Status of Claims
Below is the Final Action on the Merit for claims 7 – 12 and 20 – 25. Claims 1 – 6 and 13 – 19 are cancelled.
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) 7 – 12 and 20 - 25 are rejected under 35 U.S.C. 103 as being unpatentable over Scherrer et al (EP 3381404 A1) in view of Minoletti (US 6230716 B1), and in further view of Skelton (US 2899966 A) and as evidenced by Yoshida (US 20050020325 A1).
In re Claim 7, Scherrer et al discloses a personal care implement (electric toothbrush, Fig. 1a: 1) comprising: a head (rotatable brush head, 61) and a handle (hand part, 10), the handle comprising a core-connector unit (fixing element Fig. 5c: 121 that contains a second sleeve section, 123),wherein the core-connector unit (fixing element Fig. 5c: 121 that contains a second sleeve section, 123) comprises,
coupling pin (Fig. 8d: 12)l the pin is made from stainless steel (Paragraph [0234]) and comprises a cage (bearing pin receptacle (Paragraph [0239]) for releasably engaging into the head (arranged for connecting hand part to brush attachment, see [0040]); the head (rotatable brush head, 61) being repeatedly attachable to and detachable from the handle (multiple heads can be attached and detached, see [0002]), the personal care implement (electric toothbrush, 1) exhibiting a distinctive sound as the pin is captured in the cage (detent notch of the snap element) of the snap element – thus attaching the head gets attached to the handle, thereby providing a signal of secure attachment, (control pin can contain a locking notch, for snapping or snapping a locking element on the brush attachment part merging with handpiece, the engagement of the locking element may also give an acoustic feedback to secure the brush attachment part, see [0045]).
Scherrer et al does not teach, wherein the handle comprises a stainless steel spring-loaded ball-snap element, comprising a cage, a ball and a spring, the spring applying an outwardly radial force onto the ball which is captured in the cage, providing a long-lasting, reliable fixation of the head on the connector as well as a distinctive sound with substantially no reverberation time to a user during engagement the personal care implement exhibiting the distinctive sound as the ball is captured by the cage of the spring0loaded ball snap element; and the sound being characterized by a tonal component of about 4000Hz to about 6000Hz, over a time length of about 0.Is to about 0.3s on a tonality frequency vs. time analysis (Hearing Model of Sottek).
Minoletti, however, teaches a quickly removable head from a brush handle, wherein the handle comprises a spring-loaded ball-snap connector (quick disconnect mechanism, Fig. 1: 50) and spring applying an outwardly radial force onto the ball (spring, 54 applies radial force onto ball, see annotated Fig. 1 below), providing a long-lasting, reliable fixation of the head on the connector (In this manner, rotation of the brush head 12 and inadvertent withdrawal of the brush handle 30 are prevented while allowing the brush handle 30 to be quickly withdrawn at a desired time, see Col. 4: Lines 30 – 40) as well as a distinctive sound with for the most part no reverberation time during engagement (provides a different sound as if feels the void, see Col. 4: Lines 30 – 40; and is provided by Scherrer et al: exhibiting a sound when the head gets attached to the handle, detached from the handle, or both (Paragraph [0045]).

Therefore, it would be obvious to one of ordinary skill in the art before the effective filing date of invention to modify Scherrer et al. with the teachings of handle comprises a spring-loaded ball-snap connector and a spring applying an outwardly radial force on ball as taught by Minoletti because it provides for a quick disconnect of handle from head to help user avoid coordination problems, avoid a fixed handle that may interfere with brushing, quickly and easily removed without significant force, and possibility of utilizing a plurality of brush heads (Minoletti: Col. 3: Lines 9 – 35).
Additionally, Scherrer et al/Minoletti teaches the personal care implement having a spring-loaded ball-snap element comprising a ball and spring but is silent on the material that both are made of stainless steel.
However, Skelton teaches hair curlers, having a ball and spring both made of stainless steel (The ball and spring are advantageously of stainless steel, see Col. 2: Lines 14 – 15). Accordingly, the prior art references teach that it is known that having a ball and spring are advantageously made of stainless steel. Therefore, it would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have this stainless steel material as it would have resulted in the predictable result of a modification that would amount to one known manner of providing corrosion resistance, durability, strength and a long lifespan.
