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.
Claim 13 is 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 13 recites “a plurality of lateral members provided perpendicular to a longitudinal direction the bridge girder part, the plurality of lateral members connecting the bridge girder parts of the plurality of the air bridges provided at a predetermined interval along a longitudinal direction the bridge girder parts to form a mesh structure” in lines 6-10.
Firstly, the phrase “perpendicular to a longitudinal direction the bridge girder part” should read as perpendicular to a longitudinal direction of the bridge girder parts to be grammatically correct. Secondly, the same phrase “a longitudinal direction the bridge girder parts” has been cited twice, once in lines 6-7 and then in lines 9-10. The second citation in lines 9-10 causes ambiguity as to whether it is referring to the same longitudinal direction of the bridge girder parts cited in lines 6-7 or a different one. For examination purpose, they will be interpreted as same.
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:

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) 6 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chan as applied to claims 1 and 7 above, respectively and further in view of Zhang et al. (US 20220216390 A1; hereinafter “Zhang”).
In re claim 6, Chan discloses in figs. 3-4, the airbridge according to claim 1, but does not expressly disclose wherein at least the bridge girder part includes a mesh structure.
In the same field of endeavor, Chang discloses an airbridge (figs.1-3) wherein at least the bridge girder part (i.e., the top part pf the airbridge 232) includes a mesh structure (¶32).
It 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 to form mesh structure on the bridge girder part of Chan’s airbridge and arrive at the claimed invention. One would have been motivated to do so as Zhang teaches by having openings like a mesh structure on the airbridge, a complete release of the bridge brace material is ensured, and bridge brace material residues are prevented from being left inside the bridge hole, thereby improving the overall device quality of the air bridge and the fabrication accuracy of the air bridge (¶11 of Zhang).
In re claim 12, Chan as modified by Zhang discloses the superconducting circuit apparatus according to claim 7, but does not expressly disclose wherein at least the bridge girder part includes a mesh structure.
In the same field of endeavor, Chang discloses an airbridge (figs.1-3) wherein at least the bridge girder part (i.e., the top part pf the airbridge 232) includes a mesh structure (¶32).
It 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 to form mesh structure on the bridge girder part of Chan’s airbridge and arrive at the claimed invention. One would have been motivated to do so as Zhang teaches by having openings like a mesh structure on the airbridge, a complete release of the bridge brace material is ensured, and bridge brace material residues are prevented from being left inside the bridge hole, thereby improving the overall device quality of the air bridge and the fabrication accuracy of the air bridge (¶11 of Zhang).
Claim(s) 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chan as applied to claim 7 above, and further in view of Adiga et al. (US 20190089033 A1; hereinafter “Adiga”).
In re claim 13, Chan discloses in figs. 1-4, the superconducting circuit apparatus according to claim 7,
wherein the superconducting circuit apparatus includes:
a plurality of the air bridges 112, 113 separately provided in parallel and striding over the third conductor 111 to bridge first and second conductors 104 (¶36-38).
Chan does not expressly disclose a plurality of lateral members provided perpendicular to a longitudinal direction the bridge girder part, the plurality of lateral members connecting the bridge girder parts of the plurality of the air bridges provided at a predetermined interval along a longitudinal direction the bridge girder parts to form a mesh structure.
In the same field of endeavor, Adiga discloses superconducting circuit apparatus (figs. 1-3), wherein a plurality of the air bridges separately provided in parallel (“the pattern is designed such that the bridge will be multiple substantially parallel bridges. For example, the bridge could actually be two bridges with crossbeams connecting the two bridges”; ¶56),
a plurality of lateral members provided perpendicular to a longitudinal direction the bridge girder part, the plurality of lateral members connecting the bridge girder parts of the plurality of the air bridges provided at a predetermined interval along a longitudinal direction the bridge girder parts to form a mesh structure (“the pattern is designed such that the bridge will be multiple substantially parallel bridges. For example, the bridge could actually be two bridges with crossbeams connecting the two bridges. In an embodiment, the etching could form the bridge into a mesh shape with multiple hole” ¶56).
It 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 to form a plurality of bridges with lateral connecting members to form a mesh in the airbridge of Chan and arrive at the claimed invention. One would have been motivated to do so as Chan teaches the holes between multiple airbridges are formed such that the base material can be etched through the one or more holes, and where the set of one or more holes is sized such that metal cannot be deposited through the set of one or more holes (¶56).
