Office Action

§102 §103 §112
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 1-3, 5, 8, 10, 12, and 16 are objected to because of the following informalities: Claim 1 recites “a plurality of connecting assemblies, each plurality of connecting assemblies” and should be “a plurality of connecting assemblies, each connecting assembly Claim 2 recites “wherein the locking component includes a first locking component and a second locking component, and wherein the receiving component includes a first receiving component and a second receiving component” and should be “wherein the plurality of connecting assemblies define two connecting assemblies that , , and a second receiving component” because the connecting assemblies respectively include a locking component and a receiving component and to avoid any confusion that a single locking component define two locking components. Claim 2 recites many limitations separated by commas, however, should include “wherein” and/or semi-colons to avoid ambiguity of what limitations are grouped together and what intended to begin a new clause. Claim 3 recites many limitations separated by commas, however, should include “wherein” and/or semi-colons to avoid ambiguity of what limitations are grouped together and what intended to begin a new clause. Claim 5 recites “a second side cover, the first inner wall” and should be “a second side cover, wherein the first inner wall” to avoid ambiguity of what limitations are grouped together and what are intended to begin a new clause. Claim 8 should include “wherein” or semi-colons at least between “a fixing end, the fixing end” for similar reasons above for claim 5. Claim 10 should include “wherein” or semi-colons at least between “the second receiving part, the first receiving part” and “the first cavity, the second receiving part” for similar reasons above for claim 5. Claim 12 should include “wherein” or semi-colons at least between “the first wall, the third extension” for similar reasons above for claim 5. Claim 16 should include “wherein” or semi-colons at least between “the fixing part, the first line perimeter edge” for similar reasons above for claim 5. Accordingly, claims 2, 5, 8, 10, 12, and 16 appear to have many limitations separated by commas, however, should include “wherein” and/or semi-colons to break limitations that are not grouped together. 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 4 and 15-16 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 4 recites “the second groove is between the second groove and the first liquid line” which is unclear how the second groove is between itself and the first liquid line and is unclear of what applicant’s intent is to be between the second groove and the first liquid line. For examination purposes, the limitation will be interpreted as “the third sealant member is between the second groove and the first liquid line” because the third sealant member is radially between the second groove and the first liquid line as shown in Fig. 4 of applicant’s drawings. Claim 15 recites “the inner surfaces of the chamber” which is unclear if this is the same or different from the inner surfaces of the housing recited in claim 11. For examination purposes, the limitation will be interpreted as “the inner surfaces of the housing” to be consistent with claim 11. All dependent claims of these claims are rejected under 112th second paragraph by virtue of their dependency. Thus, claim 16 is rejected under 112th second paragraph. 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 (i.e., changing from AIA to pre-AIA ) 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 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Jackowski (US 5,568,946) in view of Nickel (DE 202011003140 U1). Jackowski discloses the liquid coupler of claim 3, but does not expressly disclose further comprising a third sealant member, and wherein the second adaptor component further includes a second groove, the third sealant member sealably positioned in the second groove, when the second adaptor component is fixed to the second liquid line and the first adaptor component is locked to the second adaptor component, the third sealant member is between the second groove and the first liquid line. In the related field of liquid couplers, Nickel teaches a sealant member (Fig. 1, sealant member 15), and wherein a second adaptor component further includes a groove (Fig. 1, the part at 3 defines a second adaptor having a groove at 14), the sealant member sealably positioned in the groove (Fig. 1, 15 positioned in 14), when the second adaptor component is fixed to a second liquid line (Fig. 1, part 3 is fixed to a second liquid line at 18) and a first adaptor component is locked to the second adaptor component (Fig. 1, the part at 19 can be a first adaptor component locked to 3 as shown), the sealant member is between the groove and a first liquid line (Fig. 1, first liquid line at 4 and 15 is between 14 and the first liquid line) in order to have the advantage of a known and reliable seal connection between a male and female tubular connection by an O-ring gasket in a groove that contacts an outer surface of the male tubular component. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the liquid coupler of Jackowski to include a third sealant member, and wherein the second adaptor component further includes a second groove, the third sealant member sealably positioned in the second groove, when the second adaptor component is fixed to the second liquid line and the first adaptor component is locked to the second adaptor component, the third sealant member is between the second groove and the first liquid line with a reasonable expectation of success in order to have the advantage of a known and reliable seal connection between a male and female tubular connection by an O-ring gasket in a groove that contacts an outer surface of the male tubular component as taught by Nickel. Additionally, Jackowski in view Nickel would reasonably suggest to a person of ordinary skill in the art to include more than one seal in the liquid coupler to increase the sealing reliability of the liquid coupler in case of a first seal were to fail, a second or more seals can maintain the seal within the pipe coupler. Claims 13 is