ST AMEY JR., MARK A. ROLL, and ROBERT H. FERGUSON Appeal 2016-006537 Application 12/139,800 Technology Center 1700 Before LINDA M. GAUDETTE, DONNA M. PRAISS, and AVEL YN M. ROSS, Administrative Patent Judges. GAUDETTE, Administrative Patent Judge. DECISION ON APPEAL 1 Appellants2 appeal under 35 U.S.C. § 134(a) from the Examiner's decision finally rejecting claims 1-5, 7-10, 13-17, and 19-26. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 This Decision includes citations to the following documents: Specification filed June 16, 2008 ("Spec."); Final Office Action dated May 19, 2014 ("Final"); Appeal Brief filed Jan. 9, 2015 ("Br."); and Examiner's Answer dated July 7, 2015 ("Ans."). 2 Appellants identify the real party in interest as Wix Filtration Corp. LLC. Br. 3. Appeal 2016-006537 Application 12/139,800 The invention relates to filter elements for removing impurities from a fluid. Spec. ,r,r 3--4. Figure 9, reproduced below, illustrates a filter element in accordance with an embodiment of the invention. Id. ,r 15 . .. ,.,....,J 1,6&4J ,,.1662 UJ7G,.,' Figure 9, above, is a cross-sectional view of assembled, replaceable filter element 1600. Id. n 19, 33. "[F]ilter element 1600 includes an upper, first end cap 1602, a lower, second end cap 1610, filter media 1604, and a central tube 1608 extending from the second end cap 1610." Id. ,r 33. In the Figure 9 embodiment, central tube 1608 and lower end cap 1610 are unitary, and define a subcomponent of replaceable filter element 1600. Id. ,r 34. This subcomponent is illustrated in greater detail in Figure 8, the relevant portion of which is reproduced below. 2 Appeal 2016-006537 Application 12/139,800 The portion of Figure 8 shown above illustrates a cross-sectional view of central tube 1608 and lower end cap 1610 of replaceable filter element 1600. Id. n 19, 33. Inner surface 1620 includes first surface 1626 having first diameter Cl, and second surface 1628 having second diameter C2. Id. ,r 36. Cl is greater than C2. Id. First and second surfaces 1626, 1628 are demarcated by shoulder portion 1630 that projects radially inwardly toward central axis A-A. Id. Shoulder portion 1630 includes shoulder surface 1632, defined by angle 8 (shown in Figure 6) that is approximately equal to, for example, 135°. Id. ,r 38. Inner surface 1620 is sized and shaped to correspondingly engage a standpipe (see, e.g., standpipe 1575 in Figure 5). Id. ,r 41. "Functionally, the shoulder portion 1630 acts as a projectionless standpipe actuator as the shoulder surface 1632 contacts and engages the axial surface portion 1577 of the valve." Id.; see Figure 5 (illustrating axial surface portion 1577). Of the appealed claims, claims 1 and 13 are independent. Claim 1 recites "[a] sub-assembly of a replaceable filter element." Claim 13 recites "[a] filter element" and includes limitations similar to those recited in claim 1, but also requires an additional end cap and filter media extending between the end caps. For reference, claim 1 is reproduced below. 1. A sub-assembly of a replaceable filter element interfaceable with a standpipe, comprising: an end cap defining a first central opening; a central tube integrally connected to the end cap and circumscribing the central opening, wherein the central tube includes: a proximal end that is integrally connected to the end cap, a distal end opposite the proximal end, wherein the distal end forms a second central opening, an outer side surface extending between the proximal end and the distal end, wherein the outer side surface extends substantially perpendicularly 3 Appeal 2016-006537 Application 12/139,800 with respect to an upper swf ace of the end cap for an entire length of the central tube from the proximal end to the distal end, and an inner side surface extending between the proximal end and the distal end, wherein the inner side surface forms a central passage that extends through the central tube from the proximal end to the distal end, wherein access to the central passage is permitted by each of the first central opening and the second central opening, wherein the inner side surface includes: a first segment extending from the proximal end, an intermediate shoulder segment extending from the first segment, and a second segment extending from the intermediate shoulder segment, wherein the first segment forms the central passage to include a first constant diameter, wherein the second segment forms the central passage to include a second constant diameter, wherein the second diameter is less than the first diameter, wherein the intermediate shoulder segment forms the central passage to include a non-constant diameter; and a seal disposed at least proximate a top surface of the distal end of the central tube. Br. 20, Claims Appendix ( emphasis added). The claims stand rejected under 35 U.S.C. § I03(a) as follows: 1. claims 1, 2, 7-10, 13, 14, 22, and 26 over Cooper (US Re. 30,779, issued Oct. 20, 1981) in view of Thomas (US 6,571,962 B2, issued June 3, 2003); 2. claims 3, 4, 15, and 16 over Cooper in view of Thomas and Rampen (US 2005/0133433 Al, published June 23, 2005); 3. claims 5 and 1 7 over Cooper in view of Thomas and J okschas (US 2003/0010707 Al, published Jan. 16, 2003); 4. claims 19, 20, 23, and 24 over Cooper in view of Thomas and Marshall (US 2008/0053886 Al, published Mar. 6, 2008); and 5. claims 21 and 25 over Cooper in view of Thomas and Fick (US 6,607,665 B2, issued Aug. 19, 2003). Final 2-10. 