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 . Election/Restrictions Applicant’s election without traverse of Group I, Species A in the reply filed on 11/3/25 is acknowledged. Claims 9, 10 and 16-20 have been withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Group and Species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 11/3/25. 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. Claim 2 is 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 2 discloses “said support includes a support” on line 4. This language is indefinite as it is unclear whether “a support” is the same or different “a support” as disclosed in claim 1. Claim 8 discloses “supports” on line 2. This language is indefinite as it is unclear whether the “support” is the same or different “a support” as disclosed in claim 1. Claim 8 recites the limitation "with supports" in line 2. There is insufficient antecedent basis for this limitation in the claim. Examiner suggests amending such as “with the supports” to point out the supports are the same supports, as disclosed in claim 1.
