Opinion Dissenting-in-Part by Administrative Patent Judge ADAMS. SA WERT, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) from the rejection of claims 18, 20-23, 25-30, and 32-35. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm. 1 Appellants identify Colgate-Palmolive Company, GABA International Holding AG, Grabelsmaltweg, 4106 Therwil, CH, as the real party in interest. Br. 2. Appeal2017-003667 Application 14/461,798 STATEMENT OF THE CASE Claims 18, 20-23, 25-30, and 32-35 are on appeal. Claims 22, 23, 26-28, 30, and 32-35 stand rejected as unpatentable under 35 U.S.C. § 112, second paragraph, for indefiniteness. Ans. 2. Claims 18, 20-23, 25-30, and 32-35 stand rejected under 35 U.S.C. § 103(a) for obviousness over Gross2 in view oflto. 3 Id. at 3-5. We choose independent claim 18 as representative. See 37 C.F.R. § 4I.37(c)(l)(iv). Claim 18 provides: 18. A head for a toothbrush, the head having a longitudinal axis and comprising: a bristle surface with tufts of bristles set therein; wherein the tufts of bristles comprise a first tuft that is vertical on the bristle surface and a second tuft that is slanted on the bristle surface; and wherein the first tuft consists of pointed bristles and the second tuft consists of cylindrical bristles. Br. 13. BACKGROUND Appellants' claimed invention is directed to a toothbrush head having both slanted tufts of bristles and upright ( or vertical) tufts of bristles, wherein the slanted tufts are cylindrical and the upright tufts are pointed. Spec. ,r 6. The Specification states that toothbrushes having mixed slanted and upright tufts were known. Id. ,r 3. "Recently," the Specification continues, "tooth brushes with so-called 'pointed' bristles have also become known .... " Id. ,r 4. The Specification explains that "[p]ointed bristles are 2 Peter Gross and Alfred Jurt, WO 00/25631 (May 11, 2000) ("Gross"). 3 Ryu Ito et al., U.S. Patent No. 5,533,227 (July 9, 1996) ("Ito"). 2 Appeal2017-003667 Application 14/461,798 more flexible than traditional bristles and therefore allow for a more gentle cleaning of the tooth surfaces with less risk of injury." Id. The Specification states that "the present invention [is] a further improvement of the brush heads for tooth brushes." Id. ,r 5. Figure 1, reproduced below, shows slanted and vertical tufts according to the claimed invention. The vertical tufts have pointed bristles whereas the slanted tufts have cylindrical bristles. l-! 'dx' L-___________ __ Fig. 1 shows slanted/cylindrical and vertical/pointed bristle tufts according to the claimed invention. Id. ,r 9. DISCUSSION Indefiniteness The Examiner rejected claims 22, 23, 26-28, 30, and 32-35 under 35 U.S.C. § 112, second paragraph, for failing to particularly point out and distinctly claim the subject matter applicant regards as the invention. "[T]he Office establishes a prima facie case of indefiniteness with a rejection explaining how the metes and bounds of a pending claim are not clear because the claim contains words or phrases whose meaning is unclear." Ex parte McAward, Appeal 2015-006416, 2017 WL 3669566, at *2 (PTAB Aug. 25, 2017) (precedential); see also MPEP § 2173.02; In re Packard, 751 3 Appeal2017-003667 Application 14/461,798 F.3d 1307, 1314 (Fed. Cir. 2014) ("[W]e affirm the Board's findings as to indefiniteness under the MPEP standard properly applied by the USPTO .... "). The Examiner states that the claim limitation "'wherein the second tuft is slanted forward ... the third tuft is slanted backward"' is indefinite because "'forward' and 'backward' are relative directions and the claim fails to define these directions with respect to the device." Ans. 2. As Appellants point out, however, the Specification defines both terms: [T]he term "slanting backward" means in the context of the present application that a backward slanting tuft is tilted toward the handle part by the acute angle, looking in the lengthwise direction of the bristle carrier, and the term "slanting forward" means in the context of the present application that a forward slanting tuft is tilted away from the handle part by the acute angle, looking in the lengthwise direction of the bristle carrier. Br. 5 ( quoting Spec. ,r 15). We agree with Appellants that there is no legal requirement that the claim itself define "slanted forward" and "slanted backward" when the Specification expressly does so. See id. at 5---6. We therefore reverse this rejection. Obviousness The Examiner rejected claims 18, 20-23, 25-30, and 32-35 under 35 U.S.C. § 103(a) for obviousness over Gross in view of Ito. Ans. 3-5. A claimed invention is unpatentable if the differences between it 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." 