Office Action

§103 §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 . 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. Response to Arguments Applicant’s arguments, see the Remarks, filed 23 July 2026, with respect to the rejection of Claim 1 have been fully considered and are persuasive. The Final Rejection of 17 June 2026 has been withdrawn. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “an elastic member” in claim 1. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 1-2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Muraoka et al (US 20210239231) in view of Hansen III et al (US 6460567). Regarding Claim 1, Muraoka et al disclose a fluid control valve (Figures 1-3). The valve comprising: a direct-acting servomotor (31; ¶ 36), a valve element (20), a valve seat (S), and a passage (from 11 to 12 via 13; Figure 1), and configured to perform controlling of a control fluid to flow through the passage by moving the valve element with the servomotor (¶ 28) between a valve open position (Figure 2B) at which the valve element is separated from the valve seat (¶ 27; Figure 2B) and a valve close position (Figure 2A) at which the valve element is contacted with the valve seat (at S; ¶ 27), wherein the fluid control valve (Figures 1-3) is provided with an elastic member (16; ¶ 34) to apply an urging force to the valve element in a closing direction (¶ 34), the servomotor (31) is provided with a drive shaft (40) to operate the valve element (¶ 45; Figures 2A and 2B), and is configured to be energized to electromagnetically move the drive shaft in a linear direction (¶ 37), a position control mode (when the drive unit 30 drives the valve body 20 in the retracting direction as disclosed in ¶ 35) to control the drive shaft to move to a target position (to at a location to remove the valve body 20 from the seat S; Figure 2B; ¶ 35) and a thrust control mode (with the power to the drive unit at zero as disclosed at ¶ 64) to control the drive shaft to obtain a target thrust are provided (where the target thrust is 0; ¶ 64), and while the valve element moves from the valve open position to the valve close position (from Figure 2B to Figure 2A in the direction D1), the fluid control valve is provided with a control program configured to control the servomotor with the position control mode (via controller 34; ¶ 36) until the valve element reaches a predetermined position before reaching the valve close position (since drive shaft 40 only extends to the position of 2A, with the final closure formed solely by the bias of spring 16) from the valve open position and to switch control of the servomotor from the position control mode (¶ 64 by cutting off power to the drive unit) to the thrust control mode with the target thrust of zero (¶ 64) to bring the valve element to reach the valve close position from the predetermined position only by the urging force (of 16; Figure 2a), but fails to expressly disclose where the servomotor is provided with a coil, where the coil is configured to be energized to electromagnetically move the drive shaft in a linear direction. Hansen III et al teach a fluid control valve (Figure 1) with a direct-acting servomotor (40; directly acting on rotor 41) and provided with a coil (48; where a stator is coil winding and therefore is a coil) that is configured to be energized to electromagnetically move the drive shaft in a linear direction (to move shaft 30 shown in Figure 1 to open and close the valve). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the motor of Muraoka et al with the servomotor as taught by Hansen III et al for the advantage of combining prior art elements according to known methods (a servomotor to operate a valve within the valve of Muraoka et al) to yield predictable results (to drive the valve between the open and closed positions). Regarding Claim 2, Muraoka et al disclose where the control program (via controller 34; ¶ 36) is configured to maintain a state in which the valve element is at the valve close position after the valve element reaches the valve close position by the thrust control mode with the target thrust of zero (¶ 64 discloses where keeping the valve closed does not require a thrust of the motor). Allowable Subject Matter Claims 3-4 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.
