JENKS, RICHARD J. SMITH, and RACHEL H. TOWNSEND, Administrative Patent Judges. SMITH, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35U.S.C. § 134 involving claims to a method for providing nuclear medicine (NM) persistence images. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 According to Appellant, the real party in interest is General Electric Company. (Br. 3.) Appeal 2016-003008 Application 12/640,761 STATEMENT OF THE CASE Claims on Appeal Claims 1—27 are on appeal. (Claims Appendix, Br. 27—31.) Claim 1 is illustrative and reads as follows: 1. A method for providing nuclear medicine (NM) persistence images, the method comprising: acquiring a persistence nuclear emission image of a patient injected with a radiopharmaceutical in a persistence data acquisition mode; determining an assigned display color corresponding to NM persistence image information including detected nuclear activity from the radiopharmaceutical for each of a plurality of event count values; color mapping the acquired NM persistence image information using the assigned display colors; generating with a processor a color NM persistence image based on the color mapping; displaying the generated color NM persistence image before an NM study acquisition mode of operation wherein nuclear activity or event count information is acquired and stored for a diagnostic NM study; and performing the NM study acquisition using positioning based on a manual input provided responsive to displaying the generated color NM persistence image. Examiner’s Rejections 1. Claims 1—27 stand rejected under 35 U.S.C. § 112(b) or 35 U.S.C. §112 (pre-AIA), second paragraph, as indefinite. (Final Act. 2—3.)2 2. Claims 1—4, 7, 8, 10-15, 17, 19, and 21—27 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Shai,3 Strauss,4 LeBlanc,5 and in 2 Office Action dated Feb. 4, 2015. 3 Shai et al., US 2007/0232881 Al, pub.

Jan. 2, 2003 (“Strauss”). 5 LeBlanc et al., US 5,989,189, issued Nov. 23, 1999 (“LeBlanc”). 2 Appeal 2016-003008 Application 12/640,761 view of the skill in the art at the time of the invention. (Final Act. 3—10.) 3. Claims 5, 6, 9, 16, 18, and 20 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Shai, Strauss, LeBlanc, and in view of the skill in the art at the time of the invention, and Anglin.6 (Final Act. 10.) FINDINGS OF FACT We adopt the Examiner’s findings with regard to the scope and content of, and reason to combine, the prior art. The following findings are included for emphasis and reference purposes. FF 1. The Specification states that: NM imaging systems . . . use one or more image detectors to acquire imaging data, such as gamma ray or photon imaging data. The image detectors may be gamma cameras that acquire two- dimensional views of three-dimensional distributions of emitted radionuclides (from an injected radioisotope) from a patient being imaged. (Spec. 12.) FF 2. The Specification states that: In some NM imaging studies, the [region of interest] is positioned during a persistence imaging phase. During this persistence phase of imaging, the gray level noisy images, for example, in cardiac SPECT imaging, makes the identification of the heart organ very difficult, thereby resulting in difficulty positioning the patient such that the heart is in the middle of the view and within the [field-of-view] of the gamma camera. (Id. at 13.) FF 3. Shai teaches that: When imaging a specific structure, organ or anatomy of a patient, such as the heart, liver or kidney, the patient must be positioned in relation to the detector or camera of the imaging system such that the structure to be imaged is within the field of view (FOV) 6 Anglin, JR. et al., US 2007/0255115 Al, pub. Nov. 1, 2007 (“Anglin”). 3 Appeal 2016-003008 Application 12/640,761 of one or more imaging detectors. Certain scanning methods, such as nuclear tomography cardiology scanning, wherein the detector(s) rotate around the patient, require patient positioning so that the heart is as close as possible to the center of the Detector’s FOV. Within NM, the patient is typically positioned by an operator who manually adjusts the patient table and the imaging detector(s) while viewing the persistence image until the operator determines that the patient’s heart or other structure of interest is centered within the FOV of the detector(s). (Shai 113—4.) FF 4. Strauss teaches that “[gjamma ray imaging devices function by accumulating signal arising