MORGAN, LARRY J. HUME, and LINZY T. McCARTNEY, Administrative Patent Judges. HUME, Administrative Patent Judge. DECISION ON APPEAL This is a decision on appeal under 35 U.S.C. § 134(a) of the Final Rejection of claims 1-27. An oral hearing was held March 18, 2014. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 The Real Party in Interest is Autodesk Inc. App. Br. 2. Appeal 2011-013557 Application 11/244,005 2 STATEMENT OF THE CASE2 The Invention Appellants’ invention relates to a workflow system for 3D model creation. Abstract. Exemplary Claims Claims 1 and 21, reproduced below, are representative of the subject matter on appeal (emphases added): 1. A process, comprising: allowing a user to paint within a 3D space using a computer creating a continuous definition of a hand drawn shape; and allowing the user to specify 3D model geometry in the 3D space associated with the hand drawn shape, the 3D model geometry directly specified by the user one of within and between the hand drawn shape and another hand drawn shape in the 3D space to thereby construct a 3D model. 21. A process, comprising: allowing a user to create a first planar drawing canvas within a 3D model space using a computer; and allowing the user to arbitrarily: create a second planar canvas within the 3D space; paint on the first canvas within the 3D space creating a continuous definition of a hand drawn shape; specify 3D model geometry on the first canvas in the 3D space associated with the paint; 2 Our decision refers to Appellants’ Appeal Brief (“App. Br.,” filed Apr. 13, 2011); Reply Brief (“Reply Br.,” filed Sep. 6, 2011); Examiner’s Answer (“Ans.,” mailed July 6, 2011); Final Office Action (“FOA,” mailed Aug. 4, 2010); and the original Specification (“Spec.,” filed Oct. 6, 2005). Appeal 2011-013557 Application 11/244,005 3 paint on the second canvas within the 3D space; specify directly 3D model geometry between the first and second canvases in the 3D space associated with the paint, the 3D model geometry one of within a canvas and directly connecting the canvases together in the 3D space to thereby construct the 3D model; and orient the one of the canvases. Prior Art The Examiner relies upon the following prior art in rejecting the claims on appeal: Aizawa US 4,858,150 Aug. 15, 1989 Roberts US 5,237,647 Aug. 17, 1993 Schell US 6,628,279 B1 Sep. 30, 2003 Golibrodski US 6,762,778 B1 Jul. 13, 2004 McDaniel US 2006/0082571 A1 Apr. 20, 2006 Rejections on Appeal3 1. Claims 1-6, 9-11, 13-15, 19, 20, and 22-27 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over the combination of Aizawa, McDaniel, and Schell. Ans. 4. 2. Claims 7, 8, 12, and 21 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over the combination of Aizawa, McDaniel, Schell, and Golibrodski. Ans. 17. 3 Although not before us on appeal, if further prosecution of this application should ensue, we leave it to the Examiner to determine whether the recitation added during prosecution to claim 1 of “directly specified by the user one of within and between the hand drawn shape and another hand drawn shape in the 3D space” and similar recitations in other independent claims meet the requirements of 35 U.S.C. § 112, second paragraph. Appeal 2011-013557 Application 11/244,005 4 3. Claims 16-18 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over the combination of Aizawa, McDaniel, Schell, and Roberts. Ans. 21. ISSUES AND ANALYSIS We only consider those arguments actually made by Appellants in reaching this decision, and we do not consider arguments that Appellants could have made but chose not to make in the Briefs so that any such arguments are deemed to be waived. 37 C.F.R. § 41.37(c)(1)(vii). We have reviewed the Examiner’s rejections in light of Appellants’ arguments that the Examiner has erred. We disagree with Appellants’ conclusions with respect to claims 1-27, and we adopt as our own (1) the findings and reasons set forth by the Examiner in the action from which this appeal is taken and (2) the reasons and rebuttals set forth by the Examiner in the Examiner’s Answer in response to Appellants’ arguments. However, we highlight and address specific findings and arguments regarding claims 1 and 21 for emphasis as follows. 1. § 103 Rejection of Claims 1-6, 9-11, 13-15, 19, 20, and 22-27 Issue 1 Appellants argue (App. Br. 13-19; Reply Br. 2-4) the Examiner’s rejection of claim 1 under 35 U.S.C. § 103(a) as being unpatentable over the combination of Aizawa, McDaniel, and Schell is in error. These contentions present us with the following issues: (a) Did the Examiner err in finding that the cited prior art combination teaches or suggests all the limitation of claim 1? Appeal 2011-013557 Application 11/244,005 5 (b) Did the Examiner err by not providing articulated reasoning with a rational underpinning in support of the Examiner’s legal conclusion of obviousness? Analysis Issue 1(a) Appellants first contend, “Aizawa entirely fails to discuss or teach [the limitation] ‘allowing the user to specify 3D model geometry in the 3D space,’” but instead, “merely discusses that a computer may take 2D wireframe data as input and infer three-dimensional geometry from this 2D data which is from a database.” App. Br. 14 (emphasis omitted). Appellants next contend