(App. Br. 2). 2 A written transcript of the Oral hearing will be entered into the record when the transcript is made available. Appeal 2018-000486 Application 14/016,581 2 The following rejections are presented for appeal: I. Claims 8–12 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo (JP 2008-207450 (citations taken from US 2010/0065983 A1)), Smith et al. (WO 93/06983; pub. Apr. 15, 1993, hereinafter “Smith”) and AAPA (Applicant Admitted Prior Art; taken from paragraphs (0002–0008) of applicant's publication US 2014/0001661). II. Claims 13, 15, 18, 20, 23, and 25 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Shimura (US 2005/0201101 A1; pub. Sept. 15, 2005). III. Claims 16, 21, and 26 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Ricking et al. (US 2005/0127543 A1; pub. June 16, 2005, hereinafter “Ricking”). IV. Claims 17, 22, and 27 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Seng et al. (US 2002/0056942 A1 pub. May 16, 2002, hereinafter “Seng”). V. Claims 13, 14, 16, 18, 19, 21, 23, 24, and 26 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA, and Leu et al. (US 2005/0045898 A1; pub. Mar. 3, 2005, hereinafter “Leu”). Appeal 2018-000486 Application 14/016,581 3 Appellant’s invention relates to a process for sealing a light emitting element. (Spec. 4:5–13). Claim 8 is illustrative of the subject matter on appeal and is reproduced below: 8. A process for sealing a light emitting element, comprising: providing a release film having a plurality of convex portions and/or concave portions formed on at least one surface of the release film; subsequently placing the provided release film in a cavity of a mold so as to cover the inner surface of the cavity of the mold and so that the surface having the convex portions and/or concave portions formed thereon faces a space in the cavity; placing the light emitting element in the cavity after the release film in placed in the cavity; and filling the cavity, in which the light emitting element has been placed, with a transparent resin to seal the light emitting element with the transparent resin. OPINION3 We have reviewed each of Appellant’s arguments for patentability. We will sustain the Examiner’s rejections for essentially those reasons expressed in the Answer and the Final Action. Rejection I Appellant argues that Smith discloses films used in molds to prepare large structures such as vehicle bumpers and therefore does not disclose or 3 Appellant’s arguments for the patentability of the independent claims are substantially the same. Appellant has also not presented arguments specific to every claim on appeal. Consequently, the non-argued claims will stand or fall with independent claim 8. See 37 C. F. R. § 41.37(c)(1)(iv). We limit our initial discussion to independent claim 8. Separately argued claims will be addressed. Appeal 2018-000486 Application 14/016,581 4 suggest employing the disclosed films to prepare fine structures as required by Kawakubo. (App. Br. 11). Appellant also argues the Examiner’s rejection is premised on hindsight. (Id.). Appellant’s arguments are not persuasive of reversible error. As established by the AAPA, release liner film formed from fluororesins elastomers were known to persons of ordinary skill in the art for the preparation of light emitting elements. (AAPA ¶¶ 4–5). Smith describes release films containing patterns placed within a mold to produce a product that replicates the pattern from the film. (Smith 2–3). Smith discloses this method allows a single mold to be more versatile by allowing products having different textures being formed from the same mold. (Smith 3, ll. 13–25). Both Smith and Kawakubo disclose thermoplastic resins are suitable for injection into the mold cavities. (Smith 3, ll. 1–4; Kawakubo ¶ 145). Consequently, due to the similarity in the suitable thermoplastic mold materials, a person of ordinary skill in the art would have reasonably expected that a mold release film having a pattern would have been suitable for use in Kawakubo’s mold to prepare fine structures. See, e.g., KSR Int’l Co. v. Teleflex, Inc., 550 US 398, 416 (2007) (“[W]hen 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.”); In re Siebentritt, 372 F.2d 566, 567–68 (CCPA 1967) (express suggestion to interchange methods which achieve the same or similar results is not necessary to establish obviousness); see also In re Kahn, 441 F.3d 977, 985–88 (Fed. Cir. 2006); In re O’Farrell, 853 F.2d 894, 903–04 (Fed. Cir. 1988) (“For obviousness under § 103, all that is required is a reasonable expectation of success.”) Appeal 2018-000486 Application 14/016,581 5 (citations omitted); In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“[T]he test [for obviousness] is what the combined teachings of the references would have suggested to those of ordinary skill in the art.”); In re Sovish, 769 F.2d 738, 743 (Fed. Cir. 1985) (skill is presumed on the part of one of ordinary skill in the art); In re Bozek, 416 F.2d 1385, 1390 (CCPA 1969) (“Having established that this knowledge was in the art, the examiner could then properly rely, as put forth by the