Scherrer et al. teaches the personal care implement (electric toothbrush, 1) exhibiting a sound when the head gets attached to the handle, detached from the handle, or both (Paragraph [0045]), thereby providing a signal of secure attachment or detachment, the sound being characterized by a tonal component (Paragraph [0045] – the locking element is provided with acoustic feedback). Scherrer, in providing the acoustic feedback, teaches the tonal component having a range in Hz over a given time length on a tonality frequency vs. time analysis but fails to explicitly teach the range of about 4000Hz to about 6000Hz, over a time length of about 0.1s to about 0.3s.
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 implement of Scherrer to explicitly teach the range of about 4000Hz to about 6000Hz, over a time length of about 0.1s to about 0.3s, as claimed, since such a modification would have involved a mere change in the number of cycles or oscillations of a component. A change in the number of cycles or oscillations is generally recognized as being within the level of ordinary skill in the art. Further, the use of sound signaling a secure attachment of a head on a handle provides the technical effect of making the user aware that the parts are securely attached to each other. Scherrer teaches this limitation. The claimed pitch and duration of the signal do not provide any further technical benefit in this respect and is evident in Yoshida (U.S. Patent Publication No. 2005/0020325 A1) where the reference also teaches in Paragraph [0125] a feeling of lock at the time of attachment of replacement brush 50 to stem 40 (to inform the user of the completion of attachment by use of sound and sense of a hand) is important to prevent the user from forcibly pushing replacement brush 50 into the stem, and is effective at reducing the damage of stem 40 and replacement brush 50. Therefore, the sound provided at a pitch and time sufficient to prevent damage to the device while alerting a user of the proper connection.
In re Claim 8, Scherrer et al as modified teaches the personal care implement according to claim 7, wherein the sound is characterized by a tonal component over a given Hz range and further over a time length, on a tonality frequency vs. time analysis (Hearing Model of Sottek) (Scherrer et al: use of sound over length of time is taught by Scherrer et al as the reference teaches a sequence of a head securely attaching to a handle proving a tonal component, see [0045]).
Scherrer does not explicitly teach the range of 4800Hz to about 5400Hz, or a time length of about 0.12s to about 0.28s.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify a tonality frequency and time of Scherrer to further explicitly teach the range of 4800Hz to about 5400Hz, or a time length of about 0.12s to about 0.28s, as claimed, since such a modification would have involved a mere change in the range/time of a component. A change in range/time is generally recognized as being within the level of ordinary skill in the art (MPEP 2144.04). This modification would allow a sufficient signal to the user that the handle has been connected properly.
In re Claim 9, Scherrer et al as modified teaches the personal care implement according to claim 7, wherein the sound has a sound level vs. time (Scherrer et al: use of sound over length of time is taught by Scherrer et al as the reference teaches a sequence of a head securely attaching to a handle proving a tonal component, see [0045]).
Scherrer does not explicitly teach the sound has a sound level vs. time of about 50dB(A) to about 60dB(A), over a time period of about 0.12 to about 0.28s
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify sound of Scherrer to further explicitly teach the sound has a sound level vs. time of about 50dB(A) to about 60dB(A), over a time period of about 0.12 to about 0.28s, as claimed, since such a modification would have involved a mere change in the range/time of a component. A change in range/time is generally recognized as being within the level of ordinary skill in the art (MPEP 2144.04). This modification would allow a sufficient signal to the user that the handle has been connected properly.
In re Claim 10, Scherrer et al as modified teaches the personal care implement according to claim 7, wherein the sound has a loudness vs. time (Scherrer et al: use of sound over length of time is taught by Scherrer et al as the reference teaches a sequence of a head securely attaching to a handle proving a tonal component, see [0045]).
Scherrer does not explicitly teach wherein the sound has a loudness vs. time of about Isone GF to about 3sone GF, over a time period of about 0.12 to about 0.28s, as measured according to ISO 532-1
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 sound of Scherrer to further explicitly teach wherein the sound has a loudness vs. time of about Isone GF to about 3sone GF, over a time period of about 0.12 to about 0.28s, as measured according to ISO 532-1, as claimed, since such a modification would have involved a mere change in the range/time of a component. A change in range/time is generally recognized as being within the level of ordinary skill in the art (MPEP 2144.04). This modification would allow a sufficient signal to the user that the handle has been connected properly.
