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 . 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 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Park (US 2025/0300779) in view of Lim (US 2025/0193060). 2. As per claim 1, Park teaches a method, comprising: generating one or more small-size multi-resource units (MRUs) or one or more large-size MRUs, or a combination thereof, of a physical-layer protocol data unit (PPDU) in a wide bandwidth greater than 80MHz (Park, ¶0119 “… 80 MHz … PPDU … MRU …”). Furthermore, it is well known in the art to generate MRU or a combination of PPDU for the benefit of improving transmission rates increasing bandwidth, improving reliability, reducing errors, and/or reducing latency see Lim US 2025/0254073 for example ¶0115); and wirelessly transmitting the PPDU in the wide bandwidth, wherein each of the one or more small-size MRUs comprises an aggregate of multiple RUs of 106 tones or fewer, and wherein each of the one or more large-size MRUs comprises an aggregate of multiple RUs of 242 tones or more (Park, ¶0120 “ … MRU … small size … 106 … large size … 242 …”). Therefore, taking the combined teaching of Yu and Lim as a whole, it would have been obvious to one having ordinary skill in the art at the time of the invention to implement the instant limitation for the benefit of improving transmission rates increasing bandwidth, improving reliability, reducing errors, and/or reducing latency. 3. Claim 16 is similarly analyzed as claim 1 for obviousness reasons discussed above. 4. As per claim 2, Park in view of Lim teaches the method of claim 1, wherein the wide bandwidth comprises a 240MHz, 480MHz or 640MHz bandwidth (Lim, ¶0173 0179 “bandwidth … 640 MHz …”), and wherein the PPDU comprises a 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0178 0179 “PPDU … 480 MHz, 640 MHz …”). 5. Claim 17 is similarly analyzed as claim 2 for obviousness reasons discussed above. 6. As per claim 3, Park in view of Lim method of claim 1, wherein the generating of the one or more small-size MRUs comprises generating the one or more small-size MRUs in each 80MHz frequency subblock of the wide bandwidth (Lim, ¶0117), and wherein the generating of the one or more large-size MRUs comprises generating the one or more large-size MRUs in each 80MHz frequency subblock, each 160MHz frequency subblock or each 320MHz frequency subblock of the wide bandwidth (Lim, ¶0117). 7. Claim 18 is similarly analyzed as claim 3 for obviousness reasons discussed above. 8. As per claim 4, Park in view of Lim method of claim 1, wherein the generating of the one or more small-size MRUs comprise generating at least one of: an aggregate of one 52-tone resource unit (RU) and one 26-tone RU (MRU(52+26)) in each 80MHz frequency subblock of a 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); and an aggregate of one 106-tone RU and one 26-tone RU (MRU(106+26)) in each 80MHz frequency subblock of the 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118). 9. Claim 19 is similarly analyzed as claim 4 for obviousness reasons discussed above. 10. As per claim 5, Park in view of Lim method of claim 1, wherein the generating of the one or more large-size MRUs comprise generating at least one of: an aggregate of one 484-tone resource unit (RU) and one 242-tone RU (MRU(484+242)) in each 80MHz frequency subblock of a 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of one 996-tone RU and one 484-tone RU (MRU(996+484)) in each 160MHz frequency subblock of the 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of one 996-tone RU and one 484-tone RU and one 242-tone RU (MRU(996+484+242)) in each 160MHz frequency subblock of the 240MHz, 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of two 996-tone RUs and one 484-tone RU (MRU(2×996+484)) in each 320MHz frequency subblock of a 480MHz or 640MHz PPDU; an aggregate of three 996-tone RUs and one 484-tone RU (MRU(3×996+484)) in each 320MHz frequency subblock of the 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of two 996-tone RUs (MRU(2×996)) in each 320MHz frequency subblock of the 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of three 996-tone RUs (MRU(3×996)) in each 320MHz frequency subblock of the 480MHz or 640MHz PPDU; an aggregate of four 996-tone RUs (MRU(4×996)) in a 480MHz or 640MHz PPDU (Lim, ¶0117 - 0118); an aggregate of five 996-tone RUs (MRU(5×996)) in the 480MHz or 640MHz PPDU; an aggregate of six 996-tone RUs (MRU(6×996)) in the 640MHz PPDU; and an aggregate of seven 996-tone RUs (MRU(7×996)) in the 640MHz PPDU (Lim, ¶0117 - 0118). 11. Claim 20 is similarly analyzed as claim 5 for obviousness reasons discussed above. 12. As per claim 6, Park in view of Lim method of claim 1, wherein the generating of the one or more large-size MRUs comprise generating at least one aggregate of two 996-tone RUs and one 484-tone RU (MRU(2×996+484)) and at least one aggregate of two 996-tone RUs (MRU(2×996)) in a 240MHz bandwidth (Lim, ¶0117 - 0118). 13. As per claim 7, Park in view of Lim method of claim 1, wherein the generating of the one or more large-size MRUs comprise generating at least one aggregate of five 996-tone RUs (MRU(5×996), at least one aggregate of four 996-tone RUs (MRU(4×996)) and at least one aggregate of three 996-tone RUs (MRU(3×996)) in a 480MHz bandwidth (Lim, ¶0117 - 0118). 14. As per claim 8, Park in view of Lim method of claim 7, wherein the generating of the one or more large-size MRUs further comprise generating the one or more large-size MRUs with a subcarrier spacing (SCS) of 78.125 kHz (Lim, ¶0142). 15.
