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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim 1 – 18 are rejected under 35 U.S.C. 103 as being unpatentable over Egner-Walter et al (WO publication 2009/132982) in view of Shimoyama et al. (U. S. Patent Publication No. 2017/0225661 A1) and Grasso (EP3210841 A1) as cited by Applicant.

The publication to Egner-Walter discloses the invention as is claimed. Egner-Walter (noted cited English language translation) discloses a wiper blade (5, fig. 1) for a vehicle. The wiper blade coupled to the wiper arm comprising a distribution element (21, 30, 31, fig. 4) including an inlet (Annotated Fig. 4), a supply channel (25, 23) for cleaning liquid (para. 5). First and second spray bars (12) are provided for dispensing the liquid through spray openings (14, fig. 5), wherein the cleaning fluid is configured to flow through the inlet (Annotated Fig. 4) and into the supply channel (23; Fig. 4). Note that a spray bar (12, fig. 4) is provided on each end of an adapter (19, 20) that acts to couple the wiper blade with a wiper arm (1). The supply channel comprises a first supply section (generally area within element 31) and a second supply section (generally area 23) for the cleaning liquid to flow in a first and second longitudinal direction. The second supply section is narrowed, or of a reduce lateral width, compared to the first supply section as can be seen in figure 4. The lateral width within the bellows (31) is clearly greater than the lateral width of the flow channel (23).
Egner-Walter does not explicitly teach a first passage configured for cleaning liquid to flow in a first longitudinal direction and a second passage configured for cleaning liquid to flow in a second longitudinal direction opposite to the first direction, and at least one narrowing is provided in the second passage of the second supply section such that the second passage is narrower than the first passage along at least a portion of the first supply section, such that the cleaning liquid must pass through a narrower area moving along the second longitudinal direction than along the first longitudinal direction; wherein the second spray bar is a proximal spray bar having an end that defines an inner circle when the wiper arm is rotated about an axis, and wherein the first spray bar is a distal spray bar having an end that defines a larger outer circle when the wiper arm is rotated about the axis, wherein the narrowing is configured to reduce an amount of cleaning fluid passing through the first spray bar toward the inner circle.
Grass, however, discloses a first passage (16a) configured for cleaning liquid to flow in a first longitudinal direction (Fig. 2) and a second passage (15a) configured for cleaning liquid to flow in a second longitudinal direction opposite to the first direction (Fig. 2), and at least one narrowing is provided in the second passage (See Fig. 2) of the second supply section (15) such that the second passage is narrower than the first passage along at least a portion of the first supply section (16; Fig. 2), such that the cleaning liquid must pass through a narrower area moving along the second longitudinal direction than along the first longitudinal direction (Fig. 2).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the blade of Egner-Walter to further include a first passage configured for cleaning liquid to flow in a first direction and a second passage configured for cleaning liquid to flow in a second direction opposite to the first direction, as taught by Grasso, to provide a wiper apparatus which further stabilizes the injection-target location of washer fluid thus saving on waste in washing fluid.
Shimoyama further discloses a first passage (138a) configured for cleaning liquid to flow in a first direction and a second passage (138b) configured for cleaning liquid to flow in a second direction, and at least one narrowing is provided in the second passage (138b) of the second supply section such that the second passage (138b) is narrower than the first passage (138a) along at least a portion of the supply section (Fig. 18a), wherein the second spray bar (d1) is a proximal spray bar having an end that defines an inner circle (D2, H2; Figs. 9 and 10) when the wiper arm is rotated about an axis (Fig. 21), and wherein the first spray bar (B1, C1) is a distal spray bar having an end that defines a larger outer circle (A2) when the wiper arm is rotated about the axis (Fig. 21), wherein the narrowing (Fig. 18a) is configured to reduce an amount of cleaning fluid passing through the first spray bar toward the inner circle (supply passage 138a is larger than 138b thus allowing for less fluid to pass through the spray bar, further, the nozzle D1 is designed as an eyeball nozzle, further limiting the outlet of the nozzle D1 as compared to B1 and C1; Fig. 17b; Paragraph [0089]).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the blade of Egner-Walter to further include a first passage configured for cleaning liquid to flow in a first direction and a second passage configured for cleaning liquid to flow in a second direction opposite to the first direction, and at least one narrowing is provided in the second passage of the second supply section such that the second passage is narrower than the first passage along at least a portion of the supply section, wherein the second spray bar is a proximal spray bar having an end that defines an inner circle when the wiper arm is rotated about an axis, and wherein the first spray bar is a distal spray bar having an end that defines a larger outer circle when the wiper arm is rotated about the axis, wherein the narrowing is configured to reduce an amount of cleaning fluid passing through the first spray bar toward the inner circle, as taught by Shimoyama, to provide a wiper apparatus which further stabilizes the injection-target location of washer fluid thus saving on waste in washing fluid.
With respect to claim 2, the distribution element (21, 30, 31) is arranged within the adapter (19, 20).
With respect to claim 3, the second supply section comprises nozzles (21.1), same as applicants, for connection to the spray bars. Note that the narrowing is present at such nozzles, at least as compared with the element (31).
With respect to claim 4, the second supply section (generally 23) has a smaller passage than the first supply section (area within bellows 31).
Egner-Walter does not explicitly teach a first region of the first supply section is parallel to and offset from both the first spray bar and the second spray bar, and wherein a second region of the second supply section is parallel to and offset from both the first spray bar and the second spray bar.
Shimoyama discloses a first region of the first supply section (138a; Fig. 18a) is parallel to and offset from both the first spray bar (B1 and C1; Fig. 17b) and the second spray bar (D1; Fig. 17b), and wherein a second region of the second supply section (138b; Fig. 18a) is parallel to and offset from both the first spray bar (B1 and C1; Fig. 17b) and the second spray bar (D1; Fig. 17b).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the blade of Egner-Walter to further include a first region of the first supply section is parallel to and offset from both the first spray bar and the second spray bar, and wherein a second region of the second supply section is parallel to and offset from both the first spray bar and the second spray bar, as taught by Shimoyama, to provide a wiper apparatus which further stabilizes the injection-target location of washer fluid thus saving on waste in washing fluid.
With respect to claims 5 and 8, the first and second spray bars (12) extend along a longitudinal extension of the wiper blade and comprise a plurality of spray openings (14, figs. 4, 5).
With respect to claim 6, the first and second spray bars (12) extend in opposite directions along the extension from the adapter (19, 20, fig. 4) to free ends of the wiper blade.
With respect to claim 7, the wiper of Egner-Walter includes an inner circle side in the same manner as applicant. At least to the extent that such defines any particular structure for the wiper blade. Note that Egner-Walter will have an inner circle side (side extending from the adapter along the wiper arm) in the same manner as applicant.
Egner-Walter does not explicitly teach the narrowing is located in the second region of the second supply section.
Shimoyama discloses the narrowing is located in the second region of the second supply section (138b; Fig. 18a).

Response to Arguments
Applicant’s arguments, see Applicants Arguments/Remarks dated October 17, 2025 with respect to the rejection of claims 1 – 10 under 35 U.S.C. 103 have been fully considered and are not persuasive. Therefore, the rejection has been maintained.
Applicant argues “Grasso is directing fluid to the outer circle and not the smaller inner circle as claimed; however, Grasso was not relied upon to teach this limitation. Shimoyama teaches a narrowing in D1 and further teaches the spraying of said D1 at a location D2 of H2 as shown in Figs. 9 and 10.
