Office Action

§112
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments with respect to claims 1 and 3-10 have been considered but are moot because the new 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. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1 and 3-10 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding claim 1, there is no written description regarding “wherein a gap is formed between the first sidewall and a lower wall of the paper feeding passage, the gap communicates with the paper feeding passage and the cavity, so that the rear ends of the sheets of paper with the staple or the paper clip move laterally from the paper feeding passage, pass through the gap, and extend into the cavity, wherein the lower wall of the paper feeding passage serves as a wall for blocking further movement of the rear ends of the sheets of paper with the staple or the paper clip”, Instead in the specification and drawings submission on 08/14/2023, in paragraph 0036: is described as “the paper feeding passage is provided with a first sidewall 101 and a second sidewall 102 that are disposed opposite to each other; and figs.3-4 showing that the paper feeding passage does not have a lower wall; figs.3-4 showing that the paper compartments 130 having a lower wall; paragraph 0053 and figs.3-4 showing that the paper compartments 130 and the paper feeding passage are two different separated elements". Therefore, the applicant does not have written support to show that the applicant had possession of the claimed invention at the time of filing based on the applicant’s original disclosure. Therein, the amended claims 1 has introduce a new matter. Claims 3-10 are rejected because they depend from claim 1. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
