DECISION ON APPEAL 1 The two-month time period for filing an appeal or commencing a civil action, as recited in 37 C.F.R. § 1.304, begins to run from the decided date shown on this page of the decision. The time period does not run from the Mail Date (paper delivery) or Notification Date (electronic delivery). Appeal 2009-001562 Application 11/250,757 2 STATEMENT OF THE CASE Kenneth C. Kramer et al. (Appellants) seek our review under 35 U.S.C. § 134 of the Examiner’s decision rejecting claims 1-10. Claims 11-22 have been withdrawn. We have jurisdiction under 35 U.S.C. § 6(b) (2002). SUMMARY OF DECISION We AFFIRM. THE INVENTION The Appellants’ claimed invention is a coupler with expanded fittings that extend hydraulically or pneumatically in order to interconnect pipes and provide flow of any type of material in any type of piping system. Spec. 1:7-10. Claim 1, reproduced below, is representative of the subject matter on appeal. 1. A coupler with expanding fittings, comprising: an inner sleeve having an annular wall with an outwardly extending lip about an end of the inner sleeve, the wall of the inner sleeve having a passage defined therein having an inlet disposed on an exterior of the sleeve and having a discharge opening adjacent the lip; and an outer sleeve having a pipe flange at a first end and an inwardly extending lip at an opposing second end, the inwardly extending lip being slidably disposed upon the inner sleeve and encircling the inner sleeve, the discharge opening being disposed between the outwardly extending lip of the inner sleeve and the inwardly extending lip of the outer sleeve; Appeal 2009-001562 Application 11/250,757 3 wherein the outer sleeve travels along the outward surface of the outward extending lip of the inner sleeve, the range of travel of the outer sleeve being limited by the inwardly extending lip of the inner sleeve. THE EVIDENCE The Examiner relies upon the following evidence: Dale US 2,533,097 Dec. 5, 1950 Hunter US 3,735,772 May 29, 1973 Gorman, Jr. US 5,052,721 Oct. 1, 1991 Wallace US 6,073,906 Jun. 13, 2000 THE REJECTIONS The Appellants seek our review of the following rejections:2 1. The Examiner rejected claims 1, 3-8, and 10 under 35 U.S.C. § 103(a) as unpatentable over Gorman and Wallace. 2. The Examiner rejected claim 2 under 35 U.S.C. § 103(a) as unpatentable over Gorman, Wallace, and Dale. 3. The Examiner rejected claim 9 under 35 U.S.C. § 103(a) as unpatentable over Gorman, Wallace, and Hunter. ISSUES The Examiner found that Gorman discloses the Appellants’ device except that the wall of the inner sleeve does not have a passage defined therein. Ans. 3. The Examiner found that “Wallace teaches hydraulic 2 The provisional rejection of claims 1-5 under non-statutory obviousness- type double patenting was withdrawn by the Examiner due to the abandonment of Application No. 11/102,826. Ans. 2; App. Br. 5. Appeal 2009-001562 Application 11/250,757 4 pressure to adjust the positioning of an outer sleeve with at least one passageway being provided through a sidewall of an inner sleeve.” Ans. 3. The Examiner concluded that it would have been obvious to a person of ordinary skill in the art at the time of Appellants’ claimed invention to add the hydraulic passageway of Wallace to the device of Gorman, “in order to provide a hydraulic means for adjusting the position of the outer sleeve.” Ans. 3-4. The Appellants contend that there is no reason to modify Gorman with Wallace as found by the Examiner because Wallace is not analogous art to Gorman, and Gorman teaches away from the combination proposed by the Examiner. App. Br. 10. The first issue before us is: Have the Appellants demonstrated that the Examiner erred in the relying on the combination of Gorman and Wallace in the rejection of claims 1, 3-8, and 10 either because Wallace is not analogous art to Gorman, or because Gorman teaches away from the combination proposed by the Examiner? The Examiner found that the combination of Gorman as modified by Wallace in the first rejection meets the limitations of claim 2 except that this combination does not disclose a spring. Ans. 4-5. The Examiner found that Dale discloses a spring placed “between an outwardly extending lip of an inner sleeve and a pipe flange of an outer sleeve.” Ans. 5. The Examiner concluded that it would have been obvious to a person of ordinary skill in the art to utilize a spring as taught by Dale to provide a force to restore “the joint to a normal condition” and to “achieve a desired positioning of movable elements.” Ans. 5. Appeal 2009-001562 Application 11/250,757 5 The Appellants contend that Dale does not disclose a spring located as claimed. App. Br. 11. The Appellants also contend there is no rational basis to combine Dale with the Gorman and Wallace combination proposed by the Examiner because Gorman and Dale