Claims 1, 2, 13, 24, and 25 are rejected under 35 U.S.C. § 102(a)(l) as anticipated by Fliege. Claim 5 is rejected under 35 U.S.C. § 103 as unpatentable over Miura and Reul. Claims 9, 13, and 15-18 are rejected under 35 U.S.C. § 103 as unpatentable over Miura and Fliege. Claim 19 is rejected under 35 U.S.C. § 103 as unpatentable over Miura, Fliege, and Armiroli. Claim 20 is rejected under 35 U.S.C. § 103 as unpatentable over either Miura or Fliege. Claim 23 is rejected under 35 U.S.C. § 103 as unpatentable over either Miura or Fliege and Iwashita. ANALYSIS Claims 1, 3, 4, 6-8, 10, 11, and 24-Anticipation-Miura Appellants argue the patentability of claims 1, 4, 6-8, 10, 11, and 24 as a group, and claim 3 separately. App. Br. 7-9. We select claim 1 as representative of the group, and decide the appeal of these claims on the basis of claim 1 alone. 37 C.F.R. § 4I.37(c)(l)(iv). Claim 3 will be discussed separately. 2 The Examiner's rejections of claim 20 under 35 U.S.C. § 101, and claims 1, 2, 14, 18, and 24 under 35 U.S.C. § 112(b), have been withdrawn. Ans. 7. 3 Appeal2017-006079 Application 14/2 71,771 Claim 1 The Examiner finds that Miura discloses the clutch system of claim 1, and specifically finds that Miura's load sensor 10 corresponds to the claimed load sensor that is positioned remotely from a front face of the thrust bearing and configured to measure a load exerted against said front face of said thrust bearing. Final 4--5; Ans. 7-8 (citing Miura, Fig. 2). According to the Examiner, "[a] load is generated at pressure plate 20, moves through the front face and holding plate 6 into the elastic member 8 and is finally measured by the load sensor." Ans. 8-9. Appellants respond: [T]he load sensor 10 is positioned to perceive a change in the biasing force of a coil spring 8 in order to detect an amount of wear on the clutch disk 20. A change in the biasing force of the coil spring 8 is caused by an axial position change of the clutch release bearing 5, which is the result of wear on the clutch disk 20. It follows from these teachings that the load sensor 10 of Miura has nothing to do with measuring loads exerted against the clutch release bearing 5. Instead, Miura is focused on quantifying axial displacement of the clutch release bearing 5. Reply Br. 2. We are not persuaded that the Examiner erred in rejecting claim 1 as anticipated by Miura. While Miura may be "focused on" quantifying axial displacement of the clutch release bearing 5, that does not show error in the Examiner's analysis that the load measured by the load sensor is the same as the load perceived at the front face of the clutch release bearing. Accordingly, we sustain the Examiner's rejection of claims 1, 4, 6-8, 10, 11, and 24 as anticipated by Miura. Claim 3 Appellants argue that Miura does not disclose the limitation in claim 3 requiring the front face of the thrust bearing to be rotatable and the rear face 4 Appeal2017-006079 Application 14/2 71,771 of the bearing to be nonrotatable. App. Br. 7-8. The Examiner responds with a detailed explanation, using an annotated version of Figure 2 of Miura, supporting the finding that the front face of Miura's thrust bearing is rotatable and the rear face is nonrotatable. Ans. 9-10. Appellants do not respond to this explanation, much less show it to be erroneous. Accordingly, we sustain the Examiner's rejection of claim 3 as anticipated by Miura. Claims 1, 2, 13, 24, and 25-Anticipation-Fliege Claim 1 The Examiner finds that Fliege discloses the clutch system of claim 1, and specifically finds that Fliege's sensor 16" is positioned remotely from the front face of thrust bearing 40 and is configured to measure a load exerted against the front face. Final Act. 5 ( citing Fliege, Fig. 8). The Examiner further explains that: Although Fliege does disclose that a pressure force on element 152 is detected by load sensor 16", paragraph [0065] also discloses, "the force transmission path between the actuation piston 26 and the thrust plate 152 accordingly extends along the force measuring element 16" ... " (e.g., paragraph [0065]). In other words, the pressure force exerted on the thrust plate is detected at the thrust bearing, as the bearing is in the force transmission path between the load sensor and 152. The load sensor 16" detects a load at thrust bearing 40, in order to establish the pressure force at 152. Ans. 11. Appellants respond that "[ n ]either Figure 8 nor the description accompanying this figure evidences that the inner portion 170 of the thrust plate 152 exerts a force on a front face of the pivot bearing 40." Reply Br. 3. According to Appellants, "[t]he inner portion 170 appears to extend through a bore of the pivot bearing, in which case the force transmission path would not pass through the front face." Id. 5 Appeal2017-006079 Application 14/2 71,771 We are not persuaded that the Examiner erred in rejecting claim 1 as anticipated by Fliege. Contrary to Appellants' assertions, Fliege does disclose that inner portion 170 of thrust plate 152 exerts a force on a face of thrust bearing 40. Specifically, Fliege discloses that actuation piston 26 "acts at the portion 170 [of thrust bearing 152] with pivot bearing 40." Fliege ,r 64. Fliege further discloses that bearing 40 is pretensioned "against the inner portion 170." Id. (emphasis added). Based on these disclosures- as well as Figure 8, which depicts thrust bearing 40 situated between portion 170 and load sensor 16--we agree with the Examiner that thrust bearing 40 is in the force transmission path between force measuring element 16" [actuation piston 26] and portion 170 of thrust bearing 152. Therefore, the force measured "by load sensor 16" would be the same as that exerted by the front face of thrust bearing 40 against portion 170. Accordingly, we sustain the rejection of claim 1 as anticipated by Fliege. Claims 2, 13, and 24 Claims 2 and 24, which depend from claim 1, are not separately argued. 