HASTINGS, and GEORGE C. BEST, Administrative Patent Judges. BEST, Administrative Patent Judge. DECISION ON APPEAL Appeal 2012-000756 Application 11/435,495 2 On February 14, 2011, the Examiner finally rejected claim 8 of Application 11/435,495 under 35 U.S.C. § 102(b) as anticipated and claims 1-4 and 6-9 under 35 U.S.C. § 103(a) as obvious. Appellants1 seek reversal of these rejections pursuant to 35 U.S.C. § 134(a). We have jurisdiction under 35 U.S.C. § 6(b). For the reasons set forth below, we AFFIRM-IN-PART. BACKGROUND Micromachined cantilevers can be used to send chemical and biological materials of interest for defense and pollution control applications. Spec. ¶ [0008]. The micromachined cantilevers can be manufactured in large numbers using techniques similar to those used to make electronic circuits. Id. Figure 1 of the ’495 application is reproduced below. Figure 1 is a schematic side view of a micromachined cantilever system. Id. at ¶ [0012]. Cantilever 11 extends from a body 12. Id. at ¶ [0015]. The cantilever has an extension length l from body 12. Id. Adsorption of a target 1 Lawrence Livermore National Security, LLC and the United States of America are the real parties in interest (App. Br. 3). Appeal 2012-000756 Application 11/435,495 3 species Γ on the top surface of the cantilever produces changes in the cantilever’s surface stresses σ + and σ –, which induces a measureable deflection Δz. Id. These devices, however, are sensitive to a wide range of stimuli, which can make it difficult to extract meaningful signals from the cantilevers. Id. at ¶ [0008]. The ’495 application describes processes for enhancing the signal produced by a cantilever sensor array. Id. at ¶¶ [0003], [0009]. Claim 1 is representative of the ’495 application’s claims and is reproduced below: Claim 1. A method of signal enhancement of an L-element cantilever sensor array, comprising the steps of: providing a micromachined cantilever with a cantilever length l, a deflection Δz, a surface stress σ + and σ - , and a surface concentration of target species Γ; detecting a parameter utilizing deflection of said micromachined cantilever with said cantilever length l, said deflection Δz, said surface stress σ + and σ - , and said surface concentration of target species Γ: modeling the deflection of said micromachined cantilever using said cantilever length l, said deflection Δz, said surface stress σ + and σ - ,and said surface concentration of target species Γ and producing a deflection model for detecting the parameter; measuring differential surface stress Δσ (= Δσ + - Δσ -) of said micromachined cantilever and producing a signal representing said differential surface stress, wherein said step of measuring differential surface stress Δσ (= Δσ + - Δσ -) of said micromachined cantilever and producing a signal representing said deflection provides measured data containing noise and including the step of removing said noise from said measured data; and Appeal 2012-000756 Application 11/435,495 4 comparing said signal representing said differential surface stress with said deflection model for detecting the parameter to produce the signal enhancement of an L-element cantilever sensor array.

The Examiner finally rejected claim 8 under 35 U.S.C. § 103(a) as obvious over the combination of Dareing4 and Marie. FR. 7. DISCUSSION Rejection 1. The Examiner rejected claim 8 as anticipated by Marie. Claim 8 is reproduced below: 2 R. Marie et al., Adsorption Kinetics and Mechanical Properties of Thiol- Modified DNA-Oligos on Gold Investigated by Microcantilever Sensors, 91 ULTRAMICROSCOPY 29-36 (2002). 3 T.A.

