Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein.

      “Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v.

We conclude that Petitioner and its expert navigate along one path out of many to the particular redesign they propose using improper result-oriented hindsight as a guide. Petitioner’s expert’s recitation of the at least 25 steps taken to journey from the original Fukaya design to the modified design is instructive: (i) inputting into lens design software the original Fukaya lens parameters; (ii) evaluating its off-axis performance; (iii) increasing the number of analysis field points; (iv) deciding to focus on lenses 5–7, which requires that all aspherics be varied; (v) modifying lens 6 aspherics; (vi) adding CARD operands in the merit function to change the curvature radius values on the lens surfaces; (vii) adding FTGT operands to control spacing between the lenses and lens thicknesses; (viii) adjusting CENY to set the field height; (ix) using a 20x20 rectangular grid of rays for the spot rms part of the merit function; (x) making all aspherics and conics variable, except on the objectside surface of the seventh lens; (xi) increasing the f-number to 2; (xii) increasing sampling to 40x40; (xiii) targeting a positive curvature on the image-side surface of lens 6 with the CVGT 0 operand; (xiv) increasing FTGT to 0.2 on lens 7; (xv) increasing the focal length of lens 6 to 3mm; (xvi) targeting a positive curvature on the object side of lens 7 with the CVGT 0 operand; (xvii) reducing the power of lens 7; (xviii) increasing the target focal length on lens 6; (xix) releasing the focal length constraint on lens 7; (xx) releasing the focal length constraints on lenses 5 and 6; (xxi) reducing f-number in steps to 1.65; (xxii) adding DIMX operands; (xxiii) freezing the conics on surfaces 10 and 14; (xxiv) adding FCGT and FCGS commands to limit field curvature; (xxv) adding LONAs into the merit function — thus “resulting” in the Fukaya lens system with a meniscus-gullwing lens pair for lenses 6 and 7.5 Ex. 1001 ¶¶ 82–85. We are not persuaded that this exercise is sufficiently free of hindsight motivation. For purposes of this Decision, we accept that gullwing/meniscus designs were well-known as of the priority date.6 However, the fact that such designs were available and could have been used does not mean that they would have been used.

      “ordinary skill, as of the August 2014 priority date of the ’845 patent, would have been motivated to modify the Fukaya seven-lens system to change the bi-convex/bi-concave design of the sixth and seventh lenses to a double gullwing/meniscus design. Redesigning a lens system is extraordinarily complicated, requiring protracted trial-and-error experimentation with nearly an infinite number of possible solutions in a highly multidimensional space. Ex. 1010, 11; Ex. 1011, 169. We conclude that Petitioner and its expert navigate along one path out of many to the particular redesign they propose using improper result-oriented hindsight as a guide. Petitioner’s expert’s recitation of the at least 25 steps taken to journey from the original Fukaya design to the modified design is instructive: (i) inputting into lens design software the original Fukaya lens parameters; (ii) evaluating its off-axis performance; (iii) increasing the number of analysis field points; (iv) deciding to focus on lenses 5–7, which requires that all aspherics be varied; (v) modifying lens 6 aspherics; (vi) adding CARD operands in the merit function to change the curvature radius values on the lens surfaces; (vii) adding FTGT operands to control spacing between the lenses and lens thicknesses; (viii) adjusting CENY to set the field height; (ix) using a 20x20 rectangular grid of rays for the spot rms part of the merit function; (x) making all aspherics and conics variable, except on the objectside surface of the seventh lens; (xi) increasing the f-number to 2; (xii) increasing sampling to 40x40; (xiii) targeting a positive curvature on the image-side surface of lens 6 with the CVGT 0 operand; (xiv) increasing FTGT to 0.2 on lens 7; (xv) increasing the focal length of lens 6 to 3mm; (xvi) targeting a positive curvature on the object side of lens 7 with the CVGT 0 operand; (xvii) reducing the power of lens 7; (xviii) increasing the target focal length on lens 6; (xix) releasing the focal length constraint on lens 7; (xx) releasing the focal length constraints on lenses 5 and 6; (xxi) reducing f-number in steps to 1.65; (xxii) adding DIMX operands; (xxiii) freezing the conics on surfaces 10 and 14; (xxiv) adding FCGT and FCGS commands to limit field curvature; (xxv) adding LONAs into the merit function — thus “resulting” in the Fukaya lens system with a meniscus-gullwing lens pair for lenses 6 and 7.5 Ex. 1001 ¶¶ 82–85. We are not persuaded that this exercise is sufficiently free of hindsight motivation. For purposes of this Decision, we accept that gullwing/meniscus designs were well-known as of the priority date.6 However, the fact that such designs were available and could have been used does not mean that they would have been used. Belden Inc. v. Berk–Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). We agree with Patent Owner that there is no evidence that that Fukaya was in need of any improvements to its compactness, aberrations, or chief ray angle. Prelim. Resp. 27. As Patent Owner establishes, the original Fukaya track length is actually shorter than the track length of the redesigned lens systems proposed by Petitioner, aberrations are properly corrected in the unmodified Fukaya lens system, and Petitioner’s redesign provides only minimally improved off-axis relative illumination. Id. at 27–33.” slip op. at 23
