Office Action

§102
DETAILED ACTION Claims 1-9 are pending. 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 . Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Interpretation MPEP 2111.04 (II) states, in part and with emphasis added: The broadest reasonable interpretation of a method (or process) claim having contingent limitations requires only those steps that must be performed and does not include steps that are not required to be performed because the condition(s) precedent are not met. As to claim 1, limitations "(d) if the wireless transmission data is not received through the primary transmission channel, switching to a dynamically selected secondary transmission channel, wherein among plural secondary transmission channels, the secondary transmission channel that is not interfered and whose frequency range is the farthest from a frequency range of the primary transmission channel has the highest priority to be selected as the dynamically selected secondary transmission channel by the wireless receiver”; “(e) judging whether the same wireless transmission data through the dynamically selected secondary transmission channel is received within a second time interval”; “(f) if the wireless transmission data is received through the dynamically selected secondary transmission channel, allowing the wireless receiver to be temporarily switched to the transmitting mode, and allowing the wireless receiver to send back a second acknowledgement packet to the wireless transmitter, which is temporarily switched to the receiving mode, wherein the second acknowledgement packet contains at least one of a primary transmission channel change information, a wireless receiver time sequence information and an application function information for controlling the wireless transmitter, and the wireless transmitter sends the additional wireless transmission data through an additional primary transmission channel in response to the primary transmission channel change information”; and “(g) recognizing and processing the wireless transmission data from the dynamically selected secondary transmission channel, continuously receiving the additional wireless transmission data through the additional primary transmission channel that has not been occupied, and then performing the step (a) again" are not required in the claim. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim. As to claims 2, recites contingent limitations “(d) and before the step (e), the data transmission method further comprises steps of: (d1) if the wireless transmission data is not received through the primary transmission channel, checking whether the second acknowledgement packet has been stored in a buffer storage space; (d2) if the second acknowledgement packet has been stored in the buffer storage space, performing the step (e); and (d3) if the second acknowledgement packet has not been stored in the buffer storage space, allowing the wireless receiver to add the primary transmission channel change information to the second acknowledgement packet and store the second acknowledgement packet in the buffer storage space, and performing the step (e)” are not required in the claim. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim. As to claim 4, recites contingent limitations “(f), a frequency range of the additional primary transmission channel is determined by the wireless receiver, and the frequency range of the additional primary transmission channel is identical or close to the frequency range of the dynamically selected secondary transmission channel” are not required in the claim. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim. As to claim 5 recites contingent limitations “wherein the primary transmission channel and the additional primary transmission channel are included in plural primary transmission channels” are not required in the claim. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim. As to claims 6, recites contingent limitations “(l) if the first acknowledgement packet from the wireless receiver is not received, judging whether a sending failure count of the wireless transmitter exceeds a first threshold value within a third time interval”; “(m) if the sending failure count of the wireless transmitter does not exceed the first threshold value, performing the step (i) again, so that the wireless transmitter continuously sends the wireless transmission data through the primary transmission channel”; “(n) if the sending failure count of the wireless transmitter exceeds the first threshold value, the wireless transmitter sending the same wireless transmission data through the dynamically selected secondary transmission channel, wherein among the plural secondary transmission channels, the secondary transmission channel that is not interfered and whose frequency range is the farthest from the frequency range of the primary transmission channel has the highest priority to be selected as the dynamically selected secondary transmission channel by the wireless transmitter”; “(o) judging whether the second acknowledgement packet from the wireless receiver is received, wherein the second acknowledgement packet contains at least one of the primary transmission channel change information, the wireless receiver time sequence information and the application function information for controlling the wireless transmitter”; “(p) if the second acknowledgement packet containing the primary transmission channel change information and from the wireless receiver is received, the wireless transmitter sending the additional wireless transmission data through the additional primary transmission channel in response to the primary transmission channel change information, and performing the step (h) again”; and “(q) if the second acknowledgement packet containing the primary transmission channel change information and from the wireless receiver is not received, judging whether the sending failure count of the wireless transmitter exceeds a second threshold value and all of the plural secondary transmission channels have been broadcast-polled within a second time interval, wherein if the wireless transmitter does not exceed the second threshold value or all of the plural secondary transmission channels have not been broadcast-polled, the wireless transmitter continuously sending the same wireless transmission data through the dynamically selected secondary transmission channels until the sending failure count of the wireless transmitter exceeds the second threshold value and all of the plural secondary transmission channels have been broadcast-polled, and performing the step (h) again.” are not required in the claim. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim. As to claim 7, recites contingent limitations “(p), a frequency range of the additional primary transmission channel is determined by the wireless transmitter, and the frequency range of the additional primary transmission channel is identical or close to the frequency range of the dynamically selected secondary transmission channel” are not required in the claim based on contingent limitations. In Ex Parte Schulhauser, the Patent Trial and Appeal Board ("the Board") held certain claims as unpatentable based on contingent limitations. The examiner states that contingent limitations are not required to be performed under a broadest reasonable interpretation (BRI) of the claim.
