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 . Claim Interpretation The claims recite that the rate of the regulating member will be adjusted “with a resolution lower than or equal to 1 second per day.” The specification does not define “resolution” and what the term “resolution” means is not immediately clear. For the purpose of examination, it is being interpreted as meaning the time loss. The claims are therefore being read as saying that the timepiece and regulating member will lose at most 1 second per day. 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. In claim 1, the “means for adjusting the rigidity” comprises (1) a flexible element ([0043]) having a flexural pivot of two flexible blades joined to a rigid support ([0045]) and (2) prestressing means ([0029]) having a lever connected to the flexible element ([0031]) and to a secondary flexible blade ([0047]) connected to a semi-rigid structure ([0033]) connected to the rigid support ([0048]). In claim 1, the “index-assembly system for adjusting the rate of the balance spring” and that “is configured to adjust the rate of the regulating member with a resolution lower than or equal to 0.1 second per day” comprises setting references ([0019]), a stud-holder comprising first and second studs mechanically linked to a resilient element ([0020]), two eccentrics ([0052]), an arm and a cam ([0024]), and a spring exerting a force between a first and second portion to hold the arm against the cam ([0025]). In claim 10, the “prestressing device for applying a variable force or torque” comprises a lever ([0031]) and semi-rigid structure ([0033]). Because these claim limitations are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, they 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 § 112 The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 18-19 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claims 18-19 recite that the resolution of the rate adjustment will be lower than or equal to 0.5 s/day or 0.1 s/day, respectively. However, claim 1 already recites a rate adjustment with a resolution of 0.1 s/day, so claims 18-19 fail to narrow claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Response to Arguments Regarding the enablement rejection of claim 1 due to the alleged lack of support for the claimed “resolution lower than or equal to 0.1 second per day,” Applicant responded by arguing that the recited resolution is enabled by the disclosed structure and cites [0066] of the specification, which states that “the configuration of the regulating member 1 allows achieving such accuracy.” Although claim 1 does not explicitly recite any “configuration,” claim 1 invokes interpretation under 112(f) such that structure disclosed in the specification has been interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. Allowable Subject Matter Claims 1-17 and 20 are allowable. The following is an examiner’s statement of reasons for allowance: regarding claim 1, Bennett Jr. et al. (US 2379780) discloses that changes in length of five-one hundred thousandth of an inch in a hairspring will cause a change in rate of 0.1 s/day, but does not disclose structure capable of controllably setting a hairspring’s resolution with such specificity. Favre et al. (US 20220137559) discloses that “a highly crafted mechanical pendulum” can achieve a resolution of less than 0.1 s/day, but does not disclose a balance spring having such resolution. The prior art does not show or suggest an index-assembly system for adjusting the rate of a balance spring, wherein the balance spring includes means for adjusting the rigidity of the balance spring and the index-assembly system is configured to adjust the rate of the regulating member with a resolution lower than or equal to 0.1 second/day, and wherein the index-assembly system includes setting references corresponding to said resolution. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Applicant's amendment necessitated the new grounds 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.
