Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1, 8, 10, and 17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2020/0043223 A1 to Leiby et al. (Leiby).
As to claim 1, Leiby discloses an electronic device (102) (Fig, 1, Par. 21) comprising: a display panel (Fig. 1, Pars. 21-22, e.g. HMD 100 may include a single display panel, or more than two display panels), configured to update displayed images at a refresh rate (Fig. 1, Pars. 15, 18); and a controller (GPU), coupled to the display panel (Fig. 1, Par. 29); wherein the controller (GPU) is configured to: receive a target frame rate from a first application (Fig. 1, Pars. 15, 18, see also Par. 29); determine a frame rate (e.g. updated/adjusted frame rate) according to the refresh rate (e.g. refresh rate of display) and the target frame rate (e.g. target frame rate of application)(Fig. 1, Pars. 15, 18, see also Par. 29), wherein the frame rate (e.g. updated/adjusted frame rate) is a factor of the refresh rate (Fig. 1, Pars. 15, 18, see also Par. 29); and control the first application to draw images at the frame rate (Fig. 1, Pars. 15, 18, see also Par. 29).
As to claim 10, see claim 1 rejection above.
As to claim 8, Leiby discloses when the target frame rate is lower than the refresh rate and the target frame rate is a factor of the refresh rate (Fig. 1, Pars. 15, 18; i.e. a compositor may throttle the application's frame rate to match the refresh rate of the HMD (e.g., 90 Hz)), the controller is further configured to: determine that the frame rate is the target frame rate (Fig. 1, Pars. 15, 18).
As to claim 17, see claim 8 rejection above.
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) 4 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over US 2020/0043223 A1 to Leiby et al. (Leiby) and US 2014/0368519 A1 to Wood et al. (Wood).
As to claim 4, Leiby does not expressly disclose when the target frame rate is higher than the refresh rate, the controller is further configured to determine that the frame rate is the refresh rate.
Wood discloses when the target frame rate is higher than the refresh rate, the controller is further configured to determine that the frame rate is the refresh rate (Par. 7 and 13, see also Par. 27, if the application is not approved to use the custom refresh rate, then frames presented by the application are displayed at the standard refresh rate notwithstanding whether the frames are presented using the custom refresh rate; e.g. custom refresh rate for paint application 120Hz and refresh display rate 60Hz).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to have modified Leiby with the teaching of Wood to provide a seamless transition between modes in response to events occurring on the computer thereby provide an improved display device as suggested by Wood (Par. 8).
As to claim 13, see claim 4 rejection and motivation above.
Claims 9 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over US 2020/0043223 A1 to Leiby et al. (Leiby) and US 2007/0206018 A1 to Bajic et al. (Bajic).
As to claim 9, Leiby does not expressly disclose when remaining battery power of the electronic device is lower than a first threshold or temperature of the electronic device is higher than a second threshold, the controller is further configured to control the first application to lower its frame rate.
Bajic discloses when remaining battery power of the electronic device is lower than a first threshold, the controller is further configured to control the first application to lower its frame rate (Pars. 11, 59).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to have modified Leiby with the teaching of Bajic to improve power management as suggested by Bajic (Par. 7).
As to claim 18, see claim 9 rejection and motivation above.
Allowable Subject Matter
Claims 2-3, 5-7, 11-12, and 14-16 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The allowable subject matter is: the controller is further configured to inform the first application that a control parameter is equal to N; wherein the first application is configured to draw an image every N times the first application receives the vsync signal; wherein N is the refresh rate divided by the frame rate of claims 2 and 11, respectively, including all of the limitations of the base claim and any intervening claims.
The allowable subject matter is: the controller is further configured to generate a control signal every N times the vsync signal is generated, wherein N is the refresh rate divided by the frame rate; wherein the first application is configured to draw an image every time the first application receives the control signal of claims 3 and 12, respectively, including all of the limitations of the base claim and any intervening claims.
The allowable subject matter is: when the target frame rate is lower than the refresh rate and the target frame rate is not a factor of the refresh rate, and when a first window of the first application displayed on the display panel is smaller than a second window of a second application displayed on the display panel, the controller is further configured to determine that the frame rate is a number that is lower than the target frame rate and is a factor of the refresh rate of claims 5 and 14, respectively, including all of the limitations of the base claim and any intervening claims.
The allowable subject matter is: when the target frame rate is lower than the refresh rate and the target frame rate is not a factor of the refresh rate, and when a first window of the first application displayed on the display panel is larger than a second window of a second application displayed on the display panel, the controller is further configured to determine that the frame rate is the target frame rate and to control the display panel to adjust the refresh rate to the target frame rate. of claims 7 and 16, respectively, including all of the limitations of the base claim and any intervening claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure:
US 2021/0065658 A1 to Ji et al teaches a method for controlling refresh rate of a screen configured to set the picture frame rate of an interface of an application that supports reading and browsing to be more than or lower than the maximum frame refresh rate on the reading and browsing scene.
