ISSUES Rejection of claims 1-4, 6, 8, 9, 12, and 24 under 35 U.S.C. § 102(b) as being anticipated by IBM Technical Disclosure Bulletin Independent claim 1 and dependent claims 2-4, 6, 8, 9, and 12 Appellant argues on pages 10-12 of the Appeal Brief that the Examiner’s rejection of claims 1-4, 6, 8, 9, and 12 is in error. Appellant 3 Appeal 2009-004155 Application 10/739,471 argues that the IBM reference does not disclose a piezoelectric transducer with a pair of adjacent regions that are connected “in a manner that provides increased voltage sensitivity of the transducer to bending wave vibrations relative to the plurality of poled piezoelectric regions if homogeneously poled.” App. Br. 11. Appellant additionally argues that the IBM reference does not disclose a piezoelectric transducer that measures bending wave vibrations. App. Br. 11-12. Thus, Appellant’s contentions with respect to claims 1-4, 6, 8, 9, and 12 present us with two issues. (1) Does the IBM reference disclose a piezoelectric transducer with a pair of adjacent regions that are connected in a manner that provides increased voltage sensitivity of the transducer to bending wave vibrations relative to the plurality of poled piezoelectric regions if homogeneously poled? (2) Does the IBM reference disclose a piezoelectric transducer that measures bending wave vibrations? Rejection of claims 5, 7, 10, 11, 13, and 24 Appellant argues on pages 12-14 and 19-20 of the Appeal Brief that the Examiner’s rejections of claims 5, 7, 10, 11, 13, and 24 are in error. Appellant presents the same arguments that were made with respect to claims 1-4, 6, 8, 9, and 12. App. Br. 12-14 and 19-20. Thus, Appellant’s arguments with respect to claims 5, 7, 10, 11, 13, and 24 present us with the same issues as claims 1-4, 6, 8, 9, and 12. 4 Appeal 2009-004155 Application 10/739,471 Rejection of claims 14-20 and 25 under 35 U.S.C. § 103(a) as being unpatentable over Kobayashi in view of IBM Independent claim 14 and dependent claims 15-20 Appellant argues on pages 14-16 of the Appeal Brief and pages 10-14 of the Reply Brief that the Examiner’s rejection of independent claim 14 and dependent claims 15-20 is in error. Appellant argues that the motivation to combine Kobayashi with IBM is in error. App. Br. 15; Reply Br. 13. Thus, Appellant’s arguments with respect to claims 14-20 present us with the issue: Has the Examiner erred in combining Kobayashi with IBM? Independent claim 25 Appellant argues on pages 16-17 of the Appeal Brief that the Examiner’s rejection of independent claim 25 is in error. Appellant presents the same arguments discussed above with respect to independent claim 14. App. Br. 16-17. Thus, Appellant’s arguments with respect to the Examiner’s rejection of claim 25 presents us with the same issues as claim 14. Rejection of claims 14 and 21-23 under 35 U.S.C. § 103(a) as being unpatentable over Sullivan in view of IBM Appellant argues on pages 17-19 of the Appeal Brief and page 10 of the Reply Brief that the Examiner’s rejection of independent claim 14 and dependent claims 21-23 is in error. Appellant argues that the motivation to combine Sullivan with IBM is in error. App. Br. 17. Thus, Appellant’s arguments with respect to claims 14 and 21-23 present us with the issue: Has the Examiner erred in combining Sullivan with IBM? 5 Appeal 2009-004155 Application 10/739,471 FINDINGS OF FACT IBM 1. IBM discloses a transducer that monitors and analyzes interference between a magnetic recording disk and a read-write head. ¶ 1. 2. The transducer includes a piezoelectric element 1, a magnetic head slider 2, two sensing electrodes (3 and 4), and a bottom electroded surface 5. ¶ 2 and (the sole) Fig. 3. The sensing electrodes (3 and 4) are bonded to the top of the piezoelectric element 1. As a result, both halves are active and are oppositely poled. ¶ 2 and (the sole) Fig. 4. This configuration creates a significant improvement in performance as a result of “its high degree of symmetry so that only three mechanical modes are sensed in a broad range of frequencies.” Other sensed modes can be substantially reduced by electrical filtering in order to create more sensitive measurements. ¶ 3. Kobayashi 5. Kobayashi discloses a piezoelectric sensor that detects vibrations. Col. 3, ll. 30-32. 6. In order to effectively detect vibrations, Kobayashi recognizes that the piezoelectric elements must conform to a particular shape. Col. 2, ll. 4-6. PRINCIPLES OF LAW Office personnel must rely on Appellants’ disclosure to properly determine the meaning of the terms used in the claims. Markman v. 6 Appeal 2009-004155 Application 10/739,471 Westview Instruments, Inc., 52 F.3d 967, 980 (Fed. Cir. 1995) (en banc). “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed. Cir. 2002) (internal quotation marks and citations omitted). Where, as here, the claimed and prior art products are identical or substantially identical, or are produced by identical or substantially identical processes, the PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his claimed product. Whether the rejection