Patentability shall not be negatived by the manner in which the invention was made.
Claims 11-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over PERLER.
Re claims 11-15:
[Claim 11] PERLER discloses a method for providing a three-dimensional (3D) physical model for a surgical procedure (at least ¶ 5: a method may be used to correct a condition present in a patient; ¶ 44: a three-dimensional model of the patient's anatomy, or three-dimensional surface points that can be used to construct such a three-dimensional model), the method comprising: generating a computer model of osseous anatomy of a patient based on medical imaging data of the osseous anatomy (at least ¶ 8: obtaining a second bone model of the metatarsus, and virtually repositioning the second bone model relative to the first bone model to simulate reorientation of the metatarsus relative to the cuneiform to correct the bunion; ¶ 13: Using the first bone model to generate the cutting guide model may include converting the CT scan data to a CAD models, using the CAD model to obtain the first contour, and using the first contour to generate the first bone engagement surface of the cutting guide mode; ¶ 44: the method 100 may begin with a step 102 in which a CT scan (or another three-dimensional image) of the patient's anatomy is obtained. The step 102 may entail capturing a scan of only the particular bone(s) to be treated, or may entail capture of additional anatomic information, such as the surrounding tissues. Additionally or alternatively, the step 102 may entail receiving a previously captured image, for example, at a design and/or fabrication facility. Performance of the step 102 may result in possession of a three-dimensional model of the patient's anatomy, or three-dimensional surface points that can be used to construct such a three-dimensional model; ¶ 53: the method 120 may begin with a step 122 in which a CT scan (or another three-dimensional image) of the patient's foot is obtained. … ¶ 55: In a step 126, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct the bunion deformity. Such instrumentation may include a cutting guide that is attachable to the first cuneiform and the first metatarsus, with two guide features that facilitate resection of the cuneiform and the metatarsus in preparation for arthrodesis. In some embodiments, performance of the step 126 may include modelling the cutting guide with a bone apposition surface that is shaped to match contours of the surfaces of the cuneiform and the metatarsus, such that the bone apposition surface can lie directly on the corresponding contours of the first cuneiform and the first metatarsus; ¶ 101: The cut between the first bone segment 1040 and the second bone segment 1042 may be carried out virtually (for example, in CAD) on a model of the calcaneus 1000 obtained from a CT scan or other imaging of the patient's foot); generating a modified computer model of the osseous anatomy, the modified computer model altered from the computer model of the osseous anatomy such that the modified computer model represents the osseous anatomy after a surgical procedure (at least ¶¶ 44, 55: … the step 102 may entail receiving a previously captured image, for example, at a design and/or fabrication facility. Performance of the step 102 may result in possession of a three-dimensional model of the patient's anatomy, or three-dimensional surface points that can be used to construct such a three-dimensional mode; the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct the bunion deformity. Such instrumentation may include a cutting guide that is attachable to the first cuneiform and the first metatarsus, with two guide features that facilitate resection of the cuneiform and the metatarsus in preparation for arthrodesis. In some embodiments, performance of the step 126 may include modelling the cutting guide with a bone apposition surface that is shaped to match contours of the surfaces of the cuneiform and the metatarsus, such that the bone apposition surface can lie directly on the corresponding contours of the first cuneiform and the first metatarsus; ¶ 63: the degree of angular adjustment needed in each direction may be different for every patient. Use of a patient-specific cutting guide may help the surgeon obtain the optimal realignment in the lateral direction 260 and in the plantar direction 280 or the dorsal direction 290; ¶ 84: shaping may be accomplished by custom-designing the implant 610 for the patient, using the same models (for example, from CT scans) of the first metatarsus 230 and the first cuneiform 210 that were used to generate the cutting guide 300. Thus, the implant 610 may have a shape that provides secure attachment and/or fusion between the first metatarsus 230 and the first cuneiform 210 while avoiding proud edges or other protruding features that could otherwise interfere with surrounding tissues; ¶ 89: The bone apposition side 730 may be custom contoured to match the shapes of the first cuneiform 210 and/or the first metatarsus 230; ¶ 105: If desired, the model of the calcaneus 1000 may