from gamma rays emitted from the subject over time.” (Strauss 1155.) FF 5. Strauss teaches that: In most suitable cameras, the measurement of gamma ray emission generates a voltage signal which can either be displayed on a CRT or stored and/or analyzed by a computer as an array of numbers. These numbers are used to generate an image by standard imaging methods. For example, the image is typically analyzed by normalizing the gamma ray counts (either to a fixed, pre-selected value, or to the maximum number detected in any pixel) and converting the normalized number to a brightness (greyscale) or to a color (pseudocolor) that is displayed on a monitor. {Id. at 1164.) FF 6. The Examiner finds that: Shai discloses a device method for providing nuclear medicine (NM) persistence images, the method comprising: acquiring a nuclear emission image of a patient in a persistence data acquisition mode using an image detector []; generating with a processor a NM persistence image []; and displaying the generated NM persistence image before an NM acquisition 4 Appeal 2016-003008 Application 12/640,761 study mode wherein nuclear activity or event count information is acquired and stored for a diagnostic study and performing the NM study acquisition using positioning based on a manual input provided responsive to displaying the generated NM persistence image . . . Shai does not specifically indicate if the image is a color image or not. (Final Act. 3—4, citing Shai Tflf 1 4.) FF 7. The Examiner finds that Straus[s] discloses a similar NM imaging technique, comprising injecting a patient with a radiopharmaceutical; determining an assigned display color corresponding to NM persistence image information including detected nuclear activity from the radiopharmaceutical for each of a plurality of event count values; color mapping the acquired NM persistence image information using the assigned display colors; and creating a color map (Final Act. 4, citing Strauss 150—159 and 163—166.) FF 8. The Examiner finds that “LeBlanc discloses a similar medical imaging display system, wherein various colors are used to provide intuitive representations of biological areas possessing varying properties so that a user can easily discern different regions of interest.” (Final Act. 4, citing LeBlanc Abstract and col. 2,11. 19-58, col. 6,11. 57—67, col. 7,11. 1—33, and col. 8,11. 41-62.) FF 9. The Examiner “takes Official Notice that NM acquisition study modes wherein nuclear activity or event count information is acquired and stored for a diagnostic study are well known in the art and that storing data for later study is beneficial for creating a record of an imaging study.” (Final Act. 5.) 5 Appeal 2016-003008 Application 12/640,761 DISCUSSION Rejection No. 1 Issue Whether a preponderance of evidence of record supports the Examiner’s indefiniteness rejection under 35 U.S.C. § 112(b) or 35 U.S.C. §112 (pre-AIA), second paragraph. Analysis The Examiner finds that independent claims 1,15, and 19 are indefinite “because it is unclear what is meant by a manual input and how the input is responsive to displaying a persistence image.” (Final Act. 2.) The Examiner further finds that claims 21 and 22 are indefinite “because it is unclear what count levels are associated with a diagnostically relevant image,” and “what is considered a diagnostically relevant image,” and “how the diagnostically relevant images are different than the ones acquired.”7 {Id. at 2—3.) Appellant refers to the Specification and argues that “terms such as ‘manual input’ and ‘responsive’ are well understood under their plain meaning.” (Br. 8—9.) Moreover, Appellant argues that “‘diagnostic’ and ‘relevant’ are commonly used and well understood terms.” {Id. at 9.) Appellant further argues that “under the plain language, and consistent with the specification, a diagnostically relevant image is an image that may be used for diagnostic purposes. In contrast, persistence images do not contain enough information for diagnostic use.” {Id. at 10.) 7 Claim 1, for example, refers to “event count” and “a diagnostic NM study.” (Br. 27.) 