VAHALA, and MAX OSKAR KOHLER Appeal 2015-008298 Application 13/515,519 Technology Center 3700 Before: JEFFREY A. STEPHENS, ERIC C. JESCHKE, and BRENT M. DOUGAL, Administrative Patent Judges. DOUGAL, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134(a) from a rejection of claims 1—12, 14—16, and 18—20. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Appeal 2015-008298 Application 13/515,519 CLAIMED SUBJECT MATTER The claims are directed to high intensity focused ultrasound (HIFU) transducer optimization. Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. A therapy planning tool that facilitates magnetic resonance (MR) guided high intensity focused ultrasonic (HIFU) ablation planning, including: a processor that executes computer-executable instructions for optimizing HIFU transducer element transmission, the instructions comprising: evaluating transducer data including transducer element position, geometry, and acoustic parameter information; evaluating 3D MR data including ROI data describing a size, shape, and position of a region of interest (ROI) to be ablated, and obstruction data describing a size, shape, and position of an obstruction between one or more of a plurality of HIFU transducer elements and the ROI; executing an optimizer that determines an optimal waveform that maximizes HIFU waveform delivery to the ROI while minimizing HIFU waveform delivery to the obstruction and surrounding tissue, wherein the optimal waveform is determined such that the optimal waveform is continuously applied to the HIFU transducer elements during an ablation procedure; and a memory that stores the computer-executable instructions, the transducer data, MR data, and a plurality of optimized HIFU parameters. 2 Appeal 2015-008298 Application 13/515,519 REJECTIONS1 Claims 1—12, 14—16, and 20 are rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement. Claims 1—12, 14—16, and 18—20 are rejected under 35 U.S.C. § 101, for being directed to an abstract idea. OPINION 35 U.S.C. §112 The Examiner finds that “the language ‘waveform is continuously applied by the HIFU transducer elements during an ablation procedure’” in claims 1 and 10 “was not described in the specification in such a way as to” comply with the written description requirement. Final Act. 3. Appellants argue that: the originally filed specification discloses “that there is no direct element shutoff but rather optimal amplitudes and phases applied to all transducer elements.” .... [T]he therapy planning tool determines optimal amplitudes and phases so that there is no need for the tool to be turned off. Appeal Br. 4 (citing Spec. p. 6,11. 1—5, p. 9,11. 6—8). Thus, “[tjhose skilled in the art would surely understand that if there is no element shutoff, then the ‘optimal waveform is continuously applied,’ as recited in claim 1. That is, if the elements are not shutoff, the waveform is being continuously applied.” Id. at 5. Appellants also highlight the contrast in the Specification “between embodiments where elements are shutoff and do not receive any applied 1 The rejections under 35 U.S.C. § 102 and 103 were withdrawn in the Advisory Action. Adv. Act. 2. 3 Appeal 2015-008298 Application 13/515,519 waveform and the embodiments where elements are not shutoff.” Id. at 6. In particular, Appellants point to the embodiment of Figures 6—8, where transducer elements are shut off if they don’t have “an unimpeded line of sight to the ROI” (region of interest). Id. (citing Spec. 7,11. 17—19). It is argued that “[t]his contrast further illustrates that the original specification conveys ‘with reasonable clarity’ to those skilled in the art that the Appellants were in possession of ‘the optimal waveform is continuously applied to the HIFU transducer elements during an ablation procedure.’” Id. The Examiner responds that “lack of a direct element shutoff does not foreclose the likelihood that for one or more elements of the HIFU transducer the optimal amplitude would simply be zero, which is effectively a shutoff of the element.” Ans. 5; see also id. at 5—7. Appellants reply “that claim 1 recites that the optimal waveform is applied continuously, without requiring a particular amplitude or phase value for the waveform.” Reply Br. 3. Appellants continue “one of ordinary skill in the art would reasonably conclude that the optimal waveform is applied continuously when the transducer elements are not shut off, without requiring a particular amplitude or phase value for the optimal waveform.” Id. at 4. Appellants’ response does not directly address whether one of skill in the art would understand that an optimized waveform for one of the transducer elements with a zero value would be continuously applied or if the element would be shut off. As such, Appellants have not shown error in the Examiner’s finding that “the language ‘waveform is continuously applied by the HIFU transducer elements during an ablation procedure’” in 4 Appeal 2015-008298 Application 13/515,519 claims 1 and 10 was “not described in the specification in such a way as to” comply with the written description requirement. Final Act. 3. 35 U.S.C. §101 The Examiner determines that the claims “are directed to a mathematical algorithm, which is an abstract idea,” i.e., non-statutory subject matter. Ans. 3. The Supreme Court has set forth “a framework for distinguishing patents that claim laws of nature, natural phenomena, and abstract ideas from those that claim patent-eligible applications of those concepts.” Alice Corp. v. CLS Bank Inti, 134 S. Ct. 2347, 2355 (2014) (citing Mayo Collaborative Servs. v. Prometheus Labs., Inc., 132 S. Ct. 1289, 1294 (2012)). Under that framework, we first “determine whether the claims at issue are directed to one of those patent-ineligible concepts”—i.e., a law of nature, a natural phenomenon, or an abstract idea. Id. (citing Mayo, 132 S. Ct. at 1296—97). If so, we must secondly “consider the elements of each claim both individually and ‘as an ordered combination’ to determine whether the additional elements ‘transform the nature of the claim’ into a patent-eligible application.” Id. (quoting Mayo, 132 S. Ct. at 1298, 1297). Under the first step of the Alice framework, the Examiner finds that: “These limitations read on a mathematical algorithm because they are understood in light of the specification to involve a ‘stochastic simulation algorithm’. . . , an ‘approximation algorithm’. . . , an ‘estimation algorithm’ . . . , ‘geometric []segmentation’. . . , and operation of an ‘optimization module or function.’” Ans. 3 (citations to the Spec, omitted). 