35 U.S.C. § 103(a) (pre-AIA). To assess whether the subject matter would have been obvious, the Board follows guidance in Graham v. John Deere Co., 383 U.S. 1 (1966) and KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398 4 Appeal2017-003667 Application 14/461,798 (2007). Under that guidance, the "combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results." KSR, 550 U.S. at 416. After considering the entirety of the evidence and Appellants' arguments, we conclude that the weight of the evidence favors the Examiner's conclusion of obviousness. Gross teaches a toothbrush head that comprises a plurality of bristle tufts. Gross, Abstract. Gross' s toothbrush head is reproduced below in Figure 1: 4 6 5 5 4 3 FIG. 1 shows an embodiment of Gross's toothbrush head. Id. The plurality of bristle tufts are anchored in the bristle support 3 of the toothbrush head 2, forming bristle bundles 4, 5, and 6. Id. The bristle bundles are arranged beside each other into a plurality of transverse rows. Id. Gross teaches that one or more of those bristle bundles are perpendicular to the bristle support ( 4 ), whereas other bristle bundles are inclined to the bristle support (5 and 6). Id. As to the latter bristle bundles, they are either "inclined towards the front" or "towards the rear" so that the bristle bundles "cross each other and define an X-shaped structure for each pair." Id. 5 Appeal2017-003667 Application 14/461,798 Ito discloses a toothbrush comprising bristles having pointed, tapered tips. Ito (Abstract). The tapered, pointed tips are illustrated in Figure 4, below: 14 16- 20·· '/' 12 : ~ ' ,: ~.:, i i ••••••••••••••••••n~n~-------~~~-~---·-··· Figure 4 is a side view of Ito's disclosed toothbrush. Ito 3 :29-- 30. Ito states that the tapered, pointed tips allow the bristles to "enter or reach areas such as recesses between teeth, boundaries between teeth and gingivae, and the like to effectively remove dental plaque ... and exhibit a soft feeling sufficient to prevent damage to gingivae." Id. (Abstract). The Examiner interpreted the bristle tufts of Gross as cylindrical in shape because of their rounded ends as shown in Figures 1 and 2. Ans. 3. The Examiner also found that Ito's tapered, pointed bristles "permit the bristle tips of the vertical tufts to better reach areas between teeth thereby providing more thorough cleaning action and helping to prevent periodontal disease." Id. at 3 ( citing Ito, 13: 1-19). The Examiner therefore reasoned that: it would have been obvious to one possessing ordinary skill in the art at the time of the invention to modify the device of Gross by providing the vertically projecting tufts consisting of tapered bristles in view of Ito in order to better clean different areas of the mouth during use. The proposed modification results in all of the slanted bristle tufts consisting of cylindrical bristles ( as taught by the base reference Gross) and all of the vertical tufts 6 Appeal2017-003667 Application 14/461,798 consisting of pointed bristles with all of the tufts having the same height (as taught by the base reference Gross). Id. 3--4. On appeal, the Board "reviews the obviousness rejection for error based upon the issues identified by appellant, and in light of the arguments and evidence produced thereon." Ex parte Frye, 94 USPQ2d 1072, 1075-76 (BPAI 2010) (Precedential). We address each issue raised by Appellants below. Appellants first argue that "Ito teaches away from a brush having a combination of both pointed bristles and cylindrical bristles." Br. 11. In particular, Appellants point out that Ito fails to disclose cylindrical bristles, and furthermore "discusses the problems with standard pointed bristles." Id. at 10. We are not persuaded by Appellants' arguments. A reference teaches away when it "criticize[s], discredit[s], or otherwise discourage[s] the solution claimed." In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Here, nothing in the prior art suggests that Ito's tapered, pointed bristles "should not" or "cannot" be combined with cylindrical bristles. In re Mouttet, 686 F.3d 1322, 1334 (Fed. Cir. 2012). And, although Ito criticizes standard pointed bristles, Ito does not criticize cylindrical bristles, such as those taught by Gross. Thus, we agree with the Examiner that Ito does not teach away from a combination of pointed and cylindrical bristles. Para- Ordnance Mfg., Inc. v. SGS Importers Int'!, Inc., 73 F.3d 1085, 1090 (Fed. Cir. 1995) (finding that a secondary prior art reference that failed to teach an element of the claimed invention did not teach away where "there [was] nothing about the [prior art] to warn a person of ordinary skill against using" that element). 