Office Action

§102 §103
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 Status Claims 1-4, 6-10, 12 and 13 are pending. Examiner acknowledges Applicant’s amendments to claims 1, 4, 6, 7, 10 and 13 and the cancelation of claims 5 and 11. Response to Arguments Applicant’s arguments with respect to claim(s) 1-4, 6-10, 12 and 13 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 were received on 5/27/25. These drawings are not acceptable to Examiner. See the drawing objections set forth below. The drawings are objected to because: Figure 13 – the second clip is not shown as described in paragraph 34 of the specification. Figure 13 – the multiple o-rings look like a singular o-ring at 608. 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 disclosure is objected to because of the following informalities: Paragraph 34 – the second clip is not shown in Figure 13 as described in paragraph 34 of the specification. Correction is required. Claim Objections Claim 1 is objected to because of the following informalities: Lines 5 and 7 – add --at least one-- between “the” and “o-ring”. Correction is required. Claim 6 is objected to because of the following informalities: it is not clear what changes were made to claim 6 which has a claim status identifier “(Currently amended)”. It does not appear that any changes were made to claim 6. Correction is required. Claim 7 is objected to because of the following informalities: Lines 7 and 8 - add --at least one-- between “the” and “o-ring”. Line 8 – add a comma before “the spigot indentation”. Correction is required. Claim 10 is objected to because of the following informalities: Line 1 – add --two-- before “o-rings”. Correction is required. 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. Claim(s) 4, 6, 10 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishida et al. With regard to claim 4, Ishida et al disclose the claimed invention but do not disclose that two o-rings are provided to lock and/or seal the connector assembly. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided two o-rings with a reasonable expectation of success to have a backup in the event of a seal failure, to provide additional sealing security and because duplicating the components of a prior art device is a design consideration within the skill of the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). With regard to claim 6, Ishida et al disclose the claimed invention but do not disclose that a plurality of o-rings are provided to lock and/or seal the connector assembly. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided a plurality of o-rings with a reasonable expectation of success to have a backup in the event of a seal failure, to provide additional sealing security and because duplicating the components of a prior art device is a design consideration within the skill of the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). With regard to claim 10, Ishida et al disclose the claimed invention but do not disclose that o-rings are provided to lock and/or seal the connector assembly. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided two o-rings with a reasonable expectation of success to have a backup in the event of a seal failure, to provide additional sealing security and because duplicating the components of a prior art device is a design consideration within the skill of the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). With regard to claim 12, Ishida et al disclose the claimed invention but do not disclose that a plurality of o-rings are provided to lock and/or seal the connector assembly. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided a plurality of o-rings with a reasonable expectation of success to have a backup in the event of a seal failure, to provide additional sealing security and because duplicating the components of a prior art device is a design consideration within the skill of the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Conclusion The prior art made of record and not relied are examples of connector assemblies with generally a first tube, a bellows tube and at least one o-ring. Applicant's amendment of at least claim 1 necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a).
