Office Action

§103 §112
DETAILED ACTION 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 § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 5, 21-22, 27 and 29 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 5, 21, 27 and 29 recite “the preset button” lacks antecedent basis. Claim 22 recite “the child lock ON/OFF control in the mobile client” lack antecedent basis. 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. Claims 1, 6, 17, 19-20, 22 and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Case US 20220151450 A1 in view of Alexander US 20170042373 A1. Regarding claim 1, Case teaches a child lock control method, applied to a robot comprising at least one button (Fig. 4B & 6A [0147] a mobile robot with physical button to initiate a cleaning mission and a mobile device with user interface for robot control), and comprising: receiving a child lock activation instruction; and turning off a button response corresponding to the at least one button according to the child lock activation instruction ([0170] receiving instruction from mobile device UI to disable the physical button “a child lock activation instruction” to prevent initiating a cleaning mission; the recited “child lock” is merely an intended use for the lock function that does not bear the weight of patentability). Case does not explicitly further teach: the child lock activation instruction is received when the robot is in a charging state. Alexander explicitly teaches in an analogous art: the child lock activation instruction is received when the robot is in a charging state (Fig. 22 [0358] [0371] – [0373] the plates are placed on charging location for charging, the limited function switches can be actuated to disable one or more operation modes of the plate, via communication for instructions from the charging station to the plates, i.e. “receiving a child lock activation instruction when the robot is in a charging state”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein the child lock activation instruction is received when the robot is in a charging state. One of ordinary skill in the art would have been motivated to do this modification so as to prevent child to operate the undesired function, as Alexander teaches in [0373]. Regarding claim 6, Alexander further teaches after the child lock is activated, in response to a press operation on the at least one button, playing a warning voice indicating that the press operation is invalid ([0373] an indication of child lock mode is sent when the disabled key is pressed, [0367] the indication can be audible sound). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein after the child lock is activated, in response to a press operation on the at least one button, playing a warning voice indicating that the press operation is invalid. One of ordinary skill in the art would have been motivated to do this modification so as to inform the user the child lock is activated, as Alexander teaches in [0373]. Regarding claim 17, it is directed to a robot of carrying out the method with similar limitations as set forth in claim 1. Since Case and Alexander teach the claimed method, they teach the method steps for implementing the robot. In addition, Case further teaches: a robot, comprising an electronic device, wherein the electronic device comprises: one or more processors; and a storage apparatus, configured to store one or more programs, wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to implement a child lock control method (Fig. 3 [0135] the processor and memory storage element of the electronic circuit of the mobile robot). Regarding claim 19, it is directed to an electronic device of carrying out the robot with similar limitations as set forth in claim 17. Since Case and Alexander teach the claimed robot, they teach the electronic device for implementing the robot. Regarding claims 20 and 28, Alexander further teaches: if the child lock ON/OFF control in the mobile client is in an ON state, receiving the child lock deactivation instruction sent by the mobile client ([0352] [0374] the child lock mode can be turned on/off using buttons of remote control); in response to a first press operation on a preset button, determining a first press duration corresponding to the first press operation; determining the child lock activation instruction corresponding to the first press operation if the first press duration is greater than a duration threshold ([0374] pushing and holding predetermined buttons for a period of time to disable child lock mode). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method/device wherein if the child lock ON/OFF control in the mobile client is in an ON state, receiving the child lock deactivation instruction sent by the mobile client; in response to a first press operation on a preset button, determining a first press duration corresponding to the first press operation; determining the child lock activation instruction corresponding to the first press operation if the first press duration is greater than a duration threshold. One of ordinary skill in the art would have been motivated to do this modification so as to disable the child lock mode, as Alexander teaches in [0373]. Regarding claim 22, Alexander further teaches if the child lock ON/OFF control in the mobile client is in an OFF state, receiving the child lock deactivation instruction sent by the mobile client ([0352] [0374] the child lock mode can be turned on/off using buttons of remote control). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein if the child lock ON/OFF control in the mobile client is in an OFF state, receiving the child lock deactivation instruction sent by the mobile client. One of ordinary skill in the art would have been motivated to do this modification so as to disable the child lock mode, as Alexander teaches in [0373]. Claims 2-5, 23-27 and 30-31 are rejected under 35 U.S.C. 103 as being unpatentable over Case in view of Alexander as applied to claims 1, 6, 17, 19-20, 22 and 28, further in view of QIU US 20210401044 A1. Regarding to claim 2, neither Case nor Alexander explicitly further teaches acquiring first voice information; receiving the child lock activation instruction when the first voice information comprises first preset voice information. QIU explicitly teaches in an analogous art that acquiring first voice information; receiving the child lock activation instruction when the first voice information comprises first preset voice information ([0312] [0313] [0318] user speaks a preset voice command for instructing the device to stand by child lock state). