Office Action

§112
DETAILED ACTION 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 2-7 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 independent claim 2, the phrase “the belt rings are articulated by a lever, the lever having a pivot axis that differs from the pivot axis of the air spring” is indefinite because it is redundant of the previously recited phrase, “one or more levers . . . coupled to the belt rings and each having a lever pivot axis that tilt about and differ from the air spring pivot axis,” thereby rendering it unclear whether the same elements are being recited in a different manner, or rather, whether some other additional lever and/or pivot axis are being recited. Allowable Subject Matter Claims 2-7 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. Regarding independent claim 2, Applicant’s admitted prior art (see FIGS. 3a-3c) is considered to be the closest prior art of record. Figures 3a-3c do not disclose “one or more levers . . . coupled to the belt rings and each having a lever pivot axis that tilt about and differ from the air spring pivot axis.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to NICHOLAS J LANE whose telephone number is (571)270-5988.
