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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 29 December 2022 was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the Office. The information disclosure statement (IDS) submitted on 2 February 2023 was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the Office. Claim Objections Claims 8, 12, and 14 are objected to because of the following informalities: In Claim 8 the language is drawn to “substep (aa) instead of “sub-step (aa)”. In Claim 12 there is an unnecessary “within” to start line 8. In Claim 14, Line 6, “un-der” is used instead of under. 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 2-4 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. As to Claim 2: The claim appears to be drawn to the process when nickel and cobalt are included but does not require nickel and cobalt to be included. Additionally, the steps provided are identical to the steps of the independent claim. Accordingly, it is unclear if nickel and cobalt are intended to be positively recited as present in the instant claim or if the claim is just drawn to repeating the process steps of claim 1. As to Claim 3: The claim appears to be drawn to the process when nickel and cobalt are included but does not require nickel and manganese to be included. Additionally, the steps provided are identical to the steps of the independent claim. Accordingly, it is unclear if nickel and cobalt are intended to be positively recited as present in the instant claim or if the claim is just drawn to repeating the process steps of claim 1. As to Claim 4: The claim appears to be drawn to the process when nickel and cobalt are included but does not require cobalt and manganese to be included. Additionally, the steps provided are identical to the steps of the independent claim. Accordingly, it is unclear if nickel and cobalt are intended to be positively recited as present in the instant claim or if the claim is just drawn to repeating the process steps of claim 1. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 2 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. The claim appears to be drawn to the process when nickel and cobalt are included but does not require nickel and cobalt to be included. Additionally, the steps provided are identical to the steps of the independent claim. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 3 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. The claim appears to be drawn to the process when nickel and manganese are included but does not require nickel and cobalt to be included. Additionally, the steps provided are identical to the steps of the independent claim. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 2 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. The claim appears to be drawn to the process when cobalt and manganese are included but does not require nickel and cobalt to be included. Additionally, the steps provided are identical to the steps of the independent claim. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
