Claim 7 is rejected under 35 U.S.C. § 112, second paragraph, as indefinite.3 II. Claims 6–10 and 12 are rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement. III. Claims 6–10 and 12 are rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the enablement requirement. IV. Claims 1, 3, 4, 11, 12, and 21–23 are rejected under 35 U.S.C. § 103(a) as unpatentable over Sahni, Boernert, Sarvestani, Schellenberg, and Anderson. V. Claims 18 and 20 are rejected under 35 U.S.C. § 103(a) as unpatentable over Sahni, Sarvestani, Schellenberg, and Anderson. OPINION Rejection I–Indefiniteness Claim 7 depends from claim 6 and recites, The system according to claim 6, wherein the processor is further programmed to: monitor the user input devices to detect triggering of a user input device; and, in response to detecting 3 The Examiner withdrew a rejection of claims 1, 3, 4, 6–12, 18, and 20–23 as indefinite. See Final Act. 2; Ans. 4. Appeal 2020-001453 Application 14/408,342 4 triggering of the user input device, adjust the current position of the displayed real-time slice based on position of the triggered user input device. Appeal Br. 20 (Claims App.) (emphasis added). The Examiner determines “[c]laim 7 is indefinite because it is unclear from the specification and the claims how the current position of the real- time slice is adjusted.” Final Act. 2. We agree with Appellant that the language of claim 7 specifies that the adjustment is based on the position of the triggered user input device, and pages 2–3, 10, and 14–15 of the Specification adequately explain how this operation is performed. See Appeal Br. 8–9; Reply Br. 4–5; Spec. 2:1– 3:15, 10:10–17, 14:17–15:11. For example, the Specification states “[t]riggering the user input device (e.g., single clicking a button) associated with one of the light sources indicating the position of a slice selects the slice for manipulation,” and “once the slice is selected, the slice can be shifted and tilted by triggering a user input device on the other side of the line spanning between the light sources indicating the slice.” Spec. 14:28– 29, 15:7–9. Accordingly, we do not sustain the Examiner’s rejection of claim 7 as indefinite. Rejection II–Written Description Claims 6, 8–10, and 12 Claim 6 recites, in part, “at least one processor programmed to . . . generate a visual indication of the current position of the displayed real-time slice using the one or more visual indicators.”4 Appeal Br. 20 (Claims 4 Claims 8–10 appear to be rejected based solely on their dependency from claim 6. Final Act. 3–4. Appeal 2020-001453 Application 14/408,342 5 App.). The Examiner finds that Appellant’s Specification fails to provide support for this subject matter recited in claim 6, and, instead, merely suggests Appellant had possession of a desired result. Final Act. 3–4. The Examiner takes a similar position with respect to dependent claim 12. Id. The Examiner states, “the [S]pecification fails to provide a teaching to a skilled artisan how the algorithm of indicating is actually performed, and the disclosure essentially amounts to a black box.” Id. at 4 (emphasis added). Appellant asserts that pages 9 and 11 of the Specification explain the meaning of the term “real-time slice” as well as its location within the relevant coordinate frame. Appeal Br. 10. Appellant further asserts that real-time imaging in MR was known in the art. Id. (citing Spec. 1:5–7). In reply, the Examiner the states: Although Appellant discloses that the frame location and the slice location are known, Appellant entirely fails to disclose how the two locations are used or combined to display a visual indication of the current slice using the indicators on the frame. A skilled artisan is left to guess what if any possible ways Appellant intends to merge the two locations into a visual indication. Ans. 5. Thus, the Examiner takes issue with the requirement in claims 6 and 12 for a visual indication of the position of the real-time slice, not the recitation of a real-time slice per se. In reply, Appellant quotes the following language from the Specification, [T]he guidance module 64 further adjusts the light sources 80 [on the frame 78 of the user interface 76 of Fig. 5] to provide a visual indication as to position of the one or more slices of the real-time MR images displayed on the display device 74 positioned proximate to the subject 12. MR operators are used to identifying different slices by different color codes. Hence, it Appeal 2020-001453 Application 14/408,342 6 is advantageous to reuse this color coding to visualize the cross section of the slices. For each slice displayed, the corresponding light sources are set to the color coding the slice. Reply Br. 6 (quoting Spec. 14:17–22) (underlining omitted, emphasis added); see also Spec. 5:5–6, 10:18–22, 15:12–13, Fig. 8. We agree with Appellant that the cited portions of the Specification provide a specific example of color-coding as a method of providing a visual