Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claims 1, 3-4, 7-8, 10-16 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Legrain et al. (FR 2707851 A1) in view of Zhu (CN 108433318 A) and Masayuki et al. (JPH05184420A).
With regard to claims 1, 4, Legrain et al. discloses a hair styling appliance (Fig. 1) comprising: an airflow unit 4, 5 for generating an airflow; a heating unit 3 for heating the airflow; and a control unit 10 for controlling the airflow unit 4, 5 and the heating unit 3, wherein: the control unit 10 controls the airflow unit 4, 5 and the heating unit 3 in a predefined sequence of modes comprising a first mode (Figs. 3-6, PHASE 1), a second mode (Figs. 3-6, PHASE 2) and a third mode (Figs. 3-6, PHASE 3), the airflow unit 4, 5 having a different flow rate and/or the heating unit having a different heat setting in each of the modes (Figs. 4-6), and the control unit 10 determines when to transition between modes of the predefined sequence (Figs. 1-6, translation, page 4, 3rd paragraph to page 5, line 8), the control unit 10 determines when to transition based on at least one of a time spent in a mode, a presence of hair, and a characteristic of hair (Figs. 3-6). However, Legrain et al. does not disclose wherein the control unit determines when to transition in response to a change in the presence of hair; wherein the characteristic comprises a temperature and/or a moisture content of the hair, and the appliance comprises one or more sensors for sensing the characteristic of the hair. Zhu discloses a hair styling appliance comprising a control unit 2, wherein the control unit 2 determines when to transition in response to a change in the presence of hair (Zhu, translation, page 6, paragraphs 3-8); wherein the characteristic comprises a moisture content of the hair, and the appliance comprises one or more sensors for sensing the characteristic of the hair (Zhu, translation, page 7, 2nd paragraph from bottom). Masayuki et al. discloses a hair dryer, the power of the heater 4 and the air volume/air temperature be controlled according to the water content (i.e. moisture content) of the hair, the moisture content of hair can be estimated from hair temperature (translation, page 4, paragraph three from bottom). Therefore, it would have been obvious to someone with ordinary skill in the art before the effective filing date of the invention to modify the hair styling appliance of Legrain et al. to include one or more sensors for sensing the characteristic of the hair, wherein the characteristic comprises a temperature and/or a moisture content of the hair and further modify the control unit of the hair styling appliance of Legrain et al. to include a function of determining when to transition in response to a change in the presence of hair or the characteristic of hair, wherein the characteristic comprises a temperature and moisture content of the hair as taught by Zhu and Masayuki et al. in order to automatically select and adjust air blowing mode according to the condition of the hair without requiring the user to a prior knowledge of blowing so as to greatly improve the user experience (Zhu, translation, page 2, lines 10-13).
With regard to claim 3, Legrain et al. discloses wherein the control unit 10 determines when to transition in the event that the time spent in a mode and/or a value relating to the characteristic of hair reaches a threshold (Fig. 3).
With regard to claim 7, Zhu discloses the controller 2 can decrease or increase speed to adjust the blowing mode previously selected or determined when detecting the electrical blowing hair being close to or being away from the hair under the condition. If detecting the distance from the electric hair dryer to hair is greater than a predetermined threshold (e.g.,50 cm), it indicates blowing mechanism 3 stops blowing (translation, page 7, lines 10-14). Based on above disclosure, Zhu discloses the hair appliance determining a presence of hair based on changes in the airflow or changes in the speed of the air flow unit. Therefore, it would have been obvious to someone with ordinary skill in the art before the effective filing date of the invention to modify the hair styling appliance of Legrain et al. to include determining a presence of hair based on changes in the airflow or changes in the speed of the air flow unit as taught Zhu in order to automatically select and adjust air blowing mode according to the condition of the hair without requiring the user to a prior knowledge of blowing so as to greatly improve the user experience (Zhu, translation, page 2, lines 10-13).
