CAPP, JILL D. HILL, and LEE L. STEPINA, Administrative Patent Judges. STEPINA, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant,1 Koninklijke Philipus N.v., appeals from the Examiner’s decision to reject claims 1, 4 and 7–21. Final Act. 1. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM-IN-PART and enter a new ground of rejection pursuant to 37 C.F.R. § 41.50(b). 1 We use the word “Appellant” to refer to “Applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as {{RPII}}. Appeal Br. 1. Appeal 2019-002258 Application 14/385,247 2 CLAIMED SUBJECT MATTER The claims are directed to an apparatus for making interpolated three- dimensional thermal dose estimates using magnetic resonance imaging. Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. A medical apparatus comprising: a magnetic resonance imaging system for acquiring magnetic resonance thermometry data from a subject, wherein the magnetic resonance imaging system comprises a magnet with an imagmg zone; a temperature control system operable for controlling the temperature within a target zone located within the imaging zone; a memory for storing machine executable instructions; a processor for controlling the medical apparatus, wherein execution of the machine executable instructions causes the processor to: acquire the magnetic resonance thermometry data from multiple slices within the imaging zone by controlling the magnetic resonance imaging system; interpolate a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data; receive a treatment plan; and control the temperature control system in accordance with the treatment plan to control the temperature within the target zone; wherein the instructions cause the processor to acquire at least part of the magnetic resonance thermometry data when controlling the temperature control system. Appeal Br. 17 (Claims App.). REFERENCE The prior art relied upon by the Examiner is: Ozeki US 4,674,046 June 16, 1987 Appeal 2019-002258 Application 14/385,247 3 Mougenot, C, Quantification of Near-Field Heating During volumentric MR-HIFU Ablation, Med. Phys. 38(1), January 2011 (hereinafter “Mougenot”). REJECTION Claims 1, 4, and 7–21 are rejected under 35 U.S.C. § 103(a) as unpatentable over Mougenot and Ozeki. OPINION Claim 1 The Examiner finds that Mougenot discloses most of the elements recited in claim 1, including an apparatus that uses magnetic resonance imaging to acquire thermometry data from multiple slices within an imaging zone, but Mougenot fails to disclose “interpolating a three dimensional thermal dose estimate.” Final Act. 2–3. To address this deficiency, the Examiner turns to Ozeki, finding this reference discloses “image processing including interpolating a three-dimensional data set from acquired multi- slice image data in order to obtain information between the slices which cannot be obtained by data acquisition of the parallel slices.” Id. at 3 (citing Ozeki 5:24–41). The Examiner reasons that it would have been obvious to one skilled in the art to have modified the apparatus disclosed by Mougenot to incorporate interpolation between slices in order to provide a more detailed thermal dose estimation. Id. Appellant argues that the Examiner erred in finding that Ozeki discloses “inte[r]polating a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data.” Appeal Br. 7. Appeal 2019-002258 Application 14/385,247 4 Appellant argues that, instead, Ozeki discloses linear interpolation of image data to generate an interpolated image. Id. The Examiner responds that Ozeki is cited only to teach interpolating a three-dimensional data set from acquired multi-slice image data in order to obtain information between the slices which cannot be obtained by data acquisition of the parallel slices. Ans. 5. Thus, according to the Examiner, Appellant’s assertion that the rejection relies on an incorrect finding of fact regarding Ozeki misinterprets the basis for the rejection set forth in the Final Office Action. Id. In reply, Appellant argues, “the Examiner has not cited any portion of Ozeki or Mougenot that discloses that the interpolation operation of Ozeki is applicable to the image acquisition operation of Mougenot,” and “the motivation to combine references must come from the references themselves (see MPEP §2143).” Reply Br. 3. Appellant’s arguments are unavailing. As the Examiner correctly notes, the rejection of claim 1 does not rely on Ozeki to teach interpolating a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data. Thus, Appellant’s argument that Ozeki does not teach this element does not address the rejection of claim 1. As for Appellant’s argument that the motivation to combine the references must come from the references themselves (see Reply Br. 8), this assertion appears to rely on an outdated interpretation of the teaching, suggestion, or motivation test. Contrary to Appellant’s contention, the Examiner’s obviousness rejection must be based on “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness” . . . . [H]owever, the analysis need not seek Appeal 2019-002258 Application 14/385,247 5 out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ. KSR Int’l. Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007) (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). The Examiner finds that Ozeki teaches image data processing including interpolation of three-dimensional data from acquired multi-slice image data to obtain information between slices that cannot be obtain by data acquisition of parallel slices. Final Act. 3. Appellant does not contest this finding. See Appeal Br. 7–9. The Examiner determines that, in light of this teaching in Ozeki, a person of ordinary skill in the art would have found it obvious to incorporate interpolation in the apparatus of Mougenot to obtain more detailed thermal dose estimates. Final Act. 3. Again, Appellant does not persuasively contest this conclusion. Accordingly, we sustain the rejection of claim 1 as unpatentable over Mougenot and Ozeki. Appellant next argues that the interpolation process carried out by the apparatus recited in claim 1 is complex. Appeal Br. 7–9. Specifically, Appellant states: The present application recognizes that interpolat[ing] a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data is a complex process that entails integrating two distinct transformations: (1) conversion of the magnetic resonance thermometry data to thermal dose data, and (2) spatial interpolation. How these two distinct transformations are integrated to (per claim 1) interpolate a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data is not obvious, nor is it made obvious by Ozeki’s linear interpolation of imaging