Office Action

§103
DETAILED ACTION Applicants’ response filed 9/18/26 has been considered. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1, 3-6 and 8-20 are pending. Prior art rejections are maintained in view of remarks made herein. See prior office action for details. Application is pending. Response to Arguments Applicants’ arguments filed 9/18/2026 have been fully considered but they are not persuasive. For example, claim 1 recites: PNG media_image1.png 482 674 media_image1.png Greyscale Applicants contend the prior arts do not teach or fairly suggest the added limitations in the claim. Particularly, Applicants contend the prior art doesn’t teach or suggest, “the control frame further comprising a prepadding frame check sequence (FCS) field that is located directly after the MIC information, the prepadding FCS field directly followed by additional padding, the additional padding directly followed by another FCS field.” The Examiner respectfully disagrees and would like to point out that the rejection was based on obviousness rationale. Hwang (reference D1) teaches (i.e., Figures 7-8 and paragraphs 0023, 0027, 0030, 0077-0085) MIC followed by padding. The Examiner would like to point out that D1 teaches the concept of additional padding (i.e., paragraph 0030). Padding with additional padding is not something that is novel and is based on obvious design choice. Therefore the claims remain rejected and not patentably novel over the prior arts. Prior art rejections are maintained. See prior office action. Applicants are encouraged to formulate claim language that differentiates the claims from the prior arts. Application is pending. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