indication as recited in claims 6 and 12, which is adequate support for the feature with which the Examiner takes issue. Accordingly, we do not sustain the rejection of claims 6, 8–10, and 12 as failing to comply with the written description requirement. Claim 7 Claim 7 depends from claim 6 and recites, in part, “wherein the processor is further programmed to . . . adjust the current position of the displayed real-time slice.” Appeal Br. 20 (Claims App.). The Examiner finds that Appellant’s Specification fails to provide support for this additional subject matter of claim 7. In that regard, the Examiner finds the original disclosure fails to satisfy the written description requirement because, as the Examiner concluded with respect to claim 6, “the [S]pecification fails to provide a teaching to a skilled artisan how the algorithm of adjusting is actually performed, and the disclosure essentially amounts to a black box.” Final Act. 4. The Examiner finds that Appellant’s Specification merely suggests Appellant had possession of a desired result. See id. Appellant asserts that page 15 of the Specification provides adequate written description for claim 7. Ans. 10 (citing Spec. 15:1–17). Appeal 2020-001453 Application 14/408,342 7 Appellant has the better position because the example on page 15 of the Specification discusses the particular movements that may be performed to adjust the position of the real-time slice and what actions the user takes to trigger these movements. The Examiner does not explain adequately why more than this disclosure is required. Accordingly, we do not sustain the rejection of claim 7 as failing to comply with the written description requirement. Rejection III–Enablement Claims 6–10 and 12 The Examiner determines that independent claims 6, 7, and 12 each recites a system that performs the processes of indicating and adjusting a current position of a real-time slice of an image, but the specification fails to provide sufficient evidence to show enablement of the claimed subject matter. Final Act. 5. Specifically, the Examiner states, “Applicant has failed to adequately disclose the subject matter of Claim 6 that indicates the location on the frame which intersects the image slice.” Id. Appellant argues that Figures 4A–9 are specific working examples of the subject matter recited in claim 6, and pages 3 and 15 of the Specification provide further examples. Appeal Br. 11. Appellant also contends that the state of the prior art weighs in favor of finding no undue experimentation would be required to practice the claims. In response, the Examiner states, The issue is not whether a skilled artisan would know how to turn on lights on a frame to indicate information. Rather, the issue is would a skilled artisan have been able to close the gap between knowing an unseen slice position of a medical imaging device Appeal 2020-001453 Application 14/408,342 8 and then somehow converting that position to a pair of light to illuminate. Ans. 7. The Examiner further explains, “[t]he specification as filed and the skill in the art do not appear to disclose how a skilled artisan would go from the known slice position to a pair of lights that should be illuminated, which is where the lack of enablement arises.” Id. In reply, Appellant refers to Figures 5 and 8 and quotes portions of pages 5, 9, 10, 14, and 15 of the Specification to explain that different slices are identified by different color codes displayed by the visual indicators (light sources) on the frame. Reply Br. 5–6. We do not sustain the rejection of claims 6–10 and 12 because the Specification explains the correlation between different colors presented on the visual indicators and the position of the MR slices. For example, the Specification states: Based on the angles, the guidance module 64 further adjusts the light sources 80 to provide a visual indication as to position of the one or more slices of the real-time MR images displayed on the display device 74 positioned proximate to the subject 12. MR operators are used to identifying different slices by different color codes. Hence, it is advantageous to reuse this color coding to visualize the cross section of the slices. For each slice displayed, the corresponding light sources are set to the color coding the slice. Spec. 14:17–22. The Examiner does not question whether a person of ordinary skill in the art would be able to determine the position of an MR slice and “would know how to turn on lights on a frame to indicate information.” Ans. 7. Given the sophisticated nature of the field (magnetic resonance imaging for intrusive medical procedures), the Examiner does not identify any reason displaying information regarding a known position of an Appeal 2020-001453 Application 14/408,342 9 MR slice via colored lights would require undue experimentation. In other words, the Examiner agrees that such lights are usable for conveying information, and the Examiner does not adequately explain why conveyance