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 1, 3-4, 6-7, and 9 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.
Regarding claim 1, this claim recites “a data packet too big frame is received” in line 21 and “being rejected ” in line 26. The boundaries of “a data packet too big frame is received” and “being rejected” is/are unclear because the claim(s) does not provide a discernable boundary on what performs the function(s). The recited function(s) does not follow from the structure recited in the claim, i.e., a processor or a memory, so it is unclear whether the function(s) requires some other structure or is simply a result of operating the Wi-Fi controller in a certain manner. Thus, one of ordinary skill in the art would not be able to draw a clear boundary between what is and is not covered by the claim(s). See MPEP 2173.05(g) for more information.
Regarding claims 3, 6, and 9, the claim limitation “receives a packet too big frame the access point” is unclear. For purposes of examination, the Examiner interpreted the claim as “receives a packet too big frame from the access point”, as supported by specification ¶[009].
Regarding claim 4, this claim recites the limitation “the Wi-Fi controller” in line 7. There is insufficient antecedent basis for this limitation in the claim.
Regarding claim 6, this claim recites the limitation “the CAPWAP module” in line 1. There is insufficient antecedent basis for this limitation in the claim.
Regarding claim 7, this claim recites the limitations “the method” in line 1 and “the Wi-Fi controller” in line 7. There is insufficient antecedent basis for this limitation in the claim.
Regarding claim 9, this claim recites the limitation “the CAPWAP module” in line 1. There is insufficient antecedent basis for this limitation in the claim.
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.
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.

CAPWAP control messages are management messages exchanged between WTP 231 and AC 230. CAPWAP data and control packets are sent over separate ports. Since both data and control packets may exceed a Maximum Transmission Unit (MTU) length, the payload of a CAPWAP data or control message may be fragmented ), the Wi-Fi controller comprising (FIG. 7 shows a schematic diagram of an access point controller (AC)):
a processor (FIG. 7 Processor (301));

CAPWAP control messages are management messages exchanged between WTP 231 and AC 230. CAPWAP data and control packets are sent over separate ports. Since both data and control packets may exceed a Maximum Transmission Unit (MTU) length, the payload of a CAPWAP data or control message may be fragmented);

Klein, fails to explicitly state, however, Luo Sheng, in the same or similar field of endeavor teaches: a fragmentation module to configure a station from the plurality of stations for fragmentation, and when a data packet too big frame is received from the access point, activating fragmentation at the station ( see Luo Sheng ¶[0011], The sending end performs fragmentation processing on the data packets that need to be fragmented according to the MTU rule corresponding to the link between the sending end and the receiving end; ¶[0012], The sending end performs fragmentation on the selected data packet to obtain multiple new data packets; ¶[0136] The frame structure of the data packet includes the 802.3 frame structure and the 802.11 frame structure, and the frame format of the data packet includes the IPv6 frame format), wherein the data packet too big frame is responsive to a data packet being sent from the station to the access point and then being rejected as too big when sent from the access point to a network device due to the data packet being too large for processing by the network device (see Luo Sheng ¶[0011], The sending end performs fragmentation processing on the data packets that need to be fragmented according to the MTU rule corresponding to the link between the sending end and the receiving end; ¶[0032] Preferably, the sending end selects the data packets to be fragmented from all data packets based on the determined parameter information of each data packet, specifically including: ¶[0033] The sending end divides all data packets into long frame data packets and short frame data packets according to the parameter information of each data packet; ¶[0034] The sending end treats long frame data packets as data packets that need to be fragmented;¶[0035], By fragmenting long frame data packets, it is ensured that data packets can be transmitted normally in the CAPWAP tunnel), and wherein the fragmentation activated at the station ( see Luo Sheng ¶[0011], The sending end performs fragmentation processing on the data packets that need to be fragmented according to the MTU rule corresponding to the link between the sending end and the receiving end; ¶[0012], The sending end performs fragmentation on the selected data packet to obtain multiple new data packets ) and configured based on a maximum data packet size allowed by the network device (see Luo Sheng, ¶[0245] Preferably, the segmentation processing unit 1002 is specifically used for: ¶[0246] According to the Maximum Transmission Unit (MTU) rule corresponding to the link between the sending and receiving ends, the data packets that need to be fragmented are fragmented).

CAPWAP control messages are management messages exchanged between WTP 231 and AC 230. CAPWAP data and control packets are sent over separate ports. Since both data and control packets may exceed a Maximum Transmission Unit (MTU) length, the payload of a CAPWAP data or control message may be fragmented; see Luo Sheng, ¶[0035] By fragmenting long frame data packets, it is ensured that data packets can be transmitted normally in the CAPWAP tunnel; ¶[0139] Data packets with a frame length greater than the maximum transmission unit value corresponding to the transmission link between the sending end AP and the receiving end AC, i.e., the CAPWAP tunnel, are classified as long frame data packets; ¶[0246] According to the Maximum Transmission Unit (MTU) rule corresponding to the link between the sending and receiving ends, the data packets that need to be fragmented are fragmented).

Known work in one field of endeavor (Luo Sheng prior art) may prompt variations of it for use in either the same field or different one (Klein prior art) based on design incentives ( improving the processing efficiency of data packets) or other market forces if the variations are predictable to one or ordinary skill in the art.