A method of detecting a biological agent utilizing deflection of a micromachined cantilever that represents the biological agent being detected, consisting of the steps of: modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent, measuring differential surface stress Δσ (= Δσ + - Δσ -) of the micromachined cantilever and producing a signal representing said differential surface stress, and comparing said signal representing said differential surface stress with said deflection model for detecting the biological agent. (App. Br. 56 (Claims App’x)). Appellants argue that the Examiner erred by (a) failing to give weight to the transitional phrase “consisting of” (App. Br. 20), (b) incorrectly interpreting the claim element “modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent” (id. at 22), (c) incorrectly interpreting the claim element “measuring differential surface stress, Δσ (= Δσ + - Δσ -) of the micromachined cantilever and producing a signal representing said differential surface stress” (id. at 23), and (d) finding that Marie describes the step of comparing the signal representing the differential surface stress with the deflection model (id. at 19). We address these arguments seriatim. First, Appellants argue that the Examiner did not give weight to the transitional phrase “consisting of” and that Marie does not anticipate claim 8 because it discloses additional steps in its method for detecting a biological substance (App. Br. 20-22). “It is . . . well understood in patent usage that ‘consisting of’ is closed-ended and conveys limitation and exclusion.” CIAS, Inc. v. Alliance Gaming Corp., 504 F.3d 1356, 1361 (Fed. Cir. 2007) (citing Appeal 2012-000756 Application 11/435,495 6 Norian Corp. v. Stryker Corp., 363 F.3d 1321, 1331 (Fed. Cir. 2004) (“‘consisting of’ is a term of patent convention meaning that the claimed invention contains only what is expressly set forth in the claim . . . [however] it does not limit aspects unrelated to the invention”); In re Gray, 53 F.2d 520 (CCPA 1931) (the use of the claim term “consists” is limited to the claim’s enumerated alloy metals without other elements, unlike the term “comprising” which permits the inclusion of other metals than those “claimed”). Because the Examiner described Marie’s allegedly anticipatory teaching as consisting of five steps (Ans. 4-5), while claim 8’s method consists of only three steps, Appellants argue that the Examiner erred in finding that Marie anticipates claim 8 (App. Br. 16-17, 20-22; Reply Br. 2- 3). We are not persuaded by Appellants’ arguments. The “additional steps” identified by the Examiner are (a) providing a micromachined cantilever and (b) detecting a parameter utilizing deflection of the micromachined cantilever (Ans. 4-5). As the Examiner argues (id. at 10-11), claim 8 assumes the existence of a micromachined cantilever and necessarily includes detecting a parameter—in this case, the concentration of the biological agent—using the deflection of the micromachined cantilever. Neither of the alleged “additional steps” adds to the steps specifically recited in claim 8. Thus, the Examiner did not err by ignoring the transitional phrase. Second, Appellants argue that the Examiner erred by misinterpreting the claim phrase “modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent” (App. Br. 22). Appellants further argue that when this claim element is properly Appeal 2012-000756 Application 11/435,495 7 construed, it is clear that Marie does not describe a process that includes this step (Id.). This argument also is unpersuasive. During examination, claim terms are given their broadest reasonable construction consistent with the Specification. In general, words used in a claim are accorded their ordinary and customary meaning. Honeywell Int’l Inc. v. Universal Avionics Sys. Corp., 488 F.3d 982, 992 (Fed. Cir. 2007). The “broadest reasonable interpretation” standard does not prejudice the applicant, who has the ability to correct errors in claim language and to adjust the scope of claim protection as needed during prosecution by amending the claims. In re Morris, 127 F.3d 1048, 1053-54 (Fed. Cir. 1997); In re Yamamoto, 740 F.2d 1569, 1571–72 (Fed. Cir. 1984). In this case, Appellants argue that the Examiner erred by “not giv[ing] effect to Appellants’ specification and drawings in interpreting the meaning” of this claim element (App. Br. 22). Appellants clearly state their belief that [h]ad Appellants’ specification and drawings been correctly used to interpret the meaning of the claim element/step “modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent” it would be clear that the Marie reference does not anticipate Appellants’ claim 8. The Marie reference does not discloses, [sic] either expressly or under principles of inherency, Appellants’ “modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent” claim element/step of claim 8. (Id.). Appellants, however, never provide what they contend to be a proper claim construction. We have carefully reviewed Appellants’ briefs