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) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 20160013252 (Wang) in view of US 20090195144 (Kitabayashi). Concerning claim 1, Wang discloses a pixel structure (Figs. 4, 5, and 8), PNG media_image1.png 323 323 media_image1.png Greyscale comprising a plurality of sub-pixels (21), wherein an anode (6) of each of the plurality of sub-pixels is configured to be connected to a pixel driver circuit, and each of sub-pixels of at least one color in the plurality of sub-pixels comprises four target sub-pixels (Fig. 4, [0039]), wherein the four target sub-pixels have anodes connected with each other ([0050]); and wherein the four target sub-pixels of a same sub-pixel are separated . . . by a first separation region (8) extending along a first direction and a second separation region (8) extending along a second direction perpendicular to the first direction ([0056], note that the bank structures are formed in a crisscross configuration and the examiner is interpreting the vertical portions of the banks are considered the first separation region and the horizontal portions of the banks are considered the second separation region), wherein at least a part of a side of the first separation region and at least a part of another side of the first separation region are facing each other, parallel to each other and spaced from each other by an interval of a first width ([0054]), at least a part of a side of the second separation region and at least a part of another side of the second separation region are facing each other, parallel to each other and spaced from each other by an interval of a second width, and each of the first width and the second width is smaller than an interval between adjacent sub-pixels in the plurality of sub-pixels ([0056]-[0057]), and wherein each of the plurality of sub-pixels comprises a cathode (7) and an organic functional layer between the anode and the cathode ([0058]);. Wang does not disclose wherein the four target sub-pixels of a same sub-pixel are separated from on another by a first separation region extending along a first direction and a second direction region extending along a second direction perpendicular to the first direction . . . and the four target sub-pixel of a same sub-pixel share a same anode and are driven by a same pixel driver circuit, and within in a same sub-pixel, the first separation region and the second separation region divided the organic functional layer into four independent light emitting regions, such that the sub-pixel is divided into four target sub-pixels. However, Kitabayashi discloses a light emitting device configuration (Figs. 3 and 4) wherein a plurality of sub-pixel regions (region 341 is divided into four regions Fig. 3) are separated into four target sub-pixels of a same sub-pixel from on another by a first separation region extending along a first direction and a second direction region extending along a second direction perpendicular to the first direction((342) Figs. 3 and 4, [0090] note that electrode separating layer separates the pixel electrode into 4 portions) and the four target sub-pixel of a same sub-pixel share a same anode (Fig. 4) and are driven by a same pixel driver circuit ([0074]). Kitabayashi also discloses that each of the plurality of sub-pixels comprises a cathode (5) and an organic functional layer (18) between the anode and the cathode ([0083] and [0091]); and within in a same sub-pixel, the first separation region and the second separation region divided the organic functional layer into four independent light emitting regions, such that the sub-pixel is divided into four target sub-pixels ([0098], it is noted that the electrode separating layer 342 may be formed to have a thickness for separating the entire light emitting function layer thus separating the light emitting layer into 4 subpixels as seen in Fig. 3). Such configuration is disclosed to provide a light emitting device and an electronic apparatus capable of implementing high definition and easiness in manufacture that are incompatible with each other ([0010]).Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention of Wang such that the four target sub-pixels of a same sub-pixel are separated from on another by a first separation region extending along a first direction and a second direction region extending along a second direction perpendicular to the first direction with the four target sub-pixel of a same sub-pixel share a same anode and are driven by a same pixel driver circuit and each of the plurality of sub-pixels comprises a cathode and an organic functional layer between the anode and the cathode; and within in a same sub-pixel, the first separation region and the second separation region divided the organic functional layer into four independent light emitting regions, such that the sub-pixel is divided into four target sub-pixels as disclosed by Kitabayashi in order to provide a light emitting device and an electronic apparatus capable of implementing high definition and easiness in manufacture that are incompatible with each other.
