DETAILED ACTION Status of Case The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This Office Action is in response to the claims filed on 8/28/2024. Claims 1-20 are pending. 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, 3, 7-8, 12, 14, 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Wang (EP 2983394 A1) in view of Maeda (USPAN 2014/0130028) and Brendle (USPAN 2005/0022157). Consider claims 1 and 12, Wang discloses an apparatus comprising processing circuitry (see figures 6-7, wherein disclosed is said apparatus), and a corresponding wireless communication device, comprising: transceiver circuitry configured to communicate with a child device; and processing circuitry communicatively coupled to the transceiver circuitry (see figures 6-7, wherein disclosed is said wireless communication device) configured to: process, based on signaling received from a device, a data request (see figure 11 (reproduced below for convenience) and paragraph 94: receiving a RLF report transmitted by a UE); determine whether an active context exists with the device based on data stored in firmware (see paragraph 94: “the first base station may look up whether the above information exists in the context information”); and PNG media_image1.png 492 540 media_image1.png Greyscale Wang does not specifically disclose to determine whether to respond to the data request based on whether the active context exists. Maeda discloses to determine whether to respond to the data request based on whether the active context exists (see paragraphs 147-156: determining whether or not it is necessary to send an update notification based on the contents thus stored in firmware). 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 invention of Wang and combine it with the noted teachings of Maeda. The motivation to combine these references is to provide a method for remote update of firmware that is mounted in an information processing apparatus (see paragraph 2 of Maeda). Wang does not specifically disclose signaling received by a parent device from a child device. Brendle discloses signaling received by a parent device from a child device (see paragraph 85: the resource can be a parent and/or child to other resources), and further discloses determining whether an active context exists (see paragraph 85: if a resource request has been received, process 500 continues with determining whether the associated application context process is active). 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 invention of Wang and combine it with the noted teachings of Brendle. The motivation to combine these references is to provide a method for application management and for accessing resources for a context that allows for managing resources and for allow an application to be isolated from contexts of other executing applications (see paragraph 5 of Brendle). Consider claims 3 and 14, Wang does not specifically disclose that the processing circuitry is further configured to refrain from responding to the data request when the active context does not exist with the child device. Maeda discloses that the processing circuitry is further configured to refrain from responding to the data request when the active context does not exist with the child device (see paragraphs 147-156: determining whether or not it is necessary to send an update notification based on the contents thus stored in firmware). 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 invention of Wang and combine it with the noted teachings of Maeda. The motivation to combine these references is to provide a method for remote update of firmware that is mounted in an information processing apparatus (see paragraph 2 of Maeda). Consider claims 7 and 18, Wang discloses data stored in firmware comprises a table (see paragraph 94: “the first base station may look up whether the above information exists in the context information”). Wang does not specifically disclose that the data is in a child device. Brendle discloses data that is in a child device (see paragraph 85: the resource can be a parent and/or child to other resources). 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 invention of Wang and combine it with the noted teachings of Brendle. The motivation to combine these references is to provide a method for application management and for accessing resources for a context that allows for managing resources and for allow an application to be isolated from contexts of other executing applications (see paragraph 5 of Brendle). Consider claims 8 and 19, although Wang discloses to establish the active context with the device (see above), Wang does not specifically disclose to store an indication of the active context in the device. Maeda discloses to store an indication of the active context in the device (see paragraph 149: update the firmware, i.e. store an indication in the firmware of the active context). 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 invention of Wang and combine it with the noted teachings of Maeda. The motivation to combine these references is to provide a method for remote update of firmware that is mounted in an information processing apparatus (see paragraph 2 of Maeda). Wang discloses data stored in firmware comprises a table (see paragraph 94: “the first base station may look up whether the above information exists in the context information”). Wang does not specifically disclose that the data is in a child device. Brendle discloses data that is in a child device (see paragraph 85: the resource can be a parent and/or child to other resources). 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 invention of Wang and combine it with the noted teachings of Brendle. The motivation to combine these references is to provide a method for application management and for accessing resources for a context that allows for managing resources and for allow an application to be isolated from contexts of other executing applications (see paragraph 5 of Brendle). Consider claim 20, Wang discloses a method performed by a device (see figure 11, reproduced below for convenience, wherein disclosed is said method), comprising: processing, based on signaling received from another device, a data request (see figure 11 and paragraph 94: receiving a RLF report transmitted by a UE); determining whether the device has an active context with the another device based on data stored in firmware of the device (see paragraph 94: “the first base station may look up whether the above information exists in the context information”). PNG media_image1.png 492 540 media_image1.png Greyscale Wang does not specifically disclose to determine whether to respond to the data request based on whether the active context exists. Maeda discloses to determine whether to respond to the data request based on whether the active context exists (see paragraphs 147-156: determining whether or not it is necessary to send an update notification based on the contents thus stored in firmware).