and the ’495 application’s Specification. Based upon our review, we surmise that Appellants are asking us to read limitations into claim 8 from the preferred Appeal 2012-000756 Application 11/435,495 8 embodiments that would distinguish the modeling described in Marie from the claimed modeling because Marie used the Langmuir equation as the basis for its modeling. However, (1) reading limitations from the preferred embodiments into the claims is improper, Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005), (2) Appellants were free to amend their claims to state the metes and bounds of their invention more precisely, see Morris, 127 F.3d at 1053- 54, and (3) the Examiner correctly applied the broadest reasonable claim construction in view of the ’495 application’s Specification. We, therefore, conclude that the Examiner did not err in finding that Marie described the claimed step of “modeling the deflection of the micromachined cantilever producing a deflection model for detecting the biological agent.” Third, Appellants argue that the Examiner incorrectly interpreted the claim limitation of “measuring differential surface stress Δσ (= Δσ + - Δσ -) of the micromachined cantilever and producing a signal representing said differential surface stress” (App. Br. 23). Appellants assert that the Examiner erred by failing to “give effect to Appellants’ specification and drawings in interpreting” this claim step and that if the Examiner had properly construed this claim limitation, it would be clear that Marie does not describe this step (Id.). This argument is not persuasive for the same reasons we found Appellants’ arguments concerning the modeling limitation discussed above. Once again, Appellants fail to provide an actual claim construction that encompasses the measuring method described in the ’495 application’s Specification but which does not encompass Marie’s disclosed method of measuring changes in the differential surface stress. Furthermore, we are not convinced that Appellants could do so, as Marie describes a method of Appeal 2012-000756 Application 11/435,495 9 measuring changes of the differential surface stress that is more direct than Appellants’ deflection measurements. Marie 30 (describing use of Wheatstone bridge configuration sensor system). We are not convinced that the Examiner construed this claim element in an unreasonably broad manner or erred in finding that Marie described the process of measuring changes in the differential surface stress. Fourth, Appellants argue that Marie does not disclose, either expressly or under the principles of inherency, the step of “comparing said signal representing said differential surface stress with said deflection model for detecting the biological agent” (App. Br. 19). This argument is not persuasive. As the Examiner found (Ans. 5, 11- 12), Figures 3 and 5 of Marie show that the Langmuir isotherm neatly fits the measured differential surface stress. Marie further describes changes in the surface coverage parameter θ as being proportional to the induced changes in surface stress, Marie 32-33, which, in turn, is proportional to the cantilever’s deflection, id. at 30. Thus, the Examiner did not err in finding that Marie describes comparing the signal representing the differential surface stress with the deflection model. Rejection 2. The Examiner finally rejected claims 1-4, 6, 7, and 9 under 35 U.S.C. § 103(a) as obvious over the combination of Marie and Betts. Appellants present separate arguments for the patentability of claims 1, 2, and 9. The patentability of the remaining claims subject to this rejection will stand or fall with claim 2, from which they depend. 37 C.F.R. § 41.37. Claim 1. Appellants argue that the Examiner erred in concluding that claim 1 is obvious over the combination of Marie and Betts because (a) neither Marie nor Betts describe or suggest several limitations recited in claim 1 (App. Br. 33-34), (b) a person of ordinary skill in the art would not Appeal 2012-000756 Application 11/435,495 10 have had a reasonable expectation of success in combining Marie and Betts (id. at 39), (c) the Examiner did not provide a reason for combining Marie and Betts (id.), and (d) the Examiner erred in construing claim 1’s “measuring” and “modeling” limitations (id. at 40-41). We do not find these arguments persuasive. First, Appellants’ arguments regarding the allegedly missing claim limitations are substantively the same as the arguments discussed in Rejection 1 (compare App. Br. 18-19 with App. Br. 33-34). We find these arguments unpersuasive for the reasons stated above. Second, Appellants argue that a person of ordinary skill in the art would not have had a reasonable expectation of success in combining the descriptions of Betts and Marie to arrive at the claimed invention (id. at 39). Appellants base this argument on the alleged failure of Betts and Marie to describe or suggest every limitation recited in claim 1 (id.). Because we do not agree that Betts and Marie are defective in the manner argued