Office Action

§112 §DP
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 . Information Disclosure Statement The information disclosure statement filed October 31, 2023 fails to comply with 37 CFR 1.98(a)(3)(i) because it does not include a concise explanation of the relevance, as it is presently understood by the individual designated in 37 CFR 1.56(c) most knowledgeable about the content of the information, of each reference listed that is not in the English language. It has been placed in the application file, but the information referred to therein has not been considered. PTO-1449 indicates that a translation is included. Reference KR-10-2409287 contains no translation. 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 and 2 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 enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. The claims are directed to “[a] fire suppression tank of an electric vehicle charging station.” Claim 1 recites the limitation “wherein a battery of the electric vehicle is submerged to be stabilized by filling the tank with water.” Currently virtually every electric vehicle utilizes lithium batteries. Water is incapable of suppressing, extinguishing or stabilizing a lithium battery fire. Claims 1 and 2 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for the inflated air injection type multi-wall tube surrounding the vehicle on four sides, does not reasonably provide enablement for the inflated air injection type multi-wall tube surrounding the vehicle on all sides, i.e., the all sides to include the top side and the bottom side. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention commensurate in scope with these claims. A reasonable reading of the specification teaches the inflated air injection type multi-wall tube surrounding the vehicle on four sides: front, back, left and right. The specification does not teach a top side or a bottom side. 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 and 2 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 claims are generally narrative and indefinite, failing to conform with current U.S. practice. They appear to be a literal translation into English from a foreign document and are replete with grammatical and idiomatic errors. Claim 1 recites the limitation “a quadrilateral frame-shaped tube storage part” in line 3. It is uncertain what shape is defined by “a quadrilateral frame-shaped.” Claim 1 recites the limitation “an entering vehicle” in line 4. The preamble of the claim is directed to a subcombination of a fire suppression tank of an electric vehicle charging station. Yet the body of the claim is directed to the combination of a fire suppression tank of an electric vehicle charging station and an entering vehicle. The scope of the body of the claim exceeds the scope of the preamble. Claim 1 recites the limitation “an air injection type multi-wall tube” in line 7. The recitation “type” renders the claim indefinite. MPEP 2173.05(b).III.E. Claim 1 recites the limitation “an upper opening of the storage body is opened or closed by an opening/closing cover” in lines 9-10. The claim fails to recite structure that opens and closes the opening/closing cover. The structure recited by the claim is not commensurate in scope with the function recited by the claim. Claim 1 recites the limitation “as air is injected into the air injection type multi-wall tube” in lines 10-11. The claim fails to recite structure that injects air. The structure recited by the claim is not commensurate in scope with the function recited by the claim. Claim 1 recites the limitation "the electric vehicle" in line 14. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation “to be stabilized” in line 14. The interpretation of stabilized requires a subjective determination. What may be constitute stabilized to one of ordinary skill in the art may not constitute stabilized to another of ordinary skill in the art. Claim 1 recites the limitation “by filling the tank with water” in lines 14-15. The claim fails to recite structure that fills the tank with water. The structure recited by the claim is not commensurate in scope with the function recited by the claim. Claim 2 recites the limitation of a shape enclosed in quotes in line 3. It is uncertain what shape is being defined. The shape in the claim is a two dimensional shape. Is it a shape of a cross section of the opening/closing cover? If so, which cross section. Applicant should not misconstrue the lack of art rejection as an indication of allowable subject matter. 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 and 2 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 and 2 of copending Application No. 18/385,654 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the claims 1 and 2 of the reference application fully disclose the currently claimed invention. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
