Office Action

§112
DETAILED ACTION 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 . Status of Claims Claims 1-3,5-6 and 11-13 are amended. Claims 7-10 are withdrawn. Claim 14 is new. Claims 1-3, 5-6 and 11-14 are pending. Status of Previous Rejections The rejections of claims 1-6 and 11-13 under 35 U.S.C. 103 as being unpatentable over JP'510 (JP2019-11510, IDS dated 08/22/2023) have been withdrawn in view of the amendment. 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 1-3, 5-6 and 11-14 are 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. Instant Specification discloses that the cold forged gear steel has the recited hardenability. Instant Specification does not disclose that the steel made by other method has the recited hardenability. Therefore, the amended claim 1 has new matter issue. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-3, 5-6 and 11-14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites that J1.5 has a HRC of 38-43, J3 has a HRC of 35-39, J5 has a HRC of 30-34, J7 has a HRC of 26-30 and J9 has a HRC of 21-25. Claim 1 also recites the hardenability each has a range of 4 HRC or less. The relationship between the recited J1.5, J3, J5, J7 and J9 and “a range of 4 HRC or less” is unclear. Please clarify whether the recited value of 4 HRC or less is the difference between the maximum hardness value and the minimum hardness value at each location. Appropriate correction is required. Claim 1 recites GB/T 225-2006. Please clarify the meaning of GB/T 225-2006 because GB/T 225-2006 is not an international standard. Appropriate correction is required. Claim 6 and claim 13 recite GB/T 228-2010. Please clarify the meaning of GB/T 228-2010 because GB/T 228-2010 is not an international standard. Appropriate correction is required. 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). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