be divided and manipulated in CAD to simulate the repositioning of the heel 1050 pursuant to the medializing calcaneal osteotomy; ¶ 108: As in the case of the Evans calcaneal osteotomy, a custom cutting guide, or cutting guide 1053, may be generated to help the surgeon obtain the correction that was previously modeled and/or planned using the computer models of the foot 200); fabricating a preoperative 3D physical bone model of the osseous anatomy based on the computer model of the osseous anatomy before the surgical procedure (at least ¶ 48: where a range of cutting guides are available for a given procedure, analysis of the CAD data may facilitate pre-operative selection of the optimal cutting guide and/or optimal placement of the cutting guide on the bone. Similarly, if a range of implants may be used for a given procedure, analysis of the CAD data may facilitate pre-operative selection of the optimal implant(s); ¶¶ 51, 52, 53, 54, 55, 56, 57, 60-64, 69; ¶ 107: Patient-specific cutting guides may be designed, fabricated, and surgically used to facilitate any of these procedures through the presence of bone engagement surfaces that are shaped to rest on the particular bony surfaces adjacent to the osteotomy; ¶ 111: the bone plate 1070 may also be fabricated specifically for the foot 200, enabling the bone plate 1070 to maintain precisely the desired level of correction. When made specifically for the foot 200 in combination with each other, the implant 1060 and the bone plate 1070 may provide a highly predictable, precise, and customizable level of correction of the flat foot deformity); fabricating a postoperative 3D physical bone model of the osseous anatomy after the surgical procedure based on the modified computer model; and providing at least one of the preoperative 3D physical bone model and the postoperative 3D physical bone model to a user (at least ¶ 10: using the cutting guide model to fabricate a cutting guide having the first bone engagement surface, the second bone engagement surface, the first bone attachment feature, the second bone attachment feature, the first guide feature, and the second guide feature; ¶ 16: using at least the first bone model to generate an implant model defining a first bone-facing surface with a first shape that matches a first profile of a first resected surface of the first bone after resection of the first bone with a cutting guide fabricated using the cutting guide model; ¶ 18; ¶ 35: FIGS. 8A, 8B, and 8C are dorsal pre-operative, dorsal post-operative, and lateral post-operative views, respectively, of a foot …; ¶ 36: FIGS. 9A and 9B are dorsal post-operative and lateral post-operative views, respectively, of a foot treated …; ¶ 44: Performance of the step 102 may result in possession of a three-dimensional model of the patient's anatomy, or three-dimensional surface points that can be used to construct such a three-dimensional model; ¶ 98: FIGS. 8A, 8B, and 8C are dorsal pre-operative, dorsal post-operative, and lateral post-operative views, respectively, of a foot treated with an Evans calcaneal osteotomy; ¶ 99: FIGS. 9A and 9B are dorsal post-operative and lateral post-operative views, respectively, of a foot treated with a medializing calcaneal osteotomy, according to one embodiment. A medializing calcaneal osteotomy (heel slide) procedure is often used when the calcaneus (heel bone) has shifted out from underneath the leg; ¶ 100: FIG. 10 is a rear, perspective view of the foot 200 of FIG. 2, after performance of an Evans calcaneal osteotomy and a medializing calcaneal osteotomy with patient-specific instruments and/or implants; ¶ 101: The cut between the first bone segment 1040 and the second bone segment 1042 may be carried out virtually (for example, in CAD) on a model of the calcaneus 1000 obtained from a CT scan or other imaging of the patient's foot. Thus, the optimal realignment of the posterior end of the calcaneus 1000 can be obtained. If desired, a patient-specific cutting guide, or cutting guide 1043, may be generated in order to facilitate resection of the calcaneus 1000).
Alternatively, in the event PERLER is viewed as not disclosing all the claim features as claimed, for example, the “fabricating a postoperative 3D physical bone model of the osseous anatomy after the surgical procedure based on the modified computer model”, this manufacturing feature appears to amount to no more than repeating the customized manufacturing process of PERLER (at least ¶¶ 16, 84, 89, 108, 111) based on new patient information. Hence, it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the invention to have modified PERLER as claimed, because it is well settled that the mere duplication of a known step/part cannot be unobvious absent a showing to the contrary. See Dunbar v. Meyers, 94 U.S. 187, 195 (1876); Slawson v. Grand Street P.P. & F.R. Co., 107 U.S. 649 (1883); Topliff v. Topliff, 145 U.S. 156, 163 (1892); In re Scott, 25 App.D.C. 307 (CADC 1905); In re Volkmann, 28 App.D.C. 441 (CADC 1906); Condit Elec. Mfg. Co. v. Westinghouse Elec. & Mfg. Co., 200 F. 144 (1st Cir. 1912).
