Also, claim 3 stands rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement, and claims 1—5 stand provisionally rejected on the ground of nonstatutory obviousness-type double patenting as follows: claims 1, 2, 4 and 5 over claims 1—5 of copending Application No. 12/950,403, and claim 3 over claims 1 and 3 of copending Application No. 12/950,403 in view of Marshall. OPINION We affirm the rejections. Rejections under 35 U.S.C. § 103 The Appellants argue only the sole independent claim, i.e., claim 1 (Br. 4—11). We therefore limit our discussion to that claim. See 37 C.F.R. § 41.37(c)(l)(iv) (2012). Rejection over Oku in view of Deal 3 Appeal 2014-004044 Application 12/950,327 Oku discloses “a method and apparatus for the lamination of band-shaped uncured rubber members in the building of a pneumatic tire” (13) and teaches that “[i]n the production of the composite comprised of various rubbers, a step of laying various uncured rubber members is required prior to the curing of the composite” (1 5). Oku’s method includes feeding a first rubber material (A) through a feeder (5) to an extruder (2), extruding the first rubber material (A) through the extruder (2) and helically winding the extruded first rubber material (A) onto a rotating support (1) to form a first rubber layer, and continuously extruding the first rubber material (A) while feeding a second rubber material (B) through the feeder (5) to the extruder (2) so as to stepwise or gradually increase a blending ratio of the second rubber material (B) to the first rubber material (A) while holding the same extrusion sectional shape and helical winding on the first rubber layer to form a second mbber layer which overlaps at least a part of the first rubber layer 15—17, 47, 53; Fig. 1). A feed control (4) individually adjusts the feeding quantities of the rubber materials (A, B) (| 45; Fig. 1). Deal continuously mixes two base elastomers fed from separate hoppers (5) in a controlled ratio through separate twisted knives (53) which shred and plasticize the elastomers and transfer them to separate gear pumps (55) which pump the elastomers through separate pipelines (56) to a single line (57) through which the elastomers go to a mixing chamber (11) comprising an elongated helical rotor (2) within a cylindrical stator (1) (col. 1,11. 8-9; col. 6,11. 7-9, 17-21; col.7,11. 7-38; col. 10,11. 18-22, 25- 28, 59-62; Figs. 1,3). The Appellants assert that Oku does not disclose gear pumps (Br. 5— 6). 4 Appeal 2014-004044 Application 12/950,327 That argument is deficient in that the Appellants are attacking Oku individually when the rejection is based on a combination of references. See In re Keller, 642 F.2d 413, 426 (CCPA 1981); In re Young, 403 F.2d 754, 757—58 (CCPA 1968). The Examiner relies upon Deal for a suggestion to use gear pumps to feed Oku’s elastomers (A), (B) to the extruder (2) (Final Act. 5). The Appellants argue that “[a] person skilled in the art would understand that an extruder utilizes pressure in order to force rubber through a die. Deal’s knife is concerned with shredding, and thus would not quality as the claimed extruder because of the lack of pressure and die” (Br. 6). ‘“[Djuring examination proceedings, claims are given their broadest reasonable interpretation consistent with the specification.’” In re Translogic Tech. Inc., 504 F.3d 1249, 1256 (Fed. Cir. 2007) (quoting In re Hyatt, 211 F.3d 1367, 1372 (Fed. Cir. 2000)). The Appellants’ Specification does not indicate that the Appellants’ claim term “extruder” has any meaning other than its ordinary meaning, i.e., an apparatus for “[fjorcing a substance through an aperture.”2 Deal’s twisted knifes (53) not only shred, but due to their helix’s progressively decreasing pitch, also plasticize the elastomer and force it into a gear pump (55) (col. 4,1. 62 — col.5,1. 6; col. 7, 11. 26—34; Fig. 1). Thus, Deal’s knives are extruders according to the broadest reasonable interpretation of that term consistent with the Appellants’ Specification. The Appellants assert that replacing Oku’s feed controller (4) with Deal’s gear pumps (55) would destroy Oku’s feed control (Br. 7). 2 Hackh’s Chemical Dictionary 259 (McGraw-Hill 1977). 5 Appeal 2014-004044 Application 12/950,327 The rejection is not based upon replacing Oku’s feed controller (4) but, rather, is based upon using Deal’s gear pumps (55) to feed Oku’s controlled elastomer flows to the extruder (2) (Final Act. 6). The Appellants assert that if all of Deal’s gear pumps are mounted on the same shaft, it would not be possible to vary the speed of one pump relative to another (Br. 7). Deal’s gear pumps (55) which feed the elastomers to the mixing chamber (11) are on separate shafts (Fig. 3) and the elastomers are fed to the mixing chamber (11) in controlled relative dosages (col. 6,11. 16—21; col. 10, 11. 18-22, 25-28). The Appellants assert that neither Deal nor Oku discloses a main gear pump (Br. 7). Deal’s mixing chamber (11; Fig. 1) corresponds to the Appellants’ main extruder, and whichever of Deal’s gear pumps (55) pumps the most elastomer can be considered a main gear pump, the other being considered a second gear pump. Rejections over Ohashi or Katakabe, in view of Skibba and Uphus Ohashi flflf 11, 23—25; Fig. 1) provides essentially the same relevant disclosure as that set forth above regarding Oku. Katakabe discloses an apparatus comprising “mixer-extruder means for mixing separately produced rubber compositions having a relatively fast and relatively low vulcanization rate respectively at a variable mixing ratio and extruding the constituent rubbers thereby obtained having different vulcanization rates” (col. 2,11. 