Response to Arguments
Applicant’s arguments, see pages 7-11, filed 01/30/2026, have been fully considered and are persuasive. In the light of the arguments and the amendment filed on 01/30/2026, the previous rejections have been withdrawn. However, upon further consideration, new grounds of rejection are presented below.
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.
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.
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.
Claims 1, 4-6 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over US 2012/0275115 to Chen (hereinafter “Chen”) in view of CN110454906 to Shan et al. (hereinafter “Shan”, presented in the IDS filed on 12/22/2023, see attached English translation).
Regarding claim 1, Chen teaches an electronic device control method comprising the steps of selecting a target mode from optional modes of a fan (first fan and second fan) of an electronic device, the optional modes comprising a cleaning mode (the fan of the electronic device rotates in reverse), and a heat dissipation mode (the fan of the electronic device rotates forward) [0020, and 0029-0031], generating a control signal based on the target mode [0029], and controlling, based on the control signal, the fan to provide an air strength [0030]. Chen further teaches that when the user uses the electronic device in a normal operation mode, the first fan and the second fan can be adjusted to the low rotation speed, so as to reduce the noise of the fans of the electronic device, and that if the user has a demand in performance (for example, over clocking), the first fan and the second fan can be adjusted to the high rotation speed to increase the heat dissipating efficiency (reads on the limitation “in the heat dissipation mode, the fan provides a single air strength when a heat dissipation level is not switched”) [0030].
Chen does not teach that in the cleaning mode (the fan of the electronic device rotates in reverse), the fan automatically and repeatedly switches between at least two air strengths.
Shan teaches a dust removal method for reducing dust accumulation on the surface of the outdoor heat exchanger, comprising the step of controlling the air conditioner to enter in a dust removal mode (cleaning mode) controlling all fans in the outdoor heat exchanger to run in reverse to remove dust from the outdoor heat exchanger (English translation [0007 and 0009]). Shan further teaches that in the dust removal mode (cleaning mode) the fans can automatically and repeatedly switch between at least two fan speed (e.g., 900rpm and 1200rpm) (reads on “air strength”) (English translation [0085-0092]).
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 method disclosed by Chen wherein in the cleaning mode (the fan of the electronic device rotates in reverse), the fan automatically and repeatedly switches between at least two air strengths, with a reasonable expectation of success, since Shan teaches that it is effective to rotate the fans in reverse at different speeds, wherein the fans can be automatically and repeatedly switched between at least two air strengths to overcome the problem of poor dust removal (English translation [0073, and 0085-0092] of Shan).
Regarding claim 4, Chen/Shan further teaches that selecting the target mode from optional modes of the fan of the electronic device comprises the step of selecting the cleaning mode as the target mode at a cleaning time, and selecting the heat dissipation mode as the target mode at a time other than the cleaning time ([0028] of Chen).
Regarding claims 5 and 6, Chen/Shan further teaches the steps of determining a cleaning delay, and determining the cleaning time based on the cleaning delay after the electronic device is powered on ([0028] of Chen).
Regarding claim 8, Chen further teaches that running status information comprises temperature status information indicating an internal temperature status of the electronic device ([0032] of Chen).
However, Chen/Shan does not explicitly teach the step of determining, based on the temperature status information, the time at which a temperature value of the powered-on electronic device is lower than a preset temperature value as the cleaning time.
However, 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 method disclosed by Chen/Shan with the step of determining, based on the temperature status information, the time at which a temperature value of the powered-on electronic device is lower than a preset temperature value as the cleaning time, with a reasonable expectation of success, since Chen teaches the step of monitoring the temperature in the casing of the electronic device, and that when the temperature in the casing of the electronic device is greater than a predetermined value, the basic input output system can confine the first fan and the second fan to only be able to rotate forward, so as to avoid a situation that the first fan and the second fan rotate in reverse to reduce the heat dissipating performance of the system that could cause damage of the components or compulsory shut-down of the electronic device ([0032] of Chen).
Claims 2-3 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over US 2012/0275115 to Chen (hereinafter “Chen”) in view of CN110454906 to Shan et al.
