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 . Specification The disclosure is objected to because of the following informalities: Page 6, final paragraph, the paragraph appears to use incorrect reference characters (elongated body should be “3” and the base appears it should be “1”). Appropriate correction is required. Claim Objections Claims 7, 8, and 11 are objected to because of the following informalities: Regarding claims 7 and 11, the recitation “the said” seems to be redundant and appears that it should read either –the—or –said--. The recitation is used in many instances in claim 7, and is also used in line 3 of claim 11. Regarding claim 8, line 1, “wherein pressure surface” should read –wherein said pressure surface--. Appropriate correction is required. 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 7-12 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. Regarding claim 7, line 14, the recitation “the base” renders the claim indefinite because it appears the recitation is referring to a base of the handling unit, but a base is already recited in line 3. Regarding claims 7 and 10, lines 25 and 2, respectively, it is unclear what “to couple exactly” actually requires. What does it mean “to couple exactly”? Regarding claim 11, line 5, the recitation “it” renders the claim indefinite because it is unclear what “it” is referencing. Allowable Subject Matter Claim 7-12 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. The following is a statement of reasons for the indication of allowable subject matter: The prior art of record teaches the idea of a leveling device having multiple parts including a base having a threaded protrusion, and a leveling body attached to the threaded protrusion. The prior art of record also teaches the idea of the leveling body having multiple portions which when pushed together form a single threaded hole. The prior art of record fails to disclose the pressure portion or handling portion having pressure surfaces which engage support surfaces, the pressure surface consisting of an external frustoconical surface engaging the support surface having an internal frustoconical surface.