6 Appeal 2016-003008 Application 12/640,761 We find that Appellant has the better position. “A claim is indefinite when it contains words or phrases whose meaning is unclear.” MPEP § 2173.05(e); see In re Packard, 751 F.3d 1307, 1310-14 (Fed. Cir. 2014). In considering an indefmiteness rejection, the issue is whether one of ordinary skill in the art would understand what is claimed when the claim is read in light of the Specification. See Packard, 751 F.3d at 1312—13. Here, we find that the terms at issue are well known and understood by those of skill in the art. (See FF 1—9.) Moreover, we note the Examiner’s statement regarding updating “a common place procedure using black and white images with color images,” and agree with the Examiner that the skill in the art of nuclear medicine imaging is exceptionally high, and it is a simple matter to create a color image in substitution of a black and white image. Moreover, the background section of Shai discloses the exact persistence imaging procedure of manually positioning a patient as claimed but for color images. (Ans. 9.) Accordingly, the rejection for indefmiteness is reversed. Conclusion A preponderance of evidence of record fails to support the Examiner’s rejection for indefmiteness under 35 U.S.C. § 112. Rejection No. 2 We adopt as our own the Examiner’s findings, analysis, and conclusions regarding the obviousness rejections, as set forth in the Final Action (Final Act. 3—14) and Answer (Ans. 4—10). We discern no error in the rejections of the claims as obvious. 7 Appeal 2016-003008 Application 12/640,761 Issue Whether a preponderance of evidence of record supports the Examiner’s rejection under 35 U.S.C. § 103(a). Analysis Claim 1 Appellant argues that “the cited references do not teach generation and display of a color persistence image” and “fail to teach performing an NM study acquisition using positioning based on a manual input that has been provided responsive to displaying the generated color NM persistence image.” (Br. 14—15.) We are not persuaded. The rejection is based on the combination of the cited art, and the Examiner concludes that [i]t would have been obvious to one of skill in the art to have combined the method of Shai with the further teachings of Straus[s] because doing so would create a color image that is easier to use and in which it is easier to differentiate regions of interest. Further, a color image is more appealing to the eye than a black and white image. Examiner also notes that color and black and white images are well known substitutes in the field of medical imaging. (Final Act. 4.) See In re Keller, 642 F.2d 413, 425 (CCPA 1981) (citing cases) (the test for obviousness is “what the combined teachings of the references would have suggested to those of ordinary skill in the art”). Moreover, as the Supreme Court explained in KSR, “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR Int 7 v. Teleflex Inc., 550 U.S. 398, 416 (2007); see also id. at 417 (“[Wjhen a patent ‘simply arranges old elements with each 8 Appeal 2016-003008 Application 12/640,761 performing the same function it had been known to perform’ and yields no more than one would expect from such an arrangement, the combination is obvious.”) (quoting Sakraida v. Ag Pro, Inc., 425 U.S. 273, 282 (1976)). Here, Appellant merely substitutes a color image in place of a black and white image, yielding a predictable result. Appellant also argues that the Examiner “does not provide a sufficient rationale for combining the references,” referring to the Examiner’s statement that [i]t would have been obvious to one of skill in the art to have performed the procedure disclosed in para 1-4 of [Shai] with the further teachings of the skill in the art because doing so would allow the procedure disclosed in [Shai] para 1-4 to generate an image usable in later studies and create a record of the [generated] image. (Br. 15—16, citing Final Act. 5; see FF 6.) Appellant contests this “rationale” by stating that “persistence images are not used in later studies, but instead only for positioning a patient.” (Br. 16.) We are not persuaded because Appellant misconstrues the Examiner’s statement. Other than using color images, Shai discloses the same persistence imaging procedure as claimed, which patient positioning procedure allows the generation of an image “usable in later studies” (i.e. an image subsequent to the persistence image) and the creation of a record of the subsequently generated image.8 This is clear from the Official Notice (FF 9) that immediately precedes the statement contested by Appellant. (See Final Act. 5.) 8 See the last phrase of claim 1: “performing the NM study acquisition using positioning . . . .” (Br. 27.) 