of the particular information at issue in the rejection of claims 6–10 and 12 would be different in any way that would make a person of ordinary skill in the art unable to practice the invention. Rejection IV–Unpatentability over Sahni, (Sarvestani or Boernert), Schellenberg, and Anderson Claims 1, 3, 4, 11, 12, and 21–23 The Examiner finds that Sahni discloses many of the elements recited in claim 1, including a magnetic resonance (MR) system for guidance of a shaft or needle to a target of a subject and a frame configured to be positioned on a surface of a subject. Final Act. 7. However, the Examiner finds Sahni does not disclose visual indicators arranged on the frame around the opening as required by claim 1. Id. To remedy this deficiency, the Examiner finds that each of Boernert and Sarvestani discloses MR systems with “visual indicators arranged on the frame around the opening.” Id. at 7– 8 (citing Boernert, 11:11–12:38, 13:31–15:56, Figs. 1, 3; Sarvestani, ¶¶ 38, 48–50, Fig. 10). The dispositive issue in this rejection is whether the Examiner’s findings of fact regarding Boernert and Sarvestani are correct. Boernert Although the discussion of Boernert in the Final Office Action does not list a reference number for the component in Boernert the Examiner finds meets the “visual indicators” recitation of claim 1, Appellant infers that the Examiner relies on optical markers 15 for this requirement. See Appeal Br. 12–13. Appellant contends that optical markers 15 in Boernert fail to meet the requirement in claim 1 that a processor uses them to generate a Appeal 2020-001453 Application 14/408,342 10 visual indication of a deviation, from a planned trajectory, of a shaft or needle. See id. In response, the Examiner does not contest Appellant’s arguments regarding optical markers 15. Ans. 8. Instead, the Examiner states that display 45 in Boernert is “arranged around the Boernert device and displays visual indicators of tracking and location data generated by the system.” Id. In reply, Appellant contends that display 45 is merely a display mounted near an opening, but not plurality of indicators around the opening of the frame. Reply Br. 7. As a matter of claim construction, the broadest reasonable interpretation, in light of the Specification, of the phrase “a plurality of light sources spaced around the opening” is multiple sources of light, each placed at a different locations so as to surround an opening. In this regard, the Specification explains that the light sources “around” the opening may be arranged in a circle, a square, a rectangle, and an oval. See Spec. 10:23–25, Figs. 5–9. In light of the broadest reasonable interpretation of claim 1, we do not agree with the Examiner that display 45 of Boernert can accurately be characterized as visual indicators “arranged on the frame around the opening.” Final Act. 7. Rather, as shown in Figure 3A of Boernert, display 45 is a single, discrete device positioned in a location that is not around an opening in the sense required by claim 1. Sarvestani Appellant argues that Sarvestani merely discloses a single portable display 222, which, Appellant asserts, is not the same as a plurality of visual indicators spaced around an opening as recited in claim 1. Appeal Br. 13. Appeal 2020-001453 Application 14/408,342 11 In response, the Examiner states, “Appellant’s remarks should be found unpersuasive because discloses in Fig. 10 [sic] a display that can be placed around any of the frame openings disclosed in Sarvestani.” Ans. 8. Figure 10 of Sarvestani depicts display 222 as a discrete device that mounts to docking feature 822. See Sarvestani ¶ 48. Sarvestani suffers from a similar deficiency as the one discussed above regarding Boernert, namely, Sarvestani discloses a visual indicator (display 222), rectangular in shape, that is not positioned “around” an opening in accordance with the broadest reasonable interpretation of claim 1. See Sarvestani, Figs. 4, 10. As Appellant has the better position with respect to both Boernert and Sarvestani, and the Examiner’s findings for at least one of these references are required to support Rejection IV (see Final Act. 7–8), we do not sustain this rejection. Rejection V– Unpatentability over Sahni, Sarvestani, Schellenberg, and Anderson Claims 18 and 20 Claim 18 recites, in part, “one or more visual indicators arranged on the frame and encircling the opening.” Appeal Br. 21 (Claims App.). The Examiner finds display 222 of Sarvestani meets this claim limitation. See Final Act. 12; Ans. 9. We agree with Appellant that claim 18 requires the visual indictor(s) to encircle the opening in the recited frame and display 222 does not encircle such an opening. See Sarvestani, Figs. 4, 10. Accordingly, we do not sustain the rejection of claim 18, and claim 20 depending therefrom, as unpatentable over Sahni, Sarvestani, Schellenberg, and Anderson. Appeal 2020-001453 Application 14/408,342 12 CONCLUSION The Examiner’s rejections are reversed.
