Information Disclosure Statement
3. The information disclosure statement (IDS) submitted was filed along with the mailing date of the application on March 25, 2025. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Double Patenting
4. The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Regarding claim 20, Jee teaches circuitry of claim 15, wherein the switch comprises a multiplexer(multiplexer circuit 416, fig.3, Para-51).
Claim Rejections - 35 USC § 103
10. 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.
11. 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.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
12. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
13. Claims 3, 4, and 8 are rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1)in view of Hsiao et al.(US 2011/0175878 A1)(herein after Hsiao).
Regarding claim 3, Jee is not found to teach expressly the display circuitry of claim 2, wherein the data is generated by a system controller based on an image source being configured to consume a first amount of power.
However, Hsiao teaches a display apparatus, wherein the data is generated by a system controller based on an image source (static image or dynamic image, S301 and S307, fig.3) being configured to consume a first amount of power(Para-48, 50).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee with the teaching of Hsiao to include the feature in order to provide a display apparatus capable of overcoming problem of frame flickering due to brightness variation.
Regarding claim 4, Jee as modified by Hsiao teaches the display circuitry of claim 2, wherein the data is associated with whether an image source is configured to consume a first amount of power or a second amount of power(Para-48, 50, Hsiao) (for motivation, see the rejection of claim 3 above).
Regarding claim 8, Jee as modified by Hsiao teaches the display circuitry of claim 1, wherein the switch is operated between the first state(static image or dynamic image, S301 and S307, fig.3) and the second state(static image or dynamic image, S301 and S307, fig.3, Hsiao) based on an amount of power delivered to an image source(Para-48, 50, Hsiao)(for motivation, see the rejection of claim 3 above).
14. Claim 5 is rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1) in view of Hsiao et al.(US 2011/0175878 A1) and further in view of HUANG et al.(WO 2020/168949 A1) (herein after HUANG).
Regarding claim 5, Jee as modified by Hsiao teaches the display circuitry of claim 4, wherein the second amount of power consumed is greater than the first amount of power(Para-20, Jee) (whenever one of ordinary skill in the art considers first power voltage as second power rail and second power voltage as first power rail) (Para-31, Hsiao),
Nevertheless, Jee as modified by Hsiao is not found to teach the display circuitry, wherein the second power rail is configured to couple to a power management integrated circuit, and wherein the first power rail is configured to couple to a display power supply that bypasses the power management integrated circuit.
However, HUANG teaches a display driving circuitry, wherein
the second power rail is configured to couple to a power management integrated circuit(PMIC, fig.2), and
wherein the first power rail(DDIC) is configured to couple to a display power supply(DDIC) that bypasses the power management integrated circuit(PMIC, fig.2).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee further with the teaching of HUANG to include the feature in order to improve driving ability of the DDIC circuit during normal display mode.
15. Claims 9-10, and 16 are rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1) in view of HUANG et al.(WO 2020/168949 A1)(herein after HUANG).
Regarding claim 9, Jee is not found to teach expressly the display circuitry of claim 1, wherein the switch comprises a multiplexer coupled to a display power supply via the first power rail and coupled to a power management integrated circuit via the second power rail.
However, HUANG teaches a display driving circuitry, wherein the switch(203, fig.2) comprises a multiplexer coupled to a display power supply(DDIC, fig.2) via the first power rail (fgi.2) and coupled to a power management integrated circuit (PMIC, fig.2) via the second power rail.
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee with the teaching of HUANG to include the feature in order to improve driving ability of the DDIC circuit during normal display mode.
Regarding claim 10, Jee as modified by HUANG teaches the display circuitry of claim 9, wherein the multiplexer(MUX 416, fig.3, Jee; 203, fig.2, HUANG) decouples the first power rail (412 or 414, fig.2, Jee) from the display panel(300) while the second power rail(414, or 412, fig.2, Jee) is coupled to the display panel(300)(also fig.2, Para-44, HUANG).
Regarding claim 16, Jee as modified by HUANG teaches the circuitry of claim 15, comprising a system-on-chip(chip-based load switch) configured to write data to the register (memory)(Para-61: data storage area can store data created according to the use of the terminal device) to control the switch to switch between coupling the second input coupled to a power management integrated circuit(PMIC, fig.2) to the output and between coupling the first input coupled to a display power supply(DDIC, fig.2, Para-45, HUANG) to the output(for motivation see the rejection of claim 9 above).
16. Claims 11-13 are rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al.(US 2016/0358526 A1)(herein after Wang) in view of Zheng et al.(US 2018/0061355 A1) (herein after Zheng).