data to generate an interpolated image. Appeal 2019-002258 Application 14/385,247 6 Id. at 8. We disagree with Appellant’s argument on this point because, as the Examiner correctly points out (Ans. 5), this argument is not commensurate with the scope of claim 1, which does not specify the two steps upon which Appellant’s argument is based. We have considered all of Appellant’s arguments in support of the patentability of claim 1, but find the Examiner has the better position. Accordingly, we sustain the rejection of claim 1. Claims 4, 7, 8, and 11–13 Appellant makes no separate arguments in support of claims 4, 7, 8, and 11–13. See Appeal Br. 7–16. Accordingly, these claims fall with claim 1, from which they depend. Claim 9 Claim 9 depends from claim 1 and requires that “the target zone has a border, wherein execution of the instructions further causes the processor to calculate a border thermal dose within a predetermined distance from at least a portion of the border.” Appeal Br. 18 (Claims App.). The Examiner finds that Figure 2 of Mougenot discloses the elements required by claim 9. Final Act. 3. Appellant contends that Figure 2 of Mougenot does not disclose instructions that cause a processor to perform a calculation as recited. Appeal Br. 9. The Examiner responds by finding “a target zone would inherently include a border and the thermal dose maps shown in figure 2 of Mougenot . . . inherently include a calculation of a border thermal dose within a Appeal 2019-002258 Application 14/385,247 7 predetermined distance from at least a portion of the border (figure 2).” Ans. 5. Appellant has the better position on this point because the Examiner does not adequately explain how Figure 2 of Mougenot discloses, explicitly or inherently, instructions that perform a calculation of thermal dose at a predetermined distance from a portion of a border. Assuming for the sake of argument that a border is an inherent element of the target zone, the mere fact that such a border exists does not mean that calculating a quantity (such as a thermal dose) within a predetermined distance of this inherent border will occur. We do not sustain the rejection of claim 9 as unpatentable over Mougenot and Ozeki. Claim 10 Claim 10 depends from claim 1 and requires that “the three dimensional thermal dose estimate is only calculated within a predetermined interpolation volume, wherein the interpolation volume comprises the treatment zone.” Appeal Br. 18 (Claims App.). The Examiner determines that, “in the absence of any showing of criticality or unexpected result, the location of the interpolation volume would have been obvious to yield predictable results.” Final Act. 3–4. We agree with Appellant (see Appeal Br. 10; Reply Br. 5) that the Examiner’s reasoning is inadequately supported, and, therefore, we reverse the Examiner’s rejection of claim 10 as unpatentable over Mougenot and Ozeki. Nonetheless, we determine that a person of ordinary skill in the art of ordinary skill in the art would have found it obvious to estimate a three- dimensional thermal dose within a predetermined volume that comprises the Appeal 2019-002258 Application 14/385,247 8 treatment zone because, by definition, the treatment zone is the intended target of the thermal energy. In other words, a person of ordinary skill in the art would have had good reason to determine the thermal dose delivered to the primary area of interest during treatment. As for limiting the three- dimensional thermal dose estimate to calculation only within the predetermined interpolation volume, a person of ordinary skill in the art would have found it obvious to limit calculations in order to conserve computational resources. In this regard, we note that claim 10 limits the term “predetermined interpolation volume” only by requiring it to comprise the treatment zone. See Appeal Br. 18 (Claims App.). Accordingly, for the reasons discussed above, we enter a NEW GROUND OF REJECTION of claim 10 as unpatentable over Mougenot and Ozeki. Claims 14–21 Independent claim 14 recites a computer readable medium with instructions that cause a processor to “interpolate a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data by linear interpolation of the magnetic resonance thermometry data followed by conversion of the interpolated magnetic resonance thermometry data to interpolated thermal dose data.” Appeal Br. 19 (Claims App.) (emphasis added). Independent claim 15 recites a method including the steps of “interpolating a three dimensional thermal dose estimate in accordance with the magnetic resonance thermometry data by conversion of the magnetic resonance thermometry data to thermal dose data followed by exponential interpolation of the thermal dose data.” Id. at 20. Appeal 2019-002258 Application 14/385,247 9 Claims 16–20 depend, directly or indirectly, from one of claims 14 and 15. Id. at 20–22. Claim 21 depends from claim 1 and recites similar functional language to that quoted above from claims 14 and 15, but with the two functions presented as alternatives. Id. at 22. With respect to claims 14 and 15, the Examiner finds “the specific interpolation process applied to the data would involve an obvious selection of known interpolation processes to achieve the optimum result.” Ans. 6. With respect to claim 21, the Examiner states, “in the absence of any showing of criticality or unexpected result, the specific manner in which the dose estimate is interpolated would have been a matter of design choice to achieve optimum results.” Final Act. 4. We agree with Appellant that the Examiner’s reasoning in the rejection of claims 14–21 is not supported by rational underpinnings. See Appeal Br. 10–12. The Examiner does not identify any teaching regarding the specific order of steps recited in claims 14, 15, and 21. Further, to the extent the Examiner’s rejection relies on design choice, Appellant’s Specification explains the effect the different sequences and types of interpolation/conversion have on the accuracy of the estimate obtained. See Spec. 19:8–21:28, Figs. 9–12. Thus, Appellant has shown error in the Examiner’s use of design choice to address the above-noted limitations. Accordingly, we do not sustain the rejection of claims 14–21 as unpatentable over Mougenot and Ozeki. DECISION The Examiner’s rejection is affirmed-in-part. Appeal 2019-002258 Application 14/385,247 10 More specifically, We affirm the rejection of claims 1, 4, 7, 8, and 11–13 as unpatentable over Mougenot and Ozeki. We reverse the rejection of claims 9, 10, and 14–21 as unpatentable over Mougenot and Ozeki. We enter a new ground of rejection of claim 10 as unpatentable over Mougenot and Ozeki.