are not analogous art since a person of ordinary skill in the art looking to modify the water service coupling of Gorman would not look to the field of expansion joints (such as Dale). App. Br. 11-13. The second issue before us is: Have the Appellants demonstrated that the Examiner erred in relying on the combination of Gorman, Wallace, and Dale in the rejection of claim 2 either because there is no rational basis to combine the teachings of Dale to the modified Gorman device in the manner claimed or because Gorman is not analogous art to Dale? FINDINGS OF FACT We find that the following enumerated facts are supported by at least a preponderance of the evidence. Ethicon, Inc. v. Quigg, 849 F.2d 1422, 1427 (Fed. Cir. 1988) (explaining the general evidentiary standard for proceedings before the Office). 1. The Appellants’ Specification describes the claimed invention as a coupler that interconnects pipes and provides flow of “any type of material” in “any type of piping system.” Spec. 1:10-11. The Appellants’ Specification describes the claimed invention as related to the art of pipe fittings, which is “[t]he work of installing and maintaining pipe systems.” Spec. 1:7; 3:1-2. The Appellants’ Specification describes that “[v]alves are often used in pipe systems.” Spec. 3:2. The Appellants’ Specification Appeal 2009-001562 Application 11/250,757 6 describes pipe fitters facing difficulties removing and replacing “pipe sections and/or valves.” Spec. 3:13-15; see also Spec. 12:15-16 (referring to piping systems frequently being cut to add “pipes and/or install a valve”). The Appellants’ Specification describes the claimed invention as “designed to eliminate the cost and labor of interconnecting pipes and/or valves in any type of piping system.” Spec. 7:5-6. 2. The Appellants’ Specification lists several “improvements relating to piping systems,” in the prior art as related to the problem faced by the Appellants, including several references related to valves. See, e.g., Spec., 4:9; 4:17- 5:1; 5:8-9, 12; 6:6. 3. The Appellants’ Specification describes that the claimed device is designed to overcome problems in the prior art by making removal and replacement of a pipe fitting easier. Spec. 2:9 - 4:3. 4. Gorman discloses a water meter service coupling with an expandable piston to facilitate removal and/or replacement by allowing for expansion of the water service line upon disconnection of the water meter. Gorman, col. 1, ll. 10-17. 5. Gorman discloses that the invention overcomes service line expansion and other issues associated with underground installation that make removal and replacement of the water meter coupling difficult. Gorman, col. 1, l. 48 to col. 2, l. 3. 6. Gorman does not discuss, discourage, or discredit the notion of using hydraulic or pneumatic power to facilitate movement of the expandable piston. Gorman, passim. Appeal 2009-001562 Application 11/250,757 7 7. Wallace discloses a flow control device for a water well. Wallace, col. 1, ll. 13-14. Wallace’s device is a valve 1 comprised of a pipe section (with upper end 20a and lower end 20b) with a throttle portion 6 configured as a sleeve around the pipe section. Wallace, col. 5, ll. 4-10; Figs. 1A; see also Wallace, col. 2, ll. 54-55 (referring to the device as concentric cylinders or tubular members). 8. Throttle portion 6 is hydraulically operated to open and close “D” ports 8. Wallace, col. 5, ll. 9-12, 42-44. When the pump is operating, valve 1 is in the closed position 7 (i.e. throttle portion 6 closing “D” orifices 8). Wallace, col. 5, ll. 14-15; Fig. 1A. During recharge operations, throttle portion 6 moves so that it opens and closes “D” orifices 8 to control water flow through the orifices. Wallace, col. 5, ll. 9-12. 9. Wallace discloses objectives of the device are to permit minor adjustments to flow from the well head, and to provide simple, durable, and cost effective down-hole flow control in wells that eliminates or reduces: air-fouling, air entrainment, and air binding. Wallace, col. 3, ll. 24-47. 10. Dale discloses a pipe coupling that serves as a wide take-up union, an expansion joint, or both. Dale, col. 1, ll. 1-5. Objects of the invention are to interconnect telescopically movable pipe sections for movement of the sections during assembly, and for movement of the pipes after assembly in response to expansion of the pipe lengths. Dale, col. 1, ll. 6-18. Appeal 2009-001562 Application 11/250,757 8 11. Dale discloses the pipe joint 10 includes an inner and an outer pipe section 11, 12. Dale, col. 1, ll. 29-30. Pipe section 12 has a cylindrical end portion 13 with an outer surface 15, that fits in telescopic relation within the bore 14 of pipe section 11, and is sealed by O-ring packing 16. Dale, col. 1, ll. 32-44. Inner pipe section 12 carries a sleeve nut 18 that includes threads that join sleeve nut 18 to outer pipe section 11, and threads on shoulder 20 of the sleeve nut 18 so that it turns tightly against the flange 21 of inner pipe section 12. Dale, col. 1, ll. 51-54; Figs. 1, 2. When assembled, an annular space 24 is formed with the inner circumferential boundary defined by inner pipe section 12, the outer circumferential boundary defined by sleeve nut 18, and the ends of the space defined by the end of outer pipe section 11 and the flange 21 of inner pipe section 12. Dale, col. 2, ll. 31-32; Figs. 1, 2. Dale discloses a coil spring 25 may be inserted in annular space 24 to bias the joint 10 to the expanded position. Dale, col. 2, ll. 28-34, Figs. 1, 2. 