is based on "inherency" under 35 USC 102, on "prima facie obviousness" under 35 USC 103, jointly or alternatively, the burden of proof is the same, and its fairness is evidenced by the PTO's inability to manufacture products or to obtain and compare prior art products. In re Best, 562 F.2d 1252, 1255 (C.C.P.A. 1977). ANALYSIS Rejection of claims 1-4, 6, 8, 9, 12, and 24 under 35 U.S.C. § 102(b) as being anticipated by IBM Technical Disclosure Bulletin Independent claim 1 and dependent claims 2-4, 6, 8, 9, and 12 Appellant’s arguments have not persuaded us of error in the Examiner’s rejection of claims 1-4, 6, 8, 9, and 12. Claim 1 recites “the pairs of adjacent regions connected in a manner that provides increased voltage sensitivity of the transducer to bending wave vibrations relative to the plurality of poled piezoelectric regions if homogeneously poled.” Claims 2-4, 6, 8, 9, and 12 depend upon claim 1, but were not argued separately. Therefore, claim 1 is selected to represent this group. 7 Appeal 2009-004155 Application 10/739,471 Appellant argues on page 11 of the Appeal Brief that the IBM reference does not teach that the “regions are connected ‘in a manner that provides increased voltage sensitivity of the transducer to bending wave vibrations relative to the plurality of poled piezoelectric regions if homogeneously poled.’” Appellant argues that since the IBM reference senses only three mechanical modes, the IBM transducer actually decreases sensitivity. App. Br. 11. We do not find this argument to be persuasive. The Examiner correctly finds that the IBM reference discloses a piezoelectric element with two halves. Ans. 10. The halves are connected in series and one half is oppositely poled with respect to the other. Ans. 10. In this regard, the Examiner logically explains that the IBM transducer and Appellant’s transducer are structurally similar and, as a result, would inherently have the same increased voltage sensitivity to vibrations. Ans. 10-11. This logical finding by the Examiner is reinforced by Appellant’s disclosure that “any side-by-side configuration of piezoelectric devices or regions connected in series with pole reversal through the series connections will result in increased voltage sensitivity, particularly to vibration sensing, relative to a single, homogeneously poled transducer having the same overall dimensions and material properties.” Spec. 5:21-24. Where, as here, the claimed and prior art products are identical or substantially identical, the Patent and Trademark Office can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of the claimed product. Whether the rejection is based on inherency under 35 U.S.C. § 102, or on prima facie obviousness under 35 U.S.C. § 103(a), jointly or alternatively, the burden of proof is the same, and its fairness is evidenced by the inability of the Patent and 8 Appeal 2009-004155 Application 10/739,471 Trademark Office to manufacture products or to obtain and compare prior art products. Best, 562 F.2d at 1255. Appellant does not contest with any reasonable specificity the Examiner’s finding that the IBM transducer has the same structure as Appellant’s transducer. Thus, it follows that Appellant has failed to carry his burden of proving that the IBM transducer does not necessarily or inherently possess the contested characteristics of the claim 1 transducer. Appellant additionally argues that the IBM transducer does not measure bending wave vibrations. App. Br. 11-12. Appellant argues that the IBM transducer is used for quality assurance and that because the transducer is not attached to a disk, it is incapable of measuring bending wave vibrations. App. Br. 12. We disagree. As discussed above, the Examiner finds that the IBM transducer has the same structure as Appellant’s transducer and would similarly be able to measure bending wave vibrations. Ans. 10-11. This logical finding by the Examiner is reinforced by Appellant’s disclosure that “vibrations may be due to an impact of the touch implement on the surface, or by frictional movement of the touch implement across the surface.” Spec. 12:2-4. As noted above, when the claimed and prior art products are structurally similar, the burden shifts to Appellant to show that the prior art product does not possess the inherent characteristic. Id. Since Appellant has not shown that the IBM transducer is structurally different from Appellant’s transducer and has not provided sufficient evidence to show that the IBM transducer does not measure bending wave vibrations, the Appellant has failed to meet his burden. 