Office Action

§103
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination (RCE) under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed June 25, 2025 in this application after Final Rejection Office action. Since this application is eligible for continued examination under 37 CFR 1.114, the previous Final Rejection with the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on August 22, 2025 has been entered. Response to Arguments Applicant's arguments filed August 22, 2025 have been fully considered but they are not persuasive. Applicant argues throughout that the previously cited prior art fail to teach or suggest “adding a second header to each of the plurality of data segments, wherein the second header comprises description information related to the data segment, and wherein the description information comprises at least one of: a segmentation information (SI); or a segment offset (SO), wherein each of the plurality of data segments is a MAC service date unit (SDU) segment.” Examiner disagrees. Segmenting data units, as well as, attaching/adding headers to multiple data units is known in the art as demonstrated in the previously cited prior art and newly cited prior art of Vajapeyam (USPGPUB 20170041766.) Examiner acknowledge Applicant amendment whereby Applicant has added the limitation of canceled claim 3 into the independent claims. However, the claims are not in condition for allowance because the combined prior art as cited teaches “adding a second header to each of the plurality of data segments, wherein the second header comprises description information related to the data segment, and wherein the description information comprises at least one of: a segmentation information (SI); or a segment offset (SO), wherein each of the plurality of data segments is a MAC service date unit (SDU) segment.” In light of Applicant amendment, the previous rejections have been modified to reflect the most current amendments. See rejections that follows. Claim Rejections - 35 USC § 103 7. 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. 8. 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. 9. Claims 1-2, 18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kashima et al (US PGPUB 2008/0009289) in view of Kim et al (US Patent 10,091,686, hereafter; Kim(686) and Jung et al (US PGPUB 2021/0274587) and KWON et al (US Patent 10,142,706.)

Although Kashima fail to teach adding a first header to each of the plurality of data units, wherein the first header comprises an indication indicating whether a data unit comprises a data segment, and wherein the first header comprises a one-bit indicator; and setting the one-bit indicator in the first header of each of the plurality of data units to a value to indicate that the data unit comprises the data segment, Kim686 further disclose adding a first header to each of the plurality of data units (see, Fig. 2B & 4, 2 col. 2, line 49-56, col. 3, line 13-15, attaching header to all of the many of data units ) wherein the first header comprises an indication indicating whether a data unit comprises a data segment (see Fig. 6A, col. 25, line 5-26, first headers include flag bit indicating data unit associated with segment), and wherein the first header comprises a one-bit indicator (see col. 25, line 5-26, first headers include 1-bit flag indication); and setting the one-bit indicator in the first header of each of the plurality of data units to a value to indicate that the data unit comprises the data segment (see Fig. 6A, 6B, 7 & 10, col. 16, line 25-31, col. 25, line 5-26.) Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date to implement adding a first header to each of the plurality of data units, wherein the first header comprises an indication indicating whether a data unit comprises a data segment, and wherein the first header comprises a one-bit indicator; and setting the one-bit indicator in the first header of each of the plurality of data units to a value to indicate that the data unit comprises the data segment as taught by Kim(686) with the combined teachings of Kashima for the purpose of providing communication clarity associated with payload segmentation and reassembly . Although Kashima and Kim686 fail to teach obtaining, at the MAC layer, the plurality of data units from a layer immediately above the MAC layer, wherein the plurality of data units are grouped by at least one of: a Quality of Service (QoS) flow and a data radio bearer (DRB), in analogous art, Jung et al disclose obtaining, at the MAC layer, the plurality of data units from a layer immediately above the MAC layer, wherein the plurality of data units are grouped by at least one of: QoS flow and DRB (see Fig. 1D, 1FA, para: 0077, 0095, 0153, 0156, group information (reassembled data) obtained by MAC layer, whereby the data sets are grouped by DBRS and QoS.) Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date to implement obtaining, at the MAC layer, the plurality of data units from a layer immediately above the MAC layer, wherein the plurality of data units are grouped by at least one of: a Quality of Service (QoS) flow and a data radio bearer (DRB) as taught by Jung et al with the combined teachings of Kashima and Kim(686) for the purpose of providing communication clarity as well as minimizing communication delay associated with payload segmentation and reassembly. Although, Kashima, Kim(686) and Jung fail to teach adding a second header to each of the plurality of data segments, wherein the second header comprises description information related to the data segment, and wherein the description information comprises at least one of: a segmentation information (Sl); a sequence number (SN); or assignment offset (SO), in analogous art, KWON et al teaches segmented packet maybe included in a segmented packet, whereby an extended header (second header) maybe included. The extended header may include a sequence offset (SO) or a segmentation information (SI) (see col. 14, line 3 thru line 20, header may include (SO) or (SI).) Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date to implement adding a second header to each of the plurality of data segments, wherein the second header comprises description information related to the data segment, and wherein the description information comprises at least one of: a segmentation information (SI); a sequence number (SN); or a segment offset (SO) as taught by KWON with the combined teachings of Kashima, Kim(686) and Jung for the purpose of providing communication clarity associated with assemble and reassembling of PDU, wherein each of the plurality of data segments is a MAC SDU segment (see para: 0030, segment MAC SDUs.) Regarding claim 2, Kashima disclose wherein each of the plurality of data units is a MAC service data unit (SDU) (see para: 0030-0032, data units is MAC SDUs.) 10. Claims 10-12 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Pani et al (US PGPUB 20080188224) in view of and Kim et al (US Patent 10,091,686, hereafter; Kim(686) and KWON et al (US Patent 10,142,706) AND Kashima et al (US PGPUB 2008/0009289.) Regarding claim 10 and 19, Pani et al disclose performed by a receiver module in a wireless communication system, the method comprising: reassembling a plurality of data segments at a medium access control (MAC) layer to construct at least one of a plurality of reassembled data units for a plurality of logical channels (see fig. 1B, abstract, para: 0002-0005, data units (PDU and SDU) associated with logic channel.) In addition, Pani disclose at least one processor (see Fig. 1A, 1B, para: 0142-0144) configured to: reassemble a plurality of data. Although Pani fail to teach wherein the plurality of data segments are allocated with a plurality of sequence numbers in sequential order, in analogous art, Kim(686) et al disclose plurality of data segment shares IP header, such as sequence number in sequential order (see col, 10 & 11, fig. 2B, 6B, 14B-14D, : 0166, 0170, data segments in sequential order.)