12. The Appellants present no evidence that the combination of Gorman and Wallace found by the Examiner is beyond the skill of a person of ordinary skill in the art. App. Br., passim. PRINCIPLES OF LAW Whether a reference teaches away from a claimed invention is a question of fact. In re Harris, 409 F.3d 1339, 1341 (Fed. Cir. 2005). “A reference may be said to teach away when a person of ordinary skill, upon reading the reference would be led in a direction divergent from the path that Appeal 2009-001562 Application 11/250,757 9 was taken by the applicant.” In re Haruna, 249 F.3d 1327, 1335 (Fed. Cir. 2001). “[W]hen the prior art teaches away from combining certain known elements, discovery of a successful means of combining them is more likely to be nonobvious.” KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007) (citing United States v. Adams, 383 U.S. 39, 51-52 (1966)). “The analogous-art test requires that the Board show that a reference is either in the field of the applicant's endeavor or is reasonably pertinent to the problem with which the inventor was concerned in order to rely on that reference as a basis for rejection. In re Kahn, 441 F.3d 977, 986-87 (Fed. Cir. 2006) (citing In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992). The “field of endeavor” test asks if the structure and function of the prior art is such that it would be considered by a person of ordinary skill in the art because of the similarity to the structure and function of the claimed invention as disclosed in the application. In re Bigio, 381 F.3d 1320, 1325-27 (Fed. Cir. 2004). “‘A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor's endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an inventor's attention in considering his problem.’ In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992). “In other words, ‘familiar items may have obvious uses beyond their primary purposes.’” In re ICON Health and Fitness, Inc, 496 F.3d 1375, 1380-1 (Fed. Cir. 2007) (quoting KSR Int’l Co., 550 U.S. at 402). “Section 103 forbids issuance of a patent when ‘the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said Appeal 2009-001562 Application 11/250,757 10 subject matter pertains.’” KSR Int'l Co., 550 U.S. at 406. The question of obviousness is resolved on the basis of underlying factual determinations including (1) the scope and content of the prior art, (2) any differences between the claimed subject matter and the prior art, (3) the level of skill in the art, and (4) where in evidence, so-called secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17-18 (1966). See also KSR Int'l Co., 550 U.S. at 407 (“While the sequence of these questions might be reordered in any particular case, the [Graham] factors continue to define the inquiry that controls.”) ANALYSIS Rejection of claims 1, 3-8 and 10 and under 35 U.S.C. § 103(a) as unpatentable over Gorman and Wallace3 The Appellants argue claims 1, 3-8, and 10 as a group. App. Br. 6-10. As such, we select claim 1 as the representative claim, and claims 3-8 and 10 stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(vii) (2008). The Appellants make several arguments why there is no rational basis to combine Gorman with Wallace as proposed by the Examiner. The Appellants argue Gorman and Wallace are not analogous art to each other because Wallace is not in the same field of endeavor as Gorman, and because Wallace is not pertinent to the problem confronting Gorman. App. Br. 10. The correct focus of the analogous art test is not whether the prior art references are analogous to each other, but rather the correct focus is whether the references are analogous art to the claimed subject matter. In 3 While the Appellants group claim 9 with this ground of rejection, claim 9 is subject to a different ground of rejection and is, therefore, treated separately in the analysis of the third rejection, infra. See App. Br. 6. Appeal 2009-001562 Application 11/250,757 11 re Kahn, 441 F.3d 977, 986-87 (Fed. Cir. 2006). We make two conclusions regarding Appellants’ assertion. One, by asserting Wallace is not analogous to Gorman, Appellants have not asserted that Gorman is not analogous