4 Appeal 2016-006537 Application 12/139,800 With respect to the first ground of rejection, Appellants present arguments in support of patentability of the following groups of claims: (1) claims 1 and 13; (2) claims 22 and 26; and (3) claim 8. See Br. 8-17. The remaining claims subject to this ground of rejection will stand or fall with claim 1 or claim 13. 37 C.F.R. § 4I.37(c)(iv) (2014). Appellants' traversal of grounds of rejection 2-5 relies on the same arguments presented in support of patentability of claims 1 and 13. See Br. 18. Claims 1 and 13 The Examiner finds Cooper discloses the invention as claimed in claims 1 and 13 with the exception of an outer side surface extending substantially perpendicularly with respect to an upper surface of the end cap for an entire length of the central tube from the proximal end to the distal end. See claim 1 (italicized language) supra p. 4; Br. 22 ( claim 13). In support of these findings, the Examiner provides Figure A, reproduced below, which is a portion of Cooper Figure 4 with annotations added by the Examiner. See Final 2. Fig. A 8.4' ' 85 86 89 rn.,....-.::a....~. / ) 80 . Ftrs.t Segrnerit Sewnd Segment Figure A is a longitudinal sectional view of upper end cap 80 and upper weir follower 82, attached thereto, in the filter assembly of Cooper Figure 4. See Cooper 4:36-38. Figure A includes the Examiner's annotations identifying the structure that corresponds to the claimed central 5 Appeal 2016-006537 Application 12/139,800 tube, first segment, intermediate shoulder segment, and second segment. See Final 2--4. The Examiner finds the outer surface of Cooper's central tube extends substantially perpendicularly with respect to the upper surface of end cap 80 along the first and second segments. Id. at 3. The Examiner finds, however, that the outer surface along the intermediate shoulder segment is not substantially perpendicular as claimed, but at an angle of approximately 45 degrees with respect to the upper surface of end cap 80. Id. The Examiner finds Thomas teaches a filter element that includes an end cap and integral central tube 66 having an inner side surface with first and second segments and an intermediate shoulder segment as claimed. Final 3 ( citing Figs. 9 and 11 ). The Examiner finds the entire length of central tube 66's outer surface is perpendicular to the end cap. Id. The Examiner relies on Thomas as evidence that filter elements having central tubes with varying thicknesses in different portions were known in the art at the time of the invention. Id. at 4. The Examiner finds that one of ordinary skill in the art would have modified Cooper's central tube by increasing its thickness along various portions of the outer surface in order to make those portions stronger than others. Id. The Examiner further finds making such modifications in a manner that resulted in a central tube having an outer surface that was perpendicular to the end cap would have been an obvious design choice, e.g., to provide an easy fit with other components of the filter element. Id. Appellants request reversal of the Examiner's rejection on the basis that the Examiner has not met the burden to show the prior art teaches or suggests every limitation of claims 1 and 13. Br. 10-11. Specifically, 6 Appeal 2016-006537 Application 12/139,800 Appellants contend the Examiner has not identified the disclosure in Cooper that corresponds to the claimed first, second, and intermediate shoulder segments with sufficient clarity. Id. at 11. We are not persuaded by this argument because Appellants have not explained, with any degree of specificity, why the Examiner's findings with respect to the three claimed segments is unclear from the Examiner's annotated Figure A. Nor have Appellants identified error in the Examiner's findings that Cooper discloses three segments as claimed, for the reasons explained in the Answer. See Ans. 2. Appellants argue Cooper explicitly teaches that end cap 80 and weir follower 82 must be identically-shaped in order to properly fit together. Br. 12-13. Appellants contend that if Cooper's end cap were modified as proposed by the Examiner, the end cap would no longer have the shape of the weir follower, rendering the end cap unsatisfactory for its intended purpose. Id. at 13-14. "It is well-established that a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements." In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (citations omitted). Appellants have not shown persuasively that the Examiner erred in finding one of ordinary skill would have possessed the requisite skills to modify Cooper's filter element, including the outer surface of the central tube and any parts that connect thereto, such as the weir follower. See Ans. 4 ("[O]ne skilled in the art would immediately recognize that if you change the shape of one element, an element that is supposed to be identical would also have to change, otherwise it would cease to identical."); KSRint'l Co. v. Teleflex Inc., 550 U.S. 398,421 (2007) ("A 7 Appeal 2016-006537 Application 12/139,800 person of ordinary skill is also a person of ordinary creativity, not an automaton."); In re Hanlon, 285 F.2d 829,831 (CCPA 1961) ("[A] mere change in shape or form is not patentable unless the changed element performs a new function"). Further, Appellants have not persuasively refuted the Examiner's finding that the ordinary artisan would have made such