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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Drawings The drawings are objected to because figs. 1, 3, 4, 6, 7, and 9 are cross-sectional views presented without required oblique hatching. See 37 CFR 1.84(h)(3) and PCT Rule 11.13(b). The drawings are objected to because fig. 8 is submitted as a photograph, but it is not justified as it is not the only practical medium for illustrating the claimed invention. See 37 CFR 1.84(b)(1) and MPEP § 1825. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification The use of the term Alcrona, which is a trade name or a mark used in commerce, has been noted in this application. The term should be accompanied by the generic terminology; furthermore the term should be capitalized wherever it appears or, where appropriate, include a proper symbol indicating use in commerce such as ™, ℠, or ® following the term. Although the use of trade names and marks used in commerce (i.e., trademarks, service marks, certification marks, and collective marks) are permissible in patent applications, the proprietary nature of the marks should be respected and every effort made to prevent their use in any manner which might adversely affect their validity as commercial marks. Claim Objections Claim 8 is objected to because of the following informalities: To improve clarity, in claim 8 on line 2, a comma should be placed between “jigs” and “each,” and on lines 2–3, a comma should be placed between “panels” and “are.” 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 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) 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): (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). The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) 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). The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) 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), 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), 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), 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: The transfer part in claim 1 (given the submitted figures, this is clearly rollers or similar). Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f), 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), applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) (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). 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. Claim 14 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim 14 refers to “the plurality of the pattern jigs.” However, this limitation lacks antecedent because claim 14 depends from claim 7, but the plurality of pattern jigs is introduced in claim 8. The claim should be amended to depend from claim 8. Allowable Subject Matter Claims 1–7 and 9–13 are allowed. Claim 8 would inherit allowability if rewritten or amended to overcome the objection set forth in this Office action. Claim 14 would inherit allowability if rewritten or amended to overcome the rejection under 35 U.S.C. 112(b) set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: Scherner et al. (EP 3415265 A1, cited by Applicant) is likely the most relevant prior art of record, particularly as it discloses an apparatus directed to battery electrode manufacturing, as well as an opening with a width that widens in the direction of the laser beam. However, Scherner’s limp wheel 114 does not properly qualify as a panel, which should be understood to be a generally two-dimensional piece, even if, broadly speaking, possibly one with a great thickness and curvature, as well as possibly joined to other non-panel pieces. Summerer et al. (US Pub. 2018/0133838) is relevant for disclosing a gap that widens in the direction of the laser beam, but it does not disclose a panel with the claimed opening because it discloses only a gap between the entirety of two separate pieces. Kretschmar et al. (DE 10 2017 216 133 A, cited by Applicant), Graf (WO 2009/065429 A1, cited by the Office), and Watanabe (WO 2014/041588 A1, cited by the Office) are similar to Summerer. Zandbergen et al. (NL 1026942 C2, cited by the Office) appears to disclose a panel proper, but this apparatus uses an electron beam that cannot be substituted with a laser beam. Kang et al. (KR 2016-0138741 A, cited by the Office), Imai et al. (CN 104203544 A, cited by the Office), and Bae et al. (KR 2021-0001077 A, cited by the Office) are also cited as relevant prior art.
