HOFF, ELENI MANTIS MERCADER, and JAMES R. HUGHES, Administrative Patent Judges. HOFF, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellant appeals under 35 U.S.C. § 134 from a Final Rejection of claims 1–20. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Appellant’s invention is a framework for overlaying findings on medical image data. The framework extracts one or more findings from a radiology report, and detects one or more anatomical landmarks in image data corresponding to the radiology report. The one or more extracted 1 Appellants state that the real party in interest is Siemens Medical Solutions USA, Inc. Appeal Br. 4. Appeal 2020-003588 Application 15/413,486 2 findings are then correlated to, and overlaid with, the one or more detected anatomical landmarks on the image data. Spec. ¶ 7. Claim 1 is reproduced below: 1. One or more non-transitory computer readable media embodying a program of instructions executable by machine to perform operations for processing image data, the operations comprising: extracting one or more findings from a radiology report by performing a Natural Language Processing technique, wherein the one or more extracted findings are represented as one or more tuples; assigning, using a processor performing a machine learning technique, one or more weights to the one or more extracted findings in accordance with importance or severity; detecting one or more anatomical landmarks in the image data corresponding to the radiology report, wherein the one or more anatomical landmarks are one or more anatomically meaningful points; correlating the one or more tuples to the one or more anatomical landmarks; and overlaying only the one or more extracted findings assigned with the one or more weights that are above a predetermined threshold with the correlated one or more anatomical landmarks on the image data, wherein the one or more extracted findings are positioned at the correlated one or more anatomical landmarks on the image data. The prior art relied upon by the Examiner as evidence is: Name Reference Date Qian US 2014/0149407 A1 May 29, 2014 Ishii US 2014/0323858 A1 Oct. 30, 2014 Parthasarathy US 2015/0324523 A1 Nov. 12, 2015 Liu US 2016/0328643 A1 Nov. 10, 2016 Claims 1, 2, 4–8, 11–13, 17, 19, and 20 stand rejected under 35 U.S.C. § 103 as being unpatentable over Parthasarathy and Ishii. Appeal 2020-003588 Application 15/413,486 3 Claims 3, 9, 10, and 18 stand rejected under 35 U.S.C. § 103 as being unpatentable over Parthasarathy, Ishii, and Qian. Claims 14–16 stand rejected under 35 U.S.C. § 103 as being unpatentable over Parthasarathy, Ishii, and Liu. Throughout this decision, we make reference to the Appeal Brief (“Appeal Br.,” filed Oct. 15, 2016) and the Examiner’s Answer (“Ans.,” mailed Dec. 12, 2019) for their respective details. ISSUES 1. Does the combination of Parthasarathy and Ishii teach or suggest extracting one or more findings from a radiology report, wherein the one or more extracted findings are represented as one or more tuples? 2. Does the combination of Parthasarathy and Ishii teach or suggest assigning one or more weights to the one or more extracted findings in accordance with importance or severity? 3. Does the combination of Parthasarathy and Ishii teach or suggest detecting one or more landmarks in the image data corresponding to the radiology report? 4. Does the combination of Parthasarathy and Ishii teach or suggest overlaying extracted findings assigned with one or more weights that are above a predetermined threshold with the correlated one or more anatomical landmarks on the image data? ANALYSIS Claims 1, 2, 4–8, 11–13, 17, 19, and 20 Independent claim 1 recites extracting one or more findings from a radiology report, wherein the one or more extracted findings are represented as one or more tuples. See Appeal Br. 21 (Claim App.). Independent claims Appeal 2020-003588 Application 15/413,486 4 1, 5, and 19 each recite assigning one or more weights to the one or more extracted findings in accordance with importance or severity. See Appeal Br. 21–23, 26–27 (Claim App.). Independent claims 1, 5, and 19 recite detecting one or more anatomical landmarks in image data, the anatomical landmarks being anatomically meaningful points. Id. Independent claims 1, 5, and 19 each recite overlaying the extracted findings that are assigned weights above a predetermined threshold with the correlated anatomical landmarks. Id. Representing findings as tuples Appellant first argues that Parthasarathy describes detecting radiological findings but “does not teach or suggest representing such findings as tuples.” Appeal Br. 13. We are not persuaded by Appellant’s argument. Appellant’s Specification defines a tuple as “an ordered list of elements including, but not limited to, anatomical, disease and/or pathological terms, possibly together with modifiers.” Spec. ¶ 31. We agree with the Examiner’s finding that Parthasarathy teaches that “medical ontologies containing comprehensive medical terms . . . are utilized. The ontologies are integrated into a NLP [(Natural Language Processing)] to extract medical terms from narrative reports. . . . [T]he grading device automatically checks whether there are occurrences of anatomical terms and measurements (size, shape and extent) in the surrounding text.” Parthasarathy ¶ 31. We further agree with the Examiner’s finding that Parthasarathy’s teaching of such medical findings in text form corresponds to the claimed tuples. Ans. 17. Weights in accordance with importance or severity Appellant next contends that Parthasarathy evaluates the severity of findings, but does not assign one or more weights to the extracted findings Appeal 2020-003588 Application 15/413,486 5 based on such severity. Appeal Br. 14. Appellant asserts that Parthasarathy is only concerned with determining how much a medical report contributes to the current clinical problem. Id., citing Parthasarathy ¶ 32. We are not persuaded by Appellant’s arguments. As noted supra, we find that