Regarding claim 11, Wang teaches a non-transitory, tangible, computer-readable medium(storage device 1018, fig.10, Para-48), comprising computer-readable instructions that, when executed by one or more processors(processor 1002, fig.10, Para-46), cause an electronic device to:
receive a first signal(802, fig.8, Para-44)from an image source (graphics processing unit GPU, Para-27), a system controller, or both;
operate a switch(switch capacitor regulator fig.2B, Para-35) based on the first signal to switch a power supply rail from a first power rail to a second power rail(Para-41); and
send image data to a first pixel based on receiving power from the second power rail(Para-41, 45),
Nevertheless, Wang is not found to teach expressly the non-transitory, tangible, computer-readable medium, wherein a power consumed in sending the image data when coupled to the second power rail is greater than a power consumed in sending the image data when coupled to the first power rail.
However, Zheng teaches content dependent common voltage driver systems, wherein a power consumed in sending the image data when coupled to the second power rail is greater than a power consumed in sending the image data when coupled to the first power rail(positive high voltage rail, negative high voltage rail, positive high voltage rail, negative low voltage rail, fig.7, Para-69).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Wang with the teaching of Zheng to include the feature in order to improve displayed image quality of an electronic display with reduced power consumption.
Regarding claim 12, Wang as modified by Zheng teaches the non-transitory, tangible, computer-readable medium of claim 11, comprising computer-readable instructions that, when executed by the one or more processors, cause the electronic device to operate the switch to decouple from at least a portion of the first power rail and couple to at least a portion of the second power rail(fig.7, Para-69, 70, Zheng; Para-26, Wang).
Regarding claim 13, Wang as modified by Zheng teaches the non-transitory, tangible, computer-readable medium of claim 11, wherein operating the switch to switch changes a power supply of a display panel coupled to the power supply rail (fig.7, Zheng).
17. Claim 14 is rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al.(US 2016/0358526 A1) in view of Zheng et al.(US 2018/0061355 A1) and further in view of KANG et al.(US 2022/0051599 A1) (herein after KANG).
Regarding claim 14, Wang as modified by Zheng is not found to teach expressly the non-transitory, tangible, computer-readable medium of claim 13, comprising computer-readable instructions that, when executed by the one or more processors, cause the electronic device to operate the switch based on the first signal being associated with a change in a refresh rate of image content.
However, KANG teaches a method and a device for driving display panel, wherein, when executed by the one or more processors, cause the electronic device to operate the switch based on the first signal being associated with a change in a refresh rate of image content(Para-23, 41).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Wang further with the teaching of KANG to include the feature in order to eliminate flicker noise thus improving image quality.
18. Claim 17 is rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1) in view of KANG et al.(US 2022/0051599 A1) (herein after KANG).
Regarding claim 17, Jee is not found to teach expressly the circuitry of claim 15, wherein the register is configured to control the switch based on a refresh rate of a display panel being less than 60 hertz.
However, KANG teaches a method and a device for driving display panel, wherein the register(database unit) is configured to control the switch based on a refresh rate of a display panel being less than 60 hertz(Para-46).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee with the teaching of KANG to include the feature in order to eliminate flicker noise thus improving image quality.
19. Claim 18 is rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1) in view of HUSSAIN et al.(US 2021/0407456 A1) (herein after HUSSAIN).
Regarding claim 18, Jee is not found to teach expressly the circuitry of claim 15, wherein the register is configured to control the switch based on incoming image data corresponding to a prerendered entire image frame update.
However, HUSSAIN teaches a system for accelerated frame transmission, wherein the register(memory 150, fig.1) is configured to control the switch based on incoming image data corresponding to a prerendered entire image frame update(Para-19, 42-43).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee with the teaching of HUSSAIN to include the feature in order to update the image at a display panel based on the received data in an efficient manner.
20. Claim 19 is rejected under 35 are rejected under 35 U.S.C. 103 as being unpatentable over Jee et al.(US 2008/0024480 A1) in view of LEE(US 2019/0311678 A1).
Regarding claim 19, Jee is not found to teach expressly the circuitry of claim 15, wherein the register is configured to control the switch based on incoming image data having a brightness value that meets a condition of a first display brightness value being less than or equal to half of a second display brightness value.
However, LEE teaches a display device and driving method, wherein the register is configured to control the switch based on incoming image data having a brightness value that meets a condition of a first display brightness value being less than or equal to half of a second display brightness value (Para-62, 69-72).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filling date of the claimed invention, to have modified Jee with the teaching of LEE to include the feature in order to enhance visibility corresponding to change in external light and luminance of display mode by driving DC-DC converter such that the visibility of a display image in a high-illuminance environment is increased.
