Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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 of this title, 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. Claims 3 and 7 are rejected under 35 U.S.C. 103 as being obvious over YOSHIDA et al (WO 2021084919 A1, corresponding US 20220252238 A1 will be used as the refence below). Regarding claims 3 and 7, Figure 13 of YOSHIDA does not teach light emitting unit according to claim 1, wherein a distance between the light source and the optical member is 0 mm or more and 2 mm or less. Or The light emitting unit according to claim 5, wherein a distance between the light source and the optical member is 0 mm or more and 2 mm or less. However, it would have been obvious to one having ordinary skill in the art at the time of the invention was made to use the above claimed ranges in order to have an improved device with lower cost since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working range involves only routine skill in the art. In re Aller, 105 USPQ 233. Claims 10 and 16 are rejected under 35 U.S.C. 103 as being obvious over YOSHIDA et al (WO 2021084919 A1, corresponding US 20220252238 A1 will be used as the refence below) in view of SANGA et al (US 20180229491 A1). Regarding claim 10, Figure 13 of YOSHIDA teaches that the lens unit according to claim 9, wherein: the first region (12) comprises any one of a through hole, a first light-transmissive portion, a wavelength conversion portion, or a first light diffusion portion ([0040]) and the second region (21+25a) comprises a light shielding portion ([0056]). YOSHIDA does not teach that the light shielding portion is formed of a white resin containing a light scattering substance. However, SANGA is a pertinent art which teaches a light emitting device, wherein SANGA teaches that a light shielding layer contain white resin with light scattering material (50, Figure 9) in order to extract light efficiently [0063]). Thus, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the lens unit of YOSHIDA with a second region (21+25a) of light shielding portion wherein the light shielding portion is formed of a white resin containing a light scattering substance according to the teaching of SANGA in order to extract light efficiently ([0063] of SANGA) from the light emitting device. Regarding claim 16, YOSHIDA does not teach that the lens unit according to claim 14, wherein: the second region is formed of either a white resin containing a light scattering substance or a black resin containing a light absorbing substance. However, SANGA is a pertinent art which teaches a light emitting device, wherein SANGA teaches that a light shielding layer contain white resin with light scattering material (50, Figure 9) in order to extract light efficiently [0063]). Thus, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the lens unit of YOSHIDA with a second region (21+25a) wherein the second region is formed of either a white resin containing a light scattering substance or a black resin containing a light absorbing substance according to the teaching of SANGA in order to extract light efficiently ([0063] of SANGA) from the light emitting device. Examiner Notes A reference to specific paragraphs, columns, pages, or figures in a cited prior art reference is not limited to preferred embodiments or any specific examples. It is well settled that a prior art reference, in its entirety, must be considered for all that it expressly teaches and fairly suggests to one having ordinary skill in the art. Stated differently, a prior art disclosure reading on a limitation of Applicant's claim cannot be ignored on the ground that other embodiments disclosed were instead cited. Therefore, the Examiner's citation to a specific portion of a single prior art reference is not intended to exclusively dictate, but rather, to demonstrate an exemplary disclosure commensurate with the specific limitations being addressed.