by Appellants, we find this argument to be unpersuasive for the discussed above. Third, Appellants argue that “[t]he Examiner has not provided reasons for combining the nine (9) references to produce the proposed combination of structural elements Appellants’ [sic] apparatus claims 1-4, 6, 7, and 9.” Id. Because the rejection at issue only relies upon two (2) references to produce the proposed combination of steps recited in a method claim, Appellants’ argument is unpersuasive. Furthermore, the Examiner did provide a reason to combine Marie and Betts (Ans. 7-8). Fourth, Appellants argue that the Examiner erred in the interpretation of several of claim 1’s limitations (App. Br. 40-41). In substance, these Appeal 2012-000756 Application 11/435,495 11 arguments are the same as those discussed in connection with Rejection 1 and are unpersuasive for the reasons discussed above. Thus, we affirm the Examiner’s rejection of claim 1 as obvious over the combination of Marie and Betts. Claim 2. Appellants argue that the Examiner erred in concluding that claim 2 would have been obvious to a person of ordinary skill in the art in view of Marie and Betts. Specifically, Appellants argue that (a) Marie and Betts do not describe or suggest every limitation set forth in claim 2 (App. Br. 28-30, 34-36), (b) a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Marie and Betts (id. at 39), (c) the Examiner did not provide a reason for combining Marie and Betts (id.), and (d) the Examiner erred in interpreting claim 2’s “measuring” and “modeling” limitations (id. at 40-41). We are not persuaded by these arguments. First, Appellants argue that the combination of Marie and Betts do not describe or suggest claim 2’s “modeling,” “sensing,” and “comparing” limitations (id. at 28-30). We conclude that Appellants’ arguments regarding the “modeling” and “comparing” limitations are not persuasive for the reasons set forth in our discussion of Rejection 1, supra. We also conclude that Appellants’ arguments regarding claim 2’s “sensing” limitation are not persuasive. Appellants argue that neither Marie nor Betts describe or suggest “sensing said deflection of the micromachined cantilever and producing a signal representing said deflection, wherein said step of sensing the deflection of said micromachined cantilever and producing a signal representing said deflection provides measured data containing noise and including the step of removing said noise from said measured data” as required by claim 2 (id. at 29). Marie describes detecting Appeal 2012-000756 Application 11/435,495 12 the voltage changes induced by changes in the differential surface stress. Marie 30. Furthermore, Marie describes the reduction in noise levels achieved through the inclusion of a reference cantilever and the use of a Wheatstone bridge configuration. Id. Figures 3, 4, and 5 show binding isotherms measured through the detection of this voltage configuration. Id. at 32-33. Betts describes two methods for reducing the noise present in the signal that is used to sense the deflection of the micromachined cantilever. Ans. 7-8. Thus, we are not persuaded that the combination of Marie and Betts does not describe or suggest the claimed “sensing” step. Second, Appellants argue that a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Marie and Betts (App. Br. 39). This argument is not persuasive for the reasons discussed in connection with claim 1, supra. Third, Appellants argue that the Examiner did not provide a reason for combining Marie and Betts (id.). This argument is not persuasive for the reasons discussed in connection with claim 1, supra. Fourth, Appellants argue that the Examiner erred in interpreting claim 2’s “measuring” and “modeling” limitations (id. at 40-41). In substance, these arguments are the same as those discussed in connection with Rejection 1 and are unpersuasive for the reasons discussed above. Thus, we affirm the Examiner’s rejection of claim 2 as obvious over the combination of Marie and Betts. Claim 9. Claim 9 is reproduced below: 9. A method of detecting a chemical or-biological agent [sic, or biological agent] utilizing deflection of a micromachined cantilever that represents the chemical or biological agent being detected employing a model-based signal processing scheme, consisting of the steps of: Appeal 2012-000756 Application 11/435,495 13 providing a process system model including the thermodynamics, chemistry fluidics and statistical uncertainties associated with parameters and noise; providing a measurement system model modeling the deflection of the micromachined cantilever producing a deflection model, along with its parametric uncertainties and noise; providing noise models representing said noise of said measurement system model; and using said process system model, said measurement system model, and said noise models for detecting the chemical or biological-agent by incorporating said models into an optimal signal processing system able to extract both parameters of high interest as well of