solicitor, on a conclusion of obviousness ‘from common knowledge and common sense of the person of ordinary skill in the art without any specific hint or suggestion in a particular reference.’”). In arguing against the rejection of claims 8–12 Appellant relies on the arguments presented with regard to independent claim 8. (App. Br. 11). Appellant additionally argues claims 9 and 12 are patentable because the Examiner has not established that it was obvious to use fluororesin films— including films based on ethylene/tetrafluoroethylene copolymers— in the methods disclosed by Kawakubo and Smith. (App. Br. 12–13). As set forth above, both Kawakubo and Smith describe release film suitable for thermoplastic resins. As pointed out by the Examiner, the use of fluororesin films, including films based on ethylene/tetrafluoroethylene copolymers, as release films was known by persons of ordinary skill in the art. (Final Act. 5; AAPA ¶ 5). A person of ordinary skill in the art would have reasonably expected that a fluororesin mold release film having a pattern would have been suitable for use in Kawakubo’s mold to prepare Appeal 2018-000486 Application 14/016,581 6 fine structures because the AAPA discloses the fluororesin release films are durable against the flow of a resin. (AAPA ¶ 5). Rejection II Claims 13, 15, 18, 20, 23, and 25 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Shimura. Appellant’s arguments group the claims as follows (I) claims 13, 18 and 23; and (II) claims 15, 20, and 25. (App. Br. 14–20). We will address the claims as argued by Appellant. The Examiner finds Kawakubo does not expressly teach the convex/concave portion of the light guiding structure having inclination angle of 20 to 75 degrees as required by claims 13, 18, and 23. The Examiner relied upon Shimura for describing Fresnel lens that conventionally contain protrusions that continuously varies from an angle approaching 0° at a center to 90°. (Final Act. 6–7). The Examiner concluded it would have been obvious “to include inclination angles lying between 20 and 75 degrees for the benefit of redirecting the light from the source in a preferred direction as is conventional in the design of Fresnel lenses.” (Final Act. 7). Claims 13, 18, and 23 Appellant argues by employing a release film having concavities and/or convexities as recited in claims 13, 18, and 23 (having inclined surfaces with an inclination angle of from 20 to 75°), it is possible to obtain a light emitting device with improved front brightness compared to light emitting devices made using release films including concavities and/or Appeal 2018-000486 Application 14/016,581 7 convexities with smaller or larger inclination angles. Appellant argues this advantage is not recognized in the cited references. (App. Br. 17). Appellant’s argument does not persuade us of reversible error. As set forth above, we agree with the Examiner that it would have been obvious to perform a process for sealing a light emitting element comprising providing a release film having a plurality of convex portions and/or concave portions formed on at least one surface of the release film. Appellant has not refuted the Examiner’s position that it Fresnel lenses having inclination angles between 20° and 75° for the benefit of redirecting the light from the source was known to persons of ordinary skill in the art as exhibited by Shimura. (See Shimura ¶¶ 41, 55). Consequently, a person of ordinary skill in the art would have utilized a release film having an inclination angle lying between 0° and 90° for the production of light emitting devices having the benefit of redirecting the light from the source as proposed by the Examiner. Addressing this rejection, Appellant also relies on the experimental results in the present Specification and the Higuchi Declaration filed on October 5, 2016 (hereinafter “Decl.”), as providing evidence that light- emitting device is produced from release films having an inclination angle lying between 20° to 75° exhibit superior front brightness in comparison with light emitting devices having concavities and/or convexities with smaller or larger inclination angles. (App. Br. 17). Appellant has not demonstrated that the data presented in the Specification and the declaration exhibits unexpected results. We agree with the Examiner that the evidence present in this record does not address the inclination angles described by Shimura. (Ans. 14). We also agree with the Appeal 2018-000486 Application 14/016,581 8 Examiner that claim 13 is not limited to a specific pattern having grooves with a V-form cross section and a depth as specified in the exemplary embodiments of the Higuchi Declaration and Specification. (See Ans. 14; see also generally Decl. ; Spec. 12–14 (Examples 2 and 3)). Appellant has not explained how the narrow showing presented reveals information regarding the breadth of the claimed invention that specifies an inclination angle lying between 20° to 75°. Consequently, the alleged improvement in brightness is not commensurate in scope with the claimed invention that is not limited to V-form cross