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of QIU, because they all directed to child lock control, to make the method wherein acquiring first voice information; receiving the child lock activation instruction when the first voice information comprises first preset voice information. One of ordinary skill in the art would have been motivated to do this modification so as to trigger the lock mode, as QIU teaches in [0318]. Regarding claim 3, Alexander further teaches receiving a child lock deactivation instruction after the child lock is activated; and turning on the button response corresponding to the at least one button according to the child lock deactivation instruction ([0373] disable child lock mode on plate by entering unlock combination button-sequence). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein receiving a child lock deactivation instruction after the child lock is activated; and turning on the button response corresponding to the at least one button according to the child lock deactivation instruction. One of ordinary skill in the art would have been motivated to do this modification so as to let the user to control the operation, as Alexander teaches in [0373]. Regarding claim 4, QIU further teaches acquiring second voice information; receiving the child lock deactivation instruction when the second voice information comprises second preset voice information ([0290] preset voice command for waking up device from standby state). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of QIU, because they all directed to child lock control, to make the method wherein acquiring second voice information; receiving the child lock deactivation instruction when the second voice information comprises second preset voice information. One of ordinary skill in the art would have been motivated to do this modification so as to disable the lock mode, as QIU teaches in [0290]. Regarding claim 5, Alexander further teaches after the child lock is activated, in response to a second press operation on the preset button, determining a second press duration corresponding to the second press operation; determining the child lock deactivation instruction corresponding to the second press operation if the second press duration is greater than the duration threshold; turning on button responses corresponding to buttons other than the preset button according to the child lock deactivation instruction ([0374] pushing and holding predetermined buttons for a period of time to disable child lock mode). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein after the child lock is activated, in response to a second press operation on the preset button, determining a second press duration corresponding to the second press operation; determining the child lock deactivation instruction corresponding to the second press operation if the second press duration is greater than the duration threshold; turning on button responses corresponding to buttons other than the preset button according to the child lock deactivation instruction. One of ordinary skill in the art would have been motivated to do this modification so as to let the user to control the operation, as Alexander teaches in [0373]. Regarding claim 23, Alexander further teaches the robot comprises a reset button, and the receiving the child lock deactivation instruction comprises: receiving the child lock deactivation instruction in response to a press operation on the reset button ([0374] pushing and holding predetermined buttons for a period of time to disable child lock mode). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of Alexander, because they all directed to child lock control, to make the method wherein the robot comprises a reset button, and the receiving the child lock deactivation instruction comprises: receiving the child lock deactivation instruction in response to a press operation on the reset button. One of ordinary skill in the art would have been motivated to do this modification so as to let the user to control the operation, as Alexander teaches in [0373]. Claims 24-27 recite similar limitations to that of claims 2-5, respectively, therefore are rejected on the same basis, respectively. Claims 30-31 recite similar limitations to that of claims 22-23, respectively, therefore are rejected on the same basis, respectively. Claims 21 and 29 are rejected under 35 U.S.C. 103 as being unpatentable over Case in view of Alexander as applied to claims 1, 6, 17, 19-20, 22 and 28, further in view of Ha US 20140197934 A1. Regarding claims 21 and 29, neither Case nor Alexander explicitly further teaches turning off button responses corresponding to buttons other than the preset button according to the child lock activation instruction. Ha explicitly teaches in an analogous art that turning off button responses corresponding to buttons other than the preset button according to the child lock activation instruction (Fig. 11 [0278] child lock inactivating all input means except a power button). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Case and Alexander to incorporate the teachings of Ha, because they all directed to child lock control, to make the method/device wherein turning off button responses corresponding to buttons other than the preset button according to the child lock activation instruction. One of ordinary skill in the art would have been motivated to do this modification so as to prevent the buttons to trigger operations, as Ha teaches in [0278]. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. CAO CN 207656712 U teaches cleaning robot with child lock; Cato US 20080059880 A1 teaches making child lock mode available or unavailable.
