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 Xue (Xue and Islam. Improving corrosion and wear resistance of A36 steel by laser cladding of FeCrBSi and FeCrNiCoMoBCuSi alloys. Surface Modification Technologies XII, Proceedings of the International Conference on Surface Modification Technologies, 12th, Rosemont, Ill. Oct. 12-14, 1998. Pp. 449-456.).
Regarding claim 1, Xue discloses an alloy that falls within the scope of that claimed (FeCrNiCoMoBCuSi powder, Table 1),
with a weight ratio of Fe to 100 parts by weight of the first component of 1.3 to 2.0 times the weight ratio of Ni to 100 parts by weight of the first component (Fe of 60 is 1.5 times Ni of 40).

Regarding claim 2, Xue discloses the second component contains Cr (32 wt%), and further contains one or more selected from Co (9 wt%), Mo (4 wt%), and Cu (2.4 wt%) (FeCrNiCoMoBCuSi powder, Table 1).
Regarding claim 3, Xue discloses a weight ratio of Cr to 100 parts by weight of the first component is 0.63 times to 1.39 times the weight ratio of Fe to 100 parts by weight of the first component (Cr of 68 is 0.88 times Fe of 60) (FeCrNiCoMoBCuSi powder, Table 1).