PERLER further teaches or at least suggests [(Claim 12)] wherein generating a modified computer model further comprises modifying the computer model based on a prescription provided by a surgeon (at least ¶ 3: Cutting guides are often used to help the surgeon properly locate the cut; ¶ 48: the model(s) may be used to select from available sizes of implants and/or instruments and advise the surgeon accordingly; ¶ 63: the degree of angular adjustment needed in each direction may be different for every patient. Use of a patient-specific cutting guide may help the surgeon obtain the optimal realignment in the lateral direction 260 and in the plantar direction 280 or the dorsal direction 290; ¶ 49: the result of the step 108 may be provision, to the surgeon, of one or more of the following: (1) one or more patient-specific instruments; (2) one or more patient-specific implants; (3) an instrument, selected from one or more available instrument sizes and/or configurations; (4) an implant, selected from one or more available implant sizes and/or configurations; (5) instructions for which instrument(s) to select from available instrument sizes and/or configurations; (6) instructions for which implant(s) to select from available implant sizes and/or configurations; (7) instructions for proper positioning or anchorage of one or more instruments to be used in the procedure; and (8) instructions for proper positioning or anchorage of one or more implants to be used in the procedure. These items may be provided to the surgeon directly, or to a medical device company or representative, for subsequent delivery to the surgeon; ¶ 50: In a step 110, the manufactured instrumentation may be used in surgery to facilitate treatment of the condition. In some embodiments, this may entail placing the modelled bone apposition surface against the corresponding contour of the bone used to obtain its shape, and then using the guide feature(s) to guide resection of one or more bones; ¶ 108: As in the case of the Evans calcaneal osteotomy, a custom cutting guide, or cutting guide 1053, may be generated to help the surgeon obtain the correction that was previously modeled and/or planned using the computer models of the foot 200), [(Claim 13)] wherein generating a modified computer model further comprises modifying the computer model in response to user input (at least ¶ 5: The surgical procedure may be selected from a first group consisting of a bunion correction osteotomy, an Evans calcaneal osteotomy, and a medializing calcaneal osteotomy. The first bone may be selected from a second group consisting a metatarsus, a cuneiform, and a calcaneus; ¶¶ 48, 49: the model(s) may be used to select from available sizes of implants and/or instruments and advise the surgeon accordingly … if a range of implants may be used for a given procedure, analysis of the CAD data may facilitate pre-operative selection of the optimal implant(s) … instructions for which implant(s) to select from available implant sizes and/or configurations; (7) instructions for proper positioning or anchorage of one or more instruments to be used in the procedure; and (8) instructions for proper positioning or anchorage of one or more implants to be used in the procedure), [(Claim 14)] the method of claim 11, comprising providing an indicator on one of the preoperative 3D physical bone model and the postoperative 3D physical bone model that distinguishes the preoperative 3D physical bone model from the postoperative 3D physical bone model, [(Claim 15)] wherein the modified computer model is configured to remediate a deformed bone condition of the osseous anatomy (at least ¶ 46: any known CAD program may be used to view and/or manipulate the CAD model and/or CT scan, and generate one or more instruments that are matched specifically to the size and/or shape of the patient's bone(s); ¶¶ 73, 74: FIGS. 3A through 3D, the body 310 may further have features that facilitate proper positioning of the cutting guide 300 on the first cuneiform 210 and the first metatarsus 230. More specifically, the body 310 may have a first bone indicator 360 with the text “CUN,” indicating that the end of the body 310 with the first bone indicator 360 is to be positioned over the first cuneiform 210. Similarly, the body 310 may have a second bone indicator 362 with the text “MET,” indicating that the end of the body 310 with the second bone indicator 362 is to be positioned over the first metatarsus 230. In addition, the body 310 may have a side indicator 370 with the text “LEFT,” indicating that the cutting guide 300 is to be used in connection with the patient's left foot. The side indicator 370 may be particularly helpful when bunion corrections are to be provided on both of the patient's feet. In such a case, the surgeon may manufacture or receive two separate cutting guides: one for the left foot (the foot 200 of FIG. 2) and another for the right foot (not shown) …).
In the event the above interpretation is viewed as not being reasonable, as noted earlier, this manufacturing feature appears to amount to no more than repeating the customized manufacturing process of PERLER (at least ¶¶ 16, 84, 89, 108, 111) based on new patient information. Hence, it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the invention to have modified PERLER as claimed, because it is well settled that the mere duplication of a known step/part cannot be unobvious absent a showing to the contrary. See Dunbar v. Meyers, 94 U.S. 187, 195 (1876); Slawson v. Grand Street P.P. & F.R. Co., 107 U.S. 649 (1883); Topliff v. Topliff, 145 U.S. 156, 163 (1892); In re Scott, 25 App.D.C. 307 (CADC 1905); In re Volkmann, 28 App.D.C. 441 (CADC 1906); Condit Elec. Mfg. Co. v. Westinghouse Elec. & Mfg. Co., 200 F. 144 (1st Cir. 1912).
Claim 16 is rejected under 35 U.S.C. 103 as obvious over PERLER.
Re claim 16:
[Claim 16] PERLER appears to be silent on the method of claim 11, comprising fabricating a second postoperative 3D physical bone model based on the computer model of the osseous anatomy. However, it would have been prima facie obvious to one of ordinary skill in the art, before the effective filing date of the invention, to have modified PERLER as claimed because it is well settled that the mere duplication of a known step/part cannot be unobvious absent a showing to the contrary. See Dunbar v. Meyers, 94 U.S. 187, 195 (1876); Slawson v. Grand Street P.P. & F.R. Co., 107 U.S. 649 (1883); Topliff v. Topliff, 145 U.S. 156, 163 (1892); In re Scott, 25 App.D.C. 307 (CADC 1905); In re Volkmann, 28 App.D.C. 441 (CADC 1906); Condit Elec. Mfg. Co. v. Westinghouse Elec. & Mfg. Co., 200 F. 144 (1st Cir. 1912).