Aizawa does not teach or suggest the limitation “allowing a user to paint within a 3D space using a computer,” because the reference only discusses retrieving 2D wire-frame data. Id. In response, the Examiner finds, and we agree, Appellants’ Specification does not distinguish the use of the term “paint” from the ordinary meaning one of ordinary skill in the art would understand the term to mean, particularly because, as Appellants admit, “[d]uring the paint operation . . . the user uses the typical drawing tools . . . available in a conventional drawing system.” Ans. 23-24 (quoting Spec. ¶ [0029]) (emphasis omitted). Although Aizawa uses 2D wireframes to construct a 3D model (Aizawa Abstract), we find Aizawa teaches or suggests a conventional paint system because [t]he inventive shape modeling system is designed to enter commands and parameters through input means including a graphic display unit 3, a tablet and stylus 4 and a keyboard 5 and operate on a computational unit 2 to produce data of 2- Appeal 2011-013557 Application 11/244,005 6 dimensional (will be termed simply “2-D” hereinafter) wire frame in a 2-D wire-frame generating process 9 and store the result in a data base 6. Aizawa col. 2, ll. 55-62. This portion of Aizawa, as identified by the Examiner (Ans. 24), teaches the use of conventional drawing tools including a tablet and stylus to “paint,” i.e., draw lines in two-dimensional space to be arranged and used to produce a three-dimensional shape. Thus, Aizawa does not merely “retrieve” 2D wireframe data, as alleged by Appellants. During prosecution, “the PTO gives claims their ‘broadest reasonable interpretation.’” In re Bigio, 381 F.3d 1320, 1324 (Fed. Cir. 2004) (quoting In re Hyatt, 211 F.3d 1367, 1372 (Fed. Cir. 2000)). We find Appellants have not provided a definition of “paint” in the Specification (¶ [0029]) that would preclude the Examiner’s broader interpretation.4 With respect to the disputed limitation, “allowing the user to specify 3D model geometry in the 3D space,” Appellants’ arguments are not persuasive because Aizawa teaches or suggests user arrangement of 2D 4 Any special meaning assigned to a term “must be sufficiently clear in the specification that any departure from common usage would be so understood by a person of experience in the field of the invention.” Multiform Desiccants, Inc. v. Medzam, Ltd., 133 F.3d 1473, 1477 (Fed. Cir. 1998); see also Helmsderfer v. Bobrick Washroom Equip., Inc., 527 F.3d 1379, 1381 (Fed. Cir. 2008) (“A patentee may act as its own lexicographer and assign to a term a unique definition that is different from its ordinary and customary meaning; however, a patentee must clearly express that intent in the written description.” (citations omitted)). See also Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005) (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments. In particular, we have expressly rejected the contention that if a patent describes only a single embodiment, the claims of the patent must be construed as being limited to that embodiment.” (citations omitted)). Appeal 2011-013557 Application 11/244,005 7 wireframes to produce a 3D shape, which we find teaches or suggests the limitation in dispute. Aizawa col. 3, l. 31 – col. 5, l. 7; see Ans. 24-25. Appellants also contend McDaniel “merely discusses inferring three- dimensional geometry from hand-drawn graphical input,” but “it is the three- dimensional conversion module 106 that interprets whether user input refers to 2-D and 3-D and 3D model geometry is not directly specified by the user.” App. Br. 15. In response, the Examiner emphasizes, and we agree, “McDaniel is relied upon to disclose the feature of the user painting [being] created through a continuous definition of a hand drawn shape and specifying the 3D model geometry is associated with the hand drawn shape” and further “discloses allowing a user to create three dimensional models from the two- dimensional drawings or sketches created by a user.” Ans. 25 (citing McDaniel ¶¶ [0003], [0084]). We find the disputed limitation reads on this teaching or suggestion of McDaniel. In addition, Aizawa also teaches or suggests the user specifying 3D model geometry by arranging planes of 2D wireframe drawings in the 3D space, which we find also teaches or suggests the disputed limitation. See Aizawa col. 4, ll. 46-53. Issue 1(b) With respect to Issue 1(b), i.e., the alleged improper motivational basis to combine the references in the manner suggested by the Examiner, we highlight the Examiner’s comprehensive summary of the basis for the unpatentability rejection of claim 1 over the combination of Aizawa, McDaniel, and Schell, the findings of which we adopt as our own: Appeal 2011-013557 Application 11/244,005 8 [T]he disclosures of Aizawa, McDaniel, and Schell are directed towards producing three-dimensional models. Aizawa, as discussed above, produces three-dimensional models using two- dimensional wire-frame images and three-dimensional plane elements. McDaniel, as discussed above, produces three dimensional models based on hand drawn images. Therefore, Aizawa’s direct specification of a three-dimensional model from wire-frame and plane elements would have realized the benefit of adding user produced