GRIFFIN Appeal 2018-004588 Application 14/126,056 Technology Center 2800 Before JACQUELINE WRIGHT BONILLA, Deputy Chief Administrative Patent Judge, and GEORGIANNA W. BRADEN and MICHELLE N. ANKENBRAND, Administrative Patent Judges. BRADEN, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 27–30.2 We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as Visioneering Technologies, Inc. Appeal Br. 1. 2 Claims 1–5, 15–26, and 33–41 are cancelled. Appeal Br. A-1 (Claims Appendix); Mar. 15, 2016 Amendment 5 . Appeal 2018-004588 Application 14/126,056 2 CLAIMED SUBJECT MATTER The claims are directed to a method of treating the progression of myopia by using a lens that induces an aperture. Spec. ¶¶ 10–11; Appeal Br. A-1 (Claims Appendix). The lens includes a power distribution having a central point with distance vision correcting power and a rapidly-increasing power distribution immediately outside of the central point that creates a blurred region immediately outside of the clear distance vision area. Spec. ¶ 16. This power distribution causes an induced “aperture” without an actual physical aperture. Id. ¶ 25. According to the Specification, an induced aperture with the blurred region immediately outside of the clear distance vision area produces similar effects to the user as a physical pinhole without suffering from the loss of light and increased diffraction inherent in physical pinholes. Id. ¶ 11. One aspect of the claimed invention is illustrated in Figure 8, reproduced below. Figure 8, above, shows the distribution of optical power rise as a function of radial dimension (x) from the apex (or center) of a lens. Spec. ¶ 26. According to the Specification, “centrally located distance vision region 60 has a power distribution that varies within a power range that is effective Appeal 2018-004588 Application 14/126,056 3 with the apical power for distance vision correction.” Spec. ¶ 26, Fig. 8. The Specification states “[t]he distribution power rise initially increases continuously but slowly with increasing radius to provide an effective area for distance power needed.” Id. ¶ 26, Fig. 8. Claim 27, reproduced below, is the only independent claim pending in the application and is illustrative of the claimed subject matter: 27. A method for treating myopia and myopic progression, comprising the steps of: determining a user has myopia; providing a lens having a central region about an apex of the lens that yields clear distance vision, and an optical blur region immediately surrounding the central region that yields an unfocused optical image; and positioning the lens on an eye of a user to provide an induced aperture and an increased depth of focus when used to correct vision of the user, relative to when the lens is not positioned on the eye of the user, wherein the central region includes an optical surface creating a power distribution that varies smoothly from an apical power at a central point on the apex designed for distance correction through increasing power immediately surrounding the central point to inhibit or reduce myopic progression in the eye, relative to when the lens is not positioned on the eye of the user. Appeal Br. A-1 (Claims Appendix). As shown above in independent claim 27, Appellant’s claims limit the invention to providing a lens wherein the central region [of the lens] includes an optical surface creating a power distribution that varies smoothly from an apical power at a central point on the apex designed for distance correction through increasing power immediately surrounding the central point to inhibit or reduce myopic progression in the eye, relative to when the lens is not positioned on the eye of the user.

ANALYSIS Claims 27–30 stand rejected under 35 U.S.C. § 103(a) as being obvious over the Examiner’s combination of Holden and Griffin ’814, alone or combined with other references. Non-Final Act. 3–5; Appeal Br. 7. These same claims also stand rejected under 35 U.S.C. § 103(a) as being obvious over the Examiner’s combination of Griffin ’918 and Holden, alone or combined with other references. Non-Final Act. 5–7; Appeal Br. 7. 