Office Action

§103
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 . The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 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 1,5-7,9,11-14,and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Network Programming -_IP “ Header-Datagrams- Fragmentation “ in view of Kwon ( 2008/0192723). For claims 1,5-7,9,11-14,and 17-20, Network Programming -_IP “ Header-Datagrams- Fragmentation “ discloses a method/system comprising: a method of transmitting an anisochronous packet between devices in a time-sensitive wireless network, the method comprising: determining whether a whole packet to be transmitted is transmittable within a residual time ( See details of flags fields and Header fields and sizes) ; when the whole packet to be transmitted is not transmittable within the residual time, segmenting the packet to be transmitted into packet fragments with a length which is transmittable within the residual time ( See details of flags fields and Header fields and sizes); adding packet fragment information to the packet fragments; and transmitting one of the packet fragments within the residual time( See Detailed Fragmentation Example and details of flags fields and Header fields and sizes). For independent claim 1, Network Programming -_IP “ Header-Datagrams- Fragmentation “ discloses all the subject matter of the claimed invention with the exception of the residual time of a contention periods(CP) in a communication network. Kwon from the same or similar fields of endeavor teaches a provision of the residual time of the contention periods ( See paragraphs 0031 lines 1-12, paragraphs 0013 lines 1-12 and box 120 in figure 1). Thus, it would have been obvious to the person of ordinary skill in the art before the effective filing date of the claimed invention to use the residual time of the contention periods ( See paragraphs 0031 lines 1-12, paragraphs 0013 lines 1-12 and box 120 in figure 1) as taught by Kwon in the communication of Network Programming -_IP “ Header-Datagrams- Fragmentation “ for the purpose of making the system more reliable. For the independent claim 11 is rejected for the same reasons of claim 1. For dependent claims 5-7,9,12-14,and 17-20, Network Programming -_IP “ Header-Datagrams- Fragmentation “ also discloses : wherein the segmenting of the packet to be transmitted into the packet fragments with the length which is transmittable within the residual time comprises generating a packet fragment with a maximum size which is transmittable within the residual time ( See Detailed Fragmentation Example and details of flags fields and Header fields and sizes); wherein a margin value is applied to the packet fragment with the maximum size( See Detailed Fragmentation Example and details of flags fields and Header fields and sizes); wherein the packet fragment information includes: a parameter representing whether there is an additional packet fragment; and a parameter representing a position number of the packet fragment( See Detailed Fragmentation Example and details of flags fields and Header fields and sizes); and wherein the packet fragment information is included in a header of the packet fragment( See Detailed Fragmentation Example and details of flags fields and Header fields and sizes). Claims 2-4,8,10,15, and 16 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Xui et al. (2020/0404704) is cited to show a system which is considered pertinent to the claimed invention.
