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 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 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Unterberg (EP 2604651 A1, hereinafter referring to the attached ESPACENET translation). Regarding claims 1-20, Unterberg teaches a novel rubber formulation ([0001]), comprising a rubber ([0024]) and an antioxidant such as N,N’-bis-1,4,-(1,4-dimethylpentyl)-p-phenylenediamine (77PD) ([0063]). 77PD reads on the claimed “amine-based antioxidant” because it has an identical structure to the claimed “general formula (1)” wherein “R1” – “R2” are both 1,4-dimethylpentyl groups. These 1,4-dimethylpentyl groups are saturated hydrocarbon groups having 7 carbons, and they therefore also read on the substituents stipulated upon within claims 4, 8, 11, and 17. Unterberg teaches that said antioxidant is included in amounts ranging from 0.1 to 5 phr ([0063]), which falls within and therefore anticipates the claimed range of “0.1 to 11 parts by mass.” Unterberg further teaches the incorporation of anti-aging agents such as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ) ([0062]), in amounts ranging from 0.1 to 5 phr, which encompasses and therefore anticipates the claimed range of “1.75 to 2.5 parts by mass.” This anti-aging argent likewise reads on the specifically claimed antioxidant within claims 3 and 7. Unterberg teaches that the rubber within the formulation is preferably a styrene/butadiene rubber or a polyisoprene rubber ([0035]), which reads on list of rubbers within claim 2. Unterberg further teaches the incorporation of waxes in amounts ranging from 1 to 50 phr ([0066]), which overlaps and therefore anticipates the claimed range within claims 5, 9, 12, 14, 18, and 20. Unterberg teaches the formation of a tire from the inventive composition ([0094]), and therefore meets the limitations of claims 6, 10, 13, 15, 16, and 19.
