Office Action

§103 §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 . Response to Arguments Applicant’s arguments 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. Previous 35 USC 112 rejections were 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 1-6 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 order of the steps/paragraph order is confusing. It is unclear if the aluminum compound is meant to be only an aluminum containing gas, or if it is the insulation film. Formula 2 needs to be distinguished in the claim as a compound or a film. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 1-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Khadelwal et al. (US 2019/0040279 A1) in view of Paranjpe (US 2003/0134038 A1). As to claim 1, Khaldelwal teaches forming an insulation film with flowable CVD with the claimed aluminum precursors and hydrogen/oxygen containing gas that creates forming a film that includes (method comprises, will include) a flowable oxygen containing aluminum compound. The aluminum containing gas and hydrogen containing gas are coreactants in para para 0968-1010. The film is further annealed in para 1010. Khaldelwal teaches the elements of the claims as alternatives and not necessarily as one embodiment. Paranjpe teaches an aluminum containing gas of that claimed, a hydrogen containing gas with remote plasma to form an oxygen containing aluminum compound (para 0070, 0005). Annealing occurs to finish the film in para 0080-0081. Therefore, it would have been obvious to one of ordinary skill in the art to use the combination of claimed elements in Khadelwal as taught by Parnajpe as Paranjpe teaches the art recognized suitability and utility of such. As to claim 2, trimethylaluminum is used in Paranjpe para 0070, Khadelwal para 0968-1010. As to claim 3, Khadelwal teaches the aluminum compound as an additive gas or secondary reactant in para 0968-1010. As to claim 4, the hydrogen containing gas is as claimed in Paranjpe para 0070, Khadelwal para 0968-1010. As to claim 5, the claim is unclear as to whether the temperature is the annealing temperature or the film forming temperature. Thus, this is taught in Khandelwal para 1200. Further, Paranjpe repeatedly designates the annealing temperature as a result effective variable in order to gain the required film properties (para 0080). It would have been obvious to a person having ordinary skill in the art at the time the invention was made to include the claimed annealing temperature, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 220 F.2d 454, 105 USPQ 223 (CCPA 1955). As to claim 6, the annealing is in a non-oxidizing atmosphere in Paranjpe para 0080-0081. 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.
