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 9 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Hsieh (5,974,670). Regarding claim 9, Hsieh teaches the invention substantially as claimed except for the space being circular. At the time the invention was made, it would have been an obvious matter of design choice to one skilled in the art to make the space being circular because both the oval space and the circular space provide the same advantage for encircling and cutting a workpiece. Therefore, it would have been an obvious matter of design choice to modify the blades in Hsieh to define a circular space to obtain the invention as specified in claim 9. Regarding claim 20, Hsieh teaches the invention substantially as claimed except for the blades made from stainless steel, plastic, aluminum, or ceramic. To select a well-known material such as stainless steel, plastic, aluminum, or ceramic for the blades would have been obvious to one having ordinary skill in the art, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Response to Arguments Applicant's arguments filed 09/23/2025 have been fully considered but they are not persuasive. Regarding Hsieh reference, the blades in Fig. 3 of the invention and the blades in Hsieh have the same shapes as shown below. Therefore, the blades in Hsieh makes a three-dimensional cut line similar to the invention. PNG media_image2.png 1166 601 media_image2.png Greyscale Regarding Malin reference, each blades in Malin has a curved cutting edge 39 as shown in Fig. 3. Therefore, when the blades complete a cut, the nail has 3-D curve cut line. Conclusion THIS ACTION IS MADE FINAL.
