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 (i.e., changing from AIA to pre-AIA ) 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, 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) 1-6 and 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ma et al. (US 20210306612 A1) in view of Sun et al. (US 20210400253 A1) and Park (US 20220377916 A1).
Regarding claim 1, Ma teaches a three-dimensional display device (figs. 9 and 10), comprising:
a base (4 of fig. 9, [0099 and 0101]);
a rotating table (5 and 6 of fig. 9, [0099, 0101, and 0102]), rotatably connected to the base; and
at least one display panel disposed on the rotating table (8 and 9 of fig. 9, [0102]);
a circuit assembly (5-7 of fig. 9),
wherein the rotating table (6 of fig. 9) has an upper surface and a lower surface opposite to each other,
the at least one transparent display panel is disposed on the upper surface (9 of fig. 9),
the circuit assembly is disposed on the lower surface (5 of fig. 9), and
the circuit assembly is located between the base (4 of fig. 9) and the at least one transparent display panel (9 of fig. 9; [0087], [0099] to [0102]);
wherein the circuit assembly comprises at least one driving circuit board (5 of fig. 9, [0087]).
It is noted that Ma is silent about at least one transparent double-sided display panel having a first display surface and a second display surface opposite to each other.
Sun teaches at least one transparent double-sided display panel having a first display surface and a second display surface opposite to each other (5, 501, 502, and 503 of fig. 2, [0025-0026]).
Taking the teachings of Ma and Sun together as a whole, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the transparent display of Sun into the display of Sun to provide the side surface is configured as a display surface, the number of voxels generated by the display assembly may be significantly increased, promoting an improvement of the display effect ([0031] of Sun).
It is further noted that Ma and Sun do not teach as each of the at least one driving circuit board approaches the rotation axis, a width of a board body of the driving circuit board correspondingly decreases as shown in figure below.

Yokota teaches a plurality of ball bearings, wherein the base comprises a plurality of bearing fixing portions, the ball bearings are respectively disposed on the corresponding bearing fixing portions, and the ball bearings are connected between the base and the rotating table ([0052]).
Taking the teachings of Ma, Sun, Park, and Yokota together as a whole, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the bearing balls of Yokota into the base and the rotating table Ma in view of Sun and Park to easily rotate the display panel in 360 degrees.
Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ma et al. (US 20210306612 A1) in view of Sun et al. (US 20210400253 A1) and Park (US 20220377916 A1) as applied to claim 1, and further in view of Rotzoll et al. (US 20190027534 A1).
Regarding claim 9, Ma, Sun, and Park teach the three-dimensional display device according to claim 1, but Ma, Sun, and Park do not teach wherein each of the at least one transparent double-sided display panel has a plurality of through holes.
Rotzoll teaches wherein each of the at least one transparent double-sided display panel has a plurality of through holes (30 and 99 of fig. 1, [0052] and [0058] According to some embodiments of the present invention, air can flow through holes 30 in a display substrate 10 to cool micro-iLEDs 22. Holes 30 in an iLED display 99 can improve utilization of various cooling schemes for the associated viewing space as well as the iLED display 99. For example, forcing air in either direction through a display substrate 10 from the rear (a side of the display substrate 10 opposite a viewer of the iLED display 99) would improve cooling of display-related components behind the iLED display 99. Holes 30 can also be used to allow at least some of the air in a room to flow through an iLED display 99, thereby reducing the iLED display 99 impact on existing air conditioning and heating systems in a given room in which the iLED display 99 is placed).
Taking the teachings of Ma, Sun, Park, and Rotzoll together as a whole, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the display with holes of Rotzoll into the first side and second side of the combined display of Ma in view of Sun and Park for air passing through the holes that would prevent the decreasing rotation of the display.
Response to Arguments
Applicant's arguments filed 05/04/2026 have been fully considered but they are not persuasive.
The applicant argues that Park does not teach that the second panels 410, 420 and 430 are used as driving PCBs. Therefore, Park, in combination with Ma and Sun, fails to teach or suggest the limitation of "as each of the at least one driving circuit board approaches the rotation axis, a width of a board body of the driving circuit board correspondingly decreases" as recited in claim 1 in the remarks.
The examiner strongly disagrees with the applicant. It is submitted that the second panels, 410, 420 and 430 of fig. 10, are used as driving PCBs, [0085] the first panel 310 of the first light source module 300 as an example, and the same may apply to the other panels 320 and 330. Further, the same may apply to the second panels 410, 420, and 430 of the second light source module 400; the second panels 410, 420, and 430 of the second light source module 400 may also have the same structure as shown in FIGS. 4 and 5; [0086] the panel 310 may be a printed circuit board (PCB), the same may apply to the second light panels 410, 420, and 430; [0088] FIG. 5 illustrates the rear surface of the panel 310. Drivers 314 for driving the light-emitting elements 312 may be mounted on the rear surface of the panel 310, which constitutes the light source module; [0089] since the drivers 314 are mounted on the rear surface of the panel 310. This disclosure teaches the driving circuit, 314 of fig. 5, attached to the printed circuit board, 310 of fig. 5, to form the driving circuit board. The same apply to the second panels 410, 420, and 430 as suggested in paragraph [0085].
Park further teaches as each of the at least one driving circuit board approaches the rotation axis (410, 420, and 430 of fig. 4, illustrating the second panel has one end that approaches to the rotation axis), and a width of a board body of the driving circuit board correspondingly decreases (410, 420, and 430 of fig. 10, the second panel has a width decreases at the end at the rotation axis, C’of figure 10).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Lu (US 20240036340 A1) discloses a screen for unidirectional beam homogenizing and expanding, which is arranged to expand, along a first direction, beams of light with different angles of emergence emitted by a projection unit into light cones with uniform intensity and same distribution, with propagation direction and angle of divergence unchanged along a second direction, wherein the screen for unidirectional beam homogenizing and expanding comprises a lenticular grating and at least one linear Fresnel lens.
LV et al. (US 20240221548 A1) The present disclosure provides a display panel, a driving method thereof and a display device, belongs to the field of display technology, and can at least partially solve the problem that the transmission bandwidth required by the conventional rotational display device is large during the display.