1. Holden and Griffin ’814 a. The Teachings of Holden In rejecting independent claim 27 under § 103(a), the Examiner relies on the combined teachings of Holden and Griffin ’814, but specifically relies on Holden for teaching (1) a method for treating myopic progression, (2) a “central region,” and (3) an “optical blur region immediately surrounding the central region that yields an unfocused optical image” as recited by claim 27. Non-Final Act. 3; Ans. 5. Holden describes techniques related to controlling the progression of myopia using the relative positioning of optical zones on a contact lens, which are shown in Figures 1B and 5 reproduced below. Holden, Title, Abstract, Figs. 1B, 5. Appeal 2018-004588 Application 14/126,056 6 In Figures 1B and 5 above, Holden provides for large central zone 20, annular peripheral optical zone 24 surrounding central zone 20, and smooth transition zone 30 located between optical zones 20 and 24. Id. ¶ 31, Figs. 1B, 5. Holden discloses that smooth transition region 30 does not perform an optical function. Id. ¶ 31. The Examiner states that the claims do not specify how much of the “central region” yields clear vision. Ans. 5. The Examiner further states that “none of the shape/size of the aperture is claimed, and while Holden discusses the central region can be matched to the pupil size, Holden does not limit the size/shape to only such a specification.” Id. at 6–7 (citing Holden ¶¶ 19, 32, 33). Therefore, the Examiner finds that combining Holden’s optical region 20 and non-optical region 30 would read on the claimed “central region,” which is immediately surrounded by an optical blur region (made of regions 24 and 58). Non-Final Act. 3. The Examiner finds such a combination entirely consistent with the Specification and the pending claims. Id.; Ans. 5. Thus, the Examiner concludes that the combination of regions 20 and 30 equate to the recited limitation “wherein the central regions includes . . . a power distribution that varies smoothly.” Ans. 5 (citing Holden ¶¶ 31, 36). Appeal 2018-004588 Application 14/126,056 7 Appellant disputes the Examiner’s position and argues that Holden fails to disclose (1) an optical blur region immediately surrounding the central region, or (2) a central region with an optical surface creating a power distribution that varies smoothly from an apical power at a central point on the apex designed for distance correction through increasing power immediately surrounding the central point to inhibit or reduce myopic progression in the eye, as required by claim 27. Appeal Br. 9–10. Appellant specifically argues that Holden’s regions 24 and 58 are “not located immediately surrounding the alleged central point that yields clear distance vision (20) and are in fact spaced from the central point (20) by a blend transition region 30.” Id. at 10 (emphasis omitted). Appellant further argues that “the power differential in Holden does not change at all surrounding the central point, and is instead flat for 3.5 mm. The alleged blur region of Holden is therefore not located ‘immediately surrounding the central point,’” as claimed. Id. at 11 (citing Holden, Fig. 3). We agree with Appellant because the claims require “wherein the central region includes an optical surface creating a power distribution that varies smoothly from an apical power at a central point on the apex designed for distance correction through increasing power immediately surrounding the central point to inhibit or reduce myopic progression in the eye.” Appeal Br. A-1 (Claims Appendix) (emphasis added). Holden does not teach or suggest increasing power immediately surrounding a central point on the apex of a lens. Rather, as shown in Figure 4, reproduced below, Appeal 2018-004588 Application 14/126,056 8 Holden discloses a flat power differential from the center point of a lens until 3.5 mm from the center point. Holden ¶¶ 40–41, Fig. 4.3 Figure 4 above illustrates that there is no power change in the central optical zone immediately surrounding the central point (0.0) of the lens because the power does not start to increase until the lens reaches the transition zone. See Holden ¶ 41, Fig. 4. Even if we agree with the Examiner’s interpretation of the “central region” as including central optical zone 20 and transition zone 30, such an interpretation would still fail to account for “increasing power immediately surrounding the central point to inhibit or reduce myopic progression in the eye” as the claims require. This is because 3 Figure 4 is a graph of relative optical power with respect to lens diameter for the optical zones of the contact lens of the second lens example disclosed in Holden. Holden ¶ 28. Holden states that “[t]he principal differences between the first and second examples lie in the design of the transition zone 130 and peripheral zone 124 of lens 110.” Id. ¶ 40. Thus, for the purposes of our analysis, central optical zone 120 in example two is the same as central optical zone 20 in example one, while transition zone 160 serves the same purpose as transition zone 30, and peripheral optical zone 124 functions similarly to peripheral optical zone 24. Id. ¶¶ 31–32, 40– 41 Appeal 2018-004588 Application 14/126,056 9 the central region of Holden cannot function as a point. A “point,” under its plain and ordinary