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 .
Examiner’s Comments
This office action is examining the amended claims filed on 3/8/24 rather than the claims submitted on 8/15/25 because the claims submitted on 3/8/24 are clearly marked as amended while the claims submitted on 8/15/25 are a duplicate of the originally filed and unamended claims. In response to this action, applicant should present the correct claims from 3/8/24 (or an amended version of those claims).
Election/Restrictions
Applicant’s election without traverse of Group I (claims 1-6) in the reply filed on 10/28/25 is acknowledged.
Claims 7-12 have been withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 10/28/25.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wu et al. (US 2020/0024194).
Claims 1 and 2: Wu et al. (US 2020/0024194) teaches a composition for depositing a corrosion resistant coating which protects from plasma (Abst.; ¶ 0002), the composition comprising: a solid solution including Y2O3 (¶ 0038) and ZrO2, wherein the ZrO2 is present at 10 mol% (¶¶ 0039-0040) and wherein the solid solution has a hexagonal (i.e. claimed hexahedral) crystal structure (¶ 0039).
Claim 3: Wu also teaches the inclusion of other materials, such as hafnium oxide which is present at an amount of 10-20 mol% (¶ 0032).
Claim Rejections - 35 USC § 103
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.
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Wu in light of Wu et al. (US 2018/0240648, hereinafter Wu II).
Claim 4: Wu teaches that other metal oxides can be included (¶ 0032), but fails to teach Nb2O3. Wu II teaches a composition for forming a plasma corrosion resistant film (Abst.) comprising a solid solution of Y2O3 and explains that the solid solution can also include Nb2O3 (¶¶ 0034-0037). The simple substitution of one known element for another to obtain predictable results is prima facie obvious. MPEP § 2143. Thus, it would have been obvious to one of ordinary skill at the time of filing to have selected Nb2O3 as the additional metal oxide in Wu with the predictable expectation of success.
Allowable Subject Matter
Claims 5 and 6 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
None of the prior art on record, taken individually or in combination, fairly teaches or suggests all the limitations of claims 5 or 6. Furthermore, the specification evidences the unexpected results associated with these claimed features.