9 Appeal 2009-004155 Application 10/739,471 Accordingly, we sustain the Examiner’s rejection of claim 1 and claims 2-4, 6, 8, 9, and 12 that were grouped with claim 1. Rejection of claims 5, 7, 10, 11, 13, and 24 Appellant’s arguments have not persuaded us of error in the Examiner’s rejections of claims 5, 7, 10, 11, 13, and 24. Independent claim 24 contains similar limitations discussed supra with respect to claim 1. Dependent claims 5, 7, 10, 11, and 13 depend upon and also contain similar limitations discussed supra with respect to claim 1. Appellant’s arguments present the same issues discussed with respect to independent claim 1. App. Br. 12-14 and 19-20. Therefore, we sustain the Examiner’s rejections of claims 5, 7, 10, 11, 13, and 24 for the reasons discussed supra with respect to claim 1. Rejection of claims 14-20 and 25 under 35 U.S.C. § 103(a) as being unpatentable over Kobayashi in view of IBM Independent claim 14 and dependent claims 15-20 Appellant’s arguments have persuaded us of error in the Examiner’s rejection of claims 14-20 and 25. Independent claim 14 recites “a series of poled piezoelectric regions . . . , the poling direction of each region being perpendicular to the surface of the touch plate.” Independent claim 25 recites similar limitations and claims 15-20 depend upon claim 14. Claims 25-20 and 25 were not argued separately. Therefore, claim 14 is selected to represent this group. Appellant argues that the Examiner has not established any motivation to combine Kobayashi with IBM. App. Br. 14. The Examiner concluded that it would have been obvious to combine the references in order to provide transducers with “’improved performance due to its high degree of 10 Appeal 2009-004155 Application 10/739,471 symmetry.’” Ans. 8. However, the IBM reference discloses that the improvement in performance is related to sensing “only three mechanical modes in a broad range of frequencies.” FF 4. In addition, the IBM reference discloses reducing other sensed modes to create more sensitive measurements. FF 4. The reference is silent as to which modes are and are not sensed and which sensing modes are reduced. Therefore, it is not clear whether replacing the Kobayashi transducer with the IBM transducer would exhibit a significant improvement in performance. “That which may be inherent is not necessarily known. Obviousness cannot be predicated on what is unknown.” In re Rijckaert, 9 F.3d 1531, 1534 (Fed. Cir. 1993). Additionally, Kobayashi requires its piezoelectric elements to have a particular shape in order to be effective. FF 6. If one were to modify the piezoelectric element of the IBM reference to have a particular shape as required by Kobayashi, it is unknown whether the new shape would provide the significant increase in performance as claimed. As such, we find that the Examiner erred in combining Kobayashi with IBM and we will not sustain the Examiner’s rejection of independent claim 14 and dependent claims 15- 20. Independent claim 25 Appellant’s arguments have persuaded us of error in the Examiner’s rejection of claim 25. Claim 25 contains similar limitations discussed supra with respect to independent claim 14. Appellant’s arguments present the same issues discussed with respect to independent claim 14. App. Br. 16-17. Therefore, we will not sustain the Examiner’s rejection of claim 25 for the reasons discussed supra with respect to claim 14. 11 Appeal 2009-004155 Application 10/739,471 Rejection of claims 14 and 21-23 under 35 U.S.C. § 103(a) as being unpatentable over Sullivan in view of IBM Appellant’s arguments have persuaded us of error in the Examiner’s rejection of independent claim 14 and dependent claims 21-23. As noted above, independent claim 14 recites “a series of poled piezoelectric regions . . . , the poling direction of each region being perpendicular to the surface of the touch plate.” Claims 21-23 depend upon claim 14 and were not argued separately. Therefore, claim 14 is selected to represent this group. Appellant argues that the Examiner has not established any motivation to combine Sullivan with IBM. App. Br. 17. The Examiner concluded that it would have been obvious to combine the references in order to provide transducers with “’improved performance due to its high degree of symmetry.’” Ans. 9. However, as discussed above, it is not clear whether replacing the Sullivan transducer with the IBM transducer would have been expected to exhibit a significant improvement in performance. “That which may be inherent is not necessarily known. Obviousness cannot be predicated on what is unknown.” In re Rijckaert, 9 F.3d 1531, 1534 (Fed. Cir. 1993) As such, we find that the Examiner erred in combining Sullivan with IBM and we will not sustain the Examiner’s rejection of independent claim 14 and dependent claims 21-23. CONCLUSION Appellant has not persuaded us that the Examiner erred in finding that the IBM reference discloses a piezoelectric transducer with a pair of adjacent regions that are connected in a manner that provides increased voltage 12 Appeal 2009-004155 Application 10/739,471 sensitivity of the transducer to bending wave vibrations relative to the plurality of poled piezoelectric regions if homogeneously poled. Appellant has not persuaded us that the Examiner erred in finding that the IBM reference discloses a piezoelectric transducer that measures bending wave vibrations. Appellant has persuaded us that the Examiner erred in combining Kobayashi with IBM. Appellant has persuaded us that the Examiner erred in combining Sullivan with IBM.
