Office Action

§112 §DOUBLEPATENT
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 . Claim Objections Claims 1-14 are objected to because of the following informalities: In line 3 of claim 1, it is believed “A” should be changed to --a--. In lines 3-4 of claim 1, it is believed the phrase “vehicle’s windshield” should be changed to remove the possessive language, such as --a windshield of the vehicle--. In lines 21-22 of claim 1, it is believed the phrase “vehicle’s windshield washer reservoir” should be changed to remove the possessive language, such as --a windshield washer reservoir of the vehicle--. In line 3 of claim 2, it is believed the word “integral” should be changed to --integrally--. In lines 3-4 of claim 9, it is believed the phrase “vehicle’s windshield” should be changed to remove the possessive language, such as --a windshield of the vehicle--. In lines 24-25 of claim 9, it is believed the phrase “vehicle’s windshield washer reservoir” should be changed to remove the possessive language, such as --a windshield washer reservoir of the vehicle--. Appropriate correction is required. 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 1-14 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. Claim 1 recites the limitation "the base" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the width" in line 4. There is insufficient antecedent basis for this limitation in the claim. In line 6 of claim 1, the phrase “the opposite side” is confusing and unclear. It is not clear if the limitation refers to an opposite side of the vehicle or an opposite side of the windshield or an opposite side of the windshield cowling. When applying prior art, Examiner interprets this limitation to mean “an opposite side of the vehicle in the width direction. Claim 1 recites the limitation "the elevation" in line 9. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the lower chamber" in line 16. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the base" in line 20. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the base" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the width" in line 4. There is insufficient antecedent basis for this limitation in the claim. In line 6 of claim 9, the phrase “the opposite side” is confusing and unclear. It is not clear if the limitation refers to an opposite side of the vehicle or an opposite side of the windshield or an opposite side of the windshield cowling. When applying prior art, Examiner interprets this limitation to mean “an opposite side of the vehicle in the width direction. Claim 9 recites the limitation "the base wall elevation" in line 9. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the inlet" in line 19. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the base" in line 23. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the conditioned fluid" in line 24. There is insufficient antecedent basis for this limitation in the claim. 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.
