Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.

the plurality of sub-pixels include a first sub-pixel, a second sub-pixel and a third sub-pixel;(fig. 3a-3c 121a, 121b, etc for each R, G, and B))
[0086] For example, as shown in FIGS. 3B and 3C, a pixel circuit 121a of the first sub-pixel G1 further includes a first parasitic circuit 125a, and a pixel circuit 121b of the second sub-pixel G2 further includes a second parasitic circuit 125b. For example, the first parasitic circuit 125a is electrically connected to a control terminal of a drive circuit 122a of the pixel circuit 121a of the first sub-pixel G1 and a first light-emitting voltage application electrode of a light-emitting element 120a of the first sub-pixel G1, and is configured to control a voltage of the control terminal of the drive circuit 122a of the pixel circuit 121a of the first sub-pixel G1 based on a voltage of the first light-emitting voltage application electrode of the light-emitting element 120a of the first sub-pixel G1. The second parasitic circuit 125b is electrically connected to a control terminal of a drive circuit of a pixel circuit 121b of the second sub-pixel G2 and a first light-emitting voltage application electrode of a light-emitting element 120b of the second sub-pixel G2, and is configured to control a voltage of the control terminal of the drive circuit 122b of the pixel circuit 121b of the second sub-pixel G2 based on a voltage of the first light-emitting voltage application electrode of the light-emitting element 120b of the second sub-pixel G2.

Liu fails to teach an orthographic projection of at least one of a first reset transistor of the second sub-pixel or a first reset transistor of the third sub-pixel on the substrate is located within an orthographic projection of the light-emitting device of the first sub-pixel on the substrate.
Examiner notes Liu teaches:
[0136] For example, as shown in FIG. 6C, an orthographic projection of the first light-emitting voltage application electrode 1201a of the light-emitting element of the first sub-pixel G1 on the base substrate 10 at least partially overlaps with an orthographic projection of a control terminal 1221a of the drive circuit of the pixel circuit of the first sub-pixel G1 on the base substrate 10, and an orthographic projection of the first light-emitting voltage application electrode 1201b of the light-emitting element of the second sub-pixel G2 on the base substrate 10 at least partially overlaps with an orthographic projection of a control terminal 1221b of the drive circuit of the pixel circuit of the second sub-pixel G2 on the base substrate 10.
Examiner notes Liu fails to teach the cited portions because the reset transistor is not shared amongst the sub-pixels which examiner understand to be the inventive concept.
However, Chen teaches an orthographic projection of at least one of a first reset transistor of the second sub-pixel or a first reset transistor of the third sub-pixel on the substrate is located within an orthographic projection of the light-emitting device of the first sub-pixel on the substrate.[0067] (fig. 7a (744))(fig. 8a 540 and 716)). Examiner notes 780a sub-pixel with an orthographic projection over 744.

Embodiments relate to a display device with subpixels that share switch transistors that selectively connect sources of driving transistors to a high voltage source. Further, part of reset transistors or part of a select transistor may be shared across multiple subpixels. The reset transistor selectively connects an anode of an organic light emitting diode (OLED) to a low voltage source. The select transistor selectively passes through pixel data from a data line when a gate signal is received via a gate line. Driver transistors and capacitors of the subpixels are independent and not shared. In this way, the dimensions of the subpixels may be reduced and enable increase in the density of the pixels.(abstract)

In regards to claim 3, Liu in view of Chen teaches display panel according to claim 1, wherein at least two of the first reset transistor of the first sub-pixel, the first reset transistor of the second sub-pixel, and the first reset transistor of the third sub-pixel are a same transistor (fig. 7a same transistor 742 and 744 shared amongst 4 sub-pixels Chen).
