Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
Claims 17-18 and 24-25 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hideki et al. JP 2008000835 (see Examiner provided machine translation).
Regarding claim 17:
Hideki teaches an electric power tool (1) comprising:
a motor including a rotor configured to rotate about a motor rotational axis extending in a front-rear direction (page 4, lines 24-26);
an output part (page 4, lines 26-28: “spindle”) disposed forward of the motor and configured to be rotated in response to rotation of the rotor; and a housing including:
a motor-housing part (2), which houses the motor;
a grip part (3), which extends downward from the motor-housing part; and
a battery-holding part (4), which is connected to a lower-end portion of the grip part; wherein:
in a direction parallel to the front-rear direction, a first distance (see annotated D1 below) between a frontmost end of a lowermost end of the grip part on a front side of the grip part and a frontmost end of the battery-holding part is shorter than or equal to a second distance (see annotated D2) between a rear end part rearmost end of a lowermost end of the grip part on a rear side of the grip part and a rearmost end of the battery-holding part (D1 is shorter than D2).

Regarding claim 18:
Hideki teaches the electric power tool according to claim 17, as discussed above, further comprising: a battery-mounting part (4f1) disposed at a lower portion of the battery-holding part; and a battery pack (9) mounted on the battery-mounting part and being mountable from forward of the battery-holding part (shown in FIG. 8).
Regarding claim 24:
Hideki teaches the electric power tool according to claim 18, as discussed above, further comprising: a hammer disposed forward of the motor and configured to be rotated in response to energization of the motor (page 4, lines 27-28); an anvil disposed forward of the hammer and configured to be impacted by the hammer, the anvil driving the output part (page 4, lines 28-31).
Regarding claim 25:
Hideki teaches the electric power tool according to claim 24, as discussed above, further comprising: a speed reducing mechanism operably coupled between the rotor and the hammer (page 4, lines 26-28).
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 of this title, 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
Claims 19-23 are rejected under 35 U.S.C. 103 as being unpatentable over Hideki, as applied above.
Regarding claims 19-21:
Hideki teaches an impact driver comprising:
a motor having a rotor that rotates around a rotational axis (page 4, lines 24-26);
a hammer disposed forward of the motor and configured to be rotated in response to energization of the motor (page 4, lines 27-28);
an anvil disposed forward of the hammer and configured to be impacted by the hammer (page 4, lines 28-31);
a motor housing (2), which houses the motor;
a grip housing (3) extending downward from the motor housing;
a battery-holding housing (4) disposed downward of the grip housing; and
a battery pack (9), which is mountable on the battery-holding housing by being moved in a front-rear direction relative to the battery-holding housing and has a rated voltage of 18 V or higher (page 5, line 29); wherein:
a frontmost end of the battery pack is disposed more rearward than of the frontmost end of the anvil in the front-rear direction (see annotated D4 below).
Hideki does not explicitly disclose a distance (annotated D3 below) in a direction parallel to the rotational axis from a rearmost end of the motor housing to a frontmost end of the anvil is 120 mm or less; nor a distance (annotated D4 below) in a direction parallel to the rotational axis from the frontmost end of the anvil to the frontmost end of the battery pack is 10 mm or more (or 50 mm/30 mm or less). Hideki does not provide any measurements or dimensions but states “the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention” (page 7, lines 7-8).
Examiner notes that it has been held that where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device, and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device is not patentably distinct from the prior art device (see MPEP 2144.04 IV. A.). Therefore, it would have been obvious to a person having ordinary skill in the art, at the effective filing date of the invention, to modify the dimensions of the tool of Hideki such that D3 is 120 mm or less and D4 is 10 mm or more (or 50 mm/30 mm or less), since changing these dimensions, to the extent such changes are even applicable, would not lead to any change in performance, and represent minor design alterations. A person having ordinary skill in the art might make these changes to move the overall center of gravity of the tool or for general ergonomic purposes.

Regarding claim 22:
Hideki teaches an impact driver (1) comprising:
a motor (page 4, lines 24-26);
a hammer disposed forward of the motor and configured to be rotated in response to energization of the motor (page 4, lines 27-28);
an anvil disposed forward of the hammer and configured to be impacted by the hammer (page 4, lines 28-31);
a motor housing (2), which houses the motor;
a grip housing (3) extending downward from the motor housing;
a battery-holding housing (4) disposed downward of the grip housing; and
a battery pack (9), which is mountable on the battery-holding housing by being moved in a front-rear direction relative to the battery-holding housing and has a rated voltage of 18 V or higher (page 5, line 29).
Hideki does not explicitly teach the shortest distance from a longitudinal center line of the grip housing to the center of gravity of the battery pack is 20 mm or less. Hideki does not provide any measurements or dimensions but states “the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention” (page 7, lines 7-8).
Below is an Examiner annotated FIG. 5 from Hideki, crudely estimating the distance (D6) between a longitudinal center line of the grip housing (CL) to the center of gravity of the battery pack (black square). The figure shows that D6 can be estimated to be relatively small. Examiner notes, however, that it has been held that where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device, and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device is not patentably distinct from the prior art device (see MPEP 2144.04 IV. A.). Therefore, it would have been obvious to a person having ordinary skill in the art, at the effective filing date of the invention, to modify the dimensions of the tool such that D6 is 20 mm or less, since changing this dimension, to the extent such a change is even applicable, would not lead to any change in performance, and represents a minor design alteration. A person having ordinary skill in the art might make this change to move the overall center of gravity of the tool or for general ergonomic purposes.

Regarding claim 23:
Hideki teaches the impact tool according to claim 22, as discussed above, wherein the center of gravity of the battery pack is located forward of the longitudinal center line (see annotated FIG. 5 above).
