Office Action

§112
DETAILED ACTION Applicant’s response filed 5/19/2026 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 1-4, 6-11, 13-18 and 20-23 are pending. Prior rejections are withdrawn (for now) until the claims are clear in view of amendments and remarks filed. New rejections under 35 USC 112 are presented in view of amendments and remarks. Application is pending. Response to Arguments Applicant’s arguments with respect to claims 1-4, 6-11, 13-18 and 20-23 have been considered but are moot because the new ground of rejection. 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 1-4, 6-11, 13-18 and 20-23 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. For example, claim 1 recites: PNG media_image1.png 329 674 media_image1.png Greyscale The claim states, “…constructing a base matrix comprising a plurality of columns, wherein each of the plurality of columns has the same Hamming weight…” It is not clear from the claim if the same Hamming weight for each column is something that is just done initially or if this is property that is maintained in the following steps. Do the plurality of permuted matrices each have column weights that are the same? Independent claims 8 and 15 are rejected for similar reasons. Respective dependent claims are rejected at least based on dependency. Corrections are requested. It is the Examiner’s conclusion that the claims of the present application, as presented, are not clear. Applicant is encouraged to formulate claim language that clearly defines the novelty of the application. If Applicant believes an interview with the Examiner might be useful then, Applicant is welcome to contact the Examiner with proposed amendments for a discussion. 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.
