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 .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Claim Rejections - 35 USC § 102
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 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 1-11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WIPO Publication Number 2020/203484 (U.S. Patent Application Publication Number 2022/20185742 utilized as translation and cited as “Yamashita”).
In regards to independent claim 1 and dependent claims 2-3 and 8, Yamashita is directed to a coating layer-bonded continuous ceramic fiber and a ceramic matrix composite material. (¶1) This would correspond to a component. The coating layer-bonded continuous ceramic fiber is formed from a continuous ceramic fiber having a coating layer of a metal compound with a thickness of 50 nm or less on the surface. (¶13)
The ceramic matrix is at least one of alumina and mullite. (¶65) This corresponds to a ceramic matrix as set forth in the instant claim.
Any method may be used as the method for composition, however the preferred method includes impregnating continuous ceramic fibers with a slurry including a raw material of the ceramic matrix and then heat-treating this resultant. (¶63) This corresponds to the claimed method.
As to claim 4, Yamashita teaches that the CMC includes 25% by mass alumina and 75% by mass of mullite. (¶107) This falls within the claimed range.
As to claim 5, the continuous fiber of Yamashita is an alumina fiber or a mullite fiber. (¶16)
As to claim 6-7,Yamashita teaches a plate-shaped CMC includes 33.4% by volume of the fibers and the density being 2.48 g/cm3. (¶109) These fall within the claimed range.
As to claim 9, Yamashita teaches a CMC with particle sizes is 0.19 microns and 1.66 microns. This falls within the claimed ratio.