section and a depth as specified in the exemplary embodiments. Thus, Appellant has failed to direct us to evidence that establishes a patentable distinction is achieved utilizing an inclination angle lying between 20° to 75° that is reasonably commensurate with the scope of protection sought by the claims on appeal. Cf. In re Harris, 409 F.3d 1339, 1344 (Fed. Cir. 2005) (“Even assuming that the results were unexpected, Harris needed to show results covering the scope of the claimed range. Alternatively Harris needed to narrow the claims.”); In re Greenfield, 571 F.2d 1185, 1189 (CCPA 1978) (“Establishing that one (or a small number of) species gives unexpected results is inadequate proof, for ‘it is the view of this court that objective evidence of non-obviousness must be commensurate in scope with the claims which the evidence is offered to support.’”) (quoting In re Tiffin, 448 F.2d 791, 792 (CCPA 1971)); In re Woodruff, 919 F.2d 1575, 1578 (Fed. Cir. 1990) (Indicating that in cases in which the difference between the claimed invention and the prior art is some range or other variable within the claims, the applicant must show that the particular range is critical, generally by showing that the claimed range achieves unexpected results relative to the prior art range.). In summary, Appellant Appeal 2018-000486 Application 14/016,581 9 has not adequately explained how the evidence presented in the Declaration and the Specification is representative of the scope of the claimed invention. Finally, we again emphasize that, although secondary considerations of nonobviousness must be taken into account, they do not necessarily control the obviousness conclusion. Pfizer, Inc. v. Apotex, 480 F.3d 1348, 1372 (Fed. Cir. 2007). Here, the record establishes the process of utilizing a release film having an inclination angle lying between 0° and 90° for the production of light emitting devices having the benefit of redirecting the light from the source would have been recognized by persons of ordinary skill in the art. Claims 15, 20, and 25 In arguing against the rejection of claims 15, 20, and 25, Appellant essentially relies on the arguments presented with regard to claims 13, 18, and 23 regarding the inclusion of concavities and/or convexities patterns in the release film. (App. Br. 19). As stated above, the arguments regarding including concavities and/or convexities in the release film presented against the rejection of independent claims 8, 10, and 11 were not found persuasive. Additionally as explained above, a person of ordinary skill in the art would have recognized the suitability of modifying the concavities and/or convexities patterns in the release film to produce a light emitting device having the benefit of redirecting the light from the source in a preferred direction as is conventional in the design of Fresnel lenses. Accordingly, for Appeal 2018-000486 Application 14/016,581 10 the reasons we stated above, we determine Appellant’s arguments are not persuasive of reversible error. Rejections III and IV Claims 16, 21, and 26 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Ricking; and claims 17, 22, and 27 are rejected under 35 USC § 103(a) over Kawakubo in view of Smith, AAPA, and Seng. In arguing against the rejections III and IV, Appellant relies on the same arguments presented against the combination of Kawakubo, Smith, and AAPA for independent claims 8, 10, and 11 additionally arguing that the additional reference Ricking and/or Seng fails to suggest providing a release film having a plurality of convex portions and/or concave portions on a surface, placing the release film in a cavity of a mold, and sealing a light emitting element in the mold. (App. Br. 21–22). As stated above, the arguments regarding including concavities and/or convexities in the release film presented against the rejection of independent claims 8, 10, and 11 were not found persuasive. Additionally, as explained above, a person of ordinary skill in the art would have recognized the suitability of modifying the concavities and/or convexities patterns in the release film to produce a light emitting device having the benefit of redirecting the light from the source in a preferred direction as is conventional in the design of Fresnel lenses. Accordingly, for the reasons we stated above and those presented by the Appeal 2018-000486 Application 14/016,581 11 Examiner, we determine that Appellant’s arguments are not persuasive of reversible error. Claims 17 and 27 Appellant argues claims 17 and 27 describe the thickness of the release film is at most 150 µm. Appellant also argues that films having this thickness having improved capability to conform to the shape of the mold cavity. (App. Br. 23). Appellant acknowledges that the Examiner cited Seng for describing release films having a thickness ranging from 10 to 100 µm. (App. Br. 23). We agree with the Examiner that Appellant has not established the criticality of the thickness of the release film. (Ans. 19). It is well settled that where patentability is predicated upon a change in a condition of a prior art