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.
Claims 1-5, 7-10, and 12-20 are rejected under 35 U.S.C. 103 as being unpatentable over James Schatz (US 20160375594 A1 – hereinafter Schatz) in view of Rang-pan Wu (CN111645116 – hereinafter Wu) as evidenced by (US 7013566 B1 – hereinafter Bellm).
Regarding claim 1, Schatz teaches a nose hair cutter (Fig. 1, Shaving Apparatus 100) for
cutting nose hairs, comprising a main part (Fig. 1, Shaving Apparatus 100) formed along an axis
(Fig. 1, vertical axis through the center of the handle) thereof, the main part comprising a cutting
head (Fig. 1, Housing 102) and a handle (Fig. 1, Handle 108) connected thereto on a first end of
the main part (Fig. 1, upper half of Shaving Apparatus 100), wherein a blade (Fig. 5, Blade 104)
is arranged on the cutting head comprising a cutting edge (Fig. 5, Cutting Edge 109) extending in
an axial direction to the axis of the main part, for cutting the nose hairs, wherein the blade is
arranged on the cutting head such that the cutting edge of the blade protrudes at least in portions
from a surface of the cutting head extending in a peripheral direction to the axis of the main part
(Fig. 5, Cutting Edge 109 protrudes from Housing 102), such that the cutting edge intersects the
nose hairs supplied to the cutting edge on an exterior of the cutting head (Fig. 4, Cutting Edge
109 intersects nose hairs), wherein the cutting edge extends in a first plane (Fig. 5, a plane
parallel to Tangent Line 160 and passing through the axis) of the main part extending in a radial
direction to the axis of the main part, and wherein a flat (Fig. 5, inside face of Blade 104 that
protrudes from Cutting Edge 109) facing the axis of the main part is position at least in portions
at an acute angle of attack (Fig. 5, angle of Blade 104; [0042]) relative to the first plane of the
main part, wherein at least one first trough-shaped guide groove (Fig. 6a, closest entrance of Thru-slot 106) for the nose hairs is formed on the surface of the cutting head (Fig. 6a, Housing 102) at least in portions in the peripheral direction with respect to the axis of the main part, into which guide groove the blade (Fig. 6a, Blade 104) projects at least in portions with an edge (Fig. 6a, top horizontal edge connecting to Cutting Edge 109) that forms the cutting edge.
Schatz does not explicitly teach wherein the cutting edge of the blade is inclined relative
to the axis of the main part at an acute angle of inclination.
However, Wu teaches a cutter (Fig. 1), wherein the cutting edge of the blade (Fig. 4, Side
Knife 32) is inclined relative to the axis (Fig. 2, vertical dotted line) of the main part (Fig. 2,
Cover Head 11) at an acute angle of inclination (Fig. 2, Included Angle D; Page 4, para 8. The
angle is between the cover wall and the axis, however since knife 32 is pressed flush against the
cover wall (Page 7, para 4), the angle of inclination is also defined between the axis and the
cutting edge of the knife) in a direction of the first main part end (Fig. 2, top end of Cover Head
11) of the main part.
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the blade of Schatz such that the cutting edge of the blade is
inclined relative to the axis at an acute angle of inclination as taught by Wu. According to Bellm,
it is beneficial to have an acute angle of inclination to yield efficient cutting while minimizing
wear (Bellm; Col 3, lines 54-58).
Regarding claim 2, Schatz further teaches the nose hair cutter according to claim 1,
wherein the angle of attack has a value between 25 degrees and 75 degrees (Fig. 5, angle of
Blade 104; [0042] – an angle of 30 degrees is disclosed).
Regarding claim 3, the combination of Schatz, Wu, and Bellm already teaches h the
nose hair cutter according to claim 1, wherein the cutting edge of the blade is inclined relative to
the axis of the main part at an acute angle of inclination in a direction of the first main part end
of the main part (See the rejection of claim 1 above).
Regarding claim 4, the existing combination of Schatz, Wu, and Bellm does not
explicitly teach the nose hair cutting according to claim 1, wherein the angle of inclination has a
value between 5 degrees and 20 degrees.
