Office Action

§102 §103 §112
DETAILED ACTION Claims 1-12 are pending. This action is in response to the amendment filed 12/10/2025. 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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 1/20/2026 has been entered. Response to Arguments Applicant’s arguments with respect to the pending claim(s) have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Drawings 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 limitations in claim 11 (no reference numerals shown for the structural recited features) must be shown or the feature(s) canceled from the claim(s). 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. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: in claim 11, the limitations, the outer wall of the tank housing has a protruding wall that protrudes therefrom in a direction away from the interior space of the tank housing and that surrounds a portion of the cavity, and wherein when the second electronics housing part is connected to the first electronics housing part, a side wall of the second electronics housing part overlaps with and surrounds an outer periphery of the protruding wall, with the seal being positioned between the side wall of the second electronics housing part and the outer periphery of the protruding wall, are not supported in the specification, however, appear to be in Figure 5, and therefore may be added to the specification as long as no new matter is added. Claim Objections Applicant’s amendment overcomes the prior objection. Claim Rejections - 35 USC § 112 Applicant’s amendment overcomes the prior objection. Claim Rejections - 35 USC § 102 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 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. Claim(s) 1-2 are rejected under 35 U.S.C. 102a1 as being anticipated by Virtanen et al. (US 3433072).

Regarding "for a coolant conducting system of a motor vehicle", and “for storing a coolant for the coolant conducting system”, a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. PNG media_image1.png 1072 724 media_image1.png Greyscale Regarding claim 2, Virtanen et al. disclose the tank housing is multipart (as seen in fig. 1, the housing has inherent sides, and, bottom and that 8 is disclosed as the cover) tank housing that includes a tank cover (8, col. 2, lns. 34-36), and wherein the outer wall (of 8) that is the first electronics housing part is the tank cover of the tank housing. Claim(s) 1 and 12 are rejected under 35 U.S.C. 102a1 as being anticipated by Yamamoto et al. (US 7064560). Regarding claim 1, Yamamoto et al. disclose a coolant tank (the tank LT, see Fig. 5-8) “for a coolant conducting system of a motor vehicle” (intended use, see also , col. 12, lns 32-38, col. 15,lns. 4-7 “water”), the coolant tank comprising: A tank sensor (100), tank electronics (163, col. 14,ln.53-61); a seal (see fig. 6, the o-ring seal shown un-numbered between LT and 121); a tank housing (LT) with an outer wall (the outer wall of LT that connects to 121) and an interior space (the space within LT) that is arranged in the tank housing “for storing a coolant for the coolant conducting system”, the outer wall being a first electronics housing part for the tank electronics (the outer wall of LT connects with 121 and is therefore a first electronics housing part for the tank electronics since it mates the connector 121 to the tank LT), and, a second electronics housing part (121), which is an electronics housing cover for the tank electronics (163), wherein when the second electronics housing part is connected to the first electronics housing part and the second electronics housing part form a cavity (the space within 121) that encloses the tank electronics so as to be sealed against environmental influences, directly or indirectly via the seal (as shown in Figure 6), and wherein the first electronics housing part, that is the outer wall of the tank housing, provides a barrier (when viewing a line/plane through the wall thickness of LT to 121 and to 163,see Fig. 6) between the tank electronics and the interior space of the tank housing, such that prior to the second electronics housing part being connected to the first electronics housing part, the tank electronics are sealed from the interior space of the tank housing by the first electronics housing part (as shown in Figure 6, the thickness of the wall LT provides the barrier as shown and therefore, the limitations of, “the first electronics housing part, that is the outer wall of the tank housing, provides a barrier between the tank electronics and the interior space of the tank housing, such that prior to the second electronics housing part being connected to the first electronics housing part, the tank electronics are sealed from the interior space of the tank housing by the first electronics housing part” are met), and wherein the tank sensor (111,181 ,see Fig. 6-8) extends through the outer wall of the tank housing and connects to the tank electronics, such that a first portion (113,111,181,171,131,180 within LT, see Fig. 6,7A,8) of the tank sensor is provided in the cavity formed between the first electronics housing part and the second electronics housing part, and a second portion (141,143,145,155,132,163, see Fig. 8) of the tank sensor is provided in the interior space of the tank housing. Regarding "for a coolant conducting system of a motor vehicle", and “for storing a coolant for the coolant conducting system”, a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. Regarding claim 12, Yamamoto et al. disclose the tank electronics include a printed circuit board (163), and wherein the first portion of the tank sensor is connected directly to the printed circuit board (as shown in Fig. 5-8). PNG media_image2.png 1365 798 media_image2.png Greyscale 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. 