3 Independent claim 13 is similar to claim 1, and Appellants raise the same unpersuasive argument in support of the patentability of claim 13 as for claim 1. App. Br. 8-9. Thus, we also sustain the rejection of claims 2, 13, and 24 as anticipated by Fliege. 3 Appellants do raise an argument specific to claim 2 in the Reply Brief. Reply Br. 3--4. However, Appellants do not provide good cause for why this argument was not raised in the Appeal Brief. Therefore, it will not be considered. 3 7 C.F .R. §41.41 (b )(2). 6 Appeal2017-006079 Application 14/2 71,771 Claim 25 Appellants raise additional arguments for independent claim 25. Claim 25 reads as follows: 25. A clutch system, comprising: a concentric slave cylinder including a housing and a guide protruding from said housing; a thrust bearing including a bore, said guide extending into said bore; a load sensor received over said guide and configured to measure a load exerted against said thrust bearing; and a spring positioned between said thrust bearing and said housing, said spring configured to exert a biasing force against said thrust bearing. The Examiner asserts that Figure 1 of Fliege discloses all of the limitations of claim 25, and specifically asserts that "load sensor ( 16) [is] received over said guide and configured to measure a load exerted against said thrust bearing." Final Act. 6. Appellants first argue that there is no support for the Examiner's finding that load sensor 16 is capable of measuring a load exerted against the thrust bearing 40. App. Br. 9. Instead, Appellants argue, "measuring arrangement 16 controls the stroke of the friction clutch but does not measure any loads exerted against the clutch." In the Answer, the Examiner explains how paragraph 45 of Fliege supports the finding that measuring element 16 "transmits a signal based on the axial displacement of element 82 that is indicative of the load present on pivot bearing 40 during engagement and disengagement." Ans. 13-14. Appellants do not address this explanation in the Reply Brief. Having considered Appellants argument, as well as the Examiner's response, we are not persuaded that the Examiner erred in finding that pivot bearing 40 7 Appeal2017-006079 Application 14/2 71,771 measures the load on the thrust bearing during engagement and disengagement. Appellants next argue that "the alleged load sensor 16 of Fliege is not 'received over' the alleged guide 30 of the actuation cylinder." App. Br. 10. According to Appellants, "the measuring arrangement 16 is housed inside a housing 72 that is completely remote from the alleged guide 30." Id. The Examiner counters that, as depicted in Figure 1, measuring arrangement 16 "is above [guide] 30 and therefore received over." Ans. 14. In response, Appellants assert the Examiner's interpretation of the phrase "received over" to mean "above" is not reasonable. Reply Br. 5. Appellants do not identify why the Examiner's claim construction is unreasonable. Rather, Appellants provide their own claim construction of the term, arguing, "[i]t is evident from the subject specification and Figures that to be 'received over' the guide, the sensor must accommodate the guide within its bore." Id. ( citing Spec. ,r 59, Figs. 3, 5, and 6). Though Appellants cite to the Figures and Specification, they provide little to no discussion of their evidence or why the evidence supports their claim construction. We have considered Appellants' argument but are not apprised of Examiner error in its interpretation of "received over." During prosecution, claims are given their broadest reasonable interpretation. In re Bigio, 3 81 F.3d 1320, 1324 (Fed. Cir. 2004). In doing so, we give claim terms their ordinary meanings in the art, unless narrowed by an Applicants' Specification, e.g., narrowed by an express definition or by an implicit definition via the term's usage. Phillips v. AWH Corp., 415 F.3d 1303, 1316, 1321 (Fed. Cir. 2005) (en bane). The Specification neither expressly nor implicitly defines the term "received over." Paragraph 59, which Appellants 8 Appeal2017-006079 Application 14/2 71,771 cite in support of its interpretation, does not use the term at all. Instead, this paragraph and the figures on which Appellants rely describe non-limiting embodiments of the invention. Although giving claims their broadest reasonable interpretation must take into account any definitions given in the Specification, In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997), it is improper to read into the claims any limitations appearing in specific embodiments described in the Specification. In re Zietz, 893 F.2d 319, 321- 22 (Fed. Cir. 1989). Appellants claim construction would have us improperly read terms into the claim. We note that claim 25 also recites "a thrust bearing including a bore, said guide extending into said bore." This term clearly means what Appellants argue "received over" to mean: the thrust bearing "accommodate[s] the guide within its bore." Reply