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 . The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim Objections Claims 10, 36, and 37 are objected to because of the following informalities: Claim 10 recites “annual” and should be “ annular”. Claim 36 recites “annual” and should be “ annular”. Claim 37 recites “annual” and should be “ annular”. Claim Rejections - 35 USC § 112 Claims 36 and 37 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 36 recites “at least one radially outwardly extending portion” and “the radially outwardly extending annular portion” which is unclear if claim 36 intended to only have one radially outwardly extending portion or one or more radially outwardly extending portion. For examination purposes, the limitation will be interpreted as “the at least one radially outwardly extending Claim 37 is unclear for the same reasons above for claim 36. 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. Claims 10, 14, 22, 34, 36-37, and 39 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kim (KR 2014017902 A).

Claim Rejections - 35 USC § 103 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. Claims 15 and 40 are rejected under 35 U.S.C. 103 as being unpatentable over Kim (KR 2014017902 A). In regard to claim 15, Kim discloses the tubing connection according to claim 10, wherein: at least one of (i) the tubular element or (ii) the fitting comprises at least one metallic material, wherein the at least one metallic material comprises one or more of: copper, iron, steel, stainless steel, brass, cast material or forged material (See English translation of the abstract which discloses the invention can be made of stainless steel) Kim does not expressly disclose one or more of (a) carbon material or (b) at least one plastic material, and the at least one plastic material comprises one or more of polymethylmethacrylate, polycarbonate, polyvinyl chloride, glass fiber or reinforced plastic. 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. In re Leshin, 125 USPQ 416. 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 material of the tubular element and/or the fitting of Kim to be made of a known material such as stainless steel with carbon material with a reasonable expectation of success in order to have the advantage of a stainless steel material of increased corrosion resistance, high and low temperature resistance, improved strength, improved weldability, improved formability, or controlling magnetism as disclosed at https://www.unifiedalloys.com/blog/what-is-stainless-steel. In regard to claim 40, Kim discloses the apparatus of claim 39, wherein: the at least one radially outwardly extending portion comprises a first radially outwardly extending portion forming a first annular recess (Fig. 2, at 5 defines a first annular recess); the at least one sealing element comprises a first sealing element arranged in the first annular recess (Fig. 2, sealing element at 6 in 5). Kim does not expressly disclose a second radially outwardly portion forming a second annular recess and a second sealing element arranged in the second annular recess. It has been held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). See MPEP § 2144.04(VI)(B). In this case, 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 Kim to include a second radially outwardly portion forming a second annular recess and a second sealing element arranged in the second annular recess with a reasonable expectation of success in order to have the advantage of a stronger seal connection with two seals instead of one. Additionally, applicant’s specification lacks any description of any unexpected results or non-obviousness of a second seal and the drawings do not show any second seal. Therefore, the claimed second seal lacks criticality and the crux of applicant’s invention with regard to the at least one radially outwardly extending portion is to have at least one seal. Claim 35 and 38 are rejected under 35 U.S.C. 103 as being unpatentable over Kim (KR 2014017902 A) in view of Amplett (US 3,767,211). In regard to claims 35 and 38, Kim discloses the tubing connection according to claims 10 and 34, but does not expressly disclose further comprising at least one receptacle including at least one sealant, the receptacle being configured to rupture when the diameter of at least a part of the first connection element is reduced thereby releasing the at least one sealant contained therein. In the related field of systems utilizing gaskets, Amplett teaches a gasket having at least one receptacle including at least one sealant, the receptacle being configured to rupture when a pressure is applied to the gasket (In 1:60-68 to 2:1-25 discloses the invention relates to gasket with pressure-rupturable microcapsules on the surface of the gasket which upon a pressure, the microcapsules rupture to release a sealing liquid composition) in order to have the advantage of an improved gasket seal (In 1:60-68 to 2:1-25 discloses the pressure-rupturable microcapsules provides an improved gasket seal since connection with gaskets may have irregular surfaces that are not sealed by only the gasket or connections with gaskets that lose tension due to gasket relaxation). 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 at least one sealing element of Kim to include at least one receptacle including at least one sealant, the receptacle being configured to rupture when the diameter of at least a part of the first connection element is reduced thereby releasing the at least one sealant contained therein with a reasonable expectation of success in order to have the advantage of an improved gasket seal as taught by Amplett. Claims 15 and 40 are rejected under 35 U.S.C. 103 as being unpatentable over Salehi-Bakhtiari (US 2013/0049361 A1). In regard to claim 15, Salehi-Bakhtiari discloses the tubing connection according to claim 10, wherein: at least one of (i) the tubular element or (ii) the fitting comprises at least one metallic material (In [0077] discloses metal) but does not expressly disclose and one or more of (a) carbon material or (b) at least one plastic material, the at least one metallic material comprises one or more of: copper, iron, steel, stainless steel, brass, cast material or forged material, and the at least one plastic material comprises one or more of polymethylmethacrylate, polycarbonate, polyvinyl chloride, glass fiber or reinforced plastic. 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. In re Leshin, 125 USPQ 416. 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 material of the tubular element and/or the fitting of Salehi-Bakhtiari to be made of a known material such as stainless steel with carbon material with a reasonable expectation of success in order to have the advantage of a stainless steel material of increased corrosion resistance, high and low temperature resistance, improved strength, improved weldability, improved formability, or controlling magnetism as disclosed at https://www.unifiedalloys.com/blog/what-is-stainless-steel. In regard to claim 40, Salehi-Bakhtiari discloses the apparatus of claim 39, wherein: the at least one radially outwardly extending portion comprises a first radially outwardly extending portion forming a first annular recess (Fig. 5, at 11 defines a first annular recess); the at least one sealing element comprises a first sealing element arranged in the first annular recess (Fig. 2, sealing element at 6 in 5). Salehi-Bakhtiari does not expressly disclose a second radially outwardly portion forming a second annular recess and a second sealing element arranged in the second annular recess. It has been held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). See MPEP § 2144.04(VI)(B). In this case, 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 Salehi-Bakhtiari to include a second radially outwardly portion forming a second annular recess and a second sealing element arranged in the second annular recess with a reasonable expectation of success in order to have the advantage of a stronger seal connection with two seals instead of one. Additionally, applicant’s specification lacks any description of any unexpected results or non-obviousness of a second seal and the drawings do not show any second seal. Therefore, the claimed second seal lacks criticality and the crux of applicant’s invention with regard to the at least one radially outwardly extending portion is to have at least one seal. Response to Arguments Applicant's arguments filed 09/04/2025 have been fully considered but they are not persuasive. In response to applicant’s arguments that the Examiner interpreted the hook and gripping element of Kim as merely different portions of a single structural element and the alleged gripping element is not situated at a terminus of any annular recess, however, the Examiner respectfully disagree because the interpretation of the hook and gripping element being different portions of a single structural element is a reasonably interpretation in light of applicant’s invention shown in Fig. 3 where the hook at 21’ and the gripping element 31’ are different portions of a single structural element of the fitting. Therefore, a gripping element can be reasonably interpreted as a portion of a fitting. See the updated rejection above such that an alternative interpretation of Kim discloses at least a gripping element that extends from a terminus of the annular recess and is axially spaced apart from the hook. Therefore, applicant’s arguments are unpersuasive and contradictory. With regard to Salehi-Bakhtiari, see the updated rejection above such that an alternative interpretation of Kim discloses at least a gripping element that extends from a terminus of the annular recess and is axially spaced apart from the hook. Therefore, the applicant’s arguments are unpersuasive. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