7 Appeal2017-003667 Application 14/461,798 Next, Appellants argue that even "if one modified the Gross brush in view of Ito ... [the] combination would make all the bristles of the Gross brush pointed." Br. 10. We are not persuaded. "The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference." In re Keller, 642 F.2d 413,425 (CCPA 1981). The pertinent inquiry, instead, is whether "a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention." Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1361 (Fed. Cir. 2007). Here, the Examiner has provided sound reasoning that an ordinarily skilled artisan would have had reason to modify Gross' s vertical cylindrical bristles with the tapered, pointed bristles of Ito to better clean different areas of the mouth. Ans. 3--4. Specifically, the Examiner found that Ito's tapered, pointed bristles "permit the bristle tips of the vertical tufts to better reach areas between teeth thereby providing more thorough cleaning action and helping to prevent periodontal disease." Id. at 3 (citing Ito, 13:1-19). see also KSR, 550 U.S. at 417 (stating that "the mere application of a known technique to a piece of prior art ready for the improvement" would have been obvious). No record evidence suggests that modifying Gross' s vertical bristles from a cylindrical shape to a pointed, tapered shape as taught by Ito would have been outside the ordinarily skilled artisan's technical abilities. KSR, 550 U.S. at 421. Finally, Appellants assert that the "combination of vertical pointed bristles with slanted cylindrical bristles provides advantages previously unknown in the art." Br. 11. Appellants submit that the combination allows the slanted cylindrical bristles to "provide a sweeping surface cleaning" and the vertical pointed bristles "to penetrate more deeply into the interpoximal 8 Appeal2017-003667 Application 14/461,798 areas." Id. at 12. But Appellants provide no evidence to support these arguments, and thus they are not persuasive of Examiner error. See In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997) (attorney argument no substitute for evidence). We conclude that the Examiner established a prima facie case of obviousness that Appellants did not persuasively rebut. Thus, we affirm the Examiner's rejection of claims 18, 20-23, 25-30, and 32-35 under 35 U.S.C. § 103(a) for obviousness over Gross and Ito. SUMMARY We affirm the rejection of claims 18, 20-23, 25-30, and 32-35. TIME PERIOD FOR RESPONSE 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 9 UNITED STATES PATENT AND TRADEMARK OFFICE BEFORE THE PATENT TRIAL AND APPEAL BOARD Ex parte CHRISTINE GARBERS and ANDRE BRUNELLA Appeal2017-003667 Application 14/461,798 1 Technology Center 3700 Before DONALD E. ADAMS, JEFFREY N. FREDMAN, and KRISTI L. R. SA WERT, Administrative Patent Judges. ADAMS, Administrative Patent Judge, dissenting-in-part. DECISION ON APPEAL This Appeal under 35 U.S.C. § 134(a) involves claims 18, 20-23, 25- 30, and 32-35 (Br. 2). 2' 3 Examiner entered rejections under 35 U.S.C. §§ l 12(b) and 103(a). This Panel has jurisdiction under 35 U.S.C. § 6(b). 1 Appellants identify "Colgate-Palmolive Company, GABA International Holding AG, Grabelsmaltweg, 4106 Therwil, CH," as the real party in interest (Br. 2). 2 Pending claims 19, 24, and 31 stand withdrawn from consideration (Br. 2; Final Office Action mailed December 3, 2015 (Final Act.) 2). 3 Appellants' "Claims Appendix" incorrectly identifies claim 34 as withdrawn and fails to identify claim 31 as withdrawn (see Br. 15-16). Appeal2017-003667 Application 14/461,798 STATEMENT OF THE CASE Appellants' disclosure relates to "brush heads for tooth brushes" and, in particular, to an improvement in "a brush head for a tooth brush that has a handle part, a head part, and a bristle surface with tufts of bristles set therein" (Spec. ,r,r 2 and 5---6). Appellants' claims 18, 21, and 22 are representative and reproduced below: 18. A head for a toothbrush, the head having a longitudinal axis and comprising: a bristle surface with tufts of bristles set therein; wherein the tufts of bristles comprise a first tuft that is vertical on the bristle surface and a second tuft that is slanted on the bristle surface; and wherein the first tuft consists of pointed bristles and the second tuft consists of cylindrical bristles. (Br. 13.) (Id.) (Id.) 21. The head for a toothbrush of claim 18 further comprising a third tuft that is slanted on the bristle surface, the third tuft consisting of cylindrical bristles. 22. The head for a toothbrush of claim 21 wherein the second tuft is slanted forward on the bristle surface and wherein the third tuft is slanted backward on the bristle surface. 