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 . Response to Arguments Applicant’s arguments, regarding the previous 112 rejections and the Y-axis drawing objection have been fully considered and are persuasive. The rejections and objections have been withdrawn. Applicant's arguments regarding the remaining drawing objections have been fully considered but they are not persuasive. Applicant argues that it is not necessary to illustrate “every feature of the invention” as “there is no rule that all words in the claim be illustrated”. The objected to portions of the claim, the Presser elements” of claim 5-6; and the “packaging machine” and “support structure” of claim 13 do not represent mere “words”, but rather extremely important features of the invention. According to the MPEP, 608.02(d) Complete Illustration in Drawings [R-07.2015] -37 C.F.R. 1.83 Content of drawing; (a) The drawing in a nonprovisional application must show every feature of the invention specified in the claims. However, conventional features disclosed in the description and claims, where their detailed illustration is not essential for a proper understanding of the invention, should be illustrated in the drawing in the form of a graphical drawing symbol or a labeled representation (e.g., a labeled rectangular box). In addition, tables that are included in the specification and sequences that are included in sequence listings should not be duplicated in the drawings. (b) When the invention consists of an improvement on an old machine the drawing must when possible exhibit, in one or more views, the improved portion itself, disconnected from the old structure, and also in another view, so much only of the old structure as will suffice to show the connection of the invention therewith. (c) Where the drawings in a nonprovisional application do not comply with the requirements of paragraphs (a) and (b) of this section, the examiner shall require such additional illustration within a time period of not less than two months from the date of the sending of a notice thereof. Such corrections are subject to the requirements of § 1.81(d). Applicant’s arguments with respect to the previous rejection have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the – “the sealing elements comprise a plurality of rolling elements configured to be placed in indirect contact with at least one of the edges to achieve a sealing by an indirect rolling contact” of claims 1 and 13; and “said flexible element has a first surface arranged proximal to said rolling elements and a second surface opposite to said first surface configured to contact said edges of a film to seal them together via a translation of the indirect rolling contact through the flexible element” of claims 1 and 13; and “Presser elements” of claim 5-6; and “packaging machine” and “support structure” of claim 13; must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. 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. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 13, and all subsequent dependent claims are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding claim 1 and 13, the claim limitation “the sealing elements comprise a plurality of rolling elements configured to be placed in indirect contact with at least one of the edges to achieve a sealing by an indirect rolling contact” and “said flexible element has a first surface arranged proximal to said rolling elements and a second surface opposite to said first surface configured to contact said edges of a film to seal them together via a translation of the indirect rolling contact through the flexible element” is not found in the specification and therefore represents both a written description violation and a new matter situation. Appropriate correction is required. 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, 13, and all subsequent dependent claims 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. the claim limitation “the sealing elements comprise a plurality of rolling elements configured to be placed in indirect contact with at least one of the edges to achieve a sealing by an indirect rolling contact” and “said flexible element has a first surface arranged proximal to said rolling elements and a second surface opposite to said first surface configured to contact said edges of a film to seal them together via a translation of the indirect rolling contact through the flexible element” renders the claim indefinite, as the metes and bounds of the limitation cannot be interpreted from either the claims nor the specification. In the interest of compact prosecution, the claims will be examined sans the portion cited in the 112A/B rejections. 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. Claims 1-10, 12-13 are rejected under 35 U.S.C. 103. The previous citations and references from the 5/2/2025 Non-Final rejection contain the same subject matter as the current claims and are hereby incorporated by reference (Examiner’s note – absent the subject matter of the 112A/B rejections and the drawing objections, the amendments to claims 1 and 13 merely incorporate the previously rejected and cited material of claim 11). 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.