three-dimensional elements to the final specification of the three-dimensional model. Schell (Abstract and figures 6A-6S) discloses using familiar pencil and paper techniques for producing a three-dimensional model. Aizawa already realizes a pencil and paper technique by allowing a user to draw two-dimensional wire-frame images, but not for final production of a three-dimensional model. Aizawa (Column 3, lines 52-65) relies on inputting commands for specifying coordinates for arranging the various elements to produce the final three-dimensional model; however, Schell (Column 12, lines 25-38) assembles a three-dimensional model without the need for complicated tools or concepts, but rather allows a user to draw elements in any order and assembling them. As a result, Schell discloses the 3D model geometry directly specified by the user one of within and between the hand drawn shape and another hand drawn shape in the 3D space to thereby construct a 3D model. Therefore, the combination of Schell with Aizawa and McDaniel would realize the benefit of assembling a final three dimensional model using familiar paper and pencil techniques of drawing the model together rather than inputting commands for specifying the coordinates in three-dimensional space for each element. Ans. 26-27. In the Reply, Appellants argue “a reason for the particular combinations has not been provided to establish obviousness [under KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398 (2007)],” “the rejection . . . is made by mere conclusory statements,” and “Applicants request that some Appeal 2011-013557 Application 11/244,005 9 reasoning with some rational underpinning be provided to support the legal conclusion of obviousness.” Reply Br. 4. We disagree with Appellants’ contentions in this regard, as we find the above-cited portion of the Answer provides the requested “reasoning with some rational underpinning . . . to support the legal conclusion of obviousness.” On this record, Appellants have provided no evidence that combining such teachings was “uniquely challenging or difficult for one of ordinary skill in the art,” Leapfrog Enterprises, Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007), nor have Appellants presented evidence that this incorporation yielded more than expected results. Rather, we find Appellants’ invention is simply a combination of known teachings that realize a predictable result. The Supreme Court has determined the conclusion of obviousness can be based on the interrelated teachings of multiple patents, the effects of demands known to the design community or present in the marketplace, and the background knowledge possessed by a person having ordinary skill in the art. KSR, 550 U.S. at 418. The skilled artisan would “be able to fit the teachings of multiple patents together like pieces of a puzzle” since the skilled artisan is “a person of ordinary creativity, not an automaton.” Id. at 420-21. Appellants allege the Examiner has attempted to “bring in the isolated teaching of McDaniel, Schell, Golibrodski and/or Roberts in the Aizawa system [which] amount[s] to improperly picking and choosing features from different references without regard to the teachings of the references as a whole.” Reply Br. 4 (emphases omitted). We disagree because the Examiner rejects the claims as obvious over the combined teachings of Appeal 2011-013557 Application 11/244,005 10 Aizawa, McDaniel, and Schell; the test for obviousness is not what the references show individually but what the combined teachings would have suggested to one of ordinary skill in the art. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Accordingly, Appellants have not provided sufficient evidence or argument to persuade us of any reversible error in the Examiner’s reading of the contested limitations on the cited prior art. Therefore, we sustain the Examiner’s legal conclusion of obviousness with respect to independent claim 1. In addition, Appellants raise what appear to be separate, substantive arguments (App. Br. 19-34) for patentability of dependent claims 2-6, 9-11, 13-15, 19, and 20, all rejected on the same basis as claim 1. To the extent these arguments are separate and substantive, we find the Examiner has rebutted each of those arguments in the Answer by a preponderance of the evidence. Ans. 6-9, 34-41. We adopt the Examiner’s findings as our own. Further, while Appellants raised what may appear to be separate, substantive arguments for patentability of independent claims 22-27, all rejected on the same basis as claim 1 (App. Br. 19-34), we find the issues presented generally turn on Issues 1(a) and 1(b) discussed above with respect to independent claim 1. To the extent Appellants may have presented additional substantive arguments for the patentability of these claims, we find the Examiner has rebutted each of those arguments in the Answer by a preponderance of the evidence. Ans. 9-17, 29-34. Again, we adopt the Examiner’s findings as our own. Appeal 2011-013557 Application 11/244,005 11 2. § 103(a) Rejection of Claims 16-18 As mentioned above, claims 16-18 stand rejected under § 103 as being unpatentable over the combination of Aizawa, McDaniel, and Schell in view of Roberts. We find Appellants have not provided