With regard to claim 8, Legrain et al. discloses wherein the control unit 10 automatically transitions between modes in response to determining when to transition (Figs. 3-6, translation, page 4, 3rd paragraph to page 5, line 8).
With regard to claim 10, Legrain et al. discloses wherein the heat setting in the third mode is lower than the heat settings in the first and second modes (see temperature settings in Figs. 4-6).
With regard to claim 11, Legrain et al. discloses wherein the flow rate in the third mode is lower than the flow rates in the first and second modes (see flow rate settings in Figs. 4-6).
With regard to claim 12, Legrain et al. discloses wherein the flow rate and/or the heat setting in the second mode is lower than that in the first mode (Figs. 4-5).
With regard to claim 13, Legrain et al. discloses wherein the sequence of modes comprises a fourth mode, and the heat setting in the fourth mode is lower than that in the third mode (translation, page 5, lines 6-8 disclose a button 8 for switching on and off the hair dryer, the switch off state of the appliance is considered a fourth mode).
With regard to claim 14, Legrain et al. discloses wherein the sequence of modes comprises a mode in which the airflow unit and/or the heating unit are powered off (translation, page 5, lines 6-8 disclose a button 8 for switching on and off the hair dryer, the switch off state of the appliance is considered a mode in which the airflow unit and the heating unit are powered off).
With regard to claim 15, Legrain et al. discloses wherein the control unit 10 receives user data, and the control unit uses the user data to determine when to transition (Figs. 3-6, translation, page 5, lines 24-29, claims 5-6).
With regard to claim 16, Legrain et al. discloses wherein the user data comprises any of: hair thickness, hair length, natural hair style, hair condition, presence of hair product, and presence of hair dye (Fig. 3, claim 5).
With regard to claim 18, Legrain et al. discloses wherein the control unit 10 initiates the sequence of modes in response to a user input (Fig. 2, translation, page 4, lines 3-28).
Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Legrain et al. (FR 2707851 A1) in view of Zhu (CN 108433318 A) and Masayuki et al. (JPH05184420A) as applied to claim 1 as above, and further in view of Alfredo et al. (GB 2517321 A).
The hair styling appliance of Legrain et al. as modified by Zhu and Masayuki et al. as above includes all that is recited in claim 6 except for wherein the appliance comprises a capacitive sensor for sensing the presence of hair. Alfredo et al. discloses a hair styling appliance 10 comprising a capacitive sensor 564 for sensing the presence of hair (page 31, lines 18-19). Therefore, it would have been obvious to someone with ordinary skill in the art before the effective filing date of the invention to further modify the hair styling appliance of Legrain et al. to include a capacitive sensor for sensing the presence of hair as taught by Alfredo et al. in order to detect the presence of hair without direct contact and provide reliable and efficient measurement solution.
Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Legrain et al. (FR 2707851 A1) in view of Zhu (CN 108433318 A) and Masayuki et al. (JPH05184420A) as applied to claim 1 as above, and further in view of Matsuo et al. (CN 107949293 A).
The hair styling appliance of Legrain et al. as modified by Zhu and Masayuki et al. as above includes all that is recited in claim 9 except for wherein the control unit generates a user alert in response to determining when to transition, and the control unit transitions between modes in response to a user input. Matsuo et al. discloses a hair styling appliance 1 comprising a control unit 12 generates a user alert (Figs. 2, 7, by LEDS 31-35) by in response to determining when to transition (paragraphs [0100]-[0102] and corresponding translation), and the control unit 12 transitions between modes in response to a user input (Fig. 2, user input via mode switch 9). Therefore, it would have been obvious to someone with ordinary skill in the art before the effective filing date of the invention to modify the control unit of the hair styling appliance of Legrain et al. to include functions of generating a user alert in response to determining when to transition, and the control unit transitions between modes in response to a user input as taught by Matsuo et al. in order to optimize the operation of hair styling appliance.
