DETAILED ACTION
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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 and 10-12 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.
In claim 1, the phrase “near an outermost surface” renders the claim indefinite because the term “near” is a relative term which renders the claim indefinite. The term “near” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Here, the instant specification fails to define what distance range would constitute “near” the outermost surface, and thus the scope of the claim cannot be ascertainable.
Other claims are deemed indefinite in view of their dependence on claim 1.
Response to Arguments
The amendment which recites the content of oxygen in the alloy powder being at least 0.031 and the oxygen film comprises mainly Ni has overcome the rejection. None of the prior art references of record, singly or combined, teaches a Ni-based alloy powder for additive manufacturing comprising more than 0.03 wt% of oxygen and an oxide film wherein the oxide film containing mostly nickel is next or nearest to the outermost surface. Daigo limits the oxygen to 0.03 wt% or less and the metal in the oxide film on the surface is mainly chromium. Other references that teach a Ni-based alloy powder comprising oxygen content of larger than 0.03 wt% does not teach an oxide film in the powder.
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.
