Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lee (US 20130258506 A1).
Regarding claim 1, Lee discloses (see FIG. 2, ¶s 34-36) an optical element driving mechanism, comprising:
a movable portion (driven object, or lens module, 13) used for connecting an optical element (“driven object 13 can be a lens module”);
a fixed portion (comprising casing 11 and base 12), wherein the movable portion (lens module 13) is movable relative to the fixed portion (casing+base 11+12); and
a driving assembly (electromagnetic driving module 15) used for driving the movable portion (lens module 13) to move relative to the fixed portion (casing+base 11+12).
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 2-3 are rejected under 35 U.S.C. 103 as being unpatentable over Lee, as applied to claim 1 above.
Regarding claim 2, Lee discloses the optical element driving mechanism as claimed in claim 1.
Lee also discloses (see FIGs. 2, 7; ¶s 34-45) the further comprising a guiding assembly (guide mechanism/pin 17) and another assembly (anti-tilt mechanism 14); wherein:
the driving assembly (electromagnetic driving module 15) comprises a plurality of magnetic elements (magnetic members 151) and a plurality of driving coils (coils 152);
the guiding assembly (guide pin 17) comprises at least one guiding element (guide pin 17);
the guiding assembly (guide pin 17) is magnetically permeable (¶ 42: “magnetic-conductive”);
Lee, in the first embodiment (FIGs. 2-7) cited above, does not immediately disclose that the other assembly is a magnetically permeable assembly; wherein:
the magnetically permeable assembly comprises at least one magnetically permeable element;
the magnetically permeable assembly is magnetically permeable.
However, regarding a third embodiment (FIGs. 14-19), Lee discloses that the other assembly (anti-tilt mechanism 14) is a magnetically permeable assembly; wherein:
the magnetically permeable assembly (anti-tilt mechanism 14) comprises at least one magnetically permeable element;
the magnetically permeable assembly (anti-tilt mechanism 14) is magnetically permeable.
(See ¶ 54, describing how friction guide pin 18 replaces rolling member 143 of the anti-tilt mechanism, and how – similarly to guide pin 17 cited above – it includes magnetic(ally permeable/conductive) materials. Note: for simplicity, Lee’s magnetically permeable element shall be mapped to the rolling member 143 for the remainder of this action.)
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the teachings and embodiments of Lee by providing the rolling members with magnetically permeable materials, in order to tailor/improve the guiding, magnetic anti-tilting, and frictional aspects of the driving mechanism (Lee ¶s 42-43, 54).
Regarding claim 3, modified Lee discloses the optical element driving mechanism as claimed in claim 2.
Lee, in the first embodiment cited above, further discloses (see FIGs. 2,7) wherein:
a sum of a number of the guiding elements (i.e. one guide pin 17) and a number of the magnetically permeable elements (i.e. one rolling member 143) is identical to a number of the magnetic elements (i.e. two magnetic members 151);
the sum of the numbers of the guiding elements (i.e. one guide pin 17) and the numbers of the magnetically permeable elements (i.e. one rolling member 143) is equal to a number of the driving coils (i.e. two coils 152).
(Note also that, in ¶ 40, Lee discusses increasing the number of magnets 151 and coils 152; naturally the number of guiding elements may scale commensurately to accommodate such design variants, as Lee explicitly touts the benefits of the arrangement’s symmetry.)
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Lee, as applied to claim 3 above, and further in view of Hu (US 20130064535 A1, hereinafter Hu1).
Regarding claim 4, modified Lee discloses the optical element driving mechanism as claimed in claim 3.

the first magnetically permeable element (rolling member 143) is disposed on the second corner;
the second magnetically permeable element (rolling member 143) is disposed on the fourth corner.
(See annotated FIG. 7+13’s right panel above)
Lee and Hu1 are related as being directed towards electromagnetic driving devices with anti-tilt features.

[AltContent: textbox (FIG. 5A of Hu1 is annotated to highlight the two guiding rods 141 and 141’. First and third corners are numerically labeled)]the at least one guiding element comprises a first guiding element (guiding rod 141) and a second guiding element (guiding rod 141’);
the second guiding element (guiding rod 141’) is disposed on the third corner (i.e. of lens support 121);
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further combine design aspects of Lee’s embodiments, in order to reduce motional tilt (Lee ¶ 50) – or more generally, to provide a more symmetric design and distribution of constraining/driving forces that would accommodate a greater number of magnets/coils (as Lee briefly mentions in ¶ 40).
It would have also been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify Lee with the teachings of Hu1, again to support a symmetric device design and facilitate effective driving and anti-tilt features.
Claims 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Hu1, as applied to claim 4 above, and further in view of Hong (CN 104079138 A).
Regarding claim 5, modified Lee discloses the optical element driving mechanism as claimed in claim 4.
Lee, in the first embodiment cited above, further discloses (see above annotated FIG. 7+13’s left panel) wherein:

a normal vector of the second magnetically permeable element (rolling member 143) is perpendicular to the first direction (perpendicular to the optical axis).
Modified Lee does not disclose that the first magnetically permeable element and the second magnetically permeable element are plate-shaped.

