Office Action

§102 §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 . This Office Action is responsive to the Amendment filed 06 May 2026. Claims 1-9 are currently under consideration. The Office acknowledges the amendments to claims 1-3, 5, and 7-9. 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 1-9 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 “an outer diameter of the active component is increased or reduced along the axis direction of the support member” in the last two lines. It is not clear if this is intended to recite that the reciprocating movement causes the outer diameter of the active component to grow larger and smaller, or merely that the active component has an outer diameter that is larger and smaller at various positions along the axis direction (i.e., when static and not moving; a non-uniform diameter). The specification appears to teach both (“when the active component moves back and forth, the outer diameter of the active component is changed, thereby achieving the expanding and reducing effects of the massage device”; Figure 3). For sake of compact prosecution, the former interpretation will be adopted herein. Claims 2-9 are rejected by virtue of their dependence upon claim 1. 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. Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fima (U.S. Pub. No. 2016/0354277 A1). Fima discloses a drive mechanism (Abstract; Figs. 1-3), comprising a drive member 16, an active component 10/6 and a support member 3/4/5/7; wherein the active component is sleeved on the support member and an inner wall of the active component abuts against an outer wall of the support member (Figs. 3A-B); the drive member is in transmission connection with the active component, so as to drive the active component to make a straight reciprocating movement along an axis direction of the support member; and an outer diameter of the active component is increased or reduced along the axis direction of the support member ([0019]-[0026]). Allowable Subject Matter Claims 2-9 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: none of the prior art of record teaches or reasonably suggests such a configuration of an installation part and a plurality of frameworks, in combination with such a drive mechanism. Response to Arguments Applicant’s arguments with respect to the objection to claim 1 and the rejection of claims 1-9 under 35 U.S.C. 112(b) have been fully considered and are persuasive in light of the amendments. The objection and rejections have been withdrawn. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