2 Appeal2017-003667 Application 14/461,798 Appellants' claims stand rejected as follows: Claims 22, 23, 26-28, 30, and 32-354 stand rejected as unpatentable under 35 U.S.C. § 112(b ). Claims 18, 20-23, 25-30, and 32-35 stand rejected under 35 U.S.C. § 103(a) for obviousness over Gross5 in view oflto. 6 Definiteness: ISSUE Does the preponderance of evidence support Examiner's conclusion that the terms slanted "forward" or "backward," as set forth in Appellants' claims, are indefinite? ANALYSIS According to Examiner, the terms slanted "'forward' and 'backward' are relative directions and [Appellants'] claim fails to define these directions with respect to the device" (Ans. 2). Examiner further asserts that the definitions, set forth in Appellants' Specification, for the terms slanting "forward" and "backward" are insufficient because the definitions are relative to the handle of the toothbrush and Appellants' claims focus on the part of the toothbrush wherein their inventive contribution to the art resides, i.e., the head of the toothbrush, and therefore Appellants' claims do not 4 The statement of the rejection in Examiner's Answer incorrectly includes withdrawn claim 31 (see Ans. 2). I consider this to represent a harmless typographical error and did not include withdrawn claim 31 in my deliberations. 5 Gross et al., WO 00/25631, published May 11, 2000. 6 Ito et al., U.S. Patent No. 5,533,277, issued July 9, 1996. 3 Appeal2017-003667 Application 14/461,798 address, or recite a limitation regarding, the handle of the toothbrush (see id. 6-7; cf Spec. ,r 15). Examiner's argument is not persuasive. As discussed above, Appellants disclosure relates to "brush heads for tooth brushes" and, in particular, to an improvement in "a brush head for a tooth brush that has a handle part, a head part, and a bristle surface with tufts of bristles set therein" (Spec. ,r,r 2 and 5-6 (emphasis added)). Thus, a person of ordinary skill in this art reading Appellants' claims in light of Appellants' Specification would understand that the head for a toothbrush, set forth in Appellants' claims, is for a toothbrush that comprises a handle and, thus, Appellants' Specification provides a clear definition of the direction of the forward or backward slant required by Appellants' claims (see generally Br. 5---6). See Hybritech, Inc. v. Monoclonal Antibodies, Inc., 802 F.2d 1367, 1385 (Fed. Cir. 1987). CONCLUSION The preponderance of evidence fails to support Examiner's conclusion that the terms slanted "forward" or "backward," as set forth in Appellants' claims, are indefinite. On this record, the rejection of claims 22, 23, 26-28, 30, and 32-35 under 35 U.S.C. § 112(b) cannot be sustained. Obviousness: ISSUE Does the preponderance of evidence relied upon by Examiner support a conclusion of obviousness? 4 Appeal2017-003667 Application 14/461,798 ANALYSIS Examiner finds that Gross discloses a brush head for a toothbrush that comprises, inter alia, rows of bristle tufts, wherein a first vertical transverse row of tufts that are vertical on the bristle surface, a second forward slanted row of tufts that are slanted forward on the bristle surface towards a distal free end of the brush head, and a third backward slanted row of tufts that are slanted backward on the bristle surface towards a handle end of the brush head and the first transverse row of tufts is positioned on the head between the second and third transverse rows of tufts. (Ans. 3) Examiner makes no finding regarding the cleaning capabilities of Gross' toothbrush. Examiner also makes no finding with regard to a disclosure in Gross regarding a toothbrush head comprising more than one type of bristle, i.e., pointed and cylindrical, or, even if Gross had contemplated different types of bristles, how different bristle types should be positioned on a toothbrush head (cf Br. 13 (Appellants' independent claim 18 requires a toothbrush head comprising, inter alia, a "first tuft consist[ing] of pointed bristles and [a] second tuft consist[ing] of cylindrical bristles"); see also Br. 15 (Appellants' independent claim 30, which also requires a toothbrush head comprising more than one type of bristle)). To the contrary, Examiner, at best, "interpreted" Gross' bristles to represent "cylindrical bristles" and expressly found that Gross did not teach tapered, or pointed, bristles (id. (emphasis added)). Examiner, therefore, relies on Ito to disclose a toothbrush [] comprising a series of vertical bristle tufts on a bristle surface of the toothbrush head [] wherein all of the vertical bristle tufts disposed on the bristle surface consisted of tapered, or pointed, bristles [] in order to permit