Claim Objections
Claims 1 and 21 are objected to because of the following informalities: “were the bridge portion extends” should read “where the bridge portion extends.” Appropriate correction is required.
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 5, 13, 17-18 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.
Regarding claim 5, the recitation “a bridge portion” is unclear. It is unclear if this is the same as, or different from the previously recited “a bridge portion.”
Regarding claim 13, the recitation “wherein the second distance is about 50% of the first distance” is unclear. Specifically, the recitation contradicts claim 11, from which is depends, which requires “a second distance measured in parallel to the longitudinal axis between a first transition and an adjacent third transition is between about 10% to 30% of the first distance.” As 50% falls outside of the required 10-30% range, the scope of the claim cannot be ascertained.
Regarding claim 17, the recitation “a bridge” is unclear. It is unclear if this is in reference to the previously recited “bridge portion” or a separate element therefrom. It is noted that the disclosure does not provide for two distinct bridges as presently recited. Claim 18 is rejected for its dependency.

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) 9-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sasaki (JP2003042677A) in view of Wölk (US7147047B2).
Regarding claims 9-10, Sasaki teaches the limitations of claim 1, and Sasaki does not teach wherein each of the plurality of rise portions and the plurality of fall portions of the first elongated strip comprise one or more louvers formed therein, wherein each of the one or more louvers extend perpendicular to the longitudinal axis, wherein each of the plurality of rise portions and the plurality of fall portions of the second elongated strip comprise one or more louvers formed therein, wherein each of the one or more louvers extend perpendicular to the longitudinal axis.
Wölk teaches (see Fig. 3) wherein each of the plurality of rise portions and the plurality of fall portions (fin portions 4b) of the first elongated strip comprise one or more louvers (gills 7) formed therein, wherein each of the one or more louvers extend perpendicular to the longitudinal axis, wherein each of the plurality of rise portions and the plurality of fall portions (fin portions 4b) of the second elongated strip comprise one or more louvers (gills 7) formed therein, wherein each of the one or more louvers extend perpendicular to the longitudinal axis.
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Sasaki to include the gills of Wölk, in order to improve heat transfer (Col. 2, lines 10-20).
Claim(s) 11-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sasaki (JP2003042677A) in view of Kawamura (WO2021002474A1).
Regarding claims 11-13, Sasaki teaches the limitations of claim 1, and Sasaki does not teach the adjacent first transitions within the first elongated strip are disposed at a first distance apart from each other along the longitudinal axis, and wherein the adjacent second transitions are disposed at the first distance apart from each other, wherein a second distance measured in parallel to the longitudinal axis between a first transition and an adjacent third transition is between about 10% to 30% of the first distance, wherein a distance from the first transition to the second transition is about half of the first distance along the longitudinal axis, wherein the second distance is about 50% (as best understood) of the first distance along the longitudinal axis.
Kawamura teaches (see Fig. 1) the adjacent first transitions within the first elongated strip are disposed at a first distance apart from each other along the longitudinal axis, and wherein the adjacent second transitions are disposed at the first distance apart from each other, wherein a second distance measured in parallel to the longitudinal axis between a first transition and an adjacent third transition is between about 10% to 30% of the first distance (see Pf and offset, defined by Pf/4, or 25%), wherein a distance from the first transition to the second transition is about half of the first distance along the longitudinal axis, wherein the second distance is about 50% (as best understood) of the first distance along the longitudinal axis.
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified to include the distances of Kawamura, as it has been held obvious to try when choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success (see MPEP 2143).
Claim(s) 17-18 and 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sasaki (JP2003042677A) in view of Fukuda (WO9930098A1).
Regarding claim 17, Sasaki teaches the limitations of claim 1, and Sasaki does not teach wherein a bridge extends from the first transition of the first elongated strip to the closest neighboring third transition of the second elongated strip, wherein the first and the second elongated strips are arranged such that a bridge extends from every other first transition to a neighboring every other third transition, and the adjacent first and third transitions to the every other first and third transitions do not have a bridge that connects them
Fukuda teaches wherein a bridge extends from the first transition of the first elongated strip to the closest neighboring third transition of the second elongated strip, wherein the first and the second elongated strips are arranged such that a bridge extends from every other first transition to a neighboring every other third transition, and the adjacent first and third transitions to the every other first and third transitions do not have a bridge that connects them (see alternating connecting portions 63, Fig. 7b).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Sasaki to include every other transitions do not have bridges as taught by Fukuda, in order to reduce weight while maintaining strength (Page 5).
Regarding claim 18, Sasaki teaches the limitations of claim 17, and Fukuda further teaches a second bridge portion that extends from the second transition of the first elongated strip to a closest neighboring fourth transition of the second elongated strip, wherein the first and second elongated strips are arranged such that a second bridge extends from every other second transition to a neighboring fourth transitions, and the adjacent second and fourth transitions to the every other second and fourth transitions do not have a bridge that connects them (see alternating connecting portions 63, Fig. 7b).
Regarding claim 23, Sasaki teaches the limitations of claim 21, and Sasaki does not teach the plurality of second transitions within the first elongate strip and the plurality of third transitions within the second elongate strip do not connect with any bridge portions.
Fukuda teaches the plurality of second transitions within the first elongate strip and the plurality of third transitions within the second elongate strip do not connect with any bridge portions (see Fig. 7a/7c).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Sasaki to include the bridge configuration as taught by Fukuda, in order to reduce weight while maintaining strength (Page 5).