meaning, is “an exact position or location on a plane surface.” See www.mathopenref.com;4 www.mathsisfun.com;5 www.mathplanet.com;6 see also www.merriam-webster.com (defining “point” as “a geometric element that has zero dimensions and a location determinable by an ordered set of coordinates”).7 Holden discloses that “the diameter of central zone 20 is substantially matched to the normal pupil size.” Holden ¶ 32. Thus, even if central zone 20 is not exactly the size of a normal pupil, each of Holden’s disclosures regarding the central zone indicates it is much larger than a “central point.” See Holden ¶¶ 31, 32, 34, Figs. 1B, 2B. b. The Teachings of Griffin ’814 In rejecting independent claim 27 under § 103(a), the Examiner relies on the combined teachings of Holden and Griffin ’814, but specifically relies on Griffin ’814 for teaching an induced aperture leans with a “central region” of distance correction with a varying power distribution that varies smoothly from an apical power at a central point. Non-Final Act. 3–4; Ans. 8. Griffin ’814 describes a multifocal contact lens for treating presbyopia that includes an induced aperture created by smoothly increasing power 4 Math Open Reference, https://www.mathopenref.com/point.html (last visited April 21, 2020). 5 Math is Fun, https://www.mathsisfun.com/definitions/point.html (last visited April 21, 2020). 6 Math Planet, https://www.mathplanet.com/education/geometry/points,- lines,-planes-and-angles/an-introduction-to-geometry (last visited April 21, 2020). 7 Merriam-Webster Online Dictionary, https://www. https://www.merriam- webster.com/point.html (last visited April 21, 2020). Appeal 2018-004588 Application 14/126,056 10 from a central region outwards. Griffin ’814, Figs. 1–2b, 1:52–58, 5:10–26, 7:15–40. Figure 1 of Griffin ’814 is reproduced below. Figure 1 of Griffin ’814, reproduced above, graphs the local optical power distribution of a lens (the vertical axis) as a function of radial dimension (the horizontal axis) from the apex of the lens disclosed in Griffin ’814. With regards to Figure 1, Griffin ’814 further discloses: From the design level 28, the power distribution 20 rapidly increases with radius in what is termed an optical step 26. The rise in the power in the optical step 26 is sufficiently high that, during distance viewing, the cortical aspect of a user’s vision system is unable to resolve through the surrounding blur of the optical step 26. As a result, the user is induced to view distant objects solely through the distance vision region 22. The perceived effect is similar to that known to be achieved by small aperture devices such as pinholes devices. The optical device having this effect, resulting from the combination of the distance vision region and surrounding optical step, is referred to here as an induced effective aperture. Griffin ’814, 5:36–48. Based on the above disclosure, the Examiner finds that Griffin ’814 teaches an “induced aperture” as well as “a central region of distance correction with a varying power that varies smoothing [sic] from an apical power at a central point.” Non-Final Act. 3–4; Ans. 7–8. Appellant does Appeal 2018-004588 Application 14/126,056 11 not contest the Examiner’s finding regarding Griffin ’814 and we agree with that finding. c. Rationale to Combine the Prior Art and their Optical Mechanisms According to the Examiner, “[t]he motivation to provide a lens with such a smoothly varying power from a central point on the apex, as discussed in [Griffin ’814], includes providing optical power for correcting vision over a continuous distance range of infinity to near sight distances ([Griffin ’814] col. 3:65-col. 4:2; col. 5:50-55) and ensuring no diffraction effects in the distance vision region ([Griffin ’814] col. 4:13-16).” Ans. 8. In other words, the Examiner finds that Griffin ’814 provides the motivation to combine Holden and Griffin ’814. Id. The Examiner, therefore, concludes that it would have been obvious to one of ordinary skill in the art at the time of the invention to combine the teachings of Holden and Griffin ’814. Id. Appellant contends Griffin ’814 and Holden would not have been obvious to combine because Griffin ’814 and Holden use vastly different optical mechanisms, and modifying one lens to operate like the other would change the principle of operation of each lens. Appeal Br. 15. Appellant specifically argues that the lens of Holden performs its function using a peripheral effect, namely, refracting light at a periphery of the lens toward the retina, while Griffin ’814 (and the claimed invention) involves a central effect where an induced aperture increases depth of focus and reduces accommodative lag. Id. According to Appellant, “[m]odifying