enhanced the noisy measurements, that is, significantly increasing the final signal-to-noise ratio. (App. Br. 56 (Claims App’x)). Appellants argue that (a) the combination of Marie and Betts does not describe or suggest the “modeling,” “measuring,” “providing noise models,” and “detecting” steps recited in claim 9 (id. at 31-32), (b) a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Marie and Betts (id. at 39), (c) the Examiner did not provide a reason for combining Marie and Betts (id.), and (d) the Examiner failed to give effect to claim 9’s “consisting of” transition and erred in interpreting the “measuring” and “modeling” limitations included in claim 9 (id. at 39-41). Because we find that the Examiner has not identified where the combination of Marie and Betts describe or suggest several of claim 9’s steps, we need only address the first of Appellants’ arguments. The ’495 application’s Specification describes the incorporation of additive, zero-mean, Gaussian noise into the measurement system model. Spec. ¶¶ [0036], [0038]-[0041], Fig. 5. The Examiner does not point to any Appeal 2012-000756 Application 11/435,495 14 portion of either Marie or Betts that describes or suggests the inclusion of any sort of noise in the measurement system model. See Ans. 7-8. In particular, the Langmuir isotherm used by Marie to model binding does not include any description of the observed noise. See Marie 32-33, Fig. 3, Fig. 5. While Betts does describe several ways to reduce the noise in the observed signal, Betts does not describe or suggest the incorporation of noise into the models used to predict the observed deflection models. Thus, the Examiner has not established that claim 9 is prima facie obvious, and we reverse the Examiner’s rejection of claim 9 as obvious over the combination of Marie and Betts. Rejection 3. The Examiner finally rejected claim 8 as obvious over the combination of Dareing and Marie. Appellants argue that this rejection should be reversed because (a) the Examiner erred in interpreting the “measuring” and “modeling” limitations included in claim 9 (App. Br. 50- 52), (b) Dareing and Marie do not describe or suggest a number of claim 8’s limitations (id. at 43-44, 45-47), (c) the Examiner did not give effect to claim 8’s transition phrase “consisting of” (id. at 44-45, 47, 48-50), (d) a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Dareing and Marie (id. at 48), and (e) the Examiner did not provide a reason for combining Dareing and Marie (id.). First, Appellants argue that the Examiner erred in construing claim 8’s modeling and measuring steps. Appellants’ arguments are substantively the same as those we considered and found unpersuasive in our analysis of Rejection 1, supra. We remain unpersuaded by these arguments here. Appeal 2012-000756 Application 11/435,495 15 Second, Appellants argue that neither Dareing nor Marie describe or suggest claim 8’s “modeling,” “measuring,” or “comparing” steps. Appellants’ arguments regarding these limitations are substantively the same as those advanced against Rejection 1. In essence, Appellants argue that neither Dareing nor Marie describe or suggest the specific models and methods described in the ’495 application’s Specification. We are not persuaded that the Examiner erred in finding that Dareing and Marie describe or suggest the steps set forth in claim 8. Third, Appellants argue that the Examiner failed to give effect to claim 8’s use of the transition phrase “consisting of” (App. Br. 44-45, 47, 48-50). Although the Examiner did state that the combination of Dareing and Marie sets forth a five step process (Ans. 9), the Examiner’s argument— made in support of Rejection 1—that the two steps not expressly stated in claim 8 either are assumed by or inherent in claim 8 (id. at 10-11) applies with equal force here. We are not persuaded by Appellants’ arguments for the reasons we discussed in our analysis of Rejection 1. Fourth, Appellants argue that a person of ordinary skill in the art would not have had a reasonable expectation of success in combining Dareing and Marie (App. Br. 48). This argument is not persuasive for the reasons discussed in connection with Rejection 1. Fifth, Appellants argue that the Examiner did not provide a reason for combining Dareing and Marie (id.). This argument is not persuasive for the reasons discussed in connection with Rejection 1. We therefore affirm the Examiner’s rejection of claim 8 as obvious over the combination of Dareing and Marie. Appeal 2012-000756 Application 11/435,495 16 CONCLUSION We affirm the rejection of claim 8 as anticipated by Marie. We also affirm the rejections of claims 1-4, 6, and 7 as obvious over the combination of Marie and Betts. We reverse the rejection of claim 9 as obvious over the combination of Marie and Betts. Finally, we affirm the Examiner’s rejection of claim 8 as obvious over the combination of Dareing and Marie. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). AFFIRMED-IN-PART bar Copy with citationCopy as parenthetical citation