Br. 5. If Appellants wanted the claim to require the sensor to accommodate the guide within its bore as well, they could easily have used the same language. Indeed, the fact that they used different language suggests that they meant "received over" to mean something else. See Helmsderfer v. Bobrick Washroom Equip., Inc., 527 F.3d 1379, 1382 (Fed. Cir. 2008) ("Our precedent instructs that different claim terms are presumed to have different meanings."). Thus, we are not persuaded that the Examiner's construction of "received over" is unreasonable or otherwise erroneous. Accordingly, we sustain the Examiner's rejection of claim 25 as anticipated by Fliege. Claim 5-Unpatentable over Miura and Reul Claim 5 depends from claim 4. Claim 4 depends from claim 1 and additionally requires the clutch system of claim 1 to comprise a concentric slave cylinder that includes "a housing and a guide that protrudes from said 9 Appeal2017-006079 Application 14/2 71,771 housing." Claim 5 recites that "said guide extends through a bore of each of said thrust bearing and said load sensor." The Examiner states that "it is unclear from the showing in Miura whether the load sensor is annular such that the guide would extend through a bore in the bearing and sensor." Final Act. 7. The Examiner contends, however, that Reul teaches "a similar device" with "a load sensing device 16 that is annular, and guide 22 extends through a bore in the bearing 12 and the sensing device 16." Id. In the Answer the Examiner explains that spring plate 42 "is part of the sensor device and can be seen to be annular in at least FIG. 4." Ans. 15. The Examiner further asserts that "[ s ]ince this configuration of load sensor is known, it would not have been a patentable modification of Miura to make the sensor 10 of an annular configuration such that the guide would extend therethrough," and doing so "would have yielded predictable results; namely, an operable clutch release system." Final Act. 7. Appellants respond that "no ... 'reasoned' statements have been articulated to support the legal conclusion of obviousness." Reply Br. 6. Appellants assert that "it is never explained how the proposed modification would help achieve an operable clutch release system any more than the configuration of Miura already does." Id. Appellants further assert that "the proposed modification to make the sensor 10 annular has no rational basis in this context, and the annular shape could render the sensor 10 inoperable for perceiving changes in the biasing force of the coil spring 8." Id. We have considered Appellants' arguments but are not apprised of Examiner error. First, contrary to Appellants' assertion, the Examiner has articulated a reason, with rational underpinning, for combining Miura and Reul, substituting Reul's known annular load sensor for Miura's load sensor 10 Appeal2017-006079 Application 14/2 71,771 would have yielded predictable results. See KSR Int'! v. Teleflex Inc., 550 U.S. 398, 416 (2007) ("when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result" to be nonobvious) (citing United States v. Adams, 383 U.S. 39, 50-51 (1966)). Second, Appellants assertion that this substitution could render Miura's sensor inoperable for its intended purpose is not supported by evidence or persuasive argument, and is therefore unpersuasive of Examiner error. Accordingly, we sustain the Examiner's rejection of claim 5 as unpatentable over Miura and Reul. Claims 9, 13, and 15-18-Unpatentable over Miura and Fliege The Examiner argues that it would have been obvious to position Miura's load sensor between the spring and bearing, as taught by Fliege, "to yield a more direct measurement of load on the bearing race." Final Act. 8. Appellants responds that Miura teaches away from this modification because Miura teaches mounting load sensor 10 on a spring seat of elastic member 8 to detect the compression load on the spring, and "[i]t is unclear if this desired measurement would still be possible if the load sensor 10 were moved to a location between the spring 8 and the bearing 5." App. Br. 11. We are not persuaded that Miura teaches away from this modification, however, because Appellants do not point to any part of Miura that criticizes, discredits or discourages the modification. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004) ("the prior art's mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed."). Further, Appellants do 11 Appeal2017-006079 Application 14/2 71,771 support with evidence or persuasive argument its assertion that it would not be possible to measure the compression load on the spring if Miura's clutch was modified as proposed. Appellants also argue that the proposed modification "would require a significant redesign and reconfiguration" of Miura's clutch. Id. Again, however, this argument is unsupported, and therefore unpersuasive. Accordingly, we sustain the Examiner's rejection of claims 9, 13, and 15-18 as unpatentable over Miura and Fliege. The Remaining Rejections Appellants do not present substantive arguments for claims 19, 20, or 23, but instead rely on arguments previously made and found unpersuasive. App. Br. 11-12. Therefore, we sustain the Examiner's rejections of these claims. DECISION For the above reasons, the Examiner's rejections of claims 1-11, 13, 15-20, and 23-25 are affirmed. 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). AFFIRMED 12 Copy with citationCopy as parenthetical citation