the bristle tips of the vertical tufts to better reach areas between teeth [] 5 Appeal2017-003667 Application 14/461,798 thereby providing more thorough cleaning action and helping to prevent periodontal disease. (Ans. 3.) To be clear, Examiner relies on Ito to disclose a toothbrush that has one type of bristle (see id. at 7 (Examiner asserts that "Ito is not used to teach a combination of cylindrical and tapered bristles")). Based on the combination of Gross and Ito, Examiner concludes that, at the time Appellants' invention was made, it would have been prima facie obvious "to modify the device of Gross by providing the vertically projecting tufts consisting of tapered bristles in view of Ito in order to better clean different areas of the mouth during use" (id. at 4 ). In addition, Examiner concludes that the modification of Gross by Ito "results in all of the slanted bristle tufts consisting of cylindrical bristles ... and all of the vertical tufts consisting of pointed bristles" (id.). Examiner's conclusions are not persuasive (see Br. 8-12). As discussed above, Examiner made no finding on this record regarding the cleaning capabilities of Gross' bristles, thus, Examiner failed to provide an evidentiary basis on this record to support a conclusion that the use of different bristle types would necessarily result in cleaning "different areas of the mouth during use" (see Ans. 4; cf Br. 11 ). As further discussed above, Examiner made no finding on this record regarding a toothbrush head that comprises different bristle types, or even if, in the absence of hindsight, a person of ordinary skill in this art would have contemplated a toothbrush head comprising different bristle types, how the combination of Gross and Ito necessarily leads to the specific arrangement of different types of bristles on a toothbrush head that is required by Appellants' claimed invention (see Br. 10-12). Absent an evidentiary basis to support Examiner's conclusions I am compelled to agree with Appellants' contention that Examiner's 6 Appeal2017-003667 Application 14/461,798 conclusions are based in hindsight (see Br. 11 ("Ito provides no mention of combining vertical pointed bristles with slanted cylindrical bristles, and to assume that this combination would have been obvious is an exercise in improper hindsight")). In addition, on this record, Examiner has, at best, established that toothbrush heads comprising either cylindrical or pointed bristles where known in the art. Obviousness, however, requires more than a mere showing that the prior art includes separate references covering each separate limitation in a claim under examination. KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398,418, 127 S.Ct. 1727, 167 L.Ed.2d 705 (2007). Rather, obviousness requires the additional showing that a person of ordinary skill at the time of the invention would have selected and combined those prior art elements in the normal course of research and development to yield the claimed invention. Id. at 421, 127 S.Ct. 1727. Unigene Laboratories, Inc. v. Apotex, Inc., 655 F.3d 1352, 1360 (Fed. Cir. 2011). For the reasons set forth above, Examiner failed to establish an evidentiary basis on this record to support a conclusion that a person of ordinary skill in this art would have combined Gross and Ito in a manner that would have resulted in Appellants' claimed invention. To the contrary, Examiner simply established that different parts of Appellants' claimed invention were known in the art and, therefore, concluded that Appellants' claimed invention was obvious. "[R ]ejections on obviousness grounds[, however,] cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness." In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Thus, on this record, Examiner failed to meet "the initial burden, on review of the prior art or on any other ground, of presenting a 7 Appeal2017-003667 Application 14/461,798 primafacie case ofunpatentability." In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). Therefore, the obviousness rejection cannot be sustained. CONCLUSION The preponderance of evidence relied upon by Examiner fails to support a conclusion of obviousness. On this record, the rejection of claims 18, 20-23, 25-30, and 32-35 under 35 U.S.C. § 103(a) for obviousness over Gross in view of Ito cannot be sustained. SUMMARY On this record, Examiner failed to establish an evidentiary basis to support rejections under 35 U.S.C. §§ 112(b) or 103(a). See In re Oetiker, 977 F .2d at 1445 ("[T]he [E]xaminer bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability"). Thus, the rejections of record cannot be sustained. 8 Copy with citationCopy as parenthetical citation
