Office Action

§103 §112 §DP
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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-15 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 10968065 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the instant application and of the patent are drawn to the same invention of an emergency stop cutting mechanism for a web winder, but differ only in specificity and obvious wording changes. The invention broadly claimed in this application is obviously encompassed by the claims of the patent. Claims 1-15 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 12122623 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the instant application and of the patent are drawn to the same invention of an emergency stop cutting mechanism for a web winder, but differ only in specificity and obvious wording changes. The invention broadly claimed in this application is obviously encompassed by the claims of the patent. 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. 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 1-15 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 pre-AIA the applicant regards as the invention. In claim 1, line 7, “it is biased across” is indefinite and vague. Is applicant referring to the blade that is being biased across the web? In claim 5, line 1, “a ball slide” is indefinite and vague. Which element constitutes “a ball?” Claim 15 recites the limitation "the housing" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim Rejections - 35 USC § 103 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 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. 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 1-2 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Enwald et al., US 2010/0051736 A1, in view of Hatakeyama, US 2013/0276609 A1 and further in view of Eder et al., US 2015/0346106 A1. Regarding claims 1-2 and 15, Enwald ‘736 shows a method of using the device in figures 1-3c. Enwald ‘736 discloses a web winder 1 (i.e. which has a housing 2 with a buffer 8 as stabilizing the web) comprising an input 5 that receives web W on a feed path from an upstream handling device (i.e., a supply side for web), a take up roll 4 that is driven to form the web into a roll as it is delivered at the input, and an emergency stop cutting mechanism 6 located between the input 5 and the take up roll 4, (i.e., which can be turned on/off since the device is not manually operated), release air jets at a non perpendicular angle (see cutting lines, figures 3a-c) to a feed direction of the feed path, see figures 1-3c. PNG media_image1.png 544 416 media_image1.png Greyscale Enwald ‘736 does not explicitly show any signal connected to the cutting mechanism and biasing across the web to separate the web. Eder ‘106 discloses the concept of connecting a severing device 39 to the comparator 38 to the drive 40/a computer circuit 14 (i.e., a controller) to send a signal, see column [0021]. Hatakeyama ‘609 discloses the concept of using a blade B with a biasing mechanism 35 to separate the web, see figure 2. It would have been obvious to one of ordinary skill in the art at the time the invention was made to modify the apparatus of Enwald ‘736 to include a biasing blade and using some sort of controller to send a signal to the cutter as suggested by Hatakeyama ‘609 and Eder ‘106, to enhance severing of the web material as it forms the roll. Furthermore, since all of the claimed elements were known in the prior art and one skilled in the art could have combined the elements as claimed by known methods with no change in their respective functions, and the combination would have yielded predictable results to one of ordinary skill in the art at the time of the invention. Allowable Subject Matter Claims 3-14 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. The claims 3-14 are patentable over the prior art of record because the teachings of the references taken as a whole do not show or render obvious the combination set forth in claims 3-14, including every structural element recited in the claims. None of the references of the prior art teach or suggest the elements of the device as advanced above and such do not provide the necessary motivation, absent applicant's specification, for modifying the device in the manner required by the claims.
