Office Action

§102
DETAILED ACTION Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot because of the new ground of rejection. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-4, 7, and 12-14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Naganathan et al. (US 5,390,949). In Re claim 1, Naganathan et al. discloses a spring device for a motor vehicle (see figs. 11 and 12), comprising: a spring unit (110); a stiffness adjusting unit (113, 120), comprising: a stiffening element (120) attached to the spring unit and enclosing the spring at least in sections (see fig. 12); and a control apparatus (113) for actuating the stiffening unit. In Re claim 2, col. 1, lines 43-45 disclose the known use of a fiber reinforced composite spring material. In Re claim 3, figs. 1 and 2 depict a leaf spring with a stiffness adjusting unit. In Re claim 4, see layered leaf spring configuration (16) and surrounding stiffness adjusting elements (18). In Re claim 7, see stiffness adjusting element (120) in fig. 12. In Re claim 12, see col. 3, lines 38-46. In Re claim 13, the piezoelectric stiffness adjusting element is controlled by an electrical current. In Re claim 14, the stiffness adjusting element is a piezoelectric material. Allowable Subject Matter Claims 5, 9, 10, and 15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