modification to achieve the benefits of increased strength and improved fit (see Final 4). More specifically, we are not persuaded by Appellants' arguments because they are not supported by evidence. See In re Geisler, 116 F.3d 1465, 1471 (Fed. Cir. 1997) (explaining that argument by counsel cannot take the place of evidence); In re Fox, 471 F.2d 1405, 1407 (CCPA 1973) (affirming the Board's decision and stating "[i]n this court appellant has not denied the existence of the facts on which the examiner rested his obviousness rejection nor the added facts of which the board took judicial notice"). We also agree with the Examiner's alternative finding that Cooper, alone, discloses a central tube having an outer side surface extending substantially perpendicularly with respect to an upper surface of the end cap for an entire length of the central tube from the proximal end to the distal end, as recited in claims 1 and 13. See Ans. 3--4. As noted by the Examiner, the term "substantially" is a broad term. Id. at 3. We find no indication in the specification that "substantially perpendicularly" requires an exact angle of 90 degrees between the central tube's outer side surface and upper surface of the end cap. Cooper does not specify the angle of the outer side surface of the segment identified by the Examiner as corresponding the claimed shoulder segment. Accordingly, it was reasonable for the Examiner to find 8 Appeal 2016-006537 Application 12/139,800 that Cooper's central tube has an outer surface that extends substantially perpendicularly as claimed. Claims 22 and 26 Claims 22 and 26 depend from claims 1 and 13, respectively, and recite "wherein the first segment forms a first constant thickness of the central tube, wherein the second segment forms a second constant thickness of the central tube, wherein the intermediate shoulder segment forms a non- constant thickness of the central tube, wherein the first thickness is less than the second thickness." Br. 24--25, Claims Appendix. Appellants contend the Examiner erred in finding that filter elements having central tubes with varying thicknesses in different portions were known in the art at the time of the invention. Br. 15-16. Appellants argue both Cooper and Thomas are silent with respect to varying thickness of the central tube. Id. at 16. Appellants further assert that "both ... Cooper and Thomas appear to include a constant thickness throughout the length of their respective alleged central tube structures." Id. Appellants' arguments are not persuasive because they are not consistent with Figures 9 and 11 of Thomas which illustrate differences in wall thickness along the length of Thomas' s central tube, including a thickness of a second segment that is greater than a thickness of the first segment. Ans. 5. Claim 8 Claim 8, by virtue of its dependency from claim 7, requires that the inner surfaces of the first and second segments of the central tube are substantially perpendicular with respect to the upper surface of the end cap, and that the inner surface of the shoulder segment is not substantially 9 Appeal 2016-006537 Application 12/139,800 perpendicular with respect to the upper surface of the end cap. Br. 21, Claims Appendix. Claim 8 further recites "wherein the inner shoulder surface portion is a standpipe actuator." Id. Appellants argue the Examiner has not identified sufficient evidence to support a finding that Cooper's shoulder segment is inherently a standpipe actuator. Br. 17. As noted by the Examiner, Appellants' argument is based on a misapprehension of the Examiner's rejection as based on inherency. Ans. 5. Rather, the Examiner's rejection is based on the correct interpretation of claim 8 as reciting a functional limitation. Id. "[P]atentability of apparatus claims must be shown in the structure claimed and not merely upon a use, function, or result thereof." In re Gardiner, 171 F.2d 313, 315-16 (CCPA 1948). Courts have interpreted functional language in an apparatus claim as requiring that the apparatus possess the capability of performing the recited function. See Intel Corp. v. US. Int'! Trade Comm 'n, 946 F.2d 821, 832 (Fed. Cir. 1991). As discussed above, the Examiner has shown persuasively that Cooper discloses a central tube having the same three segments recited in claim 1, from which claim 8 depends indirectly. Therefore, it was reasonable for the Examiner to find that the shoulder segment of Cooper's central tube ( as illustrated in Figure A, above) likewise would have been capable of functioning as a standpipe actuator. See Final 4. In sum, Appellants have failed to persuade us of reversible error in the Examiner's conclusion of obviousness as to claims 1, 8, 13, 22, and 26. Accordingly, we sustain the first ground of rejection as to claims 1, 2, 7-10, 13, 14, 22, and 26. We have considered Appellants' arguments in support of patentability of claims 1, 8, 13, 22, and 26 to the extent applicable to the 10 Appeal 2016-006537 Application 12/139,800 claims subject to grounds of rejection 2-5, but are not persuaded of reversible error on the part of the Examiner. Accordingly, we likewise sustain these grounds of rejection. The Examiner's decision to reject claims 1-5, 7-10, 13-17, and 19- 26 is affirmed. No time period for taking any subsequent action in connection with this appeal maybe extended under 37 C.F.R. §1.136(a)(l)(iv). AFFIRMED 11 Copy with citationCopy as parenthetical citation
