STRAUSS, AMBER L. HAGY, and MICHAEL M. BARRY, Administrative Patent Judges. STRAUSS, Administrative Patent Judge. DECISION ON APPEAL Appeal2015-000005 Application 12/501,416 STATE~vfENT OF THE CASE Appellant appeals under 35 U.S.C. § 134(a) from a rejection of claims 1-5, 11-16, 18-21, and 23. Claims 6-10, 17, and 22 are indicated to be allowable. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm-in-part. THE INVENTION The claims are directed to modifying a projected image to correct for irregularities present in a rendering medium, i.e., a surface onto which the image is projected. Spec. i-f 1. Claims 1 and 2, reproduced below, are representative of the claimed subject matter: 1. A method, comprising operating a physical processor to perform operations comprising: deriving a first derived matrix of transport coefficients and a second derived matrix of transport coefficients from a primary matrix of transport coefficients, wherein each of the transport coefficients describes transport of a respective image forming element from a first position onto one or more image forming elements at a second position; ascertaining an approximate inverse of the first derived matrix; determining a modified version of a projection image from the projection image, the approximated inverse of the first derived matrix, and the second derived matrix; and rendering the modified version of the projection image from the first position onto a physical medium at the second position. 2. The method of claim 1, wherein the deriving comprises decomposing the primary matrix (T) into the first derived matrix (DI) and the second derived matrix (D2) such that T=Dl +D2. 2 Appeal2015-000005 Application 12/501,416 REFERENCES The prior art relied upon by the Examiner in rejecting the claims on appeal is: Bui Tan et al. us 5,528,528 US 2009/0073324 Al REJECTIONS June 18, 1996 Mar. 19, 2009 The Examiner rejected claims 1-5, 11-16, 18-21, and 23 under 35 U.S.C. §103(a) as being unpatentable over Tan and Bui. Final Act. 3-16. APPELLANT'S CONTENTIONS 1. In connection with the rejection of claim 1, the sparse matrix factorization techniques disclosed by Bui are incompatible with and would not be applied to manipulating Tan's light transport matrices, thereby rendering the modification of Tan according to Bui improper. App. Br. 5-7. 2. In connection with the rejection of claim 2, the sparse factorization techniques disclosed by Bui involve decomposing a matrix T into a product of first and second derived matrices, not the sum required by claim 2. App. Br. 8. ANALYSIS We have reviewed the Examiner's rejection in light of Appellant's arguments that the Examiner has erred. In connection with the rejection of claim 2, we agree with Appellant's conclusion. However, in connection with claim 1, we disagree with Appellant's conclusions and we adopt as our own (1) the findings and reasons set forth by the Examiner in the action from 3 Appeal2015-000005 Application 12/501,416 which this appeal is taken and (2) the reasons set forth by the Examiner in the Examiner's Answer in response to Appellant's Appeal Brief and concur with the conclusions reached by the Examiner. We highlight the following for emphasis. In connection with claim 1, Appellant contends "one skilled in the art would [not] have had any apparent reason to 'combine' the teachings of Tan and Bui in a manner that would result in the subject matter defined in the 'deriving' element of claim 1." App. Br. 7. Appellant argues Tan discloses transport matrices Tl and T2 that are light transport coefficient matrices, i.e., matrices that are fully populated with non-zero light transport coefficient values. Id. In contrast, according to Appellant, Bui discloses sparse matrix factorization techniques that are applicable not to Tan's light transport coefficient matrices but only to sparse matrices, i.e., matrices that are populated primarily with zeros. Id. Thus, according to Appellant, the combination of Tan and Bui is improper because "[t]he Examiner ... has not shown that Tan discloses any DCT coefficient matrices to which the sparse matrix factorization techniques disclosed in Bui could be applied." Id. In response to Appellant's arguments that the techniques of Bui are incompatible with the light transport coefficient matrices of Tan, the Examiner finds Appellant has provided insufficient explanation or evidence in support of the argued assertions. Ans. 16-17. Furthermore, the Examiner finds the independent claims do not specify the exact characteristics of the required matrices, including whether the claims pertain to matrices having only non-zero values or otherwise. Ans. 17. Instead, the Examiner maintains one skilled in the art would "combine the elements of Tan [] and 4 Appeal2015-000005 Application 12/501,416 Bui in order to provide more efficient use of hardware application[ s] ... , particularly if certain transforms occur infrequently." Final Act. 6. Appellant's contention is unpersuasive of reversible Examiner error. As noted by the Examiner (Ans. 16-17), other than a conclusory statement and attorney argument, 1 Appellant provides insufficient evidence the techniques of Bui are so incompatible with the matrices of Tan that one skilled in the art would not combine their respective teachings. In particular, the Examiner relies on Bui only for disclosing deriving matrices Tl and T2 from a single primary matrix rather than the separate p 1 and p2 matrices of Tan. Final Act. 5---6. Not only are the specific features argued to be incompatible absent from the disputed claims, but Appellant's argument improperly relies on wholesale incorporation/combination of methodologies rather than what the combination of Bui and Tan teaches and suggests. The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. In re Keller, 642 F.2d 413, 425 (CCPA 1981). The artisan is not compelled to blindly follow the teaching of one prior art reference over the other without the exercise of independent judgment. See Lear Siegler, Inc. v. Aeroquip Corp., 733 F.2d 881, 889 (Fed. Cir. 1984). We are further mindful that the skilled artisan would "be able to fit the teachings of multiple patents 1 Attorney arguments and conclusory statements that are unsupported by factual evidence are entitled to little probative value. See 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). 5 Appeal2015-000005 Application 12/501,416 together like pieces of a puzzle" because the skilled artisan is "a person of ordinary creativity, not an automaton." KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398, 420, 421 (2007). Here, Appellant has not demonstrated the Examiner's proffered combination in support of the conclusion of obviousness would have been "uniquely challenging or difficult for one of ordinary skill in the art." Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (citing KSR, 550 U.S. at 418). For the reasons emphasized supra, we are unpersuaded of error in the rejection of independent claim 1. Accordingly, we sustain the rejection of independent claim 1 and, for the same reasons, the rejection of independent claims 13 and 18 under 35 U.S.C. §103(a) over Tan and Bui, together with the rejection of dependent claims 11, 12, and 23, which are not separately argued. In connection with the rejection of claim 2, the Examiner concludes use of the phrase "such that" preceding recitation of the equation "T=Dl +D2" results in the equation being interpreted as an intended use of the deriving and/or decomposing steps and, therefore, not limiting. Ans. 17. The Examiner further finds "multiplication is merely addition that is done repeatedly a certain number of times, which can still cover the matrix decomposition as disclosed in the claims," i.e., such that T=Dl +D2. Ans. 18. Appellant argues Bui's sparse matrix factorization involves decomposing a matrix into a product of two matrices, not into a sum of first and second derived matrices as claimed. App. Br. 8. We find Appellant's contention persuasive of Examiner error. In particular, we disagree with the Examiner in concluding use of the phrase "such that" renders inconsequential to the issue of patentability the 6 Appeal2015-000005 Application 12/501,416 relationship expressed by the equation that follows. Instead, claim 2 requires the step of decomposing be structured so as to generate first and second derived matrices D 1 and D2 from a primary matrix T according to the relationship T=Dl +D2. Thus, rather than an intended use, the disputed equation recites the required functionality of or method performed by the decomposing step. Furthermore, the Examiner provides insufficient evidence or reasoning to persuade us Bui's factorization techniques for decomposing a matrix into the product of matrices teaches or suggests decomposing a matrix into the sum of two matrices. Although the Examiner may be correct in finding multiplication, at least in general, can be performed by repeated additions, we find insufficient evidence that matrix multiplication can likewise be performed by repeated additions of a matrix. Therefore, on the record before us, we cannot sustain the rejection of dependent claim 2, nor, for the same reason, can we sustain the rejection of dependent claims 14 and 19. Because claims 3-5, 15, 16, 20, and 21 further depend from claims 2, 14, or 19, we likewise do not sustain the rejection of these claims. DECISION The Examiner's decision to reject claims 1, 11-13, 18, and 23 is affirmed. The Examiner's decision to reject claims 2-5, 14--16, and 19-21 is reversed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l )(iv). 7 Appeal2015-000005 Application 12/501,416 AFFIRMED-IN-PART 8 Copy with citationCopy as parenthetical citation