Hong discloses (see FIGs. 5-6, ¶s 53-55) that the first magnetically permeable element (magnetic conductive baffle 112) and the second magnetically permeable element (magnetic conductive baffle 112) are plate-shaped.
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further modify Lee with Hong’s plate-shaped structures, in order to accommodate the geometries of the device’s interior structure and fields, and enhance magnetic field efficiency, structural strength, and stability (Hong ¶s 54-55).
Regarding claim 6, modified Lee discloses the optical element driving mechanism as claimed in claim 5.
Lee, in the first embodiment cited above, further discloses (see above annotated FIG. 7+13’s left panel) wherein: the first guiding element (guide pin 17) and the second guiding element (guide pin 17) are in direct contact with the movable portion (lens module 13).

Modified Lee does not disclose:

the first surface is exposed from the third magnetically permeable element;
the second surface is exposed from the third magnetically permeable element.
Lee and Guo are related as being directed towards electromagnetic driving devices.
Guo discloses (see annotated FIG. 2A below, and pgs. 1-2 of the translated Description):
the optical element driving mechanism further (voice coil motor 3) comprises a third magnetically permeable element (magnetic conductive member 22) disposed on the first magnetic element (magnetic column 20);
the first surface is exposed (first end 210) from the third magnetically permeable element (magnetic conductive member 22);
[AltContent: textbox (FIG. 2A of Guo is annotated to highlight various features)]

the second surface (second side 208) is exposed from the third magnetically permeable element (magnetic conductive member 22).
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further modify Lee with Guo’s magnetic conductive member as a third magnetically permeable element, in order to reduce the generation of ineffective magnetic lines (Guo Description pg. 1) for improved stability and electromagnetic thrust.
Regarding claim 8, modified Lee discloses the optical element driving mechanism as claimed in claim 7.
Guo further discloses (see annotated FIG. 2A above) wherein the first magnetic element (first end 210) and the first magnetically permeable element (magnetic conductive member 22) at least partially overlap each other when viewed in a direction perpendicular to the second surface (second side 208).
Regarding claim 9, modified Lee discloses the optical element driving mechanism as claimed in claim 8.
Guo further discloses (see annotated FIG. 2A above) wherein:
the first magnetic element (magnetic column 20) further comprises a third surface (second end 212), a fourth surface (first side 206), a fifth surface (top 202), and a sixth surface (bottom 204);
the third surface (second end 212) is opposite to the first surface (first end 210);
the fourth surface (first side 206) is opposite to the second surface (second side 208);
the fifth surface (top 202) is adjacent to the first surface (first end 210), the second surface (second side 208), the third surface (second end 212), and the fourth surface (first side 206);
the sixth surface (bottom 204) is adjacent to the first surface (first end 210), the second surface (second side 208), the third surface (second end 212), and the fourth surface (first side 206);
the fifth surface (top 202) is opposite to the sixth surface (bottom 204);
the third magnetically permeable element (magnetic conductive member 22) is disposed on the fourth surface (first side 206);
the third magnetically permeable element (magnetic conductive member 22) is disposed on the fifth surface (top 202);
the third magnetically permeable element (magnetic conductive member 22) is disposed on the sixth surface (bottom 204).
Modified Lee does not disclose that the third magnetically permeable element is disposed on the third surface. However, Examiner finds that this lone discrepancy between the prior art and the claimed invention may only amount to a mere change in shape – i.e. of the third magnetically permeable element disclosed by Guo, so that it covers the third surface.
It would have also been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further modify Lee incorporating Guo’s third magnetically permeable element, in order to further reshape/reduce undesirable magnetic field lines – since it has been held that changes in shape are generally within the level of ordinary skill in the art. In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966).
Regarding claim 10, modified Lee discloses the optical element driving mechanism as claimed in claim 9.
Lee, in the in the first embodiment cited above, further discloses (see annotated FIG. 7 above) wherein at least a portion of the movable portion (driven object, or lens module, 13) has the first magnetic element (magnetic member 151) mounted into it. (See also ¶ 39: “…magnetic member 151 which is exteriorly mounted to the lens module 13”)
Guo further discloses wherein the third magnetically permeable element (magnetic conductive member 22) partially encloses the first magnetic element (magnetic column 20).
Modified Lee does not explicitly disclose wherein at least a portion of the movable portion is disposed between the third magnetically permeable element and the first magnetic element. However, Examiner finds that any possible discrepancy between the claimed invention and the above-cited prior art may only amount to a mere rearrangement of parts, as the combined art essentially suggests there simply being two main design options – i.e. where the mounting portion of the movable portion is disposed around the third magnetically permeable element and the first magnetic element, or between them as claimed.
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further modify Lee incorporating Guo by arranging the portion of the movable portion between the third magnetically permeable element and the first magnetic element to maintain engagement between the magnetic element and movable portion – since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70.

the first bonding element (conductive connecting component 17)and the second bonding element (conductive connecting component 17) comprise different materials.
It would have therefore been obvious for one of ordinary skill in the art, before the effective filing date of the claimed invention, to further combine Lee with the conventional designs disclosed by Hu2, in order to realize magnetic driving configurations that are already known to operate reliably and effectively (Hu2 ¶ 4).
Regarding claim 12, modified Lee discloses the optical element driving mechanism as claimed in claim 11.