separate, substantive arguments with respect to these claims, but instead generally allege the cited art, Roberts in particular, does not teach or suggest the recited features. We note the Examiner’s detailed response in the Answer. Ans. 21-22, 43-44. We also particularly note Appellants have not specifically rebutted the Examiner’s responsive arguments regarding claims 16-18 in their Reply Brief. Based upon our review of the record before us, we find Appellants have failed to present substantive arguments supported with specific factual evidence of sufficient character and weight to persuade us of error regarding the Examiner’s findings of facts and ultimate legal conclusion of obviousness. Further, mere attorney arguments and conclusory statements unsupported by factual evidence are entitled to little probative value. In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997); see also In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984); Ex parte Belinne, No. 2009-004693, slip op. at 7-8 (BPAI Aug. 10, 2009) (informative), available at http://www.uspto.gov/web/offices/dcom/bpai/its/fd09004693.pdf. See In re Lovin, 652 F.3d 1349, 1357 (Fed. Cir. 2011) (“[W]e hold that the Board reasonably interpreted Rule 41.37 to require more substantive arguments in an appeal brief than a mere recitation of the claim elements and a naked assertion that the corresponding elements were not found in the prior art.”); cf. In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) (“It is Appeal 2011-013557 Application 11/244,005 12 not the function of this court to examine the claims in greater detail than argued by an appellant, looking for [patentable] distinctions over the prior art.”). Arguments not made are therefore waived. See 37 C.F.R. § 41.37(c)(1)(vii). We therefore sustain the rejection of claims 16-18. 3. § 103 Rejection of Claims 7, 8, 12, and 21 Issue 2 Appellants argue (App. Br. 38-41) the Examiner’s rejection of claims 7, 8, 12, and 21 under 35 U.S.C. § 103(a) as being unpatentable over the combination of Aizawa, McDaniel, Schell, and Golibrodski is in error. These contentions present us with the following issue: Did the Examiner err in finding that the cited prior art combination teaches or suggests the limitation of “allowing the user to arbitrarily . . . specify directly 3D model geometry between the first and second canvases in the 3D space associated with the paint, the 3D model geometry one of within a canvas and directly connecting the canvases together in the 3D space to thereby construct the 3D model,” as recited in claim 21? Analysis In disagreement with the Examiner’s findings (FOA 14-15), Appellants contend Aizawa does not teach or suggest allowing the user to arbitrarily “specify 3D model geometry on the first canvas in the 3D space associated with the paint.” App. Br. 38 (citing Aizawa Fig. 2; col. 4, ll. 57-65). We note the issues raised with respect to independent claim 21 are substantially the same as those raised in connection with independent Appeal 2011-013557 Application 11/244,005 13 claim 1, discussed supra, with the addition of the terms “canvas” and “canvases.” For example, Appellants contend Aizawa fails to discuss “specify 3D model geometry on the first canvas in the 3D space associated with the paint.” . . . [and] Figure 2 of Aizawa merely shows that 2-D wire-frame data is retrieved and that 3-D planes and [sic] made and a 3-D transformation takes place based on this 2-D wire-frame data. Id. Thus, Appellants again argue Aizawa’s teaching and suggestion of assembling 2D wireframes into 3D objects is irrelevant to the claimed invention, which involves “painting.” We disagree for the reasons cited above with respect to the rejection of claim 1. We further note Appellants’ arguments in the Reply Brief (Reply Br. 4) in response to the Examiner’s findings do not specifically rebut the Examiner’s findings (Ans. 19-21, 41- 42), but instead continue to allege improper motivation to combine the references in the manner suggested by the Examiner, a contention we have dealt with above in connection with Issue 1(b). Accordingly, Appellants have not provided sufficient evidence or argument to persuade us of any reversible error in the Examiner’s reading of the contested limitations on the cited prior art. Therefore, we sustain the Examiner’s legal conclusion of obviousness with respect to independent claim 21. In addition, Appellants raise what appear to be separate, substantive arguments (App. Br. 41, 42) for patentability of dependent claims 7, 8, and 12, all rejected on the same basis as claim 21. To the extent these arguments are separate and substantive, we find the Examiner has rebutted each of those arguments in the Answer by a preponderance of the evidence. Ans. 18-19, 42-43. We adopt the Examiner’s findings as our own. Appeal 2011-013557 Application 11/244,005 14 CONCLUSION The Examiner did not err with respect to any of the unpatentability rejections of claims 1-27 under 35 U.S.C. § 103(a) over the various combinations of the prior art of record, and we sustain the rejections. DECISION We affirm the Examiner’s decision rejecting claims 1-27. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv) (2011). AFFIRMED bab Copy with citationCopy as parenthetical citation