art to the subject matter of claim 1. Two, Appellants have the burden to show error in the Examiner’s rejection, and have failed to prove error by asserting that Wallace is not analogous art to Gorman. Because both Gorman and the subject matter of claim 1 relate to pipe fittings, to the extent that the Appellants’ argument that Wallace is not analogous art to Gorman can be interpreted as asserting that Wallace is not analogous art to the subject matter of claim 1, we analyze that assertion. To determine if Wallace and the subject matter of claim 1 are in the same field of endeavor, we look to the structure and function of each. The structure of claim 1 is a coupler with an outer sleeve that travels along the outer surface of an inner sleeve. The Appellants’ Specification describes the structure as a coupler that interconnects pipes and provides flow (Fact 1). The Appellants’ Specification broadly describes the function of the device as providing flow of “any” type of material in “any” type of piping system (Fact 1). Wallace discloses a device with a structure that is an inner sleeve within an outer sleeve (Fact 7). Wallace discloses that during pumping, the valve is in the closed position, simply providing flow, and during recharge operations, the valve adjusts to control water flow through the “D” orifices (Fact 8). In this way, Wallace’s device serves as both an interconnecting pipe and as a valve. Wallace’s device and Appellants’ claimed device are structurally similar in that both are pipe fittings comprised of pipe sections with an inner and an outer sleeve. Regarding function, Wallace’s device, when in the Appeal 2009-001562 Application 11/250,757 12 closed position, provides flow, and the Appellants’ device also provides flow. Beyond these similarities of structure and function, the Appellants’ Specification describes the field of the invention as relating to pipe fittings, “the work of installing and maintaining pipe systems,” and further describes that valves are often used in pipe systems (Fact 1). By this description, Wallace’s device, like Appellants’, is a pipe fitting. We find that Wallace and the subject matter of claim 1 are in the same field of endeavor, so that Wallace is analogous art to the Appellants’ device. The Appellants also argue that Gorman uses a piston for movement and would have no reason to utilize hydraulic pressure, and therefore no reason to incorporate the internal passage taught by Wallace. App. Br. 8. Similarly, the Appellants assert that there is no motivation or common sense rationale to modify Gorman in view of its goal of providing a coupling with retracting capabilities to facilitate removal and replacement of a water meter. App. Br. 9. We disagree. The Appellants’ arguments fail to address the reason to modify Gorman provided by the Examiner, namely, “to provide hydraulic means for adjusting the position of the outer sleeve.” Ans. 3-4. This rationale is sound, given that Gorman’s coupling is intended for underground installation, exposing the device to debris and corrosion so that hydraulic assistance for retracting the coupling would serve Gorman’s intended purpose of easy removal and replacement (Fact 5). The Appellants’ conclusory statement, unsupported by any explanation why the Examiner’s reason to modify is incorrect, is unconvincing. The Appellants also assert that “[i]t is unclear how Wallace’s double axial passageways will conform to Gorman’s sealed voids,” followed by an Appeal 2009-001562 Application 11/250,757 13 argument that Gorman teaches away from the combination proposed by the Examiner. App. Br. 10. The Appellants provide no evidence that the combination proposed by the Examiner is beyond the skill of a person of ordinary skill in the art (Fact 12). Further, the Appellants’ conclusory assertion, without more, fails to convince us that a person of ordinary skill in the art would be unable to solve the issue raised by the Appellants. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007) (It is proper to "take account of the inferences and creative steps that a person of ordinary skill in the art would employ."). See also id. at 421 ("A person of ordinary skill is also a person of ordinary creativity, not an automaton."). Regarding the Appellants’ teaching away argument, Gorman is silent concerning the use of hydraulic power for retracting the expandable piston (Fact 6). Silence alone would not lead a person of ordinary skill in the art in a direction divergent from that chosen by the Appellants. In re Haruna, 249 F.3d 1327, 1335 (Fed. Cir. 2001). The Appellants have failed to demonstrate error by the Examiner in the decision to reject claim 1 as unpatentable over Gorman and Wallace. Claims 3-8 and 10 fall with claim 1. Rejection of claim 2 under 35 U.S.C. § 103(a) as unpatentable over Gorman, Wallace, and