Office Action

§112
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 Objections 2. Claim 10 is objected to because of the following informalities: Regarding claim 10, Applicant is requested to change conditional language “when” at line 1 to “in response to” for a positive claiming limitation, since if the condition for performing a contingent step is not satisfied, the performance recited by the step need not be carried out in order for the claimed method to be performed, see MPEP 2111.04. Appropriate correction is required. Claim Rejections - 35 USC § 112 3. 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. 4. Claims 4 and 17 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 pre-AIA the applicant regards as the invention. Claim 4 recites the limitation “each resource element” at lines 8 and 10. There is insufficient antecedent basis for this limitation in the claim. The same remark applies to claim 17. Allowable subject matter 5. Claims 1-3, 5-9, 11-16 and 18-20 are allowed. 6. Claims 4 and 17 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. 7. Claim 10 would be allowable if rewritten or amended to overcome the objection, set forth in this Office action. Conclusion 8. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Ogawa (US 2012/0094709); Park (US 2004/0248541) are cited, and considered pertinent to the instant specification. 9.