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(s) 3 and 4 are rejected under 35 U.S.C. 103 as being unpatentable over Virtanen et al. (US 3433072) in view of Getman et al. (US 5730025). Regarding claim 3, Virtanen et al. disclose all of the features of the claimed invention although are silent to having, the outer wall that is the first electronics housing part is inclined, at least in a receptacle area for the tank electronics, such that liquid dripping onto the tank housing from above runs off the aforementioned receptacle area as a result of gravity. Getman et al. disclose the outer wall that is the first electronics housing part is inclined (as shown in figure 3 the wall is vertical and therefore considered as being inclined in a broadest reasonable interpretation), at least in a receptacle area (the area of wall 12 as shown in figure 3 where 13 is located) for the tank electronics, such that liquid dripping onto the tank housing from above runs off the aforementioned receptacle area as a result of gravity (liquid that contacts this outer wall region will runoff this area). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the sensor of Virtanen et al., being located in an inclined wall as taught by Getman et al., to have, the outer wall that is the first electronics housing part is inclined, at least in a receptacle area for the tank electronics, such that liquid dripping onto the tank housing from above runs off the aforementioned receptacle area as a result of gravity, since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. Regarding claim 4, Virtanen et al. disclose all of the features of the claimed invention, including, the tank housing is a multipart tank housing (as seen in fig. 1, the housing has the top 8 and inherently a side(s) and a bottom and therefore considered as a multipart tank housing), although are silent to having, all parts of the tank housing are each designed as a one-piece plastic part are each one-piece plastic. Getman et al. disclose the tank housing is a multipart tank housing (as seen in fig. 1, the housing has 4 sides and therefore considered as a multipart tank housing), and wherein all parts of the tank housing are each designed as a one-piece plastic part (col.4, lns. 58-61) are each one-piece plastic. When the reference is a utility patent, it does not matter that the feature shown is unintended or unexplained in the specification. The drawings must be evaluated for what they reasonably disclose and suggest to one of ordinary skill in the art. In re Aslanian, 590 F.2d 911, 200 USPQ 500 (CCPA 1979). See MPEP 2125. Here, the drawings clearly show the tank housing parts are each one part in the cited reference. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to substitute a plastic material from Getman et al. for the material in Virtanen et al., since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice, as an example for the proper material compatibility with the fluid being used in the system. In re Leshin, 227 F.2d 197, 125 USPQ 416 (CCPA 1960). Claim(s) 5 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over Carney et al. (US 7343884) in view of Virtanen et al. (US 3433072). Regarding claim 5, Carney et al. disclose a coolant conducting system for a motor vehicle (see Fig. 1) with multiple coolant circuits, a coolant tank (208); and at least two coolant passages (210/154 and the passage to pump 206) that deliver a coolant from the coolant tank into at least one coolant circuit (within 140,142), although are silent to having, wherein the coolant tank comprises, the tank electronics to control the coolant conducting system, a tank sensor; a seal; a tank housing with an outer wall and an interior space that is arranged in the tank housing for storing the coolant for the coolant conducting system, the outer wall being a first electronics housing part for the tank electronics: and a second electronics housing part, which is an electronics housing cover for the tank electronics, wherein when the second electronics housing part is connected to the first electronics housing part, the first electronics housing part and the second electronics housing part form a cavity therebetween that encloses the tank electronics so as to be sealed against environmental influences, directly or indirectly via the seal, wherein the first electronics housing part, that is the outer wall of the tank housing, provides a barrier between the tank electronics and the interior space of the tank housing, such that prior to the second electronics housing part being connected to the first electronics housing part, the tank electronics are sealed from the interior space of the tank housing by the first electronics housing part and wherein the tank sensor extends through the outer wall of the tank housing and connects to the tank electronics, such that a first portion of the tank sensor is provided in the cavity formed