Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Amendment / Arguments The examiner is not persuaded that the amendments overcome the prior art of record. Thus, the rejections under 103 are maintained. Lang teaches generating models during live patient sessions, or obtaining live patient data and supplying the data to the model (e.g. claims 34, 35, model viewed during range of motion test for patient, and other mapping in this office action). Lang also teaches tracking patient motion (i.e. a range of motion test) using a patient model, such as a skeletal model, as mapped in the prior and current office action. In response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). Applicant’s arguments are also respectfully somewhat conclusory and/or simply respectfully incorrect. And, with respect, Applicant also argues at times for features that the reference was not applied to teach. For example: Page 11 Remarks: Applicant admits that Wells teaches determining if a patient’s path of motion falls within a predetermined region, but somehow also argues that this does not teach current range of motion measurement values. This is incorrect. With respect, a determination that a patients’ path of motion is or is not in an intended location would necessarily require measuring the patient’s path of motion (i.e. how else can this assessment be made?) Page 11 Remarks: Applicant also argues that Wells does not teach AR HMD features. Wells was not applied to teach this. Pages 11-12 Remarks: Applicant arguing that Nash does not teach features Nash was not applied to teach (i.e. skeletal model features, or the determining step). Page 12 Remarks: Examiner respectfully agrees that Lang is a lengthy reference, which is why she respectfully provides a very detailed mapping of specific sections. Page 12 Remarks: Examiner does not cite to para. 867 of Lang, which Applicant is heavily focused on. Same with para. 1262. So these arguments do not address the rejection, rationale, or mapping in the prior office action, same with remaining paragraphs that Applicant discusses but was not used or referenced. The remainder of Applicant’s arguments are equally fragmented or do not address the mapping or combination as a whole. Yes, Lang is a long reference (Remarks, page 12), and the reference respectfully teaches what it is mapped. Accordingly, the rejections under 103 are maintained. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1, 3, 5, 6, 12, 14, 16, 17, 23 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Lang (U.S. Patent App. Pub. No. 2019/0380784 A1) in view of Wells (U.S. Patent App. Pub. No. 2018/0121728 A1; cited in IDS), and further in view of Nash (U.S. Patent App. Pub. No. 2018/0256258). Regarding claim 1: Lang teaches: a system for augmented reality patient assessment (see e.g., claim 31, system, in combination with para. 1529, augmented reality system related to patient care), the system comprising: an augmented reality (AR) head-mounted display (HMD) (claim 31, a see-through optical head mounted display); a depth sensor to generate depth sensor data for a patient (see paras. 250-251, which teach depth sensors that can be used to obtain live data of a patient) during a musculoskeletal assessment activity (see claims 34 or 35, which describe one example of a musculoskeletal assessment activity of a patient’s knee being moved into different positions, or moved through a range of motion); processing circuitry; and a memory that includes instructions, the instructions, when executed by the processing circuitry, cause the processing circuitry to (see claim 31, processor, in combination with para. 884, memory storing executable software): generate a skeletal model based on the depth sensor data during the musculoskeletal assessment activity (see Lang, e.g. para. 1168, which teaches using 3D image data to generate a patient model, in combination with para. 802, which teaches that Lang applies to musculoskeletal procedures, or even claims 34 or 35, as mapped above. In claim 34, the system is maintaining display of a patient’s virtual implant components in relationship to at least one anatomic structure, when the knee is moved into different positions of at least one of flexion, extension, rotation, abduction, adduction or combinations thereof. This teaches generation of a model during the activity (as knee is moved) (Alternative mapping to Nash reference: see Nash, para. 43, overlaying a skeletal model on a patient is known, via an AR device that has a depth camera (para. 21), such to obtain patient data to generate said model); Moreover, further with regard to Lang, the reference of Lang has other alternative mappings or additional teachings of generating skeletal models during a musculoskeletal activity (such as range of motion), which the examiner is providing for completeness: Para. 1329: patient virtual 3D models can be registered relative to live patient data, the “live patient data” can be data collected during a range of motion, as per Lang, claim 34 See para. 1332, reproduced in part below, which states that virtual data is typically displayed in conjunction with viewing or displaying live data of the patient. This paragraph is then followed by tables of non-limiting examples of virtual patient data. One of the tables (reproduced below), specifically lists range of motion data post-implant. A virtual model with a patient implant is a skeletal model. [AltContent: arrow] PNG media_image1.png 192 412 media_image1.png Greyscale [AltContent: arrow][AltContent: arrow] PNG media_image2.png 442 508 media_image2.png Greyscale track a patient motion during the musculoskeletal assessment activity using the skeletal model (Lang, claims 34-35, 55, patient motion is being tracked through a range of motion, or movement (examples: knee, hip or shoulder). See also above mapping to the generation of the skeletal model, which also applies here). Modifying Lang, in view of same, such to have included a skeletal model based on depth sensor data, per Lang, generated during a musculoskeletal assessment activity, such as Lang’s range of motion, and such that the model is viewed during a live patient assessment activity, such as a range of motion test, also all mapped in Lang, is all of taught and suggested by the prior art, and would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of Applicant’s See MPEP 2143(A). Re: the remaining features of claim 1, it would have been obvious for one of ordinary skill in the art to have combined and modified the applied reference(-s), in view of same, to have obtained: determine, from the skeletal model and the patient motion during the musculoskeletal assessment activity, a set of current range of motion measurement values for one or more musculoskeletal joints of the patient; and output the set of current range of motion measurement values for the one or more musculoskeletal joints overlaid on the patient for display on the AR HMD while the patient is being viewed through the AR HMD during the musculoskeletal assessment activity, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Re: determine step, Wells also teaches and illustrates range of motion assessments with patients. See e.g. Wells, Fig. 2, reproduced below for convenience. PNG media_image3.png 558 604 media_image3.png Greyscale In terms of determining a set of current range of motion measurement values, Wells teaches this in multiple locations, such as: Wells, para. 52: : “The video/animation evaluation component 404 includes an actual path the patient performed, with an actual starting location 408, an actual ending location 414, and an actual path of motion 412. T…In another example, if the actual path of motion 412 falls outside the intended edges 418 and 420, the patient's attempt at a clinical movement may be determined to be a failure. In another example, some amount of error may be tolerated, such as a brief movement outside the intended edges 418 and 420.” OR see Wells, para. 60: “The processor 502 may be used to receive information… such as a clinical movement captured using the movement capture apparatus 503. The processor 502 may analyze the clinical movement to determine a path of motion of the clinical movement, such as a path of motion on video captured by the movement capture apparatus 503. The processor 502 may automatically define a path region, such as by using the path of motion. The processor 502 may receive information about a movement of a patient along the path of motion, such as movement of the patient captured using the movement capture apparatus 503. The processor 502 may determine whether the movement was within the path region. In an example, the processor 502 may send feedback, such as to the feedback controller 508 or the display 510. The feedback may indicate whether the movement was within the path region. The display 510 may display the feedback, such as by visually indicating (e.g., on a user interface) whether the movement was within or outside the path region or where the movement may have been outside the path region. The feedback controller 508 may be used to send the feedback to the display 510, issue an audible alert, provide haptic feedback, or the like. In an example, the display 510 may be a screen, an augmented reality display, a virtual reality display, or the like.” OR, Wells, para. 61. At least these paragraphs from Wells teach determining a current range of motion measurement values based on patient motion (i.e. measurement values needed to determine the clinical path, a start and end position, and whether the patient’s movement as within the path region or clinical goals). Re: output step, see Wells, para. 60-61, which teach displaying or outputting information of whether the patient’s range of motion was within the path region, such as the path region that a user moved in his/her range of motion test, overlaid or superimposed. In terms of overlaying “measurement values”, Nash teaches that it is known to have an AR device and an AR display that can display virtual and real (e.g. patient) components, whereby the virtual components can include “measurements, angles” etc. for joints, as it relates to a skeleton. See para. 13 of Nash. Another teaching of measurement values for joints: joints such as the ones of Lang’s range of motion test. Finally, like Nash, Lang also teaches an AR HMD that can be worn and used while patient is being viewed (Lang, OHMD, paras. 4, 116, 255-56) Modifying Lang, such to superimpose or overlay a current range of motion measurement values, as per Nash and Wells, when Lang also teaches obtaining range of motion information of a patient (see mapping above), and when Lang also teaches the overlaying of virtual data on a patient’s live data as seen through HMD (Lang, para. 204), is all of taught and suggested by the prior art, and would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Further motivation is found in the prior art, to provide for a simultaneous visualization of live patient data with virtual data to facilitate patient care (Lang, para. 4). The prior art included each element recited in claim 1, although not necessarily in a single embodiment, with the only difference being between the claimed element and the prior art being the lack of actual combination of certain elements in a single prior art embodiment, as described above. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 3: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the system of claim 1, the instructions further causing the processing circuitry to: determine a target range of motion based on the musculoskeletal assessment activity (Lang, para. 867, target or desired range of motion is known) (Wells, targets are also known. See para. 20, 49 (target range of motion), 63 and claim 2); and output a graphical indication of the target range of motion for display on the AR HMD while the patient is being viewed through the AR HMD, (see Wells, para 49, Fig. 3). Modifying the applied references, such to include outputting a graphical element related to target range of motion, per Lang, with all references relevant to motion and ranges of motion of patients, for display on the HMD while the patient is viewed, per both references (Nash, para. 13) (Lang, para. 204)), would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). The prior art included each element recited in claim 3, although not necessarily in a single embodiment, with the only difference being between the claimed element and the prior art being the lack of actual combination of certain elements in a single prior art embodiment, as described and mapped above. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 5: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the system of claim 1, the instructions further causing the processing circuitry to receive motion sensor data from a motion sensor attached to a patient, the motion sensor data characterizing a musculoskeletal motion of the patient; wherein generating the skeletal model is further based on the motion sensor data, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Lang teaches that motion sensors to obtain human/patient movement data is known (paras. 136-37), such to obtain movement information from range of motion tests (claims 53-55, para. 867). This corresponds to motion sensor data characterizing a musculoskeletal motion of the patient. Lang also teaches that its patient models can be adjusted/modified, using intra-operative data (such as when the patient is performing range of motion tests, per Lang, and mapped in claim 1) (see para. 1168). Lang also teaches that its patient models can be further deformed/changed based on patient related features (para. 1144-1146). Modifying Lang, in view of same, such to include the above, and to generate a skeletal model (mapped in claim 1), based on range of motion data (also taught by Lang), when Lang also teaches/motivates this by describing range of motion, desired movement, and ligamentous laxity as three factors that a surgeon should consider while planning/performing surgery (para. 867), is taught, suggested and motivated by the prior art, and would have been obvious and predictable to one of ordinary skill. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 6: Lang teaches: the system of claim 1, the instructions further causing the processing circuitry to receive medical imaging data of a musculoskeletal joint of the patient; wherein generating the skeletal model is further based on the medical imaging data (para. 1168, patient models can be adjusted/modified, using intra-operative data. This can be imaging data. Id. See also para. 1271). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of Lang, to have obtained the above, motivated to be able to use and present the most recent and relevant patient information during medical procedures. Regarding claim 12: see also claim 1. The method of claim 12 corresponds to the functions performed by the system of claim 1; the same rationale for rejection applies. Regarding claim 14: see claim 3. These claims are similar; the same rationale for rejection applies. Regarding claim 16: see claim 5. These claims are similar; the same rationale for rejection applies. Regarding claim 17: see claim 6. These claims are similar; the same rationale for rejection applies. Regarding claim 23: see also claim 1. Lang teaches: a non-transitory machine-readable storage medium, comprising instructions that, (para. 884, memory storing executable software) responsive to being executed with processing circuitry of a computer-controlled device (para. 884, executed by processors, such as those of the system claim 31), cause the processing circuitry to: The instructions correspond to the functions performed by the system of claim 1; the same rationale for rejection applies. Regarding claim 25: see claim 3. These claims are similar; the same rationale for rejection applies. Claim(s) 2, 4, 13, 15 and 24 are rejected under 35 U.S.C. 103 as being unpatentable over Lang in view of Wells and Nash, and further in view of Dalvin (U.S. Patent App. Pub. No. 2019/0239850 A1). Regarding claim 2: It would have been obvious for one of ordinary skill in the art to have combined and modified the applied reference(-s), in view of same, to have obtained: the system of claim 1, the instructions further causing the processing circuitry to: receive a selection of the musculoskeletal assessment activity (Dalvin, para. 39 and/or Fig. 2); and output a description of the musculoskeletal assessment