However, Wu further teaches wherein the angle of inclination has a value between 5
degrees and 45 degrees (Fig. 2, Included Angle D; Page 4, para 8. The angle is between the cover
wall and the axis, however since knife 32 is pressed flush against the cover wall (Page 7, para 4),
the angle of inclination is also defined between the axis and the cutting edge of the knife).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of inclination of the combination of Schatz, Wu, and
Bellm to have a value between 5 degrees and 45 degrees as taught by Wu. It would have also
been obvious to one of ordinary skill in the art before the effective filing date to modify the angle
of inclination of the combination of Schatz, Wu, and Bellm to have a value between 5 degrees
and 20 degrees as a matter of routine optimization since it has been held that “where the general
conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or
workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233,
235 (CCPA 1955). The angle of inclination is disclosed to be a result effective variable by Bellm
as it needs to be optimized to improve cutting efficiency while minimizing blade wear (Bellm;
Col 3, lines 54-58).
Regarding claim 5, Schatz further teaches the nose hair cutter according to claim 1,
wherein the cutting head (Fig. 1, Housing 102) and the handle (Fig. 1, Handle 108) are connected
to one another for transmission of rotational movement between them (Abstract).
Regarding claim 7, Schatz further teaches the nose hair cutter according to claim 1,
wherein the at least one first trough-shaped guide groove (Fig. 6a, closest entrance of Thru-slot 106) extends longitudinally along the peripheral direction such that the cross section of the at least one first trough-shaped guide groove decreases at least in portions (Fig. 6a, the guide groove is narrower at the top and bottom, and wider in the middle), steadily, with increasing distance from the cutting edge in the peripheral direction to the axis of the main part.
Regarding claim 8, Schatz further teaches the nose hair cutter according to claim 6,
wherein at least one second guide groove (Fig. 6a, furthest entrance of Thru-slot 106) is formed
on the surface, which extends longitudinally in parallel with the first guide groove, at least in
portions, and into which the edge (Fig. 6b, Cutting Edge 109) forming the cutting edge projects
at least in portions transversely to the peripheral direction of the axis of the main part.
Regarding claim 9, Schatz further teaches the nose hair trimmer according to claim 1,
wherein a cavity (Fig. 5, Thru-slot 106) is formed in an interior of the cutting head (Fig. 5,
Housing 102), into which cavity the blade (Fig. 5, Blade 104) projects at least in portions with a
main part of the surface area of the blade, and is held in the cavity in a form-fitting and/or force-
fitting manner, by a holder (Fig. 5, blade is form-fit against the housing; [0038], blade is installed
on the holder, Housing 102).
Regarding claim 10, Schatz further teaches the nose hair cutter according to claim 1,
wherein the cutting head (Fig. 1, Housing 102) is shaped so as to taper conically in the axial
direction relative to the axis of the main part, at least in portions (Fig. 1, top half of Housing 102
tapers in a conical manner in the direction of the axis towards the first end of the main part) , in
the direction of the first end of the main part.
Regarding claim 12, Schatz further teaches the nose hair cutter according to claim 1,
wherein the cutting head (Fig. 5, Housing 102) has at least two blades (Fig. 5, Blade 104) which
are arranged offset to one another in the peripheral direction to the axis of the main part, at an
angle of 180 degrees (Fig. 5, the two blades are 180 degrees offset as they are directly facing
each other).
Regarding claim 13, Schatz further teaches the nose hair cutter according to claim 1,
wherein the angle of attack has a value between 30 degrees and 60 degrees (Fig. 5, angle of
Blade 104; [0042] – an angle of 30 degrees is disclosed).
Regarding claim 14, Schatz further teaches the nose hair cutter according to claim 1,
wherein the angle of attack has a value of approximately 30 degrees (Fig. 5, angle of Blade 104;
[0042] – an angle of 30 degrees is disclosed).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of attack of Schatz to have a value between 44 degrees
and 46 degrees as a matter of routine optimization since it has been held that “where the general
conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or
workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233,
235 (CCPA 1955). The angle of attack is disclosed to be a result effective variable as it needs to
be optimized to provide a desired effectiveness (Schatz, [0042]).
Regarding claim 15, Schatz further teaches the nose hair cutter according to claim 1,
wherein the angle of attack has a value of approximately 30 degrees (Fig. 5, angle of Blade 104;
[0042] – an angle of 30 degrees is disclosed).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of attack of Schatz to have a value of 45 degrees as a
matter of routine optimization since it has been held that “where the general conditions of a
claim are disclosed in the prior art, it is not inventive to discover the optimum or workable
ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA
1955). The angle of attack is disclosed to be a result effective variable as it needs to be optimized
to provide a desired effectiveness (Schatz, [0042]).