In re Claim 11, Scherrer et al as modified teaches the personal care implement according to claim 7, wherein the sound has a tonality vs. time (Hearing Model of Sottek; Scherrer et al: use of sound over length of time is taught by Scherrer et al as the reference teaches a sequence of a head securely attaching to a handle proving a tonal component, see [0045]).
Scherrer does not explicitly teach wherein the sound has a tonality vs. time (Hearing Model of Sottek) of about 0.1tuHMS to about 1.2tuHMS
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 sound of Scherrer to further explicitly teach the sound has a tonality vs. time (Hearing Model of Sottek) of about 0.1tuHMS to about 1.2tuHMS, as claimed, since such a modification would have involved a mere change in the range/time of a component. A change in range/time is generally recognized as being within the level of ordinary skill in the art (MPEP 2144.04). This modification would allow a sufficient signal to the user that the handle has been connected properly.
In re Claim 12, Scherrer et al as modified teaches the personal care implement according to claim 7, wherein the personal care implement is an electrically operated toothbrush (Scherrer et al: electrical toothbrush, 1).
In re Claim 20, Scherrer et al as modified teaches the personal care implement according to claim 10, wherein the sound has a specific loudness (Scherrer et al: use of sound over length of time is taught by Scherrer et al as the reference teaches a sequence of a head securely attaching to a handle proving a tonal component, see [0045]).
Scherrer does not explicitly teach a specific loudness of about 5sone GF to about 9sone GF, over a time period of about 0.12 to about 0.28s, as measured according to ISO 532-
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 loudness of Scherrer to further explicitly teach a specific loudness of about 5sone GF to about 9sone GF, over a time period of about 0.12 to about 0.28s, as measured according to ISO 532-, as claimed, since such a modification would have involved a mere change in the range/time of a component. A change in range/time is generally recognized as being within the level of ordinary skill in the art (MPEP 2144.04). This modification would allow a sufficient signal to the user that the handle has been connected properly.
In re claim 21. Scherrer et al as modified teaches the personal care implement (10, 100, 2000) according to claim 7, wherein the core-connector unit (Scherrer et al: fixing element Fig. 5c: 121 that contains a second sleeve section, 123) is formed as one piece that cannot be separated without destroying the unit (Scherrer et al: formed as one piece, see Fig. 5c).
In re claim 22. Scherrer et al as modified teaches the personal care implement (10, 100, 2000) according to claim 7, wherein the core- connector unit (Scherrer et al: fixing element Fig. 5c: 121 that contains a second sleeve section, 123) is at least partially embedded in another handle material (Scherrer et al: first receiving sections, 23).
In re claim 23. Scherrer et al as modified teaches the personal care implement (10, 100, 2000) according to claim 7, wherein the handle (Scherrer et al: handle, 91) further comprises a second component at least partially covers the core-connector unit (Scherrer et al: second receiving sections, 24).
In re claim 24. Scherrer et al as modified teaches the personal care implement (10, 100, 2000) according to claim 23, wherein the core- connector unit together with the second component defines an overall length extension of the handle (Scherrer et al: fixing element Fig. 5c: 121 that contains a second sleeve section, 123 and second receiving sections, 24; defines the length extension of handle, 91 to the hand part, 10, see Fig. 8d).
In re claim 25. Scherrer et al as modified teaches the personal care implement (10, 100, 2000) according to claim 23, wherein the core- connector unit is overmolded with the second component (Scherrer et al: fixing element Fig. 5c: 121 that contains a second sleeve section, 123; states that several hard components such as the handle housing or the carrier body can use a multi component injection molding process which can include complete overmolding, see [0411 – 0413]).
Response to Arguments
Applicants Arguments/Remarks dated November 10, 2025 with respect to the rejection of claims 7 – 12 and 20 – 25 under 35 U.S.C. 103 have been fully considered and they are not persuasive. Therefore, the rejection has been maintained.
Applicant argues the material properties of the elements to provide the distinct sound of attachment and how providing a different material would produce a different sound.
Examiner, however, notes Scherrer et al teaches the bearing pin is made of stainless steel as discussed in Paragraph [0234]) and further teaches providing acoustic feedback as discussed in Paragraph [0045]). Examiner is relying on Minoletti to supply with Scherrer et al is lacking, that being a ball instead of a pin.