activity for display on the AR HMD while the patient is being viewed through the AR HMD (Dalvin, para 6), and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). As mapped above Dalvin teaches systems/methods for the “guidance of health-related examinations…via augmented and/or mixed reality…capable of displaying digital information to the user, examinee or other observer via augmented reality and/or mixed reality” (quoting para. 6). Guidance can be provided in the form of text instructions, or guiding graphics, which can be displayed on an AR display device, such as head-mounted display device (para. 6). Users can provide input and make selections (para. 39 and Fig. 2). Modifying the applied references, such to include the functionality of Dalvin, i.e. to guide a user/medical professional in the range of motion procedures as taught in Lang, is all of taught and suggested by the prior art, would have been obvious and predictable to one of ordinary skill, and that same person of ordinary skill would have been motivated to do so in order to “improve the quality of the data acquired during the examination, reduce inter-operator variability, or enable a clinician to do a medical examination that was previously difficult or impossible to perform with good results due to limitations in skill or capability” (motivation quoted directly from Dalvin, para. 6). One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 4: Dalvin teaches: the system of claim 1, the instructions further causing the processing circuitry to output a guided musculoskeletal activity for display on the AR HMD, the guided musculoskeletal activity providing a patient motion instruction for conducting the musculoskeletal assessment activity (para. 6, which teaches outputting guidance in the form of graphics or text instructions to assist users and medical practitioners with examinations). Modifying the applied references, such to include the functionality of Dalvin, i.e. to guide a user/medical professional in the range of motion procedures as taught in Lang, is all of taught and suggested by the prior art, would have been obvious and predictable to one of ordinary skill as of the effective filing date of Applicant’s claims, and that same person of ordinary skill would have been motivated to do so in order to “improve the quality of the data acquired during the examination, reduce inter-operator variability, or enable a clinician to do a medical examination that was previously difficult or impossible to perform with good results due to limitations in skill or capability” (motivation quoted directly from Dalvin, para. 6). See MPEP §2143(A). One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 13: see claim 2. These claims are similar; the same rationale for rejection applies. Regarding claim 15: see claim 4. These claims are similar; the same rationale for rejection applies. Regarding claim 24: see claim 2. These claims are similar; the same rationale for rejection applies. Claim(s) 7 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Lang in view of Wells and Nash, and further in view of Palo (U.S. Patent App. Pub. No. 2018/0289434 A1). Regarding claim 7: The applied references to claim 1 do not proactively teach claim 7. Consider the following. In analogous art, Palo teaches: the system of claim 1, the instructions further causing the processing circuitry to: receive a selection of a model surgical procedure (para. 35, select surgical templates; and/or para.41: from a drop-down menu of surgical procedures); generate a patient procedure model based on the model surgical procedure and the skeletal model (paras. 41-47, user can create a patient procedure model, and, para. 46, use images and files to do so. Modifying the applied references, such to use the skeletal model mapped in claim 1, as a file/image to use to create the procedure model of Palo, is all of taught and suggested by the prior art, would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A)); and output the patient procedure model for display on the AR HMD while the patient is being viewed through the AR HMD (see mapping to claim 1; Fig. 1 of Lang, output to OHMD). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to be able to use and present the most recent and relevant patient information during medical procedures. Regarding claim 18: see claim 7. These claims are similar; the same rationale for rejection applies. Claim(s) 8, 9, 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Lang in view of Wells and Nash, and further in view of Kurniawan (U.S. Patent App. Pub. No. 2020/0327986 A1). Regarding claim 8: It would have been obvious for one of ordinary skill in the art to have combined and modified the applied reference(-s), in view of same, to have obtained: the system of claim 1, the instructions further causing the processing circuitry to: generate a predicted postoperative skeletal model based on the skeletal model, the skeletal model including a preoperative skeletal model, the predicted postoperative skeletal model including an improved range of motion based on a surgical procedure; and output the predicted postoperative skeletal model overlaid on the patient for display on the AR HMD while the patient is being viewed through the AR HMD, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Lang teaches generating patient models (i.e. a skeletal model), as mapped in claim 1 (see Figs. 16A-B of Lang). This includes post-operative models (para. 1329, models can be based on post-op patient images), and models can be output for HMD display (mapping to claim 1, and Figs. 16A-B). In terms of a “predictive” postoperative model, Kurniawan teaches that it is known in the art of medical/patient care to include predictive analytics in a prediction system which collected health data from various sensors, and carries out predictive analysis through a virtual reality device (para. 5). For reference, six aspects of the system/methods of Kurniawan are listed in paras. 