Regarding claim 16, the existing combination of Schatz, Wu, and Bellm does not
explicitly teach the nose hair cutting according to claim 1, wherein the angle of inclination has a
value of 10 degrees.
However, Wu further teaches wherein the angle of inclination has a value between 5
degrees and 45 degrees (Fig. 2, Included Angle D; Page 4, para 8. The angle is between the cover
wall and the axis, however since knife 32 is pressed flush against the cover wall (Page 7, para 4),
the angle of inclination is also defined between the axis and the cutting edge of the knife).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of inclination of the combination of Schatz, Wu, and
Bellm to have a value between 5 degrees and 45 degrees as taught by Wu. It would have also
been obvious to one of ordinary skill in the art before the effective filing date to modify the angle
of inclination of the combination of Schatz, Wu, and Bellm to have a value of 10 degrees as a
matter of routine optimization since it has been held that “where the general conditions of a
claim are disclosed in the prior art, it is not inventive to discover the optimum or workable
ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA
1955). The angle of inclination is disclosed to be a result effective variable by Bellm as it needs
to be optimized to improve cutting efficiency while minimizing blade wear (Bellm; Col 3, lines
54-58).
Regarding claim 17, the existing combination of Schatz, Wu, and Bellm does not
explicitly teach the nose hair cutting according to claim 1, wherein the angle of inclination has a
value between 5 degrees and 15 degrees.
However, Wu further teaches wherein the angle of inclination has a value between 5
degrees and 45 degrees (Fig. 2, Included Angle D; Page 4, para 8. The angle is between the cover
wall and the axis, however since knife 32 is pressed flush against the cover wall (Page 7, para 4),
the angle of inclination is also defined between the axis and the cutting edge of the knife).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of inclination of the combination of Schatz, Wu, and
Bellm to have a value between 5 degrees and 45 degrees as taught by Wu. It would have also
been obvious to one of ordinary skill in the art before the effective filing date to modify the angle
of inclination of the combination of Schatz, Wu, and Bellm to have a value of between 5 degrees
and 15 degrees as a matter of routine optimization since it has been held that “where the general
conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or
workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233,
235 (CCPA 1955). The angle of inclination is disclosed to be a result effective variable by Bellm
as it needs to be optimized to improve cutting efficiency while minimizing blade wear (Bellm;
Col 3, lines 54-58).
Regarding claim 18, the existing combination of Schatz, Wu, and Bellm does not
explicitly teach the nose hair cutting according to claim 1, wherein the angle of inclination has a
value between 8 degrees and 12 degrees.
However, Wu further teaches wherein the angle of inclination has a value between 5
degrees and 45 degrees (Fig. 2, Included Angle D; Page 4, para 8. The angle is between the cover
wall and the axis, however since knife 32 is pressed flush against the cover wall (Page 7, para 4),
the angle of inclination is also defined between the axis and the cutting edge of the knife).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the angle of inclination of the combination of Schatz, Wu, and
Bellm to have a value between 5 degrees and 45 degrees as taught by Wu. It would have also
been obvious to one of ordinary skill in the art before the effective filing date to modify the angle
of inclination of the combination of Schatz, Wu, and Bellm to have a value of between 8 degrees
and 12 degrees as a matter of routine optimization since it has been held that “where the general
conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or
workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233,
235 (CCPA 1955). The angle of inclination is disclosed to be a result effective variable by Bellm
as it needs to be optimized to improve cutting efficiency while minimizing blade wear (Bellm;
Col 3, lines 54-58).
Regarding claim 19, Schatz further teaches the nose hair cutter according to claim 1,
wherein the cutting head (Fig. 1, Housing 102) is shaped so as to taper conically, in the manner
of a truncated cone (Fig. 1, top half of Housing 102 tapers in the manner of a shape which
closely resemble a truncated cone in the direction of the axis towards the first end of the main
part), in the axial direction relative to the axis of the main part, at least in portions, in the
direction of the first end of the main part.