5 Appeal 2015-008298 Application 13/515,519 Under the first step, our reviewing courts “have found it sufficient to compare claims at issue to those claims already found to be directed to an abstract idea.” Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1334 (Fed. Cir. 2016). The claims at issue here are directed to manipulating existing information—using algorithms—to generate additional information, which are similar to other claims the courts have found to be ineligible under § 101. See Parker v. Flook, 437 U.S. 584, 585, 594—96 (1978) (rejecting as ineligible claims directed to (1) measuring the current value for a variable in a catalytic conversion process, (2) using an algorithm to calculate an updated “alarm-limit value” for that variable, and (3) updating the limit with the new value); Gottschalkv. Benson, 409 U.S. 63, 71—72 (1972) (rejecting as ineligible claims directed to an algorithm for converting binary-coded decimal numerals into pure binary form); Elec. Power Grp., LLC v. Alstom S.A., 830 F.3d 1350, 1353—54 (Fed. Cir. 2016) (discussing how “collecting information” and “analyzing information by steps people go through in their minds, or by mathematical algorithms, without more” are abstract ideas); Digitech Image Techs., LLC v. Elecs. for Imaging, Inc., 758 F.3d 1344, 1351 (Fed. Cir. 2014) (“Without additional limitations, a process that employs mathematical algorithms to manipulate existing information to generate additional information is not patent eligible.”); see also Intellectual Ventures ILLCv. Capital One Fin. Corp., 850 F.3d 1332, 1339-40 (Fed. Cir. 2017) (determining that a claim reciting “an apparatus for manipulating XML documents” was directed to an abstract idea). Appellants argue that independent claim 1 is more than an algorithm because “[t]he claim addresses issues of continuous application of optimized HIFU transducer element properties by exploiting intercostal space in the 6 Appeal 2015-008298 Application 13/515,519 patient as an ablation path, specific to MR-guided HIFU procedure planners.” Reply. Br. 8. Though this shows what Appellants are attempting to do with their process, Appellants’ argument does not show that the claims are directed to anything more than “a process that qualifies as an ‘abstract idea’ for which computers are invoked merely as a tool.” Enfish, 822 F.3d at 1336. Under the second step, the Examiner finds that “[t]he independent claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception.” Ans. 3. The Examiner reasons that: 1. “the recited processor . . . and the recited memory ... are standard data processing structures that are entirely conventional in the art,” 2. “the recited field of use limitations ... do not provide for concrete application of optimized results of the algorithm that are simply bare numbers,” 3. “the recited presenting and receiving steps . . . serve simply to gather and provide data as input variables of the mathematical algorithm, and” 4. “the recited storage steps ... do not provide for concrete application of algorithm results.” Ans. 3^4. Appellants argue that “the claims at issue do not merely recite an abstract idea and add the words ‘apply if” because “independent claim 1 recites more than a generic computer.” Reply Br. 10. In support of this argument, Appellants repeat the entire language of claim 1. Id. 7 Appeal 2015-008298 Application 13/515,519 Merely repeating the language of the claim 1 does not show how the claim is directed to “significantly more than the judicial exception.” Nor does it address any of the specific findings of the Examiner. In particular, Appellants do not address the Examiner’s finding that “the recited processor . . . and the recited memory ... are standard data processing structures that are entirely conventional in the art, as is evident from Liu (patent publication US 20080200806) (see 120, 114 in FIG. 1, step 420 in FIG. 4, H 0050, 0053, 0059, 0060).” Ans. 3^4. Thus, we are not informed of error in the Examiner’s rejection. Next, Appellants argue “that the claims amount to ‘significantly more’ than the alleged abstract ideas of a known ‘mathematical algorithm’ [, bjecause the claims solve a technological problem in conventional industry practice and recite improvements to the functioning of a computer via improved processor performance for” optimizing a waveform. Reply Br. 10. However, Appellants do not identify any actual “improvements to the functioning of a computer.” Rather, Appellants’ method of optimizing a waveform is done by executing an optimizer after evaluating certain data sets (i.e., the evaluated data is run through an algorithm using a generic processor). Appellants further argue that “the features recited in claim 1 provide improvements in the fields of MR-guided HIFU therapy planning systems, HIFU waveform calculation methods, and computation methods for MR- guided ablation systems.” Id. at 12. In support, Appellants again merely repeat the text of the claim. Id. Thus, Appellants’ argument does not inform us of error in the Examiner’s rejection. 8 Appeal 2015-008298 Application 13/515,519 For these reasons, we sustain the Examiner’s decision rejecting claims 1—12, 14—16, and 18—20 as being directed to non-statutory subject matter. DECISION The Examiner’s rejections of claims 1—12, 14—16, and 18—20 are affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R. § 1.136(a)(l)(iv).
