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) 4 and 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shigee (JP 2015177151). Claim 4: Shigee teaches the set soldering shape comprises the second notch (notch of 202b, fig. 1) formed on the first side surface (side surface of 222, fig. 1). However, Shigee is silent about the first notch is in communication with the second notch. It would have been an obvious matter of design choice to change the shape of the first notch be in communication with the second notch to improve soldering connection, since it has been held that the configuration of the first and second notch was a matter of choice which a person of ordinary skill in the art would have found obvious absent persuasive evidence that the particular configuration of the claimed invention was significant. In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966). Claim 13: Shigee fails to teach a maximum transverse width Wi of an upper end of at least one of the metal pads close to the upper surface is greater than or equal to a maximum transverse width W2 of the region of the first side surface of the metal pad exposed from the support housing; and/or a maximum transverse width W4 of a region of the lower surface of at least one of the metal pads exposed from the support housing is greater than or equal to the maximum transverse width W2 of the region of the first side surface of the metal pad exposed from the support housing. It would have been an obvious matter of design choice to change the dimensions of the metal pads where a maximum transverse width Wi of an upper end of at least one of the metal pads close to the upper surface is greater than or equal to a maximum transverse width W2 of the region of the first side surface of the metal pad exposed from the support housing; and/or a maximum transverse width W4 of a region of the lower surface of at least one of the metal pads exposed from the support housing is greater than or equal to the maximum transverse width W2 of the region of the first side surface of the metal pad exposed from the support housing to enhance electrical connection, since it has been held that where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. In re Rose, 220 F.2d 459, 105 USPQ 237 (CCPA 1955). Claim(s) 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shigee (JP 2015177151) in view of Shen (US 2020/0292149). Claim 19: Shigee teaches the first side surface (side surface of 222) is coplanar with the support housing (see fig. 1) or the lower surface is coplanar with the support housing (see fig. 1). However, Shigee fails to teach the LED lamp bead is a side emitting LED lamp bead, or the LED lamp bead is a front emitting LED lamp bead. Shen teaches a LED lamp bead is a front emitting LED lamp bead (see fig. 1A). Therefore, in view of Shen, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to substitute the LED lamp bead die of Shigee with the front emitting LED lamp bead of Shen, in order to provide a top light emitting surface LED. Claim 20: Shigee teaches a substrate (8, fig. 1) and a LED lamp bead (4, fig. 1) according to claim 16, wherein the LED lamp bead (4) are electrically connected to the substrate (8). However, Shigee fails to teach a plurality of LED lamp beads. Shen teaches a plurality of LED lamp beads (106, fig. 1H). Therefore, in view of Shen, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to add a plurality of LED lamp beads, that are electrically connected to the substrate in order to increase the brightness of the light-emitting module. Furthermore, it would have been obvious to one having ordinary skill in the art at the time the invention was made to add additional LED lamp beads to increase the total brightness, since it has been held that mere duplication of the essential working part of a device involves only routine skill in the art. St. Regis Paper Co. v. Bemis Co., 193 USPQ 8.
