Office Action

§112
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 § 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 1-5 & 9 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. Claim 1 recites the limitation "the second wall" in line 10. There is insufficient antecedent basis for this limitation in the claim. The claim will be examined as if it read –second vertical wall section--. Appropriate correction is required. Claim 5 recites the limitation "free portion" in line 1. There is insufficient antecedent basis for this limitation in the claim. The claim will be examined as if it read –free hanging portion--. Appropriate correction is required. Claim 9 recites the limitation "each engagement bracket of the two engagement brackets" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. The claim will be examined as if it were dependent from claim 6. Appropriate correction is required. Allowable Subject Matter Claims 6-8, 10 & 11 are allowed. Claim 1 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. Claims 2-5 & 9 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The prior art teaches brackets for installing a chassis into a wall sleeve comprising two wall sections having tab sections. The prior art does not teach a bracket for installing chassis into a wall sleeve comprising a first wall section having two slots; and a second vertical wall section having two tab sections sized to fit into a slot. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure because it gives a general state of the art.
