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 . Response to Arguments Applicant's arguments filed 7/9/26 have been fully considered but they are not persuasive. The rejections still apply as presented previously. No amendment has been filed. The Applicant posits in the Remarks that the viscoelastic properties the claimed polymer are not determined solely by the monomer composition (styrene/butadiene), but are the result of controlling a complex microstructure such as the composition, microstructure, molecular weight, or end functional group (polymerization initiation end or polymerization termination end) of the polymer. It is the Office’s position that Applicant should then claim the complex microstructure because the composition that is claimed is taught by the reference. Applicant’s assertion that the G’ and tanδ values have effects on battery performance still considered a new property of an old material since the claimed material is taught. Applicant asserts that Table 1 evidences that not all similar materials, e.g., Comparative Examples 1 and 2, have the claimed properties but Table 1 also proves that the known materials have the claimed properties, as well. 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 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sone (US 2013/0260241 A1). Regarding claim 1, Sone discloses a composition comprising: a copolymer comprising 1,3-butadiene (paragraph 60) and styrene (paragraph 62). Something which is old does not become patentable upon the discovery of a new property (MPEP 2112 I). The manner in which the properties are measured does not change the intrinsic properties. Regarding claim 2, the instant specification states that α is the hydrogenation ratio (paragraph 90). Sone discloses a hydrogenation ratio of .65 (paragraph 199). Regarding claim 3, Sone discloses that the styrene content is 0-50% (paragraph 62). Regarding claim 4, Sone discloses a functional group containing a nitrogen atom, an oxygen atom, a silicon atom, a germanium atom, a tin atom or a combination thereof (paragraph 20). Conclusion THIS ACTION IS MADE FINAL. 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.
