Office Action

§102 §103
Detailed Office Action The communication dated 8/17/2029 has been entered and fully considered. Claim 8 is new. Claims 1 and 3 have been amended. Claims 1-8 are pending. 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 . Allowable Subject Matter Claim 8 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. Response to Arguments Applicant argues that two amendments were added to the independent claim: “piece in the second space by rotating around a center axis, the stirring section having an upper surface facing the partition portion” and “upper surface of the stirring section being located between a top end of the discharge port and a bottom end of the discharge port in a direction along the center axis”. The applicant argues that these features are shown in instant Figure 2 as annotated. The Examiner agrees the applicant has support for these features in instant Figure 2. Applicant argues that in the KLAUS publication aqueous suspension P is discharged from the bottom of the secondary chamber. The applicant argues that KLAUS fails to disclose the upper surface of the stirring section between the top and bottom end of the discharge port. In response KLAUS has two discharge ports from the secondary chamber. It is the first port at the bottom which the applicant identified and a second port on the side which is used for recirculation (11). The Examiner has marked up the figure 6 below to show how the side port meets the claim. PNG media_image1.png 566 630 media_image1.png Greyscale Claim Rejections - 35 USC § 102 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. Claims 1-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by DE 10010596A1 KLAUS, hereinafter KLAUS. As for claim 1-3, KLAUS discloses a pulper (storage tank) with two chambers a top chamber (4) and a bottom chamber (5) that is divided by a partition [Figure 6]. KLAUS discloses an adjusting section with a rotating shaft and a stirring member (2) disposed on the outer circumferential portion of the shaft in the top chamber (4) that rotates with the shaft [Figure 6]. KLAUS discloses a stirring section with a second stirring member (20) on the same shaft located in the bottom chamber (5) that rotates together with the shaft [Figure 6]. The stirring section (20) has a top surface which is between the top and bottom end of the side discharge port (11). PNG media_image1.png 566 630 media_image1.png Greyscale As for claim 4, KLAUS discloses a cross-sectional area of the first space is larger than the cross-sectional area of the second space [Figure 6] As for claim 5, KLAUS discloses a humidification section (W) which humidifies the crushed piece by adding water thereto [Figure 6]. As for claim 6, KLAUS discloses a side discharge port (11) that is located at the bottom portion (5) of the tank [Figure 6]. 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 7 is rejected under 35 U.S.C. 103 as being unpatentable over DE 10010596A1 KLAUS, hereinafter KLAUS, in view of Handbook for Pulp and Paper Technologists by SMOOK, hereinafter SMOOK. As for claim 7, KLAUS teaches the features as per above including creating a pulp for papermaking. KLAUS does not disclose a defibrating section, accumulating section or a molding section. SMOOK discloses defibrating pulp to increase its tensile strength [pg. 206 Figure 13-23] and then making paper on a wire (accumulating section) and then pressing the accumulated fibers to consolidate a sheet (molding section) [pg. 228]. At the time of the invention it would be obvious to combine the conventional refining and paper machine of SMOOK to make paper. Thereby creating a value-added product. The pulping of KLAUS and the papermaking of SMOOK both perform the same functions as prior to when they were combined. The person of ordinary skill in the art would expect success from using conventional papermaking to produce paper from recycled pulp. 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.
