Regrading claim 14. SHIMA further discloses the control switch is further configured to activate only the second LEDs in the second lighting zone (see Para. 0078). 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. Claims 4-6 and 11-13 are rejected under 35 U.S.C. 103 as being unpatentable over Lu in view Hsieh et al. (US 12,467,611 hereinafter refer as “Hsieh”). Regrading claims 4 and 11. Lu further discloses an outer housing (1, see Fig. 1, Para. 0122) including a lamp cover (see Fig. 1). However, Lu is silent with respect to the outer housing including a lamp base, wherein the lamp base is provided with a receiving chamber for accommodating the LED panel, and the lamp cover is coupled with the lamp base to enclose the receiving chamber, the LED panel, and the light diffusion plate. Hsieh teaches lighting module (200) that includes a lamp housing structure (310 and 230, see Figs. 2 and 3) including a lamp cover (230) and a lamp base (310), wherein the lamp base is provided with a receiving chamber for accommodating an LED panel (210), and the lamp cover is coupled with the lamp base to enclose the receiving chamber, the LED panel, and a light diffusion plate (220, see Figs. 2 and 3, see Col. 4; lines 51-67). Therefore, in view of Hsieh, it would have been obvious for a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lu by incorporating the lamp base disclosed by Hsieh for the purpose of effectively enclosing the LED panel and the light diffusion plate as suggested by Hsieh, since it has been held by the courts that combining prior art elements according to known methods to yield predictable results, simple substitution of one known element for another to obtain predictable results, or choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success, is not sufficient to distinguish over the prior art, as it requires only ordinary skill in the art. KSR International Co. v. Teleflex Inc., 82 USPQ2d 1385, 1397 (2007). In this case, providing a lamp base configured to accommodate the LED panel and the light diffusion plate would have flown naturally to one of ordinary skill in the art as necessitated by the specific requirements of a given application. Regrading claims 5 and 12. Lu further discloses the lamp cover (1, see Fig. 1, Para. 0122) includes a peripheral sidewall, the sidewall being transparent or semi-transparent (i.e. the lamp cover is used for homogenizing and mixing the emitted light, preventing the light from being too glaring). Lu further discloses diffusers are typically made from materials like frosted glass or plastic, which scatter light as it passes through (see Para. 0017). However, Lu is silent with respect to the central region of the lamp cover being frosted. It would have been obvious for a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lu by forming the central region of the lamp cover to be frosted in order to scatter light as it passes through, since it has been held by the courts that choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success, is not sufficient to distinguish over the prior art, as it requires only ordinary skill in the art. KSR International Co. v. Teleflex Inc., 82 USPQ2d 1385, 1397 (2007). In this case, forming the central region of the lamp cover to be frosted would have flown naturally to one of ordinary skill in the art as necessitated by the specific requirements of a given application. Regrading claims 6 and 13. The teachings of Lu have been discussed above. However, Lu is silent with respect to the lamp housing is installable on a ceiling fan. Hsieh further teaches lighting module (200) is installable on a ceiling fan (see Figs. 1 and 2, Col. 4; lines 41-67). Therefore, in view of Hsieh, it would have been obvious for a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lu by incorporating a lamp housing configured to be installable in a fan, as disclosed by Hsieh in order to provide a ceiling fan lamp, since it has been held by the courts that combining prior art elements according to known methods to yield predictable results, is not sufficient to distinguish over the prior art, as it requires only ordinary skill in the art. KSR International Co. v. Teleflex Inc., 82 USPQ2d 1385, 1397 (2007). In this case, incorporating the lamp housing configure for installation in a fan would have flown naturally to one of ordinary skill in the art as necessitated by the specific requirements of a given application. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Xu et al. (US 12,276,397) discloses an LED lamp includes a lamp holder provided with a mounting groove; an LED lamp panel mounted in the mounting groove and including a plurality of groups of light-emitting elements uniformly arranged in a plurality of sectors; Liang et al. (US 10,948,168) discloses a downlight apparatus includes a container housing, a light source module, and a lens module; and JUNG et al. (US 2017/0082262) discloses a lighting apparatus including: a base; a first light emitting device (LED) array disposed on the base; a second LED array disposed on the base; and an optical device disposed on the base, the optical device including: a first lens covering the first LED array; and a second lens covering the second LED array, wherein a first beam angle of the first lens is different from a second beam angle of the second lens.
