Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments with respect to claim(s) 1-3 and 5-15 have been considered but are moot in view of reconsideration of applicant’s arguments and further consideration of prior art of record in view of independent claims 1, 13 and 14. After further consideration, Torvinen has been found to teach the limitation of “a bottom surface opposite the top surface and at least one conductive track configured to receive power from an external power source”. Applicant amended claim 1 to include the limitations of cancelled dependent claim 4. A new reference, Sweegers et al. (US 2017/0317251 A1), discloses the limitation which includes, “an air gap between an outer-most surface of the wavelength converting coating and the parabolic collimator”. Claims 13 and 14 are amended similarly and therefore are rejected similarly to claim 1. Claim(s) 1, 13 and 14 are now rejected under 35 U.S.C. 103 as being unpatentable over Torvinen (US 2018/0149321 A1) in view of Reshetin (US 4,962,450), Ruan et al. (US 2017/0365760 A1) and Sweegers et al. (US 2017/0317251 A1),See rejection below. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-3, 6-11, and 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Torvinen (US 2018/0149321 A1) in view of Reshetin (US 4,962,450), Ruan et al.

Torvinen does not explicitly teach a parabolic collimator. PNG media_image1.png 276 286 media_image1.png Greyscale Reshetin teaches a parabolic collimator (figure 10; column 2, lines 45-52) wherein a focus point of the parabolic collimator passes through the cavity (see figure 10 where focal point F passes through the cavity. It would have been obvious to one having ordinary skill in the art at the time of the effective filing date of the invention to modify the lighting device of Torvinen to be a parabolic collimator as taught by Reshetin et al. as an obvious and alternative design choice and way to achieve a desired illumination output. Torvinen does not explicitly teach [the light-emitting element] including a wavelength converting coating oriented towards the at least one opening of [the encapsulating material]. Ruan et al.

Reshetin teaches a parabolic collimator (figure 10; column 2, lines 45-52) wherein a focus point of the parabolic collimator passes through the cavity (see figure 10 where focal point F passes through the cavity. It would have been obvious to one having ordinary skill in the art at the time of the effective filing date of the invention to modify the lighting device of Torvinen to be a parabolic collimator having a focus point of the parabolic collimator passing through the cavity as taught by Reshetin et al. as an obvious and alternative design choice and way to achieve a desired illumination output. Torvinen does not explicitly teach [the light-emitting element] including a wavelength converting coating oriented towards the at least one opening of [the encapsulating material]. Ruan et al.

Sweegers et al. teaches an air gap (air gap 24) between an outer-most surface of the wavelength converting coating (20; figure 4) and the parabolic collimator (18; figure 4). It would have been obvious to one having ordinary skill in the art at the time of the effective filing date of the invention to modify the lighting device of Torvinen to include an air gap between an outer-most surface of the wavelength converting coating and the parabolic collimator as taught by Sweegers et al. as an obvious and alternative design choice and way to achieve a desired illumination output as disclosed in paragraph [0080]-[0081] of Sweegers et al. Regarding claim 15, Torvinen further teaches the automotive lighting system of claim 14, wherein the automotive lighting system is one of a head light, a back light, an interior light, or body light included in the body of a vehicle (see claim 16 and at least figure 2 where the lighting device 20 may be used for an automotive interior light). Claim(s) 5 is rejected under 35 U.S.C. 103 as being unpatentable over Torvinen (US 2018/0149321 A1) in view of Reshetin (US 4,962,450), Ruan et al. (US 2017/0365760 A1) and Sweegers et al.

Regarding claim 5, Torvinen modified by Reshetin, Ruan et al. and Sweegers et al. teaches the lighting device according to claim 1, but does not teach wherein the collimator comprises a flexible material. Labas teaches a lighting device that comprises a flexible material (silicone; see paragraph [0028]; see at least figure 1-2). It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the lighting device of Torvinen to include a flexible material as taught by Labas to easily shape collimator by methods such as extrusion and/or molding and to achieve a highly reflective surface to achieve a desired illumination output (see paragraph [0028]).

Regarding claim 12, Torvinen modified by Reshetin, Ruan et al. and Sweegers et al. teaches the lighting device according to claim 9, but Torvinen modified by Ruan et al. does not explicitly teach wherein at least one of: the wavelength converting coating further comprises reflecting particles, or the light blocking coating further comprises phosphor particles. Deckers et al. further teaches wherein at least one of: the wavelength converting coating further comprises reflecting particles, or the light blocking coating further comprises phosphor particles (see at least figures 2-4; paragraphs [0046]-[0049]). It would have been obvious to one having ordinary skill in the art at the time of the effective filing date of the invention to modify the lighting device of Torvinen to include a wavelength converting material as taught by Deckers et al. as an obvious and alternative design choice and way to achieve a desired illumination output as disclosed in paragraph [0014] of Deckers et al.