Holden to use a central effect would change the principle of operation of Holden from a peripheral effect to a central effect – virtually the opposite of Holden’s teachings. The same holds true for modifying [Griffin ’814] to include the Appeal 2018-004588 Application 14/126,056 12 peripheral effect of Holden.” Id. at 15–16. Appellant concludes that “[t]he combination of Holden and [Griffin ’814], or conversely [Griffin ’814] and Holden, is therefore improper.” Id. at 16. Appellant further contends that a person of ordinary skill in the art would not have used an induced aperture or the teachings of Griffin ’814 to treat myopia or to stop the progression of myopia. Appeal Br. 14. To support its position, Appellant relies on Griffin ’814’s disclosure that “[c]lear distance vision requires clear optics and the preponderant myopic population will not tolerate distance blur” such as that the lens in Griffin ’814 creates. Id. (quoting Griffin ’814, 3:17–26) (emphasis added). In response to Appellant’s challenge, the Examiner maintains the findings regarding Holden and Griffin ’814. According to the Examiner, “correction of myopia is done by providing clear distance vision, which is exactly what [Griffin ’814] proposes to do. One of ordinary skill in the art would consider the lens of [Griffin ’814] to be successful for treating myopia since [Griffin ’814] explicitly states it provides clear distance vision.” Ans. 9 (citing Griffin ’814, 3:65–4:1, 5:18–20). Regarding Appellant’s argument that the claimed invention involves a “central effect,” while Holden is a “peripheral effect,” the Examiner notes such features are not claimed. Id. at 10. Furthermore, the Examiner finds that “[t]he combination of Holden in view of [Griffin ’814] would not change the operation since both Holden and [Griffin ’814] operate in the same manner” because each lens creates “a central region with clear distance vision and a blurred region surrounding that to provide a peripheral blurred image.” Id. Although we agree with the Examiner that the claims do not recite the mode of operation (peripheral versus central effect), we are persuaded by Appeal 2018-004588 Application 14/126,056 13 Appellant’s arguments. Specifically, we agree with Appellant that Holden and Griffin ’814 operate differently, i.e., involve different principles of operation, because (1) Holden discloses a lens with a clear distance region over substantially the entire pupil that refracts peripheral rays of light to provide its intended effect (see Holden ¶ 11), whereas (2) Griffin ’814 discloses a lens with an induced aperture created at a center point of the eye that increases depth of focus and reduces accommodative lag (see Griffin ’814, Figs. 2a, 2b). “If the proposed modification or combination of the prior art would change the principle of operation of the prior art invention being modified, then the teachings of the references are not sufficient to render the claims prima facie obvious.” MPEP § 2143.01(VI) (citing In re Ratti, 270 F.2d 810, 813 (CCPA 1959)). The Examiner proposes replacing Holden’s central region with Griffin ’814’s “induced aperture” and “a central region of distance correction with a varying power that varies smoothing [sic] from an apical power at a central point.” Non-Final Act. 3–4. But we agree with Appellant that modifying Holden so that power varies smoothly from the central point outward would change the basic principle under which Holden was designed to operate (i.e., it would no longer work by using refracted peripheral rays of light). Ratti, 270 F.2d at 813. We agree, therefore, that the Examiner’s proposed modification of Holden with the teachings of Griffin ’814 would change the principle of operation of Holden. Additionally, we find that how the lenses operate informs whether a person of ordinary skill in the art would have looked to combine the specific teachings. We do not agree with the Examiner that a person of ordinary skill in the art would have had reason to combine the disparate teachings of Appeal 2018-004588 Application 14/126,056 14 Holden with those of Griffin ’814 when the references involve such different principles of operation. To find otherwise would risk the use of impermissible hindsight analysis. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (“Any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but so long as it takes into account only knowledge which was within the level of ordinary skill [in the art] at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure, such a reconstruction is proper.” (emphasis added)); MPEP § 2142 (“impermissible hindsight must be avoided and the legal conclusion must be reached on the basis of the facts gleaned from the prior art”). For these reasons, we reverse the Examiner’s obviousness rejection of claim 27 under 35 U.S.C. § 103(a) as unpatentable over Holden and Griffin ’814. The Examiner similarly relies on the combination of Holden and Griffin ’814 regarding the same limitations when rejecting claim 28, which depends directly from claim 27. Non-Final Act. 4; Ans. 14. For the same reasons discussed above regarding claim 27, we reverse the Examiner’s obviousness rejection of claim 28 under 35 U.S.C. § 103(a) as unpatentable over Holden and Griffin ’814. 2. Holden, Griffin ’814, and Roffman Claim 29 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Holden, Griffin ’814, and Roffman. Non-Final Act. 4–5; Appeal Br. 7; Ans. 14. Claim 29 indirectly depends from independent claim 27 and additionally recites “wherein the depth of focus is within +0.25 to +1.00 diopters.” Appeal Br. A-1 (Claims Appendix). Appeal 2018-004588 Application 14/126,056 15 Roffman is directed to aspheric toric lens designs. Roffman, Title, Abstract. The Examiner relies on Roffman for its teachings related to lenses that provide an increased depth of focus at +0.25 to +1.00 diopters. Non- Final Act. 4–5 (citing Roffman 4:40–42). Because Roffman does not remedy the deficiencies of Holden and Griffin ’814, we reverse the Examiner’s obviousness rejection of claim 29 under 35 U.S.C. § 103(a) as unpatentable over Holden, Griffin ’814, and Roffman for the same reasons described above. 3. Holden, Griffin ’814, and Back Claim 30 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Holden, Griffin ’814, and Back. Non-Final Act. 5; Appeal Br. 7; Ans. 14. Claim 30 indirectly depends from independent claim 27 and additionally recites, “wherein the user has a reduction in accommodative lag of about +0.25 to about +1.00 diopters relative to when the lens is not positioned on the eye of the use.” Appeal Br. A-1 (Claims Appendix). Back is directed to reducing accommodative error in contact lenses. Back, Title, Abstract. The Examiner relies on Back for its teachings related to using ophthalmic lenses for reducing accommodative lag of at least +0.250 to about +1.000. Non-Final Act. 5 (citing Back 7:29–40, 12:60–67). Because Back does not remedy the deficiencies of Holden and Griffin ’814, we reverse the Examiner’s obviousness rejection of claim 30 under 35 U.S.C. § 103(a) as unpatentable over Holden, Griffin ’814, and Back for the same reasons described above. Appeal 2018-004588 Application 14/126,056 16 4. Griffin ’918 and Holden The Examiner’s second rejection of independent claim 27 under § 103(a) relies on the combined teachings of Griffin ’918 and Holden. The Examiner cites to Griffin ’918 for almost all of the elements recited in claim 27. Non-Final Act. 6; Ans. 11–12. Griffin ’918 describes an ophthalmic lens with an induced aperture. Griffin ’918, Title, Abstract. The reference discloses a lens having a central region about an apex of the lens and an optical blur region immediately surrounding a central region that yields an unfocused optical image. Griffin ’918 6:10–15, Figs. 1–26, 27. The lens of Griffin ’918 is shown in Figure 2a, while the power distribution of the lens is charted in Figure 2b. Figures 2a–b are reproduced below. As shown in Figure 2b above, lens 30 includes central region 32 with power distribution 32a corresponding to the distance vision region 22, and optical step 26. Griffin ’918, 10:50–53. The focal power in the central region rises steeply in optical step 26 to create an induced aperture. Id. at10:55–57. The maximum power reached is the specifically required near vision power 34. Id. at 10:57–58. Griffin ’918 teaches positioning the lens on an eye of a user to provide an induced aperture and an increased depth of focus when used to Appeal 2018-004588 Application 14/126,056 17 correct vision of the user relative to when the lens is not used. Id. at 4:15– 24, 5:54–67, 6:15–21, Figs. 1–14b. The only elements recited in claim 27 that the Examiner does not find in Griffin ’918 are “determining a user has myopia” and “to inhibit or reduce myopic progression in the eye.” Ans. 12; Non-Final Act. 6 (citing Holden ¶¶ 2, 11, Figs. 5, 6 for those elements). As discussed above, Holden describes techniques related to controlling the progression of myopia using the relative positioning of optical zones on a contact lens. Holden ¶ 31, Figs. 1B, 5. The Examiner finds that the combined teachings of Griffin ’918 and Holden would have rendered the claim invention obvious to a person of ordinary skill in the art. Ans. 12; Non-Final Act. 6. According to the Examiner, [t]he motivation to combine [Griffin ’918] and Holden comes from the art of Holden. Holden teaches lenses having a clear central