Office Action

§102 §112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Election/Restrictions Applicant’s election of Group I, claims 1-10 in the reply filed on 8/13/2026 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.03(a)). Claims 11-16 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 8/13/2026. Claim Objections Claim 1 objected to because of the following informalities: (wherein x is…), the parentheses should be removed. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (B) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-10 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 1 recites “R contains a sulfur atom and contains a thiocarbamoyl group having an aromatic hydrocarbon or an aliphatic hydrocarbon, a benzothiazole group having an aromatic hydrocarbon or an aliphatic hydrocarbon, or a -SO₃-Na⁻ group”. The limitation is unclear due to the use of “and” and “or”. For purposes of expediting prosecution, the claim is interpreted as R contains 1) a sulfur atom and contains a thiocarbamoyl group having an aromatic hydrocarbon or an aliphatic hydrocarbon, 2) a benzothiazole group having an aromatic hydrocarbon or an aliphatic hydrocarbon, or 3) a -SO₃-Na⁻ group. 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) 1-10 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hu et al (CN115572416). In setting forth this rejection a machine translation of CN115572416 has been relied upon and all citations to paragraph numbers in the discussion below are with respect to the machine translation. Hu teaches a composition comprising 100 parts of a diene rubber, 5.6 parts of an activator such as zinc stearate, 1 part of an accelerator such as 1,6-bis(N,N'-dibenzothiazolecarbamoyldithio)hexane, 2 parts of sulfur [0013-0014, example 1].
