Office Action

§102
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 . 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. Claim(s) 1, 4, 9, 12, 17, 19 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zirun Li, Wenbo Mi, and Haili Bai, Orbital Redistribution Enhanced Perpendicular Magnetic Anisotropy of CoFe3N Nitrides by Adsorbing Organic Molecules ACS Applied Materials & Interfaces 2018 10 (19), 16674-16680 Re claim 1, Li teaches an apparatus for generating a perpendicular magnetic anisotropy comprising a substance (C6H6, C6F6, Sc4H4 molecules) chemisorbed on a surface of a ferromagnet (CoFe3N) forming chemisorbed bonds between the substance and the ferromagnet surface, wherein the chemisorbed bonds formed between the substance and the ferromagnet surface induce perpendicular magnetic anisotropy at an interface between the chemisorbed substance and the ferromagnet (abstract). Re claim 4, Li teaches wherein the ferromagnet comprises at least one material from the group comprising transition metals, alkali metals, and lanthanides, including but not limited to Manganese, Iron, Cobalt, Nickel, Molybdenum, Ruthenium, Rhodium, Palladium, Cesium, Hafnium, Tantalum, Tungsten, Rhenium, Iridium, Platinum, Gadolinium, Terbium, Dysprosium, Holmium, and their alloys, or selected from a group comprising non-metallic materials, including but not limited to ferrites, garnets, rare-earth oxides, Heusler alloys, CrO2, graphene, CrI3, and Cr2Ge2Te-6 (CoFe3N). Re claim 9, Li teaches a method for generating a perpendicular magnetic anisotropy comprising: chemisorbing a substance (C6H6, C6F6, Sc4H4 molecules) on a surface of a ferromagnet (CoFe3N) forming chemisorbed bonds between the substance and the ferromagnet surface, wherein the chemisorbed bonds formed between the substance and the ferromagnet surface induce perpendicular magnetic anisotropy at an interface between the chemisorbed substance and the ferromagnet (abstract). Re claim 12, Li teaches wherein the ferromagnet comprises at least one material from the group comprising transition metals, alkali metals, and lanthanides, including but not limited to Manganese, Iron, Cobalt, Nickel, Molybdenum, Ruthenium, Rhodium, Palladium, Cesium, Hafnium, Tantalum, Tungsten, Rhenium, Iridium, Platinum, Gadolinium, Terbium, Dysprosium, Holmium, and their alloys, or selected from a group comprising non-metallic materials, including but not limited to ferrites, garnets, rare-earth oxides, Heusler alloys, CrO2, graphene, CrI3, and Cr2Ge2Te6 (CoFe3N). Re claim 17, Li teaches an apparatus comprising: a ferromagnet; a reservoir of a substance adjacent the ferromagnet; and a circuit for driving the substance from the reservoir onto a surface of the ferromagnet, wherein the substance is chemisorbed on the surface of the ferromagnet forming chemisorbed bonds between the substance and the ferromagnet surface, and wherein the chemisorbed bonds formed between the substance and the ferromagnet surface induce perpendicular magnetic anisotropy at an interface between the chemisorbed substance and the ferromagnet. Re claim 19, Li teaches wherein the ferromagnet comprises at least one material from the group comprising transition metals, alkali metals, and lanthanides, including but not limited to Manganese, Iron, Cobalt, Nickel, Molybdenum, Ruthenium, Rhodium, Palladium, Cesium, Hafnium, Tantalum, Tungsten, Rhenium, Iridium, Platinum, Gadolinium, Terbium, Dysprosium, Holmium, and their alloys, or selected from a group comprising non- metallic materials, including but not limited to ferrites, garnets, rare-earth oxides, Heusler alloys, CrO2, graphene, CrI3, and Cr2Ge2Te6 (CoFe3N). 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.
