Office Action

§101 §102 §103
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 . Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-15 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claim(s) recite(s) the mental concept/mathematical concept of setting with a processor a dithering range of a frequency for generating a stimulus and controlling the frequency to be changed. This judicial exception is not integrated into a practical application because the combination of additional elements (e.g. processor, claim 9 computer readable storage medium, and/or dependent claim 15 stimulation controller/generator, etc.) fails to integrate the judicial exception into a practical application. The generically recited computer elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer. In addition, the stimulation controller/generator only receives data and provides no therapy and is merely a nominal or token extra-solution component of the claim, and is nothing more than an attempt to generally link the product to a particular technological environment. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements when considered separately and in combination do not add significantly more to the exception. The additional limitation only process and retrieve data and these are well-understood, routine, conventional computer functions as recognized by the court decisions listed in MPEP 2106.05. The claims are directed to an abstract idea and/or the end result of the system/method, the essence of the whole, is a patent-ineligible concept. The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception because they amount to a general computer performing a calculation. The claims are directed to an abstract idea, i.e. implementing the idea of setting with a processor a dithering range of a frequency for generating a stimulus and controlling the frequency to be changed, such as may be done by a mental process, critical thinking, and/or paper and pencil, or done by a mathematical equation, with additional generic computer elements, or additional structure (e.g. processor, claim 9 computer readable storage medium, and/or dependent claim 15 stimulation controller/generator, etc.) recited at a high level of generality that perform generic functions routinely used in the art, and do not add a meaningful limitation to the abstract idea because they would be routine in any computer implementation or in the relevant art. Thus, the recited generic computer components perform no more than their basic computer functions. These additional elements are well‐understood, routine and conventional limitations (see cited document(s)) that amount to mere instructions or elements to implement the abstract idea. In addition, the end result of the system/method, the essence of the whole, is a patent-ineligible concept. See the recent decisions by the U.S. Supreme Court, including Alice Corp., Myriad, and Mayo. In addition, the current claims are similar to other recent court decisions dealing with analyzing, comparing, and/or displaying data, such as Electric Power Group, Digitech, Grams, and Classen. Based on the plain meaning of the words in the claim, the broadest reasonable interpretation of the claims (e.g. claim 10 having a processor, and corresponding method claim 1) is a system having a processor, wherein the processor is programmed with executable instructions to perform the calculations/mental process/critical thinking. The claims do not impose any limits on how the stimulation frequency information is received by the processor, and thus this step covers any and all possible ways in which this can be done, for instance by typing the information into the system, or by the system obtaining the information from another device. The claim also does not impose any limits on how the computations are accomplished, and thus it can be performed in any way known to those of ordinary skill in the art. The calculations are simple enough to be practically performed in the human mind or through critical thinking. Note that even if most humans would use a physical aid (e.g., pen and paper, a slide rule, or a calculator) to help them complete the recited calculation, the use of such physical aid does not negate the mental nature of this limitation. Nor does the recitation of a processor in the claim negate the mental nature of this limitation because the claim here merely uses the processor as a tool to perform the otherwise mental process. The processor is recited so generically (no details whatsoever are provided other than that they are a memory and processor) that they represent no more than mere instructions to apply the judicial exception on a computer. These limitations can also be viewed as nothing more than an attempt to generally link the use of the judicial exception to the technological environment of a computer. It should be noted that because the courts have made it clear that mere physicality or tangibility of an additional element or elements is not a relevant consideration in the eligibility analysis, the physical nature of these computer components does not affect this analysis. See MPEP 2106.05(I) for more information on this point, including explanations from judicial decisions including Alice Corp. Pty. Ltd. v. CLS Bank Int'l, 573 U.S. 208, 224-26 (2014). Although the processor or claim limitations may fall under several exceptions (e.g., a mathematical concept-type abstract idea or a mental process-type abstract idea), there are no bright lines between the types of exceptions. See, e.g., MPEP 2106.04(I). Thus, it is sufficient for the examiner to identify that the limitations align with at least one judicial exception, and to conduct further analysis based on that identification. The limitations of the claims are carried out by the processor. No element has been set forth to supply or receive the stimulation frequency information/signal, and the processor performs the necessary software tasks so that the result of the abstract mental process is just data/controlling the changing of the stimulation frequency. The stimulation controller/generator limitation represents extra-solution activity because it is a mere nominal or tangential addition to the claim. See MPEP 2106.05(g), discussing limitations that the Federal Circuit has considered to be insignificant extra-solution activity. Even when viewed in combination, the additional elements in this claim do no more than automate the mental processes (e.g., the mental computation of setting with a processor a dithering range of a frequency for generating a stimulus and controlling the frequency to be changed, etc.), using the computer components as a tool. While this type of automation may improve the life of a practitioner/physician (by minimizing or eliminating the need for mentally computing metrics), there is no change to the computers and other technology that are recited in the claim as automating the abstract ideas, and thus this claim cannot improve computer functionality or other technology. See, e.g., Trading Technologies Int’l v. IBG, Inc., 921 F.3d 1084, 1093 (Fed. Cir. 2019) (using a computer to provide a trader with more information to facilitate market trades improved the business process of market trading, but not the computer) and the cases discussed in MPEP 2106.05(a)(I), particularly FairWarning IP, LLC v. Iatric Sys., 839 F.3d 1089, 1095 (Fed. Cir. 2016) (accelerating a process of analyzing audit log data is not an improvement when the increased speed comes solely from the capabilities of a general-purpose computer) and Credit Acceptance Corp. v. Westlake Services, 859 F.3d 1044, 1055 (Fed. Cir. 2017) (using a generic computer to automate a process of applying to finance a purchase is not an improvement to the computer’s functionality). Accordingly, the claim as a whole does not integrate the recited judicial exception into a practical application and the claim is directed to the judicial exception. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-15 are rejected under 35 U.S.C. 102a1 as being anticipated by Hershey (2015/0217117). Hershey discloses a stimulation generation circuit (e.g. figure 3, element 58, para. 51, etc.) that is controlled by a processor or computer readable media (e.g. figure 3, element 48, para. 49, etc.) using an algorithm, such as a Bayesian algorithm, to vary the frequency of the delivered stimulation (i.e. stimulus characteristic setting unit, paras. 67-71, figures 7a-c, etc.) where the center frequency can be set (e.g. 2000 Hz, para. 71, etc.) and then a range of values around the frequency can be set (e.g. 500 Hz, para. 71, etc.; dithering range setting unit) automatically or manually/predetermined. The stimulation duration, length, form, inter-phase gap are also changed by the algorithm to get different frequencies (e.g. paras. 44, figures 7a-c showing different frequencies, etc.; stimulus characteristic setting unit). For claims 3 and 15, note that Hershey in paragraph 55 incorporates by reference the IPG structure as set forth in patent number 6516227 which includes a processor that turns on/off switches to generate the stimulation signal (e.g. figure 4a in incorporated document, etc. in the alternative, see the 103 rejection below). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 3 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Hershey. Hershey discloses the claimed invention using the processor to control the stimulation generation circuit and incorporates patent 6516227 showing the use of switches to deliver the stimulus. It would have been obvious to one having ordinary skill in the art at the time the invention was made/before it was effectively filed to have modified the system and method as taught by Hershey, with the processor changing an adjustment signal to turn on/off switches of the stimulation circuit to generate the stimulus, as is well known and common knowledge in the art (mpep 2144I, 2144.03), since it would provide the predictable results of providing a conventional switching matrix and/or FET switches to ensure the proper stimulation signal is delivered to the patient and at the proper time.