Regarding claim 20, Schatz teaches a nose hair cutter (Fig. 1, Shaving Apparatus 100) for cutting nose hairs, comprising a main part (Fig. 1, Shaving Apparatus 100) formed along an axis (Fig. 1, vertical axis through the center of the handle) thereof, the main part comprising a cutting head (Fig. 1, Housing 102) and a handle (Fig. 1, Handle 108) connected thereto on a first end of the main part (Fig. 1, upper half of Shaving Apparatus 100), wherein a blade (Fig. 5, Blade 104) is arranged on the cutting head comprising a cutting edge (Fig. 5, Cutting Edge 109) extending in an axial direction to the axis of the main part, for cutting the nose hairs, wherein the blade is arranged on the cutting head such that the cutting edge of the blade protrudes at least in portions from a surface of the cutting head extending in a peripheral direction to the axis of the main part (Fig. 5, Cutting Edge 109 protrudes from Housing 102), such that the cutting edge intersects the nose hairs supplied to the cutting edge on an exterior of the cutting head (Fig. 4, Cutting Edge 109 intersects nose hairs), wherein the cutting edge extends in a first plane (Fig. 5, a plane parallel to Tangent Line 160 and passing through the axis) of the main part extending in a radial direction to the axis of the main part, and wherein a flat (Fig. 5, inside face of Blade 104 that protrudes from Cutting Edge 109) facing the axis of the main part is position at least in portions at an acute angle of attack (Fig. 5, angle of Blade 104; [0042]) relative to the first plane of the main part. Schatz does not explicitly teach wherein the cutting head comprises two symmetric pieces, however it would have been obvious to one of ordinary skill in the art at the time of filing to modify the form of the cutting head of Schatz such that it comprises two symmetric pieces as a change in form or shape is generally recognized as being within the level of ordinary skill in the art, absent any showing of unexpected results In re Dailey et al., 149 USPQ 47.
Schatz does not explicitly teach wherein the cutting edge of the blade is inclined relative
to the axis of the main part at an acute angle of inclination.
However, Wu teaches a cutter (Fig. 1), wherein the cutting edge of the blade (Fig. 4, Side
Knife 32) is inclined relative to the axis (Fig. 2, vertical dotted line) of the main part (Fig. 2,
Cover Head 11) at an acute angle of inclination (Fig. 2, Included Angle D; Page 4, para 8. The
angle is between the cover wall and the axis, however since knife 32 is pressed flush against the
cover wall (Page 7, para 4), the angle of inclination is also defined between the axis and the
cutting edge of the knife) in a direction of the first main part end (Fig. 2, top end of Cover Head
11) of the main part.
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the blade of Schatz such that the cutting edge of the blade is
inclined relative to the axis at an acute angle of inclination as taught by Wu. According to Bellm,
it is beneficial to have an acute angle of inclination to yield efficient cutting while minimizing
wear (Bellm; Col 3, lines 54-58).
Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over James Schatz
(US 20160375594 A1 – hereinafter Schatz) in view of Rang-pan Wu (CN 111645116 A –
hereinafter Wu) and Mark Bellm et al. (US 7013566 B1 – hereinafter Bellm) as applied to
claim 1 above, and further in view of Aaron Barnes et al. (US 9750639 B2 – hereinafter
Barnes).
Regarding claim 11, the existing combination of Schatz, Wu, and Bellm fails to teach
the nose hair cutter according to claim 1, wherein the main part is formed from two identically
shaped main part components.
However, Barnes teaches a device for insertion into a facial orifice wherein the main part
is formed from two identically shaped main part components (Fig. 6, the two parts of Handle
14).
Therefore, it would have been obvious to one of ordinary skill in the art before the
effective filing date to modify the main part of Schatz, Wu, and Bellm to be formed from two
identically shaped main part components as taught by Barnes as it has been held that a change in form or shape is generally recognized as being within the level of ordinary skill in the art, absent any showing of unexpected results In re Dailey et al., 149 USPQ 47.
Response to Arguments
Applicant's arguments filed 5/7/2026 have been fully considered but they are not persuasive.
Regarding claim 1, Applicant argues that not all features of claim 1 are taught because Schatz does not show the cutting edge 109 of Schatz projecting into the entrance of thru-slot 106. The rejection of claim 1 has been updated such that the horizontal edge of the blade which connects to the cutting edge 109 is shown to be projecting into the entrance of thru-slot 106. This horizontal edge is an edge which forms the cutting edge and it projects at least in portions into the groove, as required by the claim language.
Regarding claim 20, Applicant argues that Barnes does not teach a cutting head that comprises two symmetric pieces. Applicant’s arguments with respect to claim 20 has been considered but are moot because the ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Barnes is not used in the rejection of claim 20.