34—39). 6 Appeal 2014-004044 Application 12/950,327 Skibba discloses “an extrusion conveying apparatus [10] having an extruder [12] that operates as a mixing device and that can be laterally supplied with components that are to be mixed, in particular components of a rubber mixture or thermoplastic elastomer (TPE), whereby a volumetrically acting conveyor, in particular a gear pump [14], is connected to an output side of the extruder [12],[3] and whereby the components that are supplied pass through volumetric subsidiary conveyors [28, 30,32], which in particular are also embodied as gear pumps and the rotation speed or feed rate of which is adjustable independently of the feed rate of the volumetrically acting conveyor [14]” (| 2; Fig.). Uphus continuously produces rubber mixtures by “plasticizing rubber in a short-screw extruder [5] to prepare plasticized rubber, and feeding plasticized rubber through intervention of a gear pump [3] to a twin-screw extruder [2] at a predetermined temperature and predetermined volume flow. Suitably, the gear pump [3] and the short-screw extruder [5] can be separately powered and controlled by a suitable drive system” (| 14; Fig. 1). The Appellants assert that Ohashi and Katakabe fail to disclose a main gear pump or a second gear pump (Br. 8, 10). The Appellants improperly are attacking Ohashi and Katakabe individually when the rejection is based on a combination of references. See Keller, 642 F.2d at 426; Young, 403 F.2d at 757—58. The Examiner relies upon Skibba and Uphus for a suggestion to use gear pumps in Ohashi’s and Katakabe’s apparatus (Final Act. 8—9, 13—14). 3 “The drive mechanism of the gear pump 14 is independent of the drive mechanism of the extruder 12” (| 28). 7 Appeal 2014-004044 Application 12/950,327 The Appellants argue that because Ohashi and Katakabe already have a supply device that individually adjusts the relative amounts of elastomers, one of ordinary skill in the art would have had no reason to modify their apparatus (Br. 9, 11). Setting forth a prima facie case of obviousness requires establishing that the applied prior art would have provided one of ordinary skill in the art with an apparent reason to modify the prior art to arrive at the claimed invention. See KSRInt’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Skibba’s disclosure that use of an extruder (12) output gear pump (14) having a drive mechanism independent of that of the extruder (12) and use of subsidiary gear pumps having feed rates that are independent of the feed rate to the extruder (12)’s output gear pump (14) enable good mixing of components having poor mixing behavior flflf 2, 9, 28) would have provided one of ordinary skill in the art with an apparent reason to use those gear pumps in Ohashi’s and Katakabe’s methods to obtain that benefit. Uphus’ disclosure that use of a short-screw extruder (5) to feed plasticized rubber to a separately-operated gear pump (3) which pumps the elastomer into a twin-screw extruder (2) provides the benefit of higher throughput at the same short-screw extruder (5) speed or the same throughput at a reduced short-screw extruder (5) speed (120) would have provided one of ordinary skill in the art with an apparent reason to use Uphus’ short-screw extruders (5) as Skibba’s subsidiary conveyors (28, 30, 32) to obtain that benefit.4 4 Thus, the Appellants’ assertion that “none of the cited references alone or in combination teach the step of adjusting the speed of the main gear pump 8 Appeal 2014-004044 Application 12/950,327 For the above reasons we are not persuaded of reversible error in the rejections under 35 U.S.C. § 103. Rejection under 35 U.S.C. § 112, first paragraph, written description requirement and provisional obviousness-type double patenting rejections The Appellants do not challenge the rejection under 35 U.S.C. § 112, first paragraph written description requirement or the provisional obviousness-type double patenting rejections. Accordingly, we summarily affirm those rejections. DECISION/ORDER The rejections under 35 U.S.C. § 103 of claims 1, 2 and 5 over Oku in view of Deal, claim 3 over Oku in view of Deal and Koumo, claim 4 over Oku in view of Deal and Kudo, claims 1, 2 and 4 over Ohashi in view of Skibba and Uphus, claim 3 over Ohashi in view of Skibba, Uphus and Marshall, claim 3 over Ohashi in view of Skibba, Uphus and Galimberti, claim 5 over Ohashi in view of Skibba, Uphus and Mancini, claims 1 and 2 over Katakabe in view of Skibba and Uphus, claim 3 over Katakabe in view of Skibba, Uphus and Marshall, claim 3 over Katakabe in view of Skibba, Uphus and Galimberti and claims 4 and 5 over Katakabe in view of Skibba, Uphus and Kozima, the rejection of claim 3 under 35 U.S.C. § 112, first paragraph, written description requirement, and the provisional rejections on the ground of nonstatutory obviousness-type double patenting of claims 1, 2, 4 and 5 over claims 1—5 of copending Application No. 12/950,403, and and the second gear pump to obtain a second blend ratio of said first compound to said second compound” (Br. 9, 11) is not well taken. 9 Appeal 2014-004044 Application 12/950,327 claim 3 over claims 1 and 3 of copending Application No. 12/950,403 in view of Marshall are affirmed. It is ordered that the Examiner’s decision is 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).