region and blurred (out of focus) peripheral regions are well known in the art for the purpose of introducing blurring to the retina such that the eye is mitigated from elongating and thus prevents myopia progression (Holden para. [0005], [0011]). Ans. 12. Appellant again contends Griffin ’918 and Holden would not have been obvious to combine and presents the same arguments for reversal of this rejection that Appellant presents in connection with the Examiner’s rejection of claim 27 over Holden and Griffin ’918, as discussed above. See Appeal Br. 14–16 In response to Appellant’s challenge, the Examiner maintains the findings regarding Griffin ’918 and Holden. According to the Examiner, Appeal 2018-004588 Application 14/126,056 18 [t]he motivation to combine the teachings comes from the art of Holden who teaches lenses having a clear central region and blurred (out of focus) peripheral regions are well known in the art for the purpose of introducing blurring to the retina such that the eye is mitigated from elongating and thus prevents myopia progression. Ans. 13 (citing Holden ¶¶ 5, 11). The Examiner also finds that Appellant’s remarks concerning “central effect” and “peripheral effect” are not persuasive because the Examiner states that “each of [Griffin ’918], Holden, and the claimed invention are directed to both effects - a central clear distance vision region and a peripheral blurred region.” Id. We do not agree with the Examiner for multiple reasons. First, we do not agree with the Examiner that the claimed invention is directed to a central clear distance vision region and a peripheral blurred region. Rather, we find that the claimed invention uses a central effect similar to Griffin ’918. Second, we find that Holden discloses a lens with a clear distance region over substantially the entire pupil and it refracts peripheral rays of light to provide its intended effect (see Holden ¶ 11), whereas Griffin ’918 discloses the use of an induced aperture located at a center point of the eye that increases depth of focus and reduces accommodative lag (see Griffin ’918, Figs. 2a, 2b). Any attempt to modify the teachings of Griffin ’918 to use Holden’s refracted peripheral rays of light would change the basic principle under which Griffin ’918 works (i.e., it would no longer work by varying power smoothly from the center of the lens outward). Ratti, 270 F.2d at 813. We, therefore, conclude that the Examiner’s Appeal 2018-004588 Application 14/126,056 19 proposed modification of Griffin ’814 with the teachings of Holden is inappropriate. Additionally, we find that how the lenses operate informs whether a person of ordinary skill in the art would have looked to combine the specific teachings. Here, as we explain above, the Examiner’s rejection appears to be based on impermissible hindsight. For these reasons, we reverse the Examiner’s obviousness rejection of claim 27 under 35 U.S.C. § 103(a) as unpatentable over Griffin ’918 and Holden. The Examiner similarly relies on the combination of Griffin ’918 and Holden regarding the same limitations when rejecting claim 28, which depends directly from claim 27. Non-Final Act. 6; Ans. 14. For the same reasons discussed above regarding claim 27, we reverse the Examiner’s obviousness rejection of claim 28 under 35 U.S.C. § 103(a) as unpatentable over Griffin ’918 and Holden. 5. Griffin ’918, Holden, and Roffman Claim 29 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Griffin ’918, Holden, and Roffman. Non-Final Act. 6–7; Appeal Br. 7; Ans. 14. The Examiner relies on Roffman for its teachings related to lenses that provide an increased depth of focus at +0.25 to +1.00 diopters. Non-Final Act. 6–7 (citing Roffman 4:40–42). Because Roffman does not remedy the deficiencies of Griffin ’918 and Holden, we reverse the Examiner’s obviousness rejection of claim 29 under 35 U.S.C. § 103(a) as unpatentable over Griffin ’918, Holden, and Roffman for the same reasons described above. Appeal 2018-004588 Application 14/126,056 20 6. Griffin ’918, Holden, and Back Claim 30 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Griffin ’918, Holden, and Back. Non-Final Act. 7; Appeal Br. 7; Ans. 14. The Examiner relies on Back for its teachings related to using ophthalmic lenses for reducing accommodative lag of at least +0.250 to about +1.000. Non-Final Act. 7 (citing Back 7:29–40, 12:60–67). Because Back does not remedy the deficiencies of Griffin ’918 and Holden, we reverse the Examiner’s obviousness rejection of claim 30 under 35 U.S.C. § 103(a) as unpatentable over Griffin ’918, Holden, and Back for the same reasons described above. CONCLUSION The Examiner’s rejections of pending claims 27–30 under 35 U.S.C. § 103(a) are REVERSED.