composition, such as a change in size, concentration or the like, the burden is on the Appellant to establish with objective evidence that the change is critical, i.e., it leads to a new, unexpected result. In re Woodruff, 919 F.2d 1575, 1578 (Fed. Cir. 1990); In re Aller, 220 F.2d 454, 456 (CCPA 1955). Rejection V Claims 13, 14, 16, 18, 19, 21, 23, 24, and 26 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Kawakubo, Smith, AAPA and Leu. Appellant’s arguments group the claims as follows: (I) claims 13, 18, and 23; (II) claims 14, 19, and 24; and (III) claims 16, 21, and 26. (App. Br. 25–27). We will address the claims as argued by Appellant. The Examiner finds Kawakubo does not expressly teach the convex/concave portion of the light guiding structure having inclination Appeal 2018-000486 Application 14/016,581 12 angle of 20° to 75° as required by claims 13, 18, and 23. The Examiner relied upon Leu for its teaching that the shape of the encapsulation is selected so the LED may emit light at a wide emission angle. (Final Act. 10; Leu ¶ 6 ). The Examiner concluded it would have been obvious “to have an encapsulant of the shape described by Leu for the benefit of producing a device having a broad angle of emission.” (Final Act. 10). Claims 13, 18, and 23 Appellant argues that the Examiner has not provided an adequate explanation why the skilled artisan would have made the proposed modification. (App. Br. 25). Appellant’s arguments are not persuasive of reversible error. The prior art cited in this record establishes that it would have been obvious to perform a process for sealing a light emitting element comprising providing a release film having a plurality of convex portions and/or concave portions to provide a light emitting device having varied angles of emission. As stated above, Leu was cited for its teaching that the shape of the encapsulation is selected so that the LED may emit light at a wide emission angle. (Final Act. 10; Leu ¶ 6 ). Leu further states the V-shaped members can instead be Fresnel lens or convex protrusions. (Leu ¶ 24). The Examiner explains that “the properties of emission are an engineering design element which would have been considered by a skilled artisan at the time of invention. (Ans. 18). Appellant has not argued that Leu does not teach the convex/concave portion of the light guiding structure having an inclination angle of 20° to 75°. Furthermore, Appellant’s argument (Reply Br. 8) that Leu itself does not suggest the Examiner’s proffered modification to Appeal 2018-000486 Application 14/016,581 13 Kawakubo is not persuasive. Here, we emphasize that the “obviousness analysis cannot be confined by a formalistic conception of the words teaching, suggestion, and motivation, or by overemphasis on the importance of published articles and the explicit content of issued patents.” KSR, 550 U.S. at 419. Claims 14, 19, and 24 and claims 16, 21, and 26 Addressing claims 14, 19, and 24, Appellant argues: Each of these claims, in addition to the features of the claims from which they depend, requires that an average interval of adjacent local peaks of the convex portions or an average interval of adjacent local bottoms of the concave portions is from 4 to 200 µm, and an average height of the convex portions or an average depth of the concave portions is from 2 to l 00 μm. (App. Br. 25). Addressing claims 16, 21. And 26, Appellant argues “[e]ach of these claims, in addition to the features of the claims from which they depend, requires that the convex portions are pyramid projections, and the concave portions are pyramid gaps.” (App. Br. 27). Addressing both of these groupings of claims, Appellant argues the Examiner has not provided an adequate explanation of the rejection. (App. Br. 25 and 27). The Examiner cited Leu teaching light emitting device having concave portions and convex portions that results in the device is having the benefit of a broad angle of emission. As stated above, the prior art cited in this record establishes that persons of ordinary skill in the art would have recognized that varying the concave portions and the convex portions results in light emitting device is having varied angles of emission. Appellant has Appeal 2018-000486 Application 14/016,581 14 not established the claimed three-dimensional appearance of the concavity or convexity or the claimed average interval of adjacent local peaks or average interval of adjacent local bottoms results in a light emitting device having unexpected results. It is well settled that where patentability is predicated upon a change in a condition of a prior art composition, such as a change in size, concentration or the like, the burden is on the Appellant to establish with objective evidence that the change is critical, i.e., it leads to a new, unexpected result. See Woodruff and Aller, supra. CONCLUSION For the reasons given above, we sustain the Examiner’s obviousness rejections of claims 8–27. DECISION The Examiner’s obviousness rejections 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)(1). AFFIRMED Copy with citationCopy as parenthetical citation
