DETAILED ACTION
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 1-10 are rejected under 35 U.S.C. 103 as being unpatentable over Tsai et al. (US 2016/0033744) in view of Chen et al. (US 2015/0346461).
Regarding claim 1, Tsai (Embodiment 1; figure 1A; Table 1) discloses a lens module comprising a first lens 110 comprising a refractive power, a second lens 120 comprising a convex object-side surface 121, a third lens 130 comprising a refractive power, a fourth lens 140 comprising negative refractive power, a fifth lens 150 comprising a refractive power, and a sixth lens 160 comprising a refractive power, wherein the first to sixth lenses are sequentially disposed from an object side to an image side. Tsai discloses all the claimed limitations except that wherein a thickness along the optical axis of the third lens is greater than a thickness along the optical axis of the first lens, and wherein the lens module has an overall focal length of 1.8 mm to 2.4 mm. However, such features are merely design choice purpose and is well within the knowledge of one skilled in the art. Within the same field of endeavor, Chen (figures 2 and 4) discloses a lens module comprises 6 lenses wherein a thickness along the optical axis of the third lens (0.57) is greater than a thickness along the optical axis of the first lens (0.30), and wherein the lens module has an overall focal length of 1.8 mm to 2.4 mm (2.2mm). Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to implement the above features for design purpose.
Regarding claim 2, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the first lens has a concave image-side surface 112.
Regarding claim 3, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the second lens has a concave image-side surface 122.
Regarding claim 4, Chen (figures 2 and 4) further discloses wherein the third lens has a convex object-side surface 1311.
Regarding claim 5, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the third lens has a convex image-side surface 132.
Regarding claim 6, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the fourth lens has a concave image-side surface 142.
Regarding claim 7, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the fifth lens has a concave object-side surface 151.
Regarding claim 8, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the fifth lens has a convex image-side surface 152.
Regarding claim 9, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the sixth lens has a convex object-side surface 161.
Regarding claim 10, Tsai (Embodiment 1; figure 1A; Table 1) further discloses wherein the sixth lens has a concave image-side surface 162.
