Office Action

§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 . Objections to the Abstract 1. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The abstract of the disclosure is objected to because of legal phraseology with words like “comprising” and “comprising” as well as the numeral FIG. 6. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Objections to the Specification 2. The disclosure is objected to because of the following informalities: at page 13 first paragraph the vacuum is not given a reference numeral to correspond to drawings. Appropriate correction is required. Objections to the Drawings 3. 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 vacuum must be shown or the feature canceled from the claims. 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. Rejections Double Patenting 4. 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 1-19 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of copending Application No. 18/826,657 (‘657). Although the claims at issue are not identical, they are not patentably distinct from each other because independent claim 1 of the present application is encompassed with independent claim 1 and claim 10 of (‘657). This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Rejections 35 U.S.C. § 112 5. 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. Independent claim 1 recites the limitation "a vacuum" in line 12 but it not clear whether the vacuum is an element of the claim since it is not depicted in the drawings that delineates exactly where the vacuum is created in the chamber with lines or arrows. Independent claim 1 recites the limitation "a vacuum" in line 12 while claim 12, which depends from claim 1, recites in line 5 recites “a vacuum”. It is not clear whether the “vacuum” mentioned in independent claim 1 is the same vacuum mentioned in claim 12. There is insufficient antecedent basis for this limitation in the claim. Reasons For Allowance 6. The following is an examiner’s statement of reasons for allowance: the closest prior art of record is U.S. Patent Publication (2004/0084062) to Theiss, Jr. et al. Theiss, Jr. et al. base module (10) including lower housing (12) and upper housing (14) including a suction inlet (18). Additionally, Theiss, Jr. et al. including a brush assembly (20) and a nozzle (16) (See paragraph [0016] of Theiss, Jr. et al.). However, Theiss, Jr. et al. is silent regarding “that the brush body …in the suction chamber….a drive device configured to rotate the brush body about the axis of rotation, the drive device including a drive motor, a motor compartment fixed relative to the main body, the drive motor at least partially arranged in the motor compartment, and the motor compartment and the drive motor being at least partially arranged in a motor housing delimited by the brush body, and an air-cooling circuit fluidly connected to the suction chamber, the suction head configured so that, when a vacuum is generated in the suction chamber, air is sucked into the air-cooling circuit from outside the rotating brush and is circulated in the air-cooling circuit, the air-cooling circuit includes a first circuit portion which is partially delimited by the drive motor and a second circuit portion which is partially delimited by the motor compartment and the brush body and which is located downstream of the first circuit portion and the air-cooling circuit is configured so that, when the vacuum is generated in the suction chamber, the air circulated in the first circuit portion flows at least partially inside the drive motor , and so that the air circulated in the second circuit portion flows at least partially between the motor compartment and the brush body”, as required in independent claim 1. Conclusion 7. 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.” Any inquiry concerning this communication or earlier communications from the examiner should be directed to MICHAEL D.