Dale Claim 2 includes the limitation of a “compression spring disposed between the outwardly extending lip of the inner sleeve and the pipe flange.” Dale discloses a pipe joint comprised of inner and outer pipe sections, and a sleeve nut on the inner pipe section that slides onto the outer pipe section (Fact 11). Dale’s device also includes a spring that biases the joint to Appeal 2009-001562 Application 11/250,757 14 the expanded position located in the annular space formed with the inner circumferential boundary defined by the inner pipe section, the outer circumferential boundary defined by the sleeve nut, and the ends of the space defined by the end of the outer pipe section and the flange of inner pipe section (Fact 11). The Appellants correctly assert that Dale’s spring is not located as claimed. App. Br. 11. However, the requirement is not that Dale’s spring must be capable of being bodily incorporated into the combined device of Gorman and Wallace as found by the Examiner. In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference...Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art”). Dale’s spring, like that of claim 2, serves to bias the joint to the expanded position by providing opposing forces on the inner and outer sleeve (Fact 11). We find that a person of ordinary skill in the art, knowing this teaching from Dale, would recognize the technique may be used to improve the combined Gorman-Wallace device in a similar way. KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007) (“if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill”). The Appellants contend Dale and Gorman are not analogous art to each other because “Dale is an expansion joint and Gorman is a water service coupling.” App. Br. 11-13. Here, as in claim 1, supra, the Appellants have not properly asserted an analogous art argument, and have Appeal 2009-001562 Application 11/250,757 15 failed to demonstrate error by the Examiner on that basis. To the extent that the argument can be construed as asserting both Dale and Gorman are not analogous to Appellants’ claimed device, we analyze that contention. Dale’s structure of inner and outer pipe sections (Fact 11) is similar to Appellants’ structure of a coupler with an outer sleeve that travels along the outer surface of an inner sleeve. Dale’s function of providing a movable pipe for movement of the sections during assembly (Fact 10) is similar to the Appellants’ function of providing a pipe fitting that is easy to remove and replace (Fact 3). Further, as we found in the analysis of claim 1, supra, Appellants’ Specification describes the field of the claimed invention as pipe fittings, which includes interconnecting pipes and valves (Fact 1). By this definition, Dale’s device is a pipe fitting. We find that Dale and the subject matter of claim 2 are in the same field of endeavor, and are therefore analogous art. Quite similarly, Gorman discloses a coupling (pipe fitting) with an expandable piston to facilitate removal and replacement, with similar structure and function to the Appellants’ device (Facts 4, 5). Gorman is also analogous art to the Appellants’ device. Because Dale and Gorman are analogous art to the Appellants’ clamed device, the Appellants have failed to demonstrate that the Examiner erred in the decision to reject claim 2. Rejection of claim 9 under 35 U.S.C. § 103(a) as unpatentable over Gorman, Wallace, and Hunter The Appellants list claim 9 with the claims of the first rejection over Gorman and Wallace under 35 U.S.C. § 103(a), and assert that Hunter does Appeal 2009-001562 Application 11/250,757 16 not cure the deficiencies of the Gorman-Wallace combination suggested by the Examiner. App. Br. 6. Because we concluded in the analysis of claim 1, supra, that the Appellants have not demonstrated error by the Examiner in the decision to reject claim 1 as obvious over Gorman and Wallace, there is no deficiency for Hunter to cure. The Appellants have failed to demonstrate error by the Examiner in the rejection of claim 9. CONCLUSION The Appellants have failed to demonstrate that the Examiner erred in the rejection of claims 1 and 3-10 because Wallace is analogous art to the Appellants’ device, and Gorman does not teach away from the combination proposed by the Examiner The Appellants have failed to demonstrate that the Examiner erred in the rejection of claim 2 because a person of ordinary skill in the art, knowing Dale’s disclosure of a spring, would recognize how to improve the Gorman- Wallace device in a similar way, and because both Dale and Gorman are analogous art to the Appellants’ clamed device. DECISION We affirm the Examiner's rejection of claims 1-10. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R. § 1.136(a)(1)(iv) (2007). AFFIRMED Appeal 2009-001562 Application 11/250,757 17 Vsh LITMAN LAW OFFICES, LTD.
