) measurements of an LFP ([0133] processing circuitry 210 may determine a plurality of LFP measurements of an LFP), wherein the LFP is of a first signal type that is intrinsically generated by a signal source within a brain of the patient ([0029] the LFP is intrinsically generated by a signal source within the brain of the patient); cause delivery of one or more electrical stimulation signals ([0184] processing circuitry may control stimulation generation circuitry 202 to deliver a plurality of electrical stimulation signals via the determined one or more electrodes (804)); determine one or more evoked signals that are evoked by delivery of respective ones of the one or more electrical stimulation signals ([0185] For respective ones of the plurality of electrical stimulation signals, the processing circuitry may determine respective evoked signals (806)), wherein the one or more evoked signals are of a second signal type that is different than the first signal type of the LFP ([0185] processing circuitry may determine respective ERNA signals such as those illustrated in FIGS. 7A and 7B); determine a second set of one or more parameters for a second set of one or more therapeutic electrical stimulation signals based on the one or more evoked signals having the second signal type and the one or more LFP measurements of the LFP having the first signal type ([0190] processing circuitry may determine at least one parameter for the therapeutic electrical stimulation signal based on the respective evoked signals (808); Examiner notes that the newly determined parameter in step 808 would also be determined based off of the measured LFPs since the electrode configuration used to deliver the stimulation was chosen based off of the measured LFPs), wherein the second set of one or more parameters are updates to the first set of one or more parameters ([0192] processing circuitry may be configured to determine parameters for the therapeutic electrical stimulation signal based on the determined parameters of the determined electrical stimulation signal); and cause delivery of the second set of the one or more therapeutic electrical stimulation signals ([0193] processing circuitry may be configured to control stimulation generation circuitry 202 to deliver the therapeutic electrical stimulation signal based on the determined at least one parameter).