rejected under 35 U.S.C. 103 as being unpatentable over Jackowski (US 5,568,946) in view of Mao (US 10,823,321 B2). Jackoawski discloses the liquid coupler of claim 11, but does not expressly disclose wherein the connection part includes male threads, and wherein the second liquid line includes female threads, the connection part fixes the second adaptor component to the second liquid line via rotation. In the related field of pipe couplers, Mao discloses wherein a connection part includes barbs or threads for connecting to a liquid line having complementary threads and the threads of the connection part fixes to the liquid line via rotation (Fig. 6 shows a connection part at 43 having threads and in the embodiment shown in Fig. 8, the connection part can be a mechanically equivalent connection such as threads at 442 to connect to another liquid line having complementary threads). Additionally, threaded connections are well known that provide at least advantages of easy installation, no welding required, lower installation costs, and a strong and reliable connection as disclosed at https://www.pipesandfittings.com/advantages-of-threaded-pipe-fittings.html. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have substituted the barbed connection between the connection part and second liquid line of Jackowski for male threads on the connection part and for female threads on the second liquid line with a reasonable expectation of success in order to have the advantage of easy installation, no welding required, lower installation costs, and a strong and reliable connection as taught by Mao. See MPEP 2143(I)(B) with regard to simple substitution of one known element for another to obtain predictable results. Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Jackowski (US 5,568,946) in view of Mao (US 10,823,321 B2) and further in view of Dirneder (US 2020/0149665 A1). Jackowski and Mao disclose the liquid coupler of claim 13, but do not expressly disclose further comprising a first sealant member, and wherein the second adaptor component further includes a first groove, the first groove between the housing and the connection part, the first sealant member sealably positioned in the first groove, when the second adaptor component is fixed to the second liquid line, the first sealant member is between a second line perimeter edge of the second liquid line and the first groove. In the related field of threaded connections, Dirneder teaches a first sealant member (Fig. 1, a first sealant member at 56), and wherein a second adaptor component further includes a first groove (Fig. 1, part 12 has a first groove at 50), the first groove between a housing and a connection part (Fig. 1, 50 is axially between a connection part at 16 and a housing portion at 18), the first sealant member sealably positioned in the first groove (Fig. 1, 56 is positioned in 50), when the second adaptor component is fixed to a second liquid line, the first sealant member is between a second line perimeter edge of the second liquid line and the first groove (Fig. 1, a second liquid line with female threads would be threaded onto 16 and 56 would be axially between a perimeter edge at the axial end opening of the second liquid line and the groove 50 similar to applicant’s invention) in order to have at least the advantage of a known and reliable sealing connection for a threaded connection (In [0026-0027] discloses the seal 56 provides a reliable seal for the threaded connection at 16). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the connection at the connection part of Jackowski and Mao to include a first sealant member, and wherein the second adaptor component further includes a first groove, the first groove between the housing and the connection part, the first sealant member sealably positioned in the first groove, when the second adaptor component is fixed to the second liquid line, the first sealant member is between a second line perimeter edge of the second liquid line and the first groove with a reasonable expectation of success in order to have the advantage of a known and reliable sealing connection for a threaded connection as taught by Dirneder. Claims 15 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Jackowski (US 5,568,946) in view of Le Quere Philippe (WO 2010052386 A1). In regard to claim 15, Jackowski discloses wherein the chamber includes an inner receiving ledge, the inner receiving ledge protrudes from the inner surfaces of the housing (Fig. 4, shoulder of 52 adjacent to the axial end of the first liquid line at 92 which is in the chamber and defines a inner receiving ledge that protrudes from the inner surfaces of the chamber similar to applicant’s invention), but does not expressly disclose the liquid coupler of claim 11, further comprising a second sealant member, and wherein the second sealant member positioned on the inner receiving ledge, the second sealant member sealably positioned between the inner receiving ledge and a first line perimeter edge of the first liquid line, and wherein the second sealant member is configured to deform and fix the first liquid line to the second adaptor component. In the related field of pipe couplers, Le Quere Philippe teaches a sealant member positioned on an inner receiving ledge and a first line perimeter edge of a first liquid line, and wherein the sealant member is configured to deform and fix the first liquid line in order to have at least the advantage of a known and reliable sealing connection between an end of a liquid line and an inner receiving ledge (Figs. 1-15 show various embodiments of a sealant member 6 positioned against an inner receiving ledge at the part 2 and against a first line perimeter edge of a first liquid line 4 such that the sealant member 6 is configured to deform and fix the first liquid line in order to perform a sealing connection). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the inner receiving ledge of Jackowski to include a second sealant member, and wherein the second sealant member positioned on the inner receiving ledge, the second sealant member sealably positioned between the inner receiving ledge and a first line perimeter edge of the first liquid line, and wherein the second sealant member is configured to deform and fix the first liquid line to the second adaptor component with a reasonable expectation of success in order to have the advantage of a known and reliable sealing connection between an end of a liquid line and an inner receiving ledge as taught by Le Quere Philippe. Additionally, Jackowski in view Le Quere Philippe would reasonably suggest to a person of ordinary skill in the art to include more than one seal in the liquid coupler to increase the sealing reliability of the liquid coupler in case of a first seal were to fail, a second or more seals can maintain the seal within the pipe coupler. In regard to claim 16, Jackowski and Le Quere Philippe disclose the liquid coupler of claim 15, and Le Quere Philippe further discloses wherein the second sealant member includes an adaptor rim and a fixing part (Fig. 11, adaptor rim at 19.1 and a fixing part at 10), the adaptor rim surrounds the fixing part (Fig. 11, 19.1 surrounds 10), wherein the first line perimeter edge of the first liquid line is positioned on the adaptor rim (Fig. 11, the first line perimeter edge at 12 is positioned on the adaptor rim similar to applicant’s invention), the fixing part configured to enable the second sealant member to grip the first liquid line (Fig. 11, 10 is configured to enable the sealant member to grip 4 as shown and similar to applicant’s invention such that the fixing part grips an inner bore surface of the first liquid line. See claim 15 above for the same reasons to combine Jackowski and Le Quere Philippe.). Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Jackowski (US 5,568,946). Jackowski discloses the liquid coupler of claim 1, wherein the first liquid line includes a round liquid line and the second liquid line includes a round liquid line (Figs. 2 and 4, the first and second liquid lines include at least round liquid lines as shown). Jackowski does not expressly disclose the first liquid line includes a square line. However, a person of ordinary skill in the art would at least reasonably have round pipes transition to square lines because having square lines provide at least the advantage of increased load-bearing capacity, improved structural integrity, and desired fluid flow. See at least https://www.youtube.com/watch?v=w9rHHe-XnLw, https://www.spiralmfg.com/high-pressure-rectangular-round-transitions/, and https://engineerexcel.com/square-pipe-vs-round-pipe-flow/ such that square and round pipes are known and transitions from round to square is known and within knowledge of a person of ordinary skill in the art. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the first liquid line of Jackowski to include at least a square transition line with a reasonable expectation of success in order to have the advantage of a known and reliable shape for a fluid line, increased load-bearing capacity, improved structural integrity, and desired fluid flow. Allowable Subject Matter Claims 7 and 12 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 following is an examiner’s statement of reasons for allowance of claims 7 and 12: In regard to claim 7, Jackowski discloses the liquid coupler of claim 5, but does not show or suggest wherein the first inner wall includes a first wall perimeter edge and a second wall perimeter edge, and the second inner wall includes a third wall perimeter edge and a fourth wall perimeter edge, and wherein, the first side cover includes a third first side perimeter edge and a third second side perimeter edge, and the second side cover includes a fourth first side perimeter edge and a fourth second side perimeter edge, the first wall perimeter edge coupled to the third first side perimeter edge, the second wall perimeter edge coupled to the fourth first side perimeter edge, the third wall perimeter edge coupled to the third second side perimeter edge, the fourth wall perimeter edge coupled to the fourth second side perimeter edge. It would not have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified Jackowski to include wherein the first inner wall includes a first wall perimeter edge and a second wall perimeter edge, and the second inner wall includes a third wall perimeter edge and a fourth wall perimeter edge, and wherein, the first side cover includes a third first side perimeter edge and a third second side perimeter edge, and the second side cover includes a fourth first side perimeter edge and a fourth second side perimeter edge, the first wall perimeter edge coupled to the third first side perimeter edge, the second wall perimeter edge coupled to the fourth first side perimeter edge, the third wall perimeter edge coupled to the third second side perimeter edge, the fourth wall perimeter edge coupled to the fourth second side perimeter edge with a reasonable expectation of success because such a modification would require hindsight reasoning and reconstruction. In regard to claim 12, Jackowski discloses the liquid coupler of claim 11, but does not show or suggest wherein the housing includes a first wall, a second wall, a third wall, and a fourth wall, wherein the first extension part and the second extension part respectively protrude from the first wall, wherein the third extension part and the fourth extension part respectively protrude from the second wall. It would not have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified Jackowski to include wherein the housing includes a first wall, a second wall, a third wall, and a fourth wall, wherein the first extension part and the second extension part respectively protrude from the first wall, wherein the third extension part and the fourth extension part respectively protrude from the second wall with a reasonable expectation of success because such a modification would require hindsight reasoning and reconstruction. 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.” Conclusion The following prior arts made of record and not relied upon are considered pertinent to applicant's disclosure: Wicks et al. (US 7,878,553 B2), Tesluk et al. (US 7,490,620), Kulevsky (US 5,897,142), Gu et al. (US 12,110,998 B2), Manly (US 3,245,703), Godeau (US 5,228,724), and Lai (US 2009/0200796 A1) disclose a snap-fit connection between two adaptors by a hook and cavity to join two pipes together similar to the applicant’s invention.
