Paradis does not disclose wherein each of the sides comprise at least one groove. Butz teaches an apparatus (Fig. 17) comprising a shank (3 in Fig. 17) having at least three sides (top, bottom, left and right sides in annotated Fig. 17), each of the sides comprise at least one groove (grooves in annotated Fig. 17, para. 0050) The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of interdental cleaning devices. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the left, right, and bottom sides of Paradis by adding at least one groove as taught by Butz in order to allow for the device to be rotated between the user’s fingers to make it easier to reach difficult areas between the teeth (Butz para. 0011). In regard to claim 2, Paradis in vies of Butz discloses the invention of claim 1. Paradis further discloses wherein: the at least three sides include left (left side in annotated Fig. 1), right (right side in annotated Fig. 1), and top sides (top side in annotated Fig. 1), the top side extending laterally from the left side to the right side (Fig. 1), and the left, right, and top sides being located at least in a proximal portion of the shank (Figs. 1 and 5A). In regard to claim 3, Paradis in vies of Butz discloses the invention of claim 2. Paradis further discloses wherein: the at least three sides further includes a bottom side (bottom side in annotated Fig. 1), the bottom side extending laterally from the left side to the right side (Fig. 1), and the bottom side being located at least in the proximal portion of the shank (Figs. 1 and 5A). In regard to claim 4, Paradis in view of Butz discloses the invention of claim 2. Paradis does not disclose wherein the top side has a side profile that is convex at least in a distal portion of the shank. Butz teaches an apparatus (Fig. 17) wherein the top side (top side in annotated Fig. 17) has a side profile that is convex (convex section in annotated Fig. 17) at least in a distal portion of the shank (Fig. 17, para. 0050, hyperboloid shape, cross section tapers towards center). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of interdental cleaning devices. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the top side of Rabinowitz in view of Butz to have a side profile that is convex at least in a distal portion of the shank as taught by Butz in order to allow for the device to be rotated between the user’s fingers to make it easier to reach difficult areas between the teeth (Butz para. 0011). In regard to claim 5, Paradis in view of Butz discloses the invention of claim 2. Paradis does not disclose wherein the top side has a side profile that is concave at least in a proximal portion of the shank. Butz further teaches wherein the top side (top side in annotated Fig. 17) has a side profile that is concave (concave section in annotated Fig. 17) at least in a proximal portion of the shank (Fig. 17, para. 0050, hyperboloid shape, cross section tapers towards center). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of interdental cleaning devices. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the top side of Rabinowitz in view of Butz to have a side profile that is concave at least in a proximal portion of the shank as taught by Butz in order to allow for the device to be rotated between the user’s fingers to make it easier to reach difficult areas between the teeth (Butz para. 0011). In regard to claim 10, Paradis in view of Butz discloses the invention of claim 1. Paradis further discloses wherein the pointed oral stimulation tip (20 in Fig. 5A, col. 3 lines 31-33) is a singular pointed oral stimulation tip (21 in Fig. 1) formed of a unitary body (Figs. 1-3, 5A, 7). In regard to claim 11, Paradis in vies of Butz discloses the invention of claim 1. Paradis further discloses wherein the head comprises at least two ridges (ridge 1 and ridge 2 in annotated Fig. 7) extending between the head proximal end and the head distal end (Fig. 7, col. 3 line 5).

The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of handheld dental cleaning devices. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have specified the groove widths of Paradis in view of Butz and Buisson decreases towards the shank proximal end as taught by Buisson in order to allow for improving the grip of the handle on the fingers of the hand (Buisson para. 0009). Response to Arguments Applicant's arguments filed 07 April 2026 have been fully considered but they are not persuasive. In regard to the rejections of the claims under 35 U.S.C. § 103, Applicant argues that Paradis does not disclose the limitations of a neck extending from the shank proximal end to the head distal end of amended independent claims 1, 17 ,and 19. Applicant argues that in Paradis, the head 20 includes a head proximal end 21 at one end and a head distal end 24 at the opposite end, and in Figs. 2 and 3, the neck 13 defines an aperture 15 through which the head 20 passes, and the neck connects to the head 20 by engaging a detent 23 located between the tip 21 and the hub 24. Applicant argues that therefore, in Paradis, the neck connects to a middle portion of the head at the detent, and the head distal end 24 protrudes freely from the opposite side of the aperture and is emphatically not connected to the neck. Applicant argues that because the neck in Paradis does not connect to the head distal end, Paradis fails to teach the claimed structural arrangement, and it would not be obvious to modify Paradis in view of any other reference to have the claimed neck connection because to do so would destroy the intended function and advantages that Paradis teaches with regard to the protrusion of hub 24 beyond the aperture. Examiner notes that in the above rejection, Figures 5A and 7 of Paradis have been re-annotated in order to show the locations of the head distal end and head proximal end in view of the amendments. Examiner notes that Applicant’s arguments are narrower than the claim limitations, as connecting via a detent in the middle of head 20 does not exclude the neck from extending from the shank proximal end to the head distal end. Examiner notes that Applicant argues that the neck in Paradis does not connect to the head distal end, however the neck of Paradis extends from the shank proximal end to the head distal end as annotated Figs. 5A and 7. Examiner notes that Paradis discloses a neck (neck in Figs. 1 and 5A) extending from the shank proximal end (shank proximal end in annotated Figs. 1 and 5A) to the head distal end (head distal end in annotated Figs. 5A and 7), as claimed. Applicant is directed to the rejections in view of the amendments. Applicant argues that secondary reference, Butz, does not cure this fundamental structural deficiency, and the combination of Paradis and Butz fails to teach or suggest the limitations of amended independent claim 1, 17, and 19. Applicant argues that the additional references applied by the Examiner to the dependent claims and remaining independent claims, Rabinowitz (and RD Rubber), Tsurukawa, Ohnishi, and Buisson, do not address, teach, suggest, or otherwise cure the primary deficiencies of Paradis and Butz regarding the claimed neck-to-head connection. Applicant argues that because the cited combinations fail to teach all of the limitations of the independent claims, both the independent claims and the claims depending therefrom are non-obvious, and accordingly, requests the withdrawal of the rejections under 35 U S.C. § 103 for independent claims 1, 17, and 19, as well as all of their respective dependent claims (claims 2-16, 21, and 22). Examiner notes that, as noted above, Paradis discloses the amended limitation of amended independent claims 1, 17, and 19, as claimed. Applicant is directed to the rejections in view of the amendments. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