39-44, and the instant reference is not limited to any specific medical field (see paras. 54-56). Kurniawan also further teaches prediction in terms of 3D depth prediction, plane estimation, and 3D depth reconstruction (paras. 80, 139). Modifying the applied references, such to incorporate the teachings of Kurniawan, into a post-operative skeletal model (per Lang), that is based predictive analysis, per Kurniawan (i.e. predictive range of motion from a procedure of Lang, with pre-op/intra-op data on range of movement already collected, per Lang, and mapped above in claim 1), is all of taught, suggested and motivated by the prior art, and would have been obvious and predictable to one of ordinary skill. Motivations and problems that can be solved by including predictive analysis are also articulated in the Kurniawan reference (see paras. 2-3). One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 9: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the system of claim 8, the depth sensor further to generate postoperative depth sensor data for the patient during a postoperative musculoskeletal assessment activity; the instructions further causing the processing circuitry to: generate a revised postoperative skeletal model based on the postoperative depth sensor data; a output the revised postoperative skeletal model overlaid on the preoperative skeletal model for display on the AR HMD, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Lang teaches obtaining post-op images for model generation/revision (see mapping to claim 1 or claim 8), whereby images can be obtained via depth sensor (mapping to claim 1). Modifying the applied references, in view of Lang, such to revise a postop skeletal model based on postop images, all taught by Lang, would have been obvious and predictable to one of ordinary skill, with the additional motivation to use relevant patient data to revise/add information/edit patient models. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 19: see claim 8. These claims are similar; the same rationale for rejection applies. Regarding claim 20: see claim 9. These claims are similar; the same rationale for rejection applies. Claim(s) 10, 11, 21 and 22 are rejected under 35 U.S.C. 103 as being unpatentable over Lang in view of Wells and Nash, and further in view of Kurniawan and Palo. Regarding claim 10: Palo and Kurniawan teach: the system of claim 8, the instructions further causing the processing circuitry to receive a surgical procedure selection (Palo, para. 35, select surgical templates; and/or para.41: from a drop-down menu of surgical procedures), wherein the predicted postoperative skeletal model is further based on the surgical procedure selection (Kurniawan, see para. 5, the predictive system analyzes health data to provide recommendations. This includes patient information (para. 148)). Modifying the applied references, such that the relevant patient info/health data for which to perform predictive analysis, per Kurniawan, includes the patient’s surgical procedure (either performed or to be performed), selected in a menu based system of Palo, would have been obvious and predictable to one of ordinary skill, with the additional motivation to use relevant patient data to revise/add information/edit patient models. See also MPEP 2143(a). One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 11: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the system of claim 10, the instructions further causing the processing circuitry to: identify a list of surgical procedures associated with the musculoskeletal assessment activity; and output a selection prompt for the list of surgical procedures for display on the AR HMD, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Palo teaches that it is known to link different layers of information in a hierarchical fashion as it related to medical data, and teaches using the data to populate database fields for selection (e.g. claims 2-7). All of the analogous references are relevant to surgical procedures. Modifying the applied references, such to link a musculoskeletal activity (like range of motion/ movement, per Lang, and mapped in claim 1), to a surgical procedure (also per Lang, mapped in claim 1, and also taught by Palo), for selection prompt, per Palo, and display on a AR HMD (Lang, mapped throughout), is all of taught, suggested and motivated by the prior art, and would have been obvious and predictable to one of ordinary skill. Additional motivation would be to streamline linked data entry and display, per Palo. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Regarding claim 21: see claim 10. These claims are similar; the same rationale for rejection applies. Regarding claim 22: see claim 11. These claims are similar; the same rationale for rejection applies. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. * * * * * Any inquiry concerning this communication or earlier communications from the examiner should be directed to Sarah Lhymn whose telephone number is (571)270-0632.