9 Appeal 2016-003008 Application 12/640,761 Appellant contests the Examiner’s reliance on the Shai reference because Shai “stresses automatic adjustment or automatic positioning” and “mentions, in passing, previously employed user adjusted approaches.” (Br. 16.) Accordingly, Appellant argues that (1) modifying Shai “would change a principle of operation of Shai and/or render Shai unfit for an intended purpose,” and (2) Shai teaches away from the claimed invention. {Id. at 16— 18.) We are not persuaded. As an initial matter, the Examiner does not rely on Shai for its teachings regarding automatic adjustment or positioning, but for its teaching of the well known, prior art practice of persistence imaging using manual input. (FF 3.) Moreover, Appellant’s claims require “manual input” (not automatic adjustment or positioning), and nothing in the prior art teaches that the use of color images rather than black and white for persistence imaging would have resulted in an inoperable process. See In re Urbanski, 809 F.3d 1237, 1243—44 (Fed. Cir. 2016); see also In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (affirming the Board’s determination that “the difference in the circuitry—electrical versus optical—does not affect the overall principle of operation of a programmable arithmetic processor”). Furthermore, the fact that Shai may teach a preference for automatic positioning, or an improvement over the prior art manual positioning technique, does not constitute a teaching away. See In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Accordingly, for the reasons of record and as set forth above, we affirm the rejection of claim 1. Dependent claims Appellant advances arguments regarding dependent claims 11, 14, 21, 10 Appeal 2016-003008 Application 12/640,761 22, 26, and 27. (Br. 18—23.) We have considered those arguments in light of the Examiner’s rejections and responses, and specifically adopt as our own the Examiner’s findings, analysis, and conclusions regarding those dependent claims. We note, for emphasis, that Appellant contests certain findings that the Examiner identifies as “well known,” or that the Examiner takes Official Notice of (see FF 9), but Appellant fails to explain why the finding or notice is incorrect.9 (See, e.g., Br. 19 regarding claim 11 and Br. 21—22 regarding claims 21—22.) We are similarly unpersuaded by Appellant’s hindsight argument because it also fails to explain why the Examiner’s finding that “[i]t was well within the skill in the art to optimize the amount of data collected” (Final Act. 14) was incorrect (i.e. why it was not within the skill in the art). (Br. 21—22.) Accordingly, for the reasons of record and as set forth above, we affirm the rejections of claims 11, 14, 21, 22, 26, and 27. Independent claims 15 and 19 For claims 15 and 19, Appellant restates the wording of the claims, and contests the rejections by relying on the arguments advanced in connection with claim 1. (Br. 23—25.) Accordingly, for the reasons of record and as set forth above in connection with claim 1, we affirm the rejections of claims 15 and 19. See 37 C.F.R. § 41.37(c)(l)(iv); see also In reLovin, 652 F.3d 1349, 1357 (Fed. Cir. 2011). 9 As stated in MPEP § 2144.03(C), “[t]o adequately traverse such a finding [of official notice or common knowledge], an applicant must specifically point out the supposed errors in the examiner’s action, which would include stating why the noticed fact is not considered to be common knowledge or well-known in the art.” 11 Appeal 2016-003008 Application 12/640,761 Rejection No. 3 Appellant contests the rejection by relying on the dependency of claims 5, 6, 9, 16, 18, and 20 from claims 1, 15, or 19. (Br. 25.) Accordingly, for the reasons of record and as set forth above, we affirm the rejection of claims 5, 6, 9, 16, 18, and 20. Conclusions of Law Rejection No. 2: A preponderance of evidence of record supports the Examiner’s rejection of independent claims 1,15, and 19, and dependent claims 11, 14, 21, 22, 26, and 27 under 35 U.S.C. § 103(a). Claims 2-4, 7, 8, 10, 12—14, and 23—25 fall with claim 1, and claim 17 falls with claim 15. Rejection No. 3: A preponderance of evidence of record supports the Examiner’s rejection of claims 5, 6, 9, 16, 18, and 20 under 35 U.S.C. § 103(a). SUMMARY We reverse the rejection for indefiniteness. We affirm the rejections for obviousness. TIME PERIOD FOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