between the first electronics housing part and the second electronics housing part, and a second portion of the tank sensor is provided in the interior space of the tank housing. Virtanen et al. teach the use of a tank sensor (2-5), tank electronics (transmitter, transistor, resistances, col. 2, lns. 37-40); a seal (see fig. 1, the rectangular seal shown un-numbered between 7 and 8); a tank housing (8) with an outer wall (the outer wall of 8 that connects to 7) and an interior space (the space within 8) that is arranged in the tank housing “for storing a coolant for the coolant conducting system”, the outer wall being a first electronics housing part for the tank electronics (the outer wall connects with 7 and 9 and is therefore a first electronics housing part for the tank electronics since it mates the connector 7 to the tank 8), and, a second electronics housing part (9), which is an electronics housing cover for the tank electronics (transmitter, transistor, resistances, col. 2, lns. 37-40), wherein when the second electronics housing part is connected to the first electronics housing part and the second electronics housing part form a cavity (the space within 9) that encloses the tank electronics so as to be sealed against environmental influences, directly or indirectly via the seal (as shown in Figure 1), and wherein the first electronics housing part, that is the outer wall of the tank housing, provides a barrier (the wall thickness of 8,see Fig. 1) between the tank electronics and the interior space of the tank housing, such that prior to the second electronics housing part being connected to the first electronics housing part, the tank electronics are sealed from the interior space of the tank housing by the first electronics housing part (as shown in Figure 1, the thickness of the wall 8 provides the barrier as shown and therefore, the limitations of, “the first electronics housing part, that is the outer wall of the tank housing, provides a barrier between the tank electronics and the interior space of the tank housing, such that prior to the second electronics housing part being connected to the first electronics housing part, the tank electronics are sealed from the interior space of the tank housing by the first electronics housing part” are met), and wherein the tank sensor (3,4,5) extends through the outer wall of the tank housing and connects to the tank electronics, such that a first portion (5, within 9, see Fig. 1) of the tank sensor is provided in the cavity formed between the first electronics housing part and the second electronics housing part, and a second portion (3-5 within 8, see Fig. 1,2) of the tank sensor is provided in the interior space of the tank housing.

(US 5627523). Regarding claims 8 and 9, Carney et al. and Virtanen et al. disclose all of the features of the claimed invention, although, are silent to having, the tank electronics are designed and configured such that all control tasks of the coolant conducting system are performed entirely via the tank electronics, and, the tank electronics are designed and configured such that a processing or preprocessing of signals present at the tank electronics are performed by the tank electronics. Besprozvanny et al. disclose a level sensor that teach that the tank electronics are designed and configured such that all control tasks of the coolant conducting system are performed entirely via the tank electronics (col. 3, lns. 52-65,col.5, lns. 13-21), and, the tank electronics are designed and configured such that a processing or preprocessing of signals present at the tank electronics are performed by the tank electronics (col. 6, lns. 1-17). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ the electronics as taught Besprozvanny et al. into the combined device of Carney et al. and Virtanen et al. to have the tank electronics are designed and configured such that all control tasks of the coolant conducting system are performed entirely via the tank electronics, and, the tank electronics are designed and configured such that a processing or preprocessing of signals present at the tank electronics are performed by the tank electronics, in order to provide a highly reliable level sensor, which also detects faulty sensor switches for repair or replacement (Besprozvanny et al. , col. 2, lns 30-39). Allowable Subject Matter Claim 11 is 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. None of the prior art of record discloses or renders as obvious, “the outer wall of the tank housing has a protruding wall that protrudes therefrom in a direction away from the interior space of the tank housing and that surrounds a portion of the cavity, and wherein when the second electronics housing part is connected to the first electronics housing part, a side wall of the second electronics housing part overlaps with and surrounds an outer periphery of the protruding wall, with the seal being positioned between the side wall of the second electronics housing part and the outer periphery of the protruding wall”, in combination with the claim 10 from which it depends in its entirety. The patent to Blankenship (US 4827242) discloses the closest prior art, but is not seen as having, a side wall of the second electronics housing part overlaps with and surrounds an outer periphery of the protruding wall. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