Parthasarathy uses natural language processing to extract medical terms from narrative reports. Parthasarathy ¶ 31. Parthasarathy further teaches “evaluat[ing] the severity of the findings. Findings like cancer, carcinoma, invasive, and the like are reported to referrals. If those findings are present in a medical report, the system can check whether follow up action are [sic] also present.” Id. We therefore agree with the Examiner that Parthasarathy teaches a system in which certain findings are assigned greater “importance,” which we equate to the claimed “weights.” Ans. 17-18. Detecting anatomical landmarks Appellant argues that Parthasarathy fails to teach detecting one or more anatomical landmarks that are anatomically meaningful points. Appeal Br. 14–15. Appellant’s contention is not persuasive of error because the teachings of Parthasarathy, taken together, correspond to this claim limitation. As noted by Appellant, imaging system 16 generates image data of a patient obtained using an image diagnosis apparatus. Appeal Br. 14. System 16 includes display devices 42 and a user interface 44 to adjust image reconstruction and acquisition parameters and/or for displaying generated image data to clinicians. Parthasarathy ¶ 20; Ans. 18. Parthasarathy further teaches a medical report containing “precise anatomical location, size, extent, shape of the findings.” Parasarathy ¶ 31. We further observe that Ishii teaches a medical imaging system in which relevant findings are visually correlated with anatomical locations. Appeal 2020-003588 Application 15/413,486 6 Ishii Figs. 3, 4. We agree with the Examiner’s finding that, taken together, these sections of Parthasarathy teach detecting one or more anatomically meaningful points of a patient. Ans. 18. We also determine that the combined teachings of Parthasarathy and Ishii suggest detecting one or more anatomically meaningful points of a patient. Overlaying sufficiently important findings with anatomical landmarks Appellant argues that the Examiner erred in relying on Ishii for a teaching of “overlaying only the extracted findings assigned with the one or more weights that are above a predetermined threshold with the correlated one or more anatomical landmarks on the image data.” Appeal Br. 15–16. We do not agree with Appellant, and we agree with the Examiner’s finding that Ishii teaches superimposing and displaying an annotation generated by annotation generation unit 22 on an anatomical image to indicate the target plaque position on the image. Ans. 19; Ishii ¶ 27, Figs. 3, 4. We further agree with the Examiner that combining the teachings of Parthasarathy, in which certain findings “like cancer, carcinoma, invasive, and the like are reported to referrals” because of their noted severity, with the teachings of Ishii concerning annotating images with extracted findings, would have resulted in the claimed invention. Ans. 19. Hindsight reconstruction Last, Appellant argues that the Examiner has not provided sufficient reason why the skilled artisan would combine Parthasarathy and Ishii. Appeal Br. 17. Appellant alleges that there is no evidence or suggestion in either reference to produce the claimed configuration. Appeal Br. 18. We do not agree with Appellant. We agree with the Examiner’s finding that Parthasarathy and Ishii reside in similar endeavors of medical imaging. Ans. Appeal 2020-003588 Application 15/413,486 7 20. We determine that the Examiner has stated a rationale, to “improve medical image diagnostic (sic) by annotating the image including superimposing a stress value color map on a plaque map,” having a rational underpinning to support the legal conclusion of obviousness. Final Act. 4; Ans. 20. Additionally, although a Reply Brief is not required, Appellant did not file a Reply Brief and failed to address the Examiner’s clarified findings and additional discussion of Parthasarathy and Ishii and the disputed limitations of claim 1, or otherwise rebut the findings and responsive arguments made by the Examiner in the Answer. See Ans. 17–20. Accordingly, based on a preponderance of the evidence, we find that the combination of Parthasarathy and Ishii teaches or suggests all the limitations of the invention recited in independent claims 1, 5, and 19. Thus, we sustain the Examiner’s § 103 rejection of claims 1, 2, 4–8, 11–13, 17, 19, and 20. Claims 3, 9, 10, and 18 Appellant does not separately argue for the patentability of claims 3, 9, 10, and 18, relying instead on the arguments made for independent claims 1 and 5. We conclude supra that the Examiner did not err in rejecting those independent claims. We therefore sustain the Examiner’s § 103 rejection of claims 3, 9, 10, and 18 over Parthasarathy, Ishii, and Qian, for the reasons given supra with respect to the § 103 rejection of claims 1 and 5. Claims 14–16 Appellant does not separately argue for the patentability of claims 14– 16, relying instead on the arguments made for independent claim 5. We conclude supra that the Examiner did not err in rejecting independent claim Appeal 2020-003588 Application 15/413,486 8 5. We therefore sustain the Examiner’s § 103 rejection of claims 14–16 over Parthasarathy, Ishii, and Liu, for the reasons given supra with respect to the § 103 rejection of claim 5. CONCLUSIONS 1. The combination of Parthasarathy and Ishii teaches extracting one or more findings from a radiology report, wherein the one or more extracted findings are represented as one or more tuples. 2. The combination of Parthasarathy and Ishii teaches assigning one or more weights to the one or more extracted findings in accordance with importance or severity. 3. The combination of Parthasarathy and Ishii teaches detecting one or more landmarks in the image data corresponding to the radiology report. 4. The combination of Parthasarathy and Ishii teaches overlaying extracted findings assigned with one or more weights that are above a predetermined threshold with the correlated one or more